Little Manatee River State Park K-1898

I had some time today and wanted to get out of the city here in Tampa so I went to Little Manatee River State Park and setup a quick little activation on 15 meters.

This park is really nice and well cared for. It has many hiking trails as well as a creek on one side that you can canoe in…just dont pet the alligators and you will be fine there, but they do have an equestrian area as well. Plenty to do if you want to do something other than park activations for some reason…lol

Today saw me setup on the bed cover agian as it was nice out and I was mostly in the shade so I knew I wouldnt get too hot. I ran CW only as I didn’t feel like messing with the sBitx V3 to work FT8 as I really only had about 30 minutes of operating time and for me, the FT8 contacts come in a little slower than the CW contacts. I did choose 15 meters though which was a little bit of a gamble, but it worked out once I got on the air and tuned around the band a little and found it was active, I rested a little easier.

I ran the Ten Tec Argonaut 5 transceiver today with the N3ZN key and Hamgadgets memory keyer. This radio is a joy to use for CW and I really enjoy using it for park activations. It has about 20 watts full output, but today I was only running 15 watts as I normally don’t push the old transistors as hard as when they are new… probably don’t matter, but in my mind it makes sense. When I am operating, I use 3 things, well 4 if you count the AF gain (volume). I use the multi-function knob to control the BW (band width of the filter) and the RIT control. The same knob does both jobs, you just hit which ever button you need first then set that function to what you want. The display is currently showing the BW setting of 600 Hz. I will open it up if the band is quiet, but this thing is pretty selective and will allow me to go down to 250 or 300 Hz if I need it and works really well.

Today also saw the use of zero radials. I wanted to see what the SWR would be without anything since these antennae are designed to be used without a counterpoise and just work off the coax shield and car body. I was pleasantly surprised when the nanoVNA showed 1.3 to 1 right out of the chute! Seems my antenna for the band is tuned a little low like this. If I add the 20 meter radials it balances better and move the frequency up closer to where I operate and gets that super deep null right on me.

I did experiment a little with how I laid out the coax to see what it would do and the result was minimal to say anything. I think I changed the reading by .01 SWR from start to finish. Totally not worth the extra effort to optimize the coax… The photo below shows me pointing at the best setup I found and the screen of the VNA showing my target frequency on a 4Mhz slice of spectrum.

I had problems with RF in my keyline. I am guessing due to the proximity of my key and keyer to the antenna. With electronic keying, rf can trigger the keying circuit adding unwanted dots and dashes to your code. I solved this by adding rf chokes to literally everything. If you will notice they are on the key cable as well as the keyer to radio cable and I still have that huge one on the coax as well. I have not added them to the power cables yet but might to see if it will help.

At the end of the day, all POTA is good POTA and I had a wonderful time working a ton of stations. The Ten Tec Argonaut 5 is a great little radio and I count my blessing for being able to land one for reasonable money. If you are a CW guy, then I suggest you try some of the Ten Tec radios as they are simply sublime machines for this mody. I quickly became an addict of their radios and will continue to be for many years to come. Thanks and I hope you get on the air and have some fun soon!

Back in Florida and at a park!!!

Since I am down in Florida for a little while and I am finally going to Hamcation, I thought I would do some POTA as well. Today I had a few hours to spare so I went out to K-1829

This is a new “to me” park so I was a little excited to see what it would be like. When I first looked it up, I noticed it has a check in station at the entrance of the park and a campground and lots of trails. This park is quite large too so it was going to be interesting to see where I could find a spot to setup. With gated entrances and check in stations, these parks usually charge a fee to enter them. Not so here, well sort of… You see, as I was getting near the entrance, I noticed this equestrian parking area and when I checked the map, it was fully within the park boundries. I checked the board for parking rules and there were no rules like payment needed or any specific place or anything like that, so I pulled in here as it was right off the main road.

Once I found a spot under a shade tree, I started thinking about what band to start on. I settled on the highest band I have a hamstick for…15 meters.

This is where I learned something today about the setup that I didn’t know before. The coax is what makes this antenna resonant on 15 meters. Yep ,I put the common mode choke at the base of the antenna and the SWR was 1.4 to 1. Move the choke to the other end of the coax and it was 1.021 to 1! I guess I tuned it with this piece of coax in this position or something as I had deployed the 20 meter radials and then the 30 meter radials to help and wiht just the 20 meter radials, the SWR was 1.65 to 1. This is technically usable, but I prefer it to be a better match to the transmitter output impedance, so I kept experimenting till I figured it out.

Below shows the first radio I used today. The TenTec Argonaut 5 is a wonderful little radio. Since I like CW for my activations, this is a great radio for me. I don’t even have a hand mic in the kit (I should change that to be honest)… Today saw me also as the MFJ 941C antenna tuner as well. I don’t need this tuner with my hamsticks as they are resonant antennas, but I wanted to play around with the SWR meter a little and this also allows me to keep an eye on the antenna system too as I can see the SWR changing in real time this was way. The Argonaut 5 has no built in SWR meter so this fixes that shortcoming for me.

Today also saw the re-emergence of my N3ZN CW key as will. It is a wonderful little key and works like a dream. I run this key through a Ham Gadgets memory keyer for my POTA ops. I store all four memory locations with useful data to streamline my activations. I also have two different cables to connect it to the radio with as well. One goes into the back where the traditional key input goes and the other is a hybrid cable that connects to the mic jack on the front of the radio. You can see it in the above photo with the noise suppression toroid inline. I have been so stuck on the sbitx radio lately that I had forgotten how fun it was to use this little radio.

After I worked a bunch of CW contacts, I moved up to the Ft8 part of the band and changed radios so I could work some FT8 contacts while I wrote out my log in HAMRS. Since FT8 is relatively hands off, I can get my log file for the POTA site done while getting some contacts on FT8 as well. I was able to get 19 digital contacts in the log today like this before I ran out of time. Not too bad for a guy who doesn’t know much about digital modes.

Here is a hint about the sbitx. Don’t forget to update the grid in your settings file before you start or you will be handing out the wrong grid… That one is free. Lol.

The one thing about Florida parks that is very different from back home is the presence of aligators in the water. Back home, it is nothing to goto the river with your friends in the summer and go swimming, but here that is a risky proposition. The park warns of it and I am pretty sure that is what I saw out in the water before I left for the day as well. It is hard to tell in this photo but there is a tiny object right in the middle of frame below that was moving in odd patterns around in the middle of the water, could have been a log, but my mind wants to say it was a gator…lol.

Here is another subject I learned about today you might say. I wanted to see how much difference it would make to move the common mode choke from one end of the coax to the other on my 15 meter hamstick as I am pretty sure I tuned it with the choke at the transceiver end of the line. Well, it made a huge difference to be honest about it.

The ground plane makes a huge difference if you plan to run resonant antennas, just keep that in mind while you are tuning up your system. EVERY device in the line will factor into the system impedance and is important. Dont forget that.

The log today shows of many Canadians as well as a Belgian too! I was really stoked to get them into the log as well as Utah and Idaho, those are all pretty long trips for 15 watts and a hamstick, but they made the trip! I am constantly amazed at what you can do with these little diminutive antennas to be honest about it. Just goes to show that about anything that will tune up (with or without a tuner) will radiate a signal and can make contacts. You hear about people having to load their gutters because of covenants restricting antennas and I dont doubt that they make a ton of contacts with them.

All in all, I see that there was no need to get the other antennas out at all. There was plenty going on up on the 15 meter band so I never bothered to move off the band. It was a great time and I hope to replicate it again soon.

Until then 73,

How well does 17 meters work?

I see a lot of people on 20 meters, but what about 17 meters? I take the sBitx v3 to Cloudland Canyon State Park (K-2169) for a little fun on 17 meters today…

sBitx V3 running FT8 natively on 17 meters.

The WARC (World Amateur Radio Conference) bands are nestled between the typical bands and everyone knows what they are because it is on the license tests. The ones I am referring to, in case you forgot for some reason, are 30 meters, 17 meters and 12 meters.

What the license test doesn’t teach though is that each band has unique characteristics that make it fun to use…at least that is how I see it. Since each of these WARC bands are stuffed between other typical ham bands, they seem to take on the characteristics of the two bands they sit between. Take 30 meters for instance, it will act like 40 meters with NVIS propagation on my hamstick to work hams just a couple hundred miles away and then I will work the west coast on the very next contact as if it were also a 20 meter contact.

Well, the higher the bands get the further they tend to reach more distant stations for me. I don’t have giant towers that have huge Yagi antennas on them for say 40 meters so my results are more of the typical ham who might have a dipole that is technically too low to the ground for textbook operation or a vertical with a couple of radials…you get the idea.

The 17 meter band has the same characteristics as 20 meters as well as 15 meters a lot of the time. For me the higher the band, the better the DX usually. I guess it has to do with the fact that the higher the frequency, the smaller the antenna and with a smaller antenna, the lower it can be to the ground and still have proper performance. Armed with this VERY basic knowledge of antenna theory, I usually expect some cool European stations on 15, 12 and 10 with the occasional DX on 17 meters, but today the sky was alive! Well, it would fade in and out and you can see it in my logbook reports. The signals reports over the time period of the activation go from 599 both ways to dismal 529 and 229 reports within an hour. This has been the norm as of late too, a lot of my activations lately have had events that would be described as cyclic in nature. I would hear a station call and reply to them with a 599 because they were booming in and then when I turn it over to them to reply, they will be a lot weaker and then you can literally hear them fade out while you watch and then fade back in by the time they turn it back over to me. It is really odd to hear that in real time for some reason.

When I got to the spot I wanted to use for the activation, I was the only one there. So I setup in my usual spot and figured I would start on 17 meters to see how things were and if it wasn’t really happening, I could move down to 20 meters and get the activation easily there. I should have known things were going to be good when my first station of the day was VK3AWA!

Now you need to know something about me here. I thought this was a Canadian station since the call started with a “V”. I work so many Canadians that I have become accustomed to hearing the V callsigns and happily add them to the log. It wasn’t till I checked the QSO map that I realized that he was actually in Australia!!! They (it is an Australian club call) must have had a Yagi antenna pointed at me or something, along with a path opening as the signal reports were really good for a 12 watt transmitter running into a ham stick antenna on the back of a pickup truck. This contact was on FT8 and FT8 reads the signal strength in dB with the software to get the most accurate reading possible to send back. So it isn’t quite as subjective as something like CW where a lot of people (me included) will send signal reports based on how the op sounds to them and never reference a meter one time… So for my little radio to get a -8dB report from Australia had to have help from the atmosphere and probably a very good antenna on their end.

FT8 is a relatively new mode for me. I have normally not done anything other than the two original modes of CW and voice. For me to reach out into a new mode is a pretty big deal and this one works really well, which is why I like it. I am also looking to start messing around with PSK 31 some as well as possibly RTTY if I can figure out how to get the little radio to do it. I think PSK 31 will be pretty easy to master, so I will tackle it first.

The above map shows the performance you can normally expect from a band like 17 meters. Notice there is practically no contacts inside of about 600 miles other than two oddities here in Georgia? That is because of the antenna and the ability of 17 meters to have a pretty decent take off angle and also to reflect off the ionosphere easily. This garnered me a ton of contacts in the pacific northwest as well as the Atlantic north east and a scattering around the country to include Utah and southern California. Then there is the EU… I made several contacts with France and Germany today. That has been a little unusual lately for me and my system to be honest so I was stoked to see them in the log.

But this trip did something that I had not done before that I can remember… It netted 7 Canadian QSOs alone, combined with the other DX calls I technically activated today with only the DX contacts! That has to be a personal first.

I started with a DX call and finished with a DX call. How cool is that? It was a great day for radio and I really enjoyed using the sBitx with the new V3 firmware. The radio works so much better than the previous firmware and the FT8 is a breeze in the native radio setup. It you are into smaller radios and smaller companies and the idea of help from a collective of literal geniuses that willingly share their information with you, then this just might be a radio you will like. It is for me, I have had so much fun with it that it is hard to understand how I got along without it before…and the people over at HFSignals dont even know who I am…haha.

Winter Field Day

It’s that time again. Winter Field Day is just as big of an event for the Dade County Amateur Radio Group as regular Field Day is in June.

We have used the New Home Community Center for a long time now and I want to thank Kevin for his efforts to keep it open for us. Here he is telling everyone something interesting while I take a selfie.

This year it was really warm on the Saturday of the event due to some sort of weather system that had moved in so it was really foggy at times (see the photo of my antenna on the truck below) and rainy at times, but I would rather have this over the cold. Well, that was Saturday, Sunday showed up with the AC on high as it was 43 in the AM and wet from the rain and the temp dropped continuously over the day as well. Not cool…errrr, I mean ….not fun!

Another thing about these events is that there is always something good to eat nearby!

Below we have several people setting up antennas and just being around for photos and such that were having a great time! I missed a couple of people somehow, so I hope they dont mind not being included in the blog…like W4EMA, I really dont know how I missed getting his photo, I kept having to walk past him… figures.

Roger KG4WBI (above) stopped by to visit even though he was still getting over the crud. He is always a wealth of knowledge about all sorts of things.

Below is Todd KK4YLF with his beautiful station he setup. This machine had a touch screen and all sorts of other tricks up it’s sleeve to allow it to work really well. It was impressive to see it setup for a field day site to say the least.

Alright Hollis, what is going on here? Lol. You look WAY to comfortable. LOL…

Below Josh is working some HF SSB on his FT891 into an EFHW and it worked well. How well? I’ll get to that in a little bit. There were stations setup everywhere this time.

Above is a photo of the display on the sBitx where we was using FT8 (yes, I now know this is not an allowed mode for winter field day…now, I guess I should read the rules more carefully first) and making contact with ZD7Z. This was a particular exciting QSO for us as we had randomly just hopped on 15 meters since no one else was up that high on their radios and he was the only station on the air up there. So we figured why not try to get a QSO? He actually heard us! We were blown away at this as we had a small radio on a wire antenna (Josh’s EFHW that I mentioned earlier) with expedient rigging and it still worked. We played around for a while and made several contacts on FT8 after that and could hear many more in other areas…and on a different band. Seems there was some sort of contest happening somewhere else at the same time and I mixed that up at times. Live and learn.

When I arrived, I just threw the radio together on the bed cover as the rain had stopped and wanted to play with it some so I made something like 20 FT8 contacts on it before I shut it down for the afternoon with many being in Europe as well as North America. It was a great day and this blog post didnt have quite as much dialog in it as usual, but there were a lot more photos this time so there is that. I hope you have a great day and till next time, 73.

Addendum: I have one more photo to share. Kevin got a photo of me as well as Ricky and Josh so W4EMA is now in the blog! Thanks Kevin, for the photo!

Broken antennas and a quick activation at K-2169 is what ham radio is all about!

I started today’s activation at the Sitton’s Gulch parking area. This is a quick access location for me as it is only about 15 minutes from my house to this spot.

First thing I had to do before the activation though was make a new center conductor for my hamstick mount. Since I made the truck mount out of thicker flat bar stainless steel in the machine shop, it didn’t occur to me that the antenna adapter is going to be too short. Well, it was and I ended up stripping out the last 2 threads on the stud because that was all that was holding it together. Problem here was that I couldn’t reuse it like it was, enter the machine shop at this point.

Below shows the arbor press pushing out the center conductor from the mount itself. This turned out to be a fairly straight forward affair as well, which was nice.

Once out of the arbor press, I was able to examine it more closely. It is a simple part so I decided to make a new one out of bar stock. I dug around in a couple of bins and came up with some brass bar stock and set it up in the lathe and proceeded to cut out a new center stud that was the right size for my needs…

Here we have the new part coming out of the bar and all the unneeded parts (chips) flying off at high speed! Lol. I love machining brass, it is such a joy to work with compared to stainless steel or titanium… Since the stud is press fitted into the body I really had to watch a couple of the dimensions to make sure they would fit properly, but several were pretty loose and were really not critical so I was able to get this part cut out in about an hour total, which for me isn’t too bad.

The solution was to make a new stud that is .200” longer thus allowing for the thickness of my mount. I simply replicated the same measurements, other than the length of the threads, and pressed it back into the housing and now I have an antenna mount with the correct amount of threads for my particular application. I also did one other thing too, I hand fitted the threads to the coupler that screws onto it, this gives me the best possible thread fit between these two part as well as the strongest fit as well. Since I know this is the only place these two devices will ever be together I don’t think it will turn out to be a problem later should there be some need to use it with another setup.

With it repaired and installed on the riser frame, I can now get back on the air and stay warm in the truck too!

Something of note in the below photo is that I use the nanoVNA to check my antenna every time I setup now (or as often as possible as long as I have it with me and it is charged up). I have found some odd stuff a couple of times too because of it. This is how I found the broken coax center conductor a while back as well as some band Sta-kon connectors on my radials a couple of times.

I will even use it between band changes just to see what the SWR is going to be like in a certain band location now. It is a really handy little tool. I highly recommend you picking one of these up and learning a little about it at some point, they are fairly inexpensive compared to the antenna analyzers and will give you the same information plus some. It just takes a little time with YouTube and some patience…

Once the antenna was deployed, I got back in the truck and powered up the radio to see if there was anything going on and boy was there! In this photo I am working FT8 on 15meters and as you can see the band was not very active with FT8 operators (you can see it on the waterfall). No one answered me, probably because they couldn’t hear me very well compared to other ops, and after a while I decided to see if there was any CW contacts on 15. After several minutes of calling CQ, I had netted just two contacts. These two showed how good 15 meters is for distance though with both of them being a great distance away from my park. So sometimes the band just isnt there for you to make contacts even if the RBN says it is.

All that aside, I started on 20 meters as it is my goto band if I dont have a lot of time. If you have been reading my blog posts for a while, you will know this, so here I am on 20 meters and I decide to start on CW this time and see what I can find. I get my spot on the POTA site and off we go, it didnt take long to secure the activation and then some and once I had cleared the little pile up I had going I decided to hop on FT8 to see what I could do. FT8 went really well there to with me netting 14 QSOs there as well before I decided to move up to 15 meters. What I really like about FT8 is that it is pretty hands off, this allowed me to fill out me log on HAMRS and get it caught up to the most recent QSO before I finished out this mode and changed bands. That is really cool in my book.

Now that I have the wiring in the doors repaired I am able to route the antenna coax though the window the easy way as long as it isn’t raining… This is really fast and doesn’t pinch the coax like running it through the door jamb does when I operate in the rain. You really don’t know how convenient this is till you don’t have access to a feature like windows that roll down… It is almost comical how long I put off repairing the wiring in the two back doors and to be honest, it really wasnt that hard either…live and learn.

In the above screenshot you can see that there was plenty of signal but there just wasn’t many CW ops on the band. I did get one Canadian and Paul up in Idaho before going QRT though. I was happy to get at least a couple of contacts once I setup on the band. It is always interesting to see what the range of a band is when the higher bands are open. I have gotten some pretty long distance stuff with some really bad antennas on 10, 12 and 15 meters in the past. It just takes going up to those bands and looking around and the right time of day for it to work…the band has to be open too, but we all know that at this point…lol.

Today’s key was the Gemini Ham Radio travel key, This little key is great for me as it is the perfect size for my hand and I really like how it collapses into the housing for travel. When you take it apart, you see how simple the design is and that you don’t have to have this super complex device to send good code. This thing really is pretty simple and it works great.

Below shows the radial field I laid out today and this was just to give it something to work with as they are all on the same side of the truck! I used one of my tuned 20 meter radials and the set of 17 meter radials and this gave me great SWR on 15 and 20 meters. I like it when this works out… Of course, since I am using a ham stick, the truck body is part of the ground plane and the radials interact with it so the SWR will depend on where I put the radials. This is why I always attempt to put them at right angles to the mount if at all possible as this is how I tuned them initially and also allows me to adjust SWR somewhat by simply moving them around behind the truck.

This is also a first for me as my log shows almost as many FT8 contacts as CW contacts. (14) FT8 contacts and (19) CW contacts is a good day when you only have an hour and a half or so to operate. I have never been one to try to get hundreds of contacts in one outing, even though it has happened a couple of times, I am more about just getting on the air and having some fun. So at some point I hope to work you on one of my POTA trips!

Activated Cold Mtn K-6895 TWICE

Here is the AAR for two separate activations over a two day period at the same park. This is Cold Mountain State Gameland near Waynesville NC. K-6895. It is a great place to do some vehicle mounted POTA and I recommend it.

In this photo above you can see the entrance to the parking lot and how small this area is. I also ran out a single radial on the first trip as I was only going to be on 20 meters as this park doesn’t have cell coverage. I also didn’t know how well I would be able to do with this park as I did literally zero scouting before hand. I scheduled the activation as I wasn’t sure about cell service and this turned out to be a good thing.

I have learned to search out parking lots that are fully within the park boundaries. I do this by pulling the park up on a couple of map applications and then zooming in on the roads around them and scouring these areas for parking lots. Just like in these two screen shots I found the park boundaries pass over Lake Logan road a few times and upon closer inspection, I found what I was searching for… A parking lot within the park boundaries that I can operate out of the truck with is a luxury that I love to land on if at all possible. I didn’t take a man portable rig this time as I wasn’t thinking about POTA being the main reason for this trip but rather something to do if the weather got bad or I just got a hankering for some radio time (which is what happened)…

The radio for today was the sBitx v2 and I am learning more and more about it as I use it. The message memory is really nice with this machine. I really like the whole process of operating CW with this radio and FT8 as well. It is almost effortless. The dev that wrote the code for this radio is working on a v3 release… I guess is the version. I am not sure what version we are on at this point to be honest, but it does have a couple of issues that make it less fun to use at times, but to be honest about it I have had a blast with this radio.

Day 1 was nice because there wasnt anyone except a fly fisherman who was down in the river. Here you can see the radial ran out to the side.

Since I had come to this park and didnt know much about it other than it was a game reserve, it was nice to see that amateur radio wasn’t on the prohibited list of activities. Lol. Keep those activations low key and it probably won’t get added too.

Things got dark in a hurry since it was overcast as well. I ended up finishing the activation by flashlight. Here is a photography trick for you. Dont point the light directly at the thing you are using (here it is the logbook) but point it at the ceiling and the light will bounce back and fill the area making it easier to see and work.

Day 2…

The next day showed more fishermen than the previous day but still there was plenty of room to put out some wire radials. Today I wanted to get on 30 meters and see what I could do as the band was open… or so I thought. So I put out the radials for 30 meters and since they would reach the trees, I ran then horizontal from the antenna mount to see how they would perform as elevated radials. Turns out that was a terrible idea, the SWR was horrendous so I started playing with them a little. I next just laid them in the grass to do it the lazy way and the SWR still wasnt great, better but still fairly high. Lastly, I put down a stake and pulled just one wire taught and BAM 1:1 SWR! Seriously, that was all I had to do???

So I also scheduled this activation as well, but unbeknownst to me, I failed to convert local time to UTC time so the schedule was way off. So I was running dark mode. I called CQ on 30 meters and in ten minutes or so had made a whopping 2 contacts. At one poi t someone tunes up on top of me and starts calling cq as well! Lol. So I figured I would switch over to FT8 and see if the time was still synced well enough for it to work. Ten minutes into this I had successfully made two more QSOs for the log.

At this point I switch antennas and get on 20 meters CW and start calling CQ. I actually think at this point that the spot was working and there just wasnt anyone on 30 meters as I started getting QSOs in the log like normal but then it just fell off again and I decided to try 20meters FT8 and see what would happen and again I only made a couple of QSOs. Not sure why but it is what it is. I am happy at this point as I have the activation in the bag but still have a ton of time so I go back to 30 meters and the waterfall is covered up in activity. I am stoked! I setup and strt calling CQ… and I call…and I call and FINALLY I get an answer.

Over the next 12 minutes or so I work 3 contacts withthe band covered in activity. So I simply ask W4ELP if he would spot me and he said he would. Thank you Ed for the spot because you can see what one simple little thing loke a spot on the POTA website can do for an activation. QSO #19 is Ed and in about 35 minutes had made 19 contacts. This is awesome considering the lack of a spot on the network. As you can see, having the spot though got the word out and I quickly added another 36 QSOs to the log with a couple coming with nice little pile ups.

I learned a valuable lesson today in the I need to check the time on my scheduled activation carefully so it happens at the time I am there. Lol. The next one did happen right. Just like the Smokey Mtn National Park one. The RBN works great and scheduled activations making not having internet access a moot point. This is a fairly new practice for me so I plan to use it more in the future.

All in all I had a great trip to Cold Mountain and will probably go back the next time I go to Maggie Valley to photograph the elk heard since it is so close to the motel. Thanks for coming along and I hope to work you soon!

Activating K-2169 and some notes about radials and SWR that I saw today...

Ok. Radials

Today saw the use of the sBitx v2 again as I wanted to work some FT8 as well as CW. I setup at the frisbee golf parking lot on top of the hill and decide to measure the SWR plot as well as check to see the Smith plot as well of the ham stick antenna and add counter poise wires till it quit making it better. I did this because I received a comment from a ham asking about any info I might have onthis subject since he is wanting to pick up a ham stick and mess around with it.

In the above photo, we have the ham stick on the receiver hitch mount that elevates the radiator to about 6’ to the bottom of the antenna. The antenna is only wired to the cab of the truck with a 15’ piece of coax and it terminates into the nanoVNA through a common mode choke. At this point I had not turned on the 2nd trace to see the smith chart…sorry about that. In all fairness, this could be used on the air with practically no worries, I would probably turn the power down to prevent heating of the finals from the SWR, but that is me being cautious. This is completely usable to be honest.

In the above image I have added a single, approximately 15’, radial and ran it straight out away from the back of the truck. This is completely usable and I have had great activations with just this one counter poise wire. Dropping from 1.574:1 down to 1.226:1 doesn’t sound like much but it really is when you are working towards a resonant antenna. Also notice how the null point is climbing in frequency as the radial field grows under the antenna.

In this photo we see the SWR plot has gotten spectacular! I added the tuned radials for the 17m antenna to the one radial I already had installed so now I am using three radials with the antenna and look at that plot. I arranged them 90 degrees apart as this also matters. The more this angle changes the more the SWR changes too. Sometimes for the better, sometimes for the worse. Notice how it raised the frequency of resonance as I added counter poise wires to the system and it lowered the SWR to 1.028:1 as well as made the antenna slightly inductive instead of capacitive. This shows that the radials are more than simply a ground path but rather part of the tuned circuit that matches the radios transmit frequency and improved that whole system. If you have the space and time, I highly recommend adding counterpoise wires to your system and measuring it with something like a nanoVNA.

Another thing I learned is that I get best performance when the wires are pulled snug as you see in the photo above. I think this might have something to do with when I originally set it all up, I tuned them with them under tension like this which makes the wires the longest and also this changes the capacitance and inductance of the radial from just being thrown on the ground. As a matter of fact, it was when I tensioned the radial shown above that the SWR plot bottomed out like you see. It was the last one to be tightened and it made a huge difference.

By parking in this location I am able to get the radial at almost a 45 degree angle to the antenna or very near it. This matters as it is the point in the radiation pattern where to get a 50 ohm impedance match to the coax feeding it. There is tons of information out there on how to adjust the impedance of the antenna by adjust the angle of the radials…it is like some sort of dark magic to be honest.

I got on the air and started on 15 meters as it looked promising today with the noise floor being good and FT8 being quite active. As you can see though it took me quite some time to get just 6 QSOs in the log. After I worked N7ZLD I went over 20 minutes without a single call, that was when I decided to jump on FT8 to see if I could get a few in the log like that. It was slow going, but that it the fault of the radio software more than band conditions so I was happy to get 4 FT8 QSOs in the log, securing the activation only on 15 meters for a change!

After playing on 15 meters for a while I decided to see what 20 meters sounded like (I didn’t even check the antenna, I just plugged it in and got on with the activation). I quickly found myself in a small pileup working through several call and the calls kept coming in for a good while one after the other and sometimes two at once. This is the pace I really like as I don’t feel like I am missing anyone that wants the park I am at. After a great run on 20 meters CW I once again switched over to FT8 to see if I could get a few there. It took me a while to get someone on the hook, but I did work 5 more and the last one was W0NKA!!! That is (W -zero- NKA) and he is awesome, go look him up on QRZ and see about the special event he is having in December where you can get the golden ticket!

All in all it was a wonderful activation and I hope you enjoyed following along today, until next time I hope to hear you on the air.

Activated a new-to-me park today! K-3958

Today was a good day for POTA. I activated North Chickamauga Creek Wildlife Management Area and it was fun! You see, for me to get 80 QSOs in one outing recorded into the log is a feat of the airwaves, so that made this trip one for the books!

K-3958 is also just outside of Soddy Daisy Tennessee at the foot of Mobray mountain. I was concerned when I chose this park that I would have trouble securing the activation as this parking area is right at the base of the previously mentioned mountain. I decided to give it a shot anyway though since I have had great activations at Cloudland in a similar scenario. This WMA is also situated is a gorge and goes right up to the side of the road, the problem is unlike K-0716 on the north end of Lookout mtn where there is a pulloff, this park doesn’t have one on the road. This means my only shot at activating this park today was to find a spot inside the actual parking area itself.

So I roll into the parking lot and start looking for a space that would be suitable for setting up a station out of the truck. I quickly realized that since it was Saturday and near town that it was a popular “waterpark” for the local youth. The lot was almost COMPLETELY full with only a few spaces that were not suitable for most cars. Since I drive a huge 4x4 truck though, this problem posed little challenge for me. I soon found the spot you see in the photos and got started building a radio station. I had just enough room to fit into this space too as you see here, the truck just did clear the trees.

Well, this was kinda tough as to get out of the road, I had to back right up to the bushes. So here I am, bushwhacking my way around the back of the truck as I get out the mount, antennas and run a coax to the cab of the truck. I ran the station from the front seat today in an effort to keep dust under control as the road is literally 7 feet away and is gravel. Compound this with people driving pretty fast as well and it was fairly dusty at times. This was the main reason for giving up on the outside station idea today.

Once setup, I start considering my plan, I figured that I would start on 20 meters so I could be sure to get enough QSOs to secure the activation as the spot page showed a disproportionate amount of activity on this band. Well, let me tell you that my fears about not being able to make contact from this location were completely unfounded. This location could hear just fine. I setup on 20 meters and start calling CQ and it didnt take long at all to get a run of contacts in the log that secured the activation! After that they just kept going and going and going!

Parking is kinda tough here, you have to get the right spot for POTA and on a nice Saturday, this lot is FULL, I recommend coming through the week so there is more room.

This is what the parking lot looked like. Just cars pulled out of the way of moving traffic on the side of the road for the most part. Some spaces were built into the tree line like where I parked and then a ton were like this photo above. Almost all of them had cars in them too. The ones in the trees that were open also normally has something that made a car being there a bad idea, like mine had this huge rock in it but I had enough ground clearance to fit anyway so it all worked out

Today’s weapon of choice was the Ten Tec Argonaut 5 feeding into my hamstick collection. This is one of my all time favorite radios even though it is larger than my other rigs. It is capable of 20 watts but I never run it that hard with 15 watts being my personal maximum output power. Today saw it running at that 15 watt level because I was thinking I needed it to get over Mobray mountain since I was setup literally right at the foot of it. Across the road from where I was setup it starts going uphill and goes straight up the side of the mountain. In my opinion, this is probably the worst possible location to setup a radio, but it worked today so I am not going to complain…

I have found that the hard shell case for the radio makes a great table to sit it on. I like to use the radio in the passenger seat when I run solo ops (which is most of the time). I like this operating position as it allows me to sit comfortably in the truck and operate. This keeps me out of the sun, and I can activate in the rain from this position as well. The Dodge arm rest in the 2005 year model is a huge flat surface too so it turns into a nice little table. Since it is vinyl upholstered, the key doesn’t move around at all on it either, making this the almost perfect work surface for my POTA fun time shenanigans! If you will notice, the window behind the radio was only slightly down. This is because I was trying to minimize the dust buildup in the truck from people flying by right in front of me, there seemed to be no shortage of fast drivers in this tight area for some reason…

Well I sat on 20 meters for about an hour and made contacts the WHOLE TIME! Wow! The hunters were out in force today!!! I made FOURTY NINE QSOs in just over an hour!!! That is awesome! I looked at the POTA page for this park and that one thing alone put me on the top five activator QSO board. It is going to be a great day for the WK4DS POTA operation…

So at this point the QSO rate had dropped off and I figured I would try 17 meters to see what I could do there. Well, there was RF in the shack on this band and this little PICO Keyer is not RF friendly…at all, if there is RF near it, it will start sending strange characters and it would do this on 17 meters today, this told me the SWR was probably a little high due to the position of the counterpoise and so I folded on 17 and went instead to 30 meters.

The nice thing about 30 meters is that it allows you to operate into areas that is only reachable by BOTH 20 and 40 meters. It is strange in that it acts like both bands for some reason. I can make long distance contacts and then the next one will be in Georgia… You just never know with 30 meters how it will work. Well today it worked REALLY well, with me making 28 QSOs on this band in about the same number of minutes. The bands were on fire today! Wow! It did get me quite a few local states as well with North Carolina, Tennessee, Georgia, Alabama and Mississippi coming into the log at this point.

The photos above show what everybody was coming to see. The river is beautiful but the water was way down with only a small stream actually running right now and that made for several pools that the people would congregate around to swim in. I found a couple of fishermen at this spot and they said they were not having any luck due to the low water levels. I grabbed a couple of quick photos and headed back to the truck…

After having such good runs on 20 and 30 meters I figured I would drop down to 40 meters and see what was going on there. Forty meters was not happy today, well at this point in the day that is. Seems that the atmosphere was not happy with my attempt at this band and only allowed me 3 QSOs before I called it quits and went QRT with 80 QSOs in the log for one day. I wrapped up the radio and antenna system and then headed home with a new park and a ton of contacts, what else do you need for a great day of radio? I will go back to this park again but next time I want to go on a week day and see what I can do with less people in the park. But until then, I hope to hear you on the air. 73 WK4DS

A POTA activation that was incredibly rewarding!!!

When we activate a park we never know what is going to happen.

So today is Labor day here in the USA. This is the first Monday in September set aside for the workers of this country to grill out with their buddies and such as that. So for me that means going out and setting up a POTA activation somewhere. I decided on Cloudland Canyon after deciding that the drive time to other parks would make the activation very short for me and I wanted more time on the air instead. I choose the upper parking lot since I wanted to use my hamstick system instead of rigging to the trees today. The trees I normally use have a lot of traffic today from hikers and I didn’t want them tripping over antenna wires all day so this just made sense. As you can see below, there was plenty of room for me here today…

I don’t know if I have shared this or not, but I have converted all of my hamsticks to this QD system so band changes are fast. It works really well, I do need to retune my antennas though as this did lengthen them a little and now they are all low on the meter for their center frequency… always something to do…lol.

Once installed, these mounts work really well and the tune is very stable, I have not seen it change at all from the numbers on the VNA since adding these QD adapters. So if you think you might want to use hamsticks for POTA, I really like them. Now to be honest, I don’t think I would use them for mobile (in motion on the roadway) use as there is a lot of leverage on this little mount and the spring is not that heavy to me, they might work fine like that and probably have been deployed that way, but for me, this is a site setup tool only.

Another reason for the hamstick setup is the use of the truck for shade during the activation. By strategic positioning of the truck I can leave the doors open with the engine off and not have RFI from the operating parts of the truck to contend with as well as having a natural shade from the sun too. I use this trick a lot when I don’t have a ton of time for an activation and want to operate in inclement weather like rain. Simple and robust, plus the system just works, look at the logbook below and tell me how hamsticks don’t work…

I carry all of the stuff in the photo below in the hard-shell case that I keep the Ten Tec Argonaut 5 in so I don’t have to search for cables or things like my key. It is all in there and I just grab the case and go. This makes life so much simpler for me. Seen in the photo is the Ham-gadgets Pico Keyer and the N3ZN tiny CW key I picked up at the Huntsville Hamfest. Once I get all the parts out of the case I close it up and use it in the passenger seat for the hard surface to place the radio on so it is out of the way while I use the center armrest for logging and sending CW.

Here you can see how simple the connection scheme is when running Hamstick antennas, there is no tuner or interconnecting cables, just the RF choke to the coax, the power cable (I plugged into the truck’s cigarette lighter port today) and the CW key cable and nothing else is needed. Simple is king here and it also makes setup fast. That is another reason I like using CW instead of other digital modes with this radio as well as my other radios to this point. They all need a computer and a sound card to get them to do digital modes (other than CW) and I normally don’t have a ton of time for all that setup and getting it going. CW is on the air really fast, like SSB. You can also see the silent fan mod I did a while back (there is a blog post showing what I did) and I really like this mod as it eliminated the fan noise entirely. I need to make a screen to protect the fan though, that is still a project to be done…

You have seen this view shown below in the past, but I included it today since I got the moon in the photo too… lol. I do like the system I have built for activating a park with a hamstick, it is really fast to deploy and when I do a rove, I simply coil up the counterpoise wires and lay them in the truck bed. pull off the radiator from the QD base and lay it in the bed of the truck too, unplug the coax and coil up the portion to get it inside the truck and I am off to the next park. The antenna mount can ride in the receiver hitch easily enough so it is not an issue. This sounds like a lot but it literally happens in two minutes tops and I am driving to the next park.

Another thing I did today was hook up the inline power meter. Now I don’t remember why it only shows 8.9 watts of output. I had the radio set to 15 watts forward power so I probably took the photo after I let off of the key as the amp hour meter doesn’t clear till you disconnect it from power. I don’t remember if I had it in tune mode or if I was simply sending dashes. But what I was looking for was the total amp hours of use, this tells me if my little 8A/h battery would hold up to a heavy activation. From this meter reading it will. Now remember, this is with the radio set to 15 watts too, so under a normal activation of 5 to 8 watts, this would last for many hours. Today I went for two hours and got 70 contacts in the log and only used 3.68A/h and that makes me much more confident in using the smaller battery for activations now. I had my concerns before but now I don’t. Another point here is that I normally try to add something else to the activation that has to do with information gathering so I also learn something that I didn’t know before, today it was the amp hour info.

So I get to the park and take my time and listen to the bands a few minutes once the rig is installed and decide to start on 40 meters as the noise level was really low today. I get on the air at 13:25 UTC (9:25 local time) and start calling CQ… It didn’t take long to secure the activation and I had not left 40 meters! I don’t get on the lower bands too often as I am not at the park at night when the bands are less noisy so I don’t get the hams in the closer states like Tennessee or Georgia, it was really nice to get some of those states in the log for a change. Hanging out on 15 and 17 meters nets much more distant stations so I have to remember to come back to 40 every once in a while…

I then move to 30 meters for a little while to see what I could do there and work several more people on 30 meters in about ten minutes of operating. 30 meters at this park is a crap shoot to be honest, some days it is quiet and some days it has this intermittent computer noise that just shuts the band down, today the noise was nowhere to be found to my delight!

Then…I…got…on…twenty…

First off, who doesn’t work Bill (K4NYM) if he is booming in to your station and for a Park to Park no less? So I hunted him before setting up on frequency. It took one try, he is an amazing operator and I aspire to operate as efficiently as him some day.

Things take off once I park on a frequency and start calling CQ. I promptly work a page and a half of calls then I get the one you see below. Not one to brush off anyone calling me, I take the time to have a nice QSO with him as he is working on getting on the air with CW and is having to do head copy only…I later learn… So I take the time to write down what he is sending so I can read it and respond when it is my turn. Turns out he is just now getting back active in CW after taking a long hiatus from it and also, he cant see, hence the head copy only. Talk about a person with conviction, he never gave up. I was so glad Justin called me and feel honored he felt confident in me enough to throw his call into the fray of POTA not knowing what would happen. That took guts.

Once we finished our QSO it was back to the POTA game in full swing. I struggled with one thing today more than anything else… stations zero beating me. It never fails, I get two or three stations that due to modern technology, will zero beat me perfectly. This in itself isn’t a problem and is really the most efficient QSO to have in CW, but what happens is that those two or three stations melt together into the one single tone and it is unintelligible. So If I don’t pull you out on the first try, move up or down 30 to 40 hertz, This will make you off frequency enough to sound different and you wont blend with the other stations and I will get you on the first try, this is an old contesting trick and by golly it works, I will have one station that stands out and is clearly definable and the rest is this one huge tone. I never really understood it till I was an activator trying to pull one call out of the mayhem, then I got it. Now when I hunt I leave my XIT or Transmit Incremental Tuning on and set 40 hz high just for this reason.

Once I hit 70 QSOs today I had been on the air for two straight hours so I went QRT and shut down the radio. It was a great activation and I really enjoyed working with a new (relatively speaking) ham on building his CW skills back up to what they were. So till next time get your radio out!!!

Counterpoise testing during a POTA Activation

Today involved some experimentation as well as a POTA activation. I tested some changes to the radials I use on my hamstick system out of curiosity and came away with some interesting results. Read on to see the AAR and the results of this test.

Today was supposed to be a quick little activation and then I was going to do a few other things, but plans are made to be changed from what I can tell as the bands were doing well for me and I stayed longer than I planned. But then the sun can bring that full circle as you will see below.

The operating position today shown above, was on top of the hill at the frisbee golf course and on the bed cover of the truck. Turns out that was somewhat of a bad idea. It just got hotter as the day progressed and the sun quickly came over the door I was using to shade me. This is what ultimately caused me to go QRT when I did as I was having a decent run on 20 meters at the time. It was just plain hot, with the sun seemingly cooking my right ear while I was working ops. I did enjoy working several ops today I have seen in my log before plus some that I have not. I even got a Canadian which is always nice.

This is probably the best image of my 40m hamstick and mount I have ever gotten. With the sun in the right spot, the whole antenna lit up well enough for the camera to get it. The setup is not actually mobile as it requires a counter poise to get it to work it’s best, but wow… it worked really well today, especially well today actually for some reason. I can hear surprisingly well on these tiny HF antennas too. I own three different brands of hamsticks (covering 40, 30, 20, 17 and 15) and can not tell a difference in any of them as far as how well they work. They all just work really well.

These two photos tell a story about what was happening at the location today on 30 meters. When people talk about having RF noise at a location, this is what it looks like on a radio that doesn’t have a waterfall display. The photo above is what the noise floor looked like when the RF noise was not present and the bottom image is what it looked like when it started up. It also was not constant, but appeared to by cyclic in nature as it would spool up and would just be some sort of hash for about 20 seconds and then it would just go away for about 30 seconds maybe longer. I would be able to work one contact and then it would come back and if the hunters were not transmitting with an S9 signal, I couldn’t hear them. This is really frustrating and is one of the reasons I don’t activate 30 meters more than I do. But so it life and how much fun would it be if we never had problems to solve? It would get pretty boring pretty fast… Even with this RF hash coming in and out, I was still able to get 9 calls in the log on 30 meters today so I count that as a win anyway.

The next thing I want to share about today has to do with the antenna system I was using. I have made tuned radials for all of my hamstick except the 15 meter unit (I have not deployed it yet, but soon I will.) I went to a lot of trouble to tune these radials too, with a ton of time at home working on this. Well, it turns out that I didn’t need to do that for the 30 meter hamstick at all. I deployed my nanoVNA today and did some measurements on the hamsticks to confirm nothing has changed with them and figured out something just out of curiosity. Seems that the radials for 40 & 20 meters work just fine on 30 meters too. This means one set of radials for all three of those hamsticks. Next outing I will take the 17 and 15 meter hamsticks and tune them up and see if the same radials will work on them too…fingers crossed. I am always looking for ways to simplify my station setup and the radials has been one of the slowest things to deploy of all the gear for POTA with the hamsticks. So if I can get it down to just the two radials and not having to remember the color codes for them and such I will count that as another win in my book.

The above photo shows that the antenna is fine on the 20 meter CW section, even though it is technically low on the best part of the chart, it is only 1.188:1 where I normally work on the 20 meter band. Well, knowing that, below is what it looks like on 30 meters with the 40/20 meter radials instead of the tuned radials I made up for just for the 30 meter band. Pretty crazy huh? Looks almost identical to the 20 meter chart and even almost matches the 20 meter SWR value. I was blown away by how good this turned out and to think I have never even tried it before today… Another thing I noticed about hamsticks in general is that they act like bandpass filters across the HF spectrum, I did open up the range on the nanoVNA and it does have other nulls IN THE VHF SPACE, but each hamstick has ONLY ONE spot they are resonant at in the 0 - 30mhz spectrum. No multiple harmonics like the EFHW, just one really deep SWR null is all you get. So plan accordingly, but to be honest, it works really well so I am not going to complain. I think this might actually work as a band pass filter but have not had the chance to test it yet. Maybe I will set this up at winter field day and see what it sounds like there. That should do it.

Here is the log from this activation and the signal reports look good for a mismatched antenna on the trailer hitch of my truck. I was using 15 watts though so that might have helped some. I have been sending with more power lately to just play with the Argonaut to see how hot the heat sink gets at various power levels and on CW it barely gets warm at all with 15 watts of RF so I am really happy with that. I am doing this test since i changes the fan a while back to reduce the fan noise as the factory fan is quite loud. I have a blog post showing what I did with this if you are interested in that.

All in all I learned something new and had a great activation at the same time. So till next time go get your radio out and make some contacts on it!

Component failure sucks…

When things dont go right it can be frustrating but when things are like my activation recently they are downright demoralizing…

So I had an evening free and wanted to do some POTA so I decide to setup in the truck with my hamsticks … since it is faster… you know since everything is ready to go. Little did I know what I was about to get into.

So I goto the frisbee golf parking area and get everything out to do an in-truck activation. This is how I operate if it is raining and has worked well for me in the past. I just tape a “rain shield” to the coax connector made from a peanut package with both ends cut out. Haha, reuse at its finest. But today, I didnt need it since it was not raining.

Next I break out the Ten Tec Argonaut 5 and my N3ZN cw key and connect it with my HamGadgets PicoKeyer and I am all set. Another thing with today is I planned to activate with my 8Ah LiFePO4 battery to see if it can handle an activation with the Argonaut 5. I have my inline power meter this time so I can monitor the voltage too. I also can monitor Amp/hour usage but completely forgot to do this since I got wrapped up in other things. I setup this kit in the cab of the truck as you see so that I could sit comfortably while being in the truck. This works really well when I am solo, but gets tougher if I bring someone with me. As you can see below it was up to almost 3 Ah by the time I took this photo. I wished I had thought to get a photo of it at the end to have that data. I guess I will have to do it again… lol.

But before all this got started I connected my antenna and wanted to check the SWR before starting as I have been experimenting with the radials some here lately and have learned some interesting things about them. I get out my nanoVNA and connect it to the antenna and it shows like it isn’t there…at all. I mess with the VNA a while and try to see if it might have a loose adapter on the VNA or if the calibration might have been done wrong, which I found not to be the case after calibrating it again… Nothing in the VNA was wrong, so I get out of the truck and inspect the antenna and it looks right, nothing is out of the ordinary. I go back and get my trusty little multimeter and decide to ohm the center pin of the coax to the shield to see what it measures, it should be open to the meter…it isn’t, quite the opposite actually, it is shorted. So I immediately go to the antenna and disconnect my brand new, reputable brand coax and check it with it removed from the antenna, it measures good now. Whew! That was close! I didn’t want my new coax to be bad right out of the chute.

So now that I am pretty sure it isn’t the coax, I turn my attention to the antenna. I remove the radiator and test the base to center pin and it reads shorted!! What in the world is going on here!?!? I look closely at the mount, which at this point has the BNC to PL259 adapter on it and nothing else and so I remove the top portion of the antenna mount to make sure water has not entered the plate where it passed through and has created a path with corrosion to the mount. Nope, not there, it looks perfect.

So I remove the adapter and the short goes away immediately. I reinstall it and it returns. I remove the adapter and check it and it measures fine and so does the antenna mount now. What gives? Well, I had a new adapter I picked up at the hamfest from the Wireman and I just installed it to see what would happen. The problem vanished. I tried wiggling the antenna and the coax and pushed and pulled on the adapter and the meter didn’t change a bit, all I can figure is that something in the other adapter is shorting when the adapter bottoms out on the antenna mount at the point where it gets tight.

This is what went bad. On the surface from every angle it looks perfect, but when tightened in place it produces a dead short across the antenna to ground. Don’t blindly think that simple things like this can’t fail. Obviously they can. I will be more diligent in checking my system routinely too. The Argonaut 5 has no SWR meter on it, which is pretty much the only thing about it I don’t like, so I have to use other means of monitoring the SWR. The VNA was that tool today.

Once that was sorted out, I was able to get on the air and make some contacts. Since I was dancing with the end of the UTC day, I figured I would start on 20 meters to improve my odds of getting an activation before the day flips over. The hunters came in clutch and I EASILY made the activation. Once I cleared all the calling stations, I QSYed to 17 meters to see what I could do there as the band was open earlier…before I found the bad antenna adapter…

Turns out 17 meters right during grey line to the west coast will net some cool contacts. All but one are from the west coast and that is always fun as I rarely get to work California due to noise on the bands. All in all, I netted 41 contacts in the log all before the UTC day ended. So it all worked out anyway. Moral to the story is two fold. The first one is to take extra parts for your system and two is don’t assume anything… this adapter looked perfect visually but did not work when installed. Have fun y’all and I hope to hear you on the air soon.

PS: Another perk to working POTA is things like these photos I grabbed of the clouds. You normally don’t see these at home in the house. If I had stayed home or threw in the towel on the antenna (which I almost did) I would not have seen these beautiful sunset clouds.

Quickie Activation with some cool DX!

When I started this activation, I had no idea how the bands would act, there has been a lot of QSB lately so it is kinda a crap shoot. I only had about an hour so I figured I would try to get a few contacts… little did I know I was about to have a lot of fun!

God showed his power to me today when I got on 17 meters and started calling CQ. I had gotten my first contact pretty fast and it was another activator, so I got a Park to Park right out of the chute. Then I started hearing this station just up the band from me… I dialed up and found it was a fellow down in Turks and Caicos! I waited till he called CQ and threw my call back to him…and he HEARD IT!!! DX in the log and I am just getting started!!! Woohoo! Then the VERY NEXT QSO was Sweden calling me!!! For me, this is cool dx, as I dont get to work other countries very often, especially with a QRP radio…

If you look close (right beside the key), you can see where I pieced together the call sign for the VP5 call sign. He was going faster than I normally can copy so I grab letters one or two at a time till I build the whole call. Then I listen for the exchange and at that point I am ready to try to call them. I think they were probably running about 25 WPM of maybe just a little faster, and I normally operate at around 18 to 20 WPM…

On this day I used my Penntek TR-35 radio on the bed cover of the truck. This is a fun operating position as I get to interact with other people in the park some as well. On this day, there was a family that wanted to know what all the wires were about so I took a short break and explained what I was doing to them. This is why there is a 10 minute period between contacts 3&4 in the logbook.

Another point about this common mode choke on the TR-35, it is the perfect size to hold up the radio when operating like this… lol. It does look “techie” too so it makes the little station look cool in my opinion. Lol.

The radial connection works really well for the multiple setup like I am using here. This is all the radials to cover all four bands the TR-35 has access to, 40, 30, 20 & 17 meters. This way I only need to switch the verticals to change bands. It is actually really fast like this and I am debating whether or not to make the multiple antenna mount now…

As noted in a previous blog post, I added an Anderson Powerpole socket to the little module for other things to be able to share the power as well. I don’t need it with this radio but it is nice to have when I run my IC-705 as the antenna tuner has it’s own power cable.

So to wrap things up, you never know when the band will open and you can make a 4500 mile contact with your QRP rig on a hamstick till you hook it up and try. So get your radio out and go play with it somewhere. Until next time…

My 80th Activation of K-2169

This AAR is brought to you by… wait for it… me! Lol. But seriously, today is special for another reason or two, on this day I activated Cloudland Canyon State Park for the 80th time and I met another ham at my home park!

Today, once again I setup the truck in the lower lot like I did a while back as it is faster somewhat but also it has a different view as well. I normally don’t setup down here as I have had issues with electronic hash noise in this area (I am guessing it is coming from inverters in the campground just over the hill) so that is why I goto the top of the hill where the disc golfers are most of the time. The antenna situation today is as follows, I went ahead and installed all the radials at once as it was threatening to rain the whole time and would sprinkle on occasion during the activation regularly.

I also used my RG-316 coax today along with my rain proof “countermeasures” which consist of a peanut bag taped over the coax connector to keep it dry during the activation. This is a field expedient solve that also happens to be a way to recycle a common piece of trash that would otherwise end up in the landfill. I can even reuse the tape a couple of times if I am careful.

Since I connected all my radials today, I also tried to use the whole suite of antennas that I have currently. If you will look closely, you will se I also installed QD mounts on my hamsticks as well. This made band changes so much faster!

I figured I would start on 17 meters to see what I could hear up there. When I connected it and saw the radio, I had high hopes as the waterfall on the Icom IC-705 had several signals on it. Calling CQ almost immediately netted 2 dx contacts! I worked DL1AX in Germany and SP9RXP in Poland! Did I mention I am only using 5 watts?!?! SP9RXP is 5060 miles from K-2169 so that qualifies for the 1000 miles per watt award! One day I will actually apply for these… HIHI I attribute this entirely to the new common mode choke I made and was using and a nice little band opening that happened at the same time. The choke probably didn’t have much of an impact on this but I want to believe it did.

This choke works so much better than my other one that it isnt even a real comparison. It also seems to help with band noise, but that could just be me wanting to believe it does since I built it more than anything. I know it measures real good on the nanoVNA… lol

While I was on 20 meters this camper van rolls by real slow, I tend to get that a lot with all the radials and the hamstick on the back of the truck. Then the camper van stops right in front of me and the guy gets out and starts over my way. I also get this a lot as people are curious and want to know what I am doing. But then it takes a completely different direction when he says (I am paraphrasing a little here) “Are you doing Parks on the Air?” This caught me off guard as I had never had someone who knew what I was doing, actually ask me if that was what it was.

Turns out this camper was none other than W5DXQ on vacation! He is from Texas and is very active on the air using an assortment of modes. I was in the middle of a QSO so I asked him to let me clear it then we proceeded to talk for about 20 minutes about my rig and CW and digital modes and how he uses the spotter system and SSB and the list goes on and on. Meeting Jeff was the highlight of the activation…well that and working two dx stations right out of the gate on 17 meters… It was awesome to finally meet someone else who does POTA at a park. I am so glad he decided to stop and ask what I was doing. I hope to work him on the air at some point! Now the challenge for me is to meet someone actually activating like Jeff did when he found me today.

Once we finished our eyeball QSO he headed off on his adventure and I got back on the air. Looking at the QSO map, it looks really odd with the two european stations when compared to the North American dispersion that happened once the band opening closed on 17 meters. I normally net at least a few western states but today saw no one west of Texas.

As you can see from the logbook, today 30 and 20 meters were the bands to use but even then the reports were showing how the bands were fading in and out. I did make some contacts on all four bands though so I am super happy with that.

The peeps over at the POTA website even sent me this cool certificate to commemorate the 80th activation! Nice!

All in all, it was a great day for POTA. I hope to hear you on the air soon. 72 de WK4DS

Today is the day I went roving in POTA parks.

The rover award is when you activate at least 5 parks in one UTC day.

My final location of the day, Booker T Washington State Park K-2933 and it worked wonderfully!

I have been interested in this whole “rover” thing for a while now. So I finally dug into the rules so I would know what is required and laid out a plan. I found 5 parks that I could access easily and set out a route to them and just loaded down the truck with gear in anticipation of needing backup stuff. I didnt need it, but I had it. Like what you see here is three radios. The TR-35 (which is what I used for most of the day), the Icom IC-705, and the Elecraft K1 makes for a strong QRP expedition.

Anyway, so I figure I would start with my local park since I know where the parking lot is and the proximity to the main road is really good. I chose the Sitton Gulch parking lot at the bottom of the mountain because of the main road noted above and the fact that I have had great luck here in the past.

I got the activation, plus a few more contacts than I needed, in about 20 minutes of air time. Not a bad start! Well, I got excited once I cleared the pileup and had the activation in the bag and completely forgot to get a photo of the truck here. I realized it at the next park… If you want to know what that looks like, just read this blog post K-2169 POTA Activation at the very foot of a MOUNTAIN - AAR. It has a few photos of this parking area and I was in that lot.

I wanted to make sure I had enough time to activate each of the five parks AND not leave people calling if at all possible. Since I am using QRP power, this should not be a problem though and I normally dont get more than four or five calling me at once with two being the norm for me. Basically, pile ups are small for me. So I wanted to shave time off of the other parts to leave more time for “ON AIR” activities. Below is a quick photo of the cab of the truck showing how I left the gear when changing parks.

I just left the TR-35 connected and laid it on the dash to where it would not slide off and broke down the antenna by just removing the hamstick and disconnecting the coax. Then I put the yellow mount with the radials still attached in the truck bed ever so carefully and rolled the coax into the back seat and I was off. This made park changes really fast since I was sticking with 20 meters for this trip as I had good confidence that I could get the activations with just that band pretty quickly.

The next stop was the Zahnd WMA, which to be honest, I had never heard of till I started looking at doing a Rover. It is literally next to the road so it was in and out with a cleared little pileup and on I went. Below is what the parking area at the WMA looks like, it is actually really nice for a WMA parking lot. I had the place to myself since nothing is in season right now. Something else of note is that when I was working the early parks, I would cross 10 QSOs and then once I worked all the callers, I would go QRT and move, but once I got K-0716 activated I started getting comfortable with achieving the goal and would call CQ longer. For now though, as you can see below, 10 contacts (and just a few more) and I was off to the next location.

So the next location was about 10 miles down the road. I have activated Otting WMA before so I knew what to expect when I got here. The parking are is also right by the highway (which is why I chose this route to be honest) so access time is minimal.

You will notice I back into the parking location as much as possible to get the antenna out of the way so people and pets do not wander into it while I am transmitting.

Deploying the system involves, backing into a location to get my antenna out of the way and then opening the bed cover, installing the yellow antenna mount, laying the two radials out, then screwing in the radiator. Next I open the rear truck door, grab the coax and plug it into the antenna mount. A couple minutes arranging the cab, while listening to the band for an opening then I spot myself on the website and were off to the races. Below is the info kiosk at Otting, all these WMAs seem to have one now which is nice so I can see if there is a managed hunt or what.

Something else I like about the rover idea is there is a lot of driving in the country here. I passed through the town of Menlo GA between parks 3&4 and stopped to grab a couple of photographs. Some with my camera and some with my phone. Small town America is cool…

So for my next stop, I went to the Chickamauga national military Park, which is K-0716 and set up in the parking lot of what is known as the “tower” by the locals. It is actually known as Wilder tower and is a really common attraction in the park.

I backed into the space, even though they are angled in such a way as to promote pulling into them so this took a minute, but that allowed me to spread my radials in the grass strip between the parking space and the road. I have found that getting the radials out of the way of other people so they don’t trip over them is critical and backing into the parking spaces normally allows this. Another thing of note is do not transmit when there are people that can touch the radials as even at QRP power levels, there is enough RF energy on the radials to shock someone ever so slightly so the smart thing to do is not transmit while people are around your antenna. I had to be very mindful of the other people in the park while I did this particular activation, as I did not set up in my usual spot where there are very few people. In hindsight, I should have just used the usual spot as it is out of the way, and most people do not ever bother going there. Another thing to note is that by this point in the trip, I had gotten good at setting up and breaking down the antenna and radio to move to the next park. I knew exactly what I needed to do to get the radio in a position to where I could just set it out of the way and move to the next location without having to do a bunch of unnecessary, connecting and reconnecting of wires.

Once I got to this park, I realized how much time I still had and I decided to work contacts for a little longer here. I still continued to use 20 meters only because I did not want to get too comfortable with band changes and getting out additional equipment until I got to the fifth park. This park was actually fairly busy with people coming to see the tower, jogging and walking their dogs. Seeing this helped me to decide to keep the extra gear put away as well and figured I would play with the other bands once I got to the last park. I also knew the area at the last park pretty well and knew I would not have to worry about kids and pets getting into my antenna there.

As you can see though, I had a good run of a little pileup and it took me about 35 minutes to clear it. Once it was clear and I took a call from Teresa to sort out some shop problems, I was off to the last park of the day, K-2933. This has been one of my easy parks that if I am in the north east portion of Chattanooga that I can get to and have a nice quiet activation. so I go by there every month or so. I will probably get my repeat offender award for it at some point this summer.

Here is the storage tube I put together out of 2” PVC pipe to keep my growing ham-stick collection from getting damaged when not in use. It was cheap and I didn’t even glue it together, just friction. It fits diagonally in the truck bed with almost not play so it doesn’t roll around at all. Currently I only have 4 ham-sticks in it so I have plenty of room. You can also see the spare radials for the other bands I used here today laying on the ground for band changes. Like a genius, I tuned each band with out the radials for the other bands on the base and to prevent me from having any sort of problems arising from tuned stuff in the area, I just used them like I tuned them. Of course this worked beautifully well, but it did add a little more work. I am going to make the antenna mount to where I can install four ham-sticks at once and since they have such great out of band rejections, the RF for each band should find the right antenna without having to change them out. I just need to put the whole thing together and tune it first.

Mu impromptu sunshade for the Icom IC-705 worked really well.

Another surprise for this trip was that I pressed the Icom IC-705 into service as I have not used it in a while and wanted to play with it some today. I had also brought the Elecraft K1, but just as backup incase the other two radios failed on me…lol. The IC-705 is touch screen technology so it is easy to do all sorts of things like band changes and sending from memory when calling CQ. Plus it has a built in speaker which is nice when there isn’t a lot of noise in the area. Headphones are great when I am alone, but it is hard to explain to a passerby what I am doing if they can not hear the radio too. This is one of the only oughts I have with the Penntek TR-35. It has no internal speaker…

Here is your free tip of the day, most of you probably already know this, but some of you may not. Use colored phasing tape to color code your antenna and matching radials so you know which radials go with each ham-stick or what ever antenna you decide to use. This makes putting the right kit together a simple task instead of frustrating when the SWR is acting strange because you used the wrong radials with the vertical that you have on the mount.

Now as you can see below, I started on 30 meters. I ran into a problem here though, there was some sort of broadband QRM that was spaced in intervals across the whole band space. I finally found that 10.116mhz was fairly quiet and started calling. I got 4 answers before giving up to the QRM and moving to 20 meters where I had a great time free of this pesky QRM that was down on 30 meters. After a solid run of 18 contacts on 20 meters I figured I would give 17 meters a shot before calling it a day. I had somewhere I needed to be later so I had to pack it up by 19:00 UTC. Anyway, I do the band change to 17 meters and start calling. You can see in the log that it took me about 5 minutes to do the band change and get back on the air. This is why I laid all the stuff out like I did. I wanted to make it easy to do till I can get the multi antenna system done. Well I netted another 18 QSOs on 17 before having to go QRT for the day. Total for this park FOURTY in 1 hour and 20 minutes (80 minutes). I could have probably gotten more if I had not messed with the WARC bands and just stuck to 20 meters as it was going crazy. BUT where is the fun in that? I had the activation so why not play on the other bands a little since I have the stuff?

If you see your call in the log and want to swap QSL cards, I only do paper cards and I will respond to all that I get. This was a load of fun and I think next time I will take a helper to help with logging and band changes and stuff, I went solo today and it was … quiet… at times. This makes for a great times if you don’t mind the solitude, but for some it might be a problem. I was busy all day so it didn’t bother me in the slightest. Just be aware of that.

So till next time, get your radio out!!!

A bunch of POTA activating in one day.

The sunspots were being nice to me today with my tiny ham radio and CW key…

The amateur radio of choice for today is the Penntek TR-35

Well I went to a bunch of parks today. It wasn’t planned, I just found myself in the right areas to be able to get to several parks in one day, so Carpe Diem! I found out later that I only needed two more to get a rover award so now it is on! The first level is 5 parks in one day. The goals go up from there to insane numbers of parks. I am convinced that at the peak levels, you have to operate mobile with vehicle mounted antennas. You just dont have time to activate 20, 25 or even 30 parks in a single day otherwise. It takes me ten minutes to get into the park, stopped and just get the antenna deployed then just as much time to break it down. So all that wasted time has to be eliminated. It would have to be a military style operation to be honest, having someone log for you too if you wanted it to go easily, but 5 or ten should be easy enough…right?

Back to what happened today…

I first made a short stop at my local haunt of K-2169 Cloudland canyon state park. Then I spent the mid day with the family and doing some chores. I wanted to get in an activation before I went to father/daughter brunch and was able to do that with ease. Unfortunately, I had to leave the activation before I wanted to, as there was a decent pile up going and I really don’t like to leave anyone hanging…but the kiddo was waiting for me so off I went.

This parking lot is literally at the bottom of the mountain.

I ended up at the foot of the mountain this time as it saved me a solid 20 minutes of driving by not going to the top of the mountain. This allowed me to stay on the air a little longer and added about 15 QSOs to the log because of it. Signals were strong even with the mountain right beside me. I was honestly impressed with how strong a lot of the ops were on my ham-stick. I used 20 meters as I wanted to be sure to secure the activation in the time frame I had, which was only about 30 minutes from the time I powered the radio on. This is why I didn’t goto the top of the mountain, the drive up there would have eaten all the operating time. As you can see though, the inbound signals were strong and I got a lot of good reports back as well. This location isn’t all that bad to be honest as long as there is room to deploy the counterpoise wires.

Later in the day, after brunch with Sierra (KK4RJW), I was near Harrison bay state park so I figured I would try to get another activation before the day drew to a close. (I was also working on a youtube video for my photography channel and wanted somewhere fairly quiet to record it and this sounded like a good spot). During the weekdays these parks are normally ghost towns and I usually have free reign of the place. This is why I like them for recording video content.

The park is home to a really nice marina and boat ramp and I chose to setup in the far corner of the parking lot where the boat trailers are parked. There was plenty of room here for my radials so no one even gave me a second look. I opted for the 17 meter band as I wanted to see what I could do with it and I wasn’t under the time constraints like I was earlier in the day.

I noticed a lot of these trees were blooming at this time too. I think these are called red bud trees, but to be honest, I am not sure. They sure were pretty though. So I thought I would grab a quick photo and add it to the blog for color.

Since I was wanting to record the footage for my video, I stopped calling CQ after I got 15 QSOs in the log. I always like to go over by a couple so that if I find out I copied a bad callsign, I still have enough for an activation. This one went a little slower since I did the whole thing on 17 meters and didn’t bother to change bands during the activation. You see, right now, to change bands involves me going to the rear of the truck and changing whip antennas as well as the counterpoise wires as these are all tuned independently. I will eventually build the mount that holds 2 or three of these at once (maybe all four) and I will retune the radials to work with all of it set up at once. I checked the ham-sticks and they have unreal selectivity with there being only one resonant null on the nanoVNA across the whole spectrum up to 30mhz. There aren’t even any harmonic bands, just the one they are tuned for.

Well on the way back from Harrison bay, I drove right past Booker T Washington state park…so I said to myself “Self, we should activate this one too” and with that I swung the truck around and went back to get 10 more contacts with the TR-35 and my newly minted ham-stick collection. Turns out this was a good call as you guys came in the clutch! Wow! FOURTY QSOs in short order!

I got there and setup near the playground on top of the hill. These are old campsite spaces that the park no longer uses for camping. The parking spaces are still paved and the grill is still at most of them so people still use the sites to do cookouts now. This in turn makes them perfect POTA parking spots as I spoke with the park ranger and he said it was perfectly fine to setup in these spaces and play radio anytime the park is open. As you can see below, it makes for a great location and there is plenty of room for the radials if I back into the space.

The radials dwarf the ham-stick antenna but the sure do work well.

This time I chose the 30 meter band to start with and then changed over to the 20 meter band to finish up as I was getting a lot of calls from this location. Doing the band change is not really that bad but it is slow enough to make you not want to do it a lot. I think the multi mount for the antennas will make this a great all day rig where I will setup for several hours and want all four bands.

Signals at Booker T Washington park were strong today!

I have figured out how to get the radio to rest on the dashboard of the truck so that I can free up more space on the armrest for the logbook. If fits here perfectly and allows me to connect the headphones and key with just the right amount of room on the wires. It also gets the VFO knob out of the way so I don’t bump it and push myself off of frequency (which I have done in the past). It is still in a location that I can access easily though for speed changes, memory access and such.

Below is my “POTA tote” that I was gifted at Christmas last December. It holds all my POTA stuff and a bunch of extra things too. The tote almost has two complete rigs in it at this point there is so much redundant gear in it. But it is convenient and I can just grab it and goto a park as the ham-sticks live in the truck full time now in a pvc storage tube I made for them (see photo below). I keep them, the trailer hitch mount and the radials all in the back of the truck together so they are ready to deploy when I arrive on location. Easy.

After a good little run of QSOs on 30 then another one on 20 meters, I cleared the pile up and called QRT to go find the wife and have some supper. Little did I know at the time, but I was over half way to a Rover accomplishment. I now know that I only needed two more parks to get the first level award in that and I already know which two I am going to use… LOL So next time I will get my 5 in one day.

Thanks for following along on my little CW adventure in ham radio. 72 WK4DS

A “quickie” POTA activation…lol

What happens when you plan to do something “right quick”? That’s right, it doesn’t happen like that at all. Haha.

I had about an hour of free time today between activities with the XYL and K-2169 was … technically… on the way to meet her, so LET’S POTA!

K-2169 Cloudland Canyon State Park is a 15 minute drive from my house so if you look at that park on the POTA site, you will find I go there a lot. Today, I wanted to get setup quicker than normal, which means I opted for the lower parking lot. This parking area is next to the canyon proper and is where I like to setup my wire antennas in the warmer months.

The lower lot was pretty sparse so I was able to get in a corner, out of the way, which also afforded me the ability to use the side of the truck to shade me from the setting sun. I grabbed a camp chair out of the back of the truck, threw up the 17m hamstick and got on the air. The truck tire made the perfect “table” for the Penntek TR-35 QRP radio too. I used the battery to tie down the coax so it would not slide off the truck and pile up on me (like it did right before I sat the battery on it) and made the station nice and tidy.

I started on 17m calling CQ as I heard quite a few stations having QSOs. After calling CQ for a few minutes I got an answer from NA7C in Utah and then a little later KJ7DT came in strong as well from Idaho. But then I called for a long time with nothing coming back so I decided to change bands and see if I could finish up on 20 meters.

Once on 20 meters, I found a clear spot and started calling CQ again. Just a moment later KJ7DT came back again! This time even stronger!!! Idaho was booming into Georgia today. That gave me hope! So I worked Paul leisurely, as he was the only one to answer my call, and then cleared him to find myself in a ginormous pileup! Where did everybody come from!?!?!? Good Lord I had trouble pulling out single stations. I have never really had to deal with a legit pileup before. Oh sure, I have had 4 or 5 stations call at once but this sounded like 20 or 30! I start plucking out callsigns and in the process of the next 38 minutes I put 38 QSOs in the log. That has to be some sort of a record for me!

Some items of note from today that I found interesting were that I worked KJ7DT back to back on two bands without coordinating that with him, then I ended up working three DX stations today with one of those being DL1AX in Germany, another was VO1SW in Canada and finally CU3DI in the Azores! I even worked a Park to Park for a 2Fer! Sweet! Speaking of sweet, the dogwood trees are in full bloom as well making for a beautiful scene on top of a 40 QSO run on my tiny little QRP radio in just under an hour and that includes an antenna change!

Check out the QSO map I got from the HAMRS app showing the spread. Side note about HAMRS, if the op isn’t found in the Hamdb database, then search them on QRZ and get their grid square and add it to the QSO info if you want them to show up on the QSO map. This is how I get non-POTA ops to show up.

Here is the USA map without the tags so you can see the radiation dispersion of my 5 watts and a hamstick antenna.

I think that I could have most likely worked most of these ops today with SSB and it would have been successful. 20 meters was that strong today. This comes on the heels of the previous evening where I worked Ian in New Zealand on 10 meters via greyline! This has been a good 24 hours for radio! Confirmed via QRZ in real time no less! I am sending him a real QSL card anyway but that always gets me excited. It isn’t everyday that I can even hear New Zealand on 10 meters much less them hear me.

Here is another tidbit about me. If at all possible, I will always clear the pileup before going QRT as I know some of them are needing my park for one of their goals and if I can help them with their goal, whatever it might be, I want to do that. I had not initially planned on staying for an hour but it was so rewarding that I just couldn’t power down the rig. Lol

Today was a pleasant surprise and I look forward to more like it in the future.

72 and I hope to hear you on the radio!

Activating an Off-road Vehicle Area is not always a great idea.

Sometimes things look better on paper…

But in execution, they are not a great ideas.

This is the story of me (WK4DS) at K-5493 Franklin-Marion State Forest.

On my way over to the park, I passed through South Pittsburg, Tennessee to shoot a little photography first since it was on the way to the top of the mountain to do an activation…

When I arrived at the park location I liked, it was perfect weather and quiet and as you see from the photo, I had the place all to myself. Well, that changed in about 15 minutes from the time I took this photo. You see, this “park” on the POTA map is actually a state forest with OHV trails on it. I parked in a clearing that is about 100 yards off of the paved road and is next to an old forest service fire tower. The luxury to this site is that it is literally on top of the mountain and 100 yards of gravel road from the pavement. So I have a great elevation profile because of that and easy access to a good site.

This is an old forest service fire tower. It was on the other side of the clearing and is so old that it had trees growing through the framework and the building at the top had no floor in it anymore. I remember these in use as a kid, but at some point they stopped using them, and from the looks of this one, it was probably in the 90s. There was another feature that I noticed as well… Have a look at the photo below and take a guess what made all those holes…

I cant go up there and see, but I am pretty certain those are bullet holes. That is one thing that “rednecks” are good for, shooting things like this… I don’t know where this mindset comes from, but they tend to do things like this. It is unfortunate too as this is basically destroying relics from our local history for simple entertainment.

Another thing that I ran into on this trip was that the little adapter shown below that goes on my headphones has failed. It was causing some heavy shorting issues and I ended up figuring out that if I spun it to the right position it would not cause a problem, but spin it just a little and it would make terrible feedback. I didn’t have a spare either so I ended up using it and just being super careful with it…Always have a spare is the lesson here.

In the photo below you can see what I am talking about when I say there were ATVs going by while I was operating. Lots of ATVs would pass through at times, like 4 to 6 in a group at once. These vehicles also don’t have great mufflers either so it would be hard to hear while they were going by…

Since it was nice weather, I wanted to use the truck bed cover for my operating position and because of this, I was right next to the antenna. Also if you will notice, there was a couple more hamstick antennas this time. I picked up a 17m, 30m, and a 40m Shark brand hamsticks from Chatt Radio and spent the morning before the activation today tuning the 17 and 40m antennas. I didn’t do the 30m unit yet because I ran out of time as I wanted to try an activation today and I still had to make all the parts for the radials for the 30m antenna from scratch… Once I got the 17m radials made and tuned and then cobbled my 40m hamstick radials together so it would work (I think I need to revisit this one at some point and make better radials for it), I was off to the races! This design of antenna and mount work extremely well for their size.

Today’s weapon of choice is the Penntek TR-35. This radio has everything you need and nothing you don’t. It is just a great little CW rig that is simple to use and works really well.

This is a close up of my 17meter radial tie down, that I dubbed “Gen 2”, ground weight design. I can remove the weight easily from this plastic connection plate and use it on a different radial if I wanted to change bands or something like that. This worked really well and was easy to setup and tear down too. My old design coupled the weight to the radial making it a dedicated weight, which is simpler to make, but not as versatile to use as the weight is part of the radial.

Below is the complete antenna kit as of today. This doesn’t show the mounting bracket that I made to install these on, you know the big yellow one, right? But here are the radials and antennas that I currently have tuned and are ready to get on the air. Once I get time to work on the 30m antenna, I will add it to the stable. The ham-stick is a very viable option for the QRP POTA op. I used these today to get the contacts below and you can see that the signal reports show it works just fine. If you have one, this is something that I suggest you try to use. They need the radials though to get the best performance. I have found that is important. Supposedly they are designed to not need them, using the coax as the counterpoise but they just get out so much better with them tuned to the band with a proper counterpoise.

If you will notice, I make lots of notes as I go in my log, but I had a great day on all three bands. It was cool to get some contacts on 17 and 40 meters today, but if you will notice, all the magic happens on 20 meters… That is where the bulk of my contacts happened today. I also was able to work the same ops on multiple bands which is kind of cool.

So even if you run into problems with the location like I did, just get the radio out anyway as it just might be the day you put over 70 QSOs in the log! So till next week, get that radio out and throw a wire up into a tree!!!

Dalton Hamfest 2023 for a Ten Tec radio junkie…

Well, it is that time of year again. The Dalton Hamfest is one of our bigger local events and this year did not disappoint. Below is a Omni 6+ with matching speaker power supply (radio in the bottom of the stack) just like the one I use in my ham shack at home. This particular radio was found outside in the boneyard of all places. This is a wonderful radio that would work really well for anyone wanting to get on HF. It is especially good for CW, the receiver is just buttery smooth and wonderfully sensitive…I could go on about this radio for a long time, but suffice it to say, if your into CW and vintage radios, this one is hard to beat. It was basically the pinnacle of CW rigs in my opinion.

Aside from the usual vendors where you can get any number of new radios, antennas or other widgets associated with Amateur Radio, it has become something of a quest for me and Trey (KG4WBI) to find all of the Ten Tec gear we can find and photo document it without buying it! LOL we ALMOST came home with that Triton…(just take a gander at it below) it was in great condition and worked beautifully…

This year netted a incredible pile of photos that really impressed me when I started looking back through them. You see, while you’re walking around, you don’t notice that you have seen so many pieces of equipment until you start looking at the photos you’ve captured of them.

A prime example of this is the fact that we found two of the same kind of antenna tuner. Yet one looks like it was in a smokers ham shack and the other was not. I am pretty sure this is actually the case too as I have never known Ten Tec to do a run of gold trimmed radios or accessories.

Something that I did notice was the wide variety of Ten Tec radios that we’re at the hamfest this time, everything ranging from an old Triton and Argosy (pictured above with the matching power supply) all the way up to an Omni 7! By the way, that Omni 7 also has 6 meters… 😂 Once I added the Collins filters to my Omni 7 it is one of my favorite radios of all time. It works surprisingly well with just the stock filter but the selectivity just gets unreal with the additional 500hz and 300hz mechanical filters made by Collins.

One particular radio of interest that I have always been intrigued by, but have never really thought about buying is the Ten Tec Scout. This radio is unique in that it is a small, portable radio with a fairly powerful transmitter. I think it is 50 watts of transmitter power and to change bands, you replace the cartridge on the front of the radio with a different band module. This allows the radio to remain fairly small and still cover all the HF bands. This is a really forward thinking idea and Ten Tec is renowned for this. The Jupiter radio is a perfect example of their forward thinking, it laid the ground work for the whole Flex line of radios.

To have a whole set of these band modules is fairly hard to do and this gentleman, at the ham fest, had all of them except for one. He was missing the 30 meter module only from what I could see. This was a really impressive kit that he had and it was also in a nice pelican case and the price was really reasonable. This would make for a really awesome POTA rig or even a field day rig.

I guess it just proves that there is more out there available than you think when you just start adding it all up. Since I was just casually snapping cell phone photos as we walked around the ham first, I never really look at the camera roll until we were leaving, and that is when I realise we had seen so many different radios by just this one manufacturer, who is actually out of business at this point. There were even more radios from the typical Icom, Yeasu and Kenwood factions that were everywhere. There was plenty of equipment to choose from is my point.

It was nice to see that someone could still most likely find an obscure, vintage radio that they had been looking for, pretty easily, and to be honest there was a ton of Drake, Hammarlund and Collins radios as well. (That Drake TR7 really had me… I love the color scheme they chose especially well)

I have to give an honorable mention to another radio that is near to me that I have yet to own, and that is the Elecraft K2. There was a 10 watt version of this radio also for sale that day, and I was very VERY tempted to take it home with me…

But explaining to Teresa, why I brought another radio home was not something that I was looking forward to doing, so I left it sitting on the table and maybe cried a little…dont tell anyone… haha.

All was not lost though, as we did bring a radio home between the two of us. It turned out that Trey acquired a 2m Ten Tec HT that has been made out of pure hens teeth. He is actually working towards getting it operational again. He put it on a bench power supply and it did power up but it needs a few little things repaired on it. Currently it does not have a battery but he is looking for a battery to rebuild to put back on it. So if you know of someone that has a battery, even if it is trashed, please let me know as we can rebuild it, as long as it is complete.

Going to a hamfest for me, is more about community than equipment these days. I did grab a few ham stick antennas for my QRP radios when I do POTA activations, but other than that I did not get anything substantial at all. What I did most of the time instead was chat with friends, (whom all I had seen the night before at the club meeting LOL) and made a few more while at the tables talking about the really cool radios we found.

All in all, we had a great time today and if you have never been to a ham fest, I recommend you go to one just to see the spectacle of it. The bigger the better. Until next time, get your radio out!!!

POTA that turns out really good for QRP radio!

Well, today was an unusual day, so lets set the stage… First we go to church and when we get home, there really isn’t much to do so I decide to run over to my local park and get an activation in during the afternoon. This turns out to be the beginning of an adventure for the next few hours that almost DIDN’T happen!

My N6ARA Tiny Paddle got some use today.

You see it all started at home when I was testing a power cord for my TR-35 radio. I wanted to add a cord to the POTA tote that I was assembling and I found one that looked like a good candidate. So I get the radio out and plug it into my shack power supply to see if the QRP rig would power up properly and it did. It worked perfectly. So then I put the cord in the kit as a permeant addition to the POTA tote. Once this test was complete I got my N6ARA paddle out of the other bag and added it to the kit and then I was off to the park.

There was at least twenty groups on the course this big! So many people were there playing disc golf!

When I arrived at the park, I was in for a surprise! The parking lot was almost full of cars! This parking lot is normally reserved for me and me alone! LOL! I am used to seeing maybe 6 cars on one end of the lot where the beginning of the disc golf course is located but that is all! There were disc golfers everywhere for some sort of tournament. I was worried I would not be able to setup, but as lady luck was on my side, I found a good spot and got the antenna in place.

This is where things take a turn for the worse. I get the antenna setup and hop in the truck to layout the radio gear and find I forgot the actual radio. I had all the support equipment but no radio. It seems when I tested the power cord that I failed to put the actual radio in the POTA tote… I felt totally defeated to be honest and almost just broke it down and was about to give up. So I thought I would call the wife to see if she would help out and she agreed to meet me half way in Trenton and bring it to me. So I laid the antenna assembly on the ground and ran down to Trenton to grab the radio, hoping all along that no one would bother the antenna laying in the grass beside the parking lot.

This saved the activation to be quite honest about it. It added about 15 minutes or so to the time table to drive down to Trenton and back and fortunately, no one bothered the antenna (seems my worries about disc golfers being curious were unfounded) and I was able to get on the air after all.

This is when I found the next problem… There was some sort of contest this weekend on CW that I was unaware of and the band was super crowded. I was starting to think I couldn’t find an open frequency when I landed on 14.068 mhz and no one was there! At least no one was near enough to me for me to hear them… So I waited a few minutes and listen and nothing. I call QRL a couple of times and then get going. This is noted by the “on air” start time and the actual time I started making contacts. I normally don’t wait a full ten minutes, but this time is was probably 6 or 7 minutes and then it took a few calls to get QSOs coming in… I do other admin stuff while I am listening as well, such as getting my POTA spot on the website and positioning my gear in the truck for max comfort and such.

Another reason I didn’t just move to a WARC band was that I only have a hamstick for 20 meters at this time. I plan to pick up a couple more at the Dalton Hamfest in a couple of weeks from the time of writing this blog… I hope they have some! Below you can see the “POTA tote” and my rig for the day, the Penntek TR-35. This is truly one of my favorite radios and would have been the radio I carried to Hawaii had I been able to confirm that my tuned EFHW antennas would stay in tune in varied setups due to terrain… I plan to test this once I get back from the trip, but we leave in the morning as of this writing and I didn’t have time to test the idea properly prior to leaving.

The log sheet speaks for itself. There is a number of Canadian hams this time as well as the one to Italy as well. I couldn’t believe how many calls I got in such a short time. This was an amazing activation for me and to think, I almost gave up when I failed to bring the radio… Then as fast as it started, it abruptly stopped. When the last entry was written down I called CQ probably 5 more times with no replies so I called QRT and packed up. What an afternoon!!! This just goes to show that 5 watts has the magic if you get on the right band at the right time!

So if your thinking that you wont have a good time with your radio and there is no sense in even setting up, just remember this blog post and how I even forgot the darned radio!!! So get out there and warm up that atmosphere!!!

Trouble activating K-1878 Hillsborough River State Park in Florida!

I ran into some problems with the area I was in but worked through them and even grabbed a photo of some local wildlife. So let’s get started…

Finally!!! I GOT MY FOURTH STATE!!! Lol. We had went to Tampa Florida for a few weeks to escape the winter in North Georgia and so I grabbed a couple of radios for some POTA fun.

First, a little about the park. This park was easy to get to and it is a big loop through the wilderness area with pull offs as you go around. There are hiking trails, camping areas as well as playgrounds and other facilities on site. They even have a small outfitters store in the center of the park. All of the parking spaces are pull in angled from the road as you see in the photos throughout the entire park except for the very first one where there is a small visitor area with a historical reference section.

The park is beautiful, and basically shows you what a wild Florida would look like if it was not covered in houses and strip malls. The park does require a fee to access it and you pay when you pull into the entrance.

There is a guard shack and they collect the fee there. I had several park employees travel by my setup while I was operating and no one gave it a second look. I believe this is because my set up is very low impact as the radials are held in place by weights, and the antenna is actually connected to my truck and freestanding.

This parking created a small challenge for me as I tend to need to back into the spaces so that I can deploy my antenna ground system. My solution to this problem was to drive around the Park until I found a section of the parking lot that was vacant of cars. Once I found a vacant parking lot, I could pretty much choose where I wanted to put my truck, so I put it in the furthest corner from any infrastructure which typically lends itself to not ever being in anyone’s way.

As a sidenote, once I had finished my activation, I realized that there was a observer watching from a nearby tree. I am pretty certain this is a red shouldered hawk and it’s very beautiful. There were several of them in the park and I happened to see this one fly down and catch something small on the ground and then flew up to this tree branch in a nearby small tree, where he sat (or she I’m not sure which) until I was able to get my camera and walk over there and take a photo of it.

Onto the Amateur Radio portion of this adventure. Once I found a spot to get out of the way, and that was far from any structures that I could find, I parked in the corner of the parking lot, deployed my antenna system and got out my ICOM IC-705 radio. This is where the trouble began, I learned quickly that there was some sort of interference that was washing over the entire CW portion of the 20 m band. I did not even bother to check the other bands as the only antenna I deployed today was a 20m hamstick.

I jokingly considered it to be similar to the “Russian woodpecker” of days of yore as it sounded like that every few kC. I am pretty sure it is the radar installation at the Zephyrhills municipal Airport as I was in the direct flight path to the runway. My antenna being a vertically oriented radial, is a very noisy antenna anyway so I am leaning towards this deduction to the problem. I have heard RF hash from other devices, and none of them have ever sounded like this. It literally sounded like a woodpecker.

Combine that with the fact that I was only 7 miles distant from the airport. I also had aircraft going overhead occasionally as well. This is what clued me in that the airport was somewhere nearby, and that I was in the flight path, I kept hearing airplanes lol.

I tried a couple of different things to see if the problem would go away and figured out really quick that it was not with my system, and that I could only work with what was there. I even turned down the RF gain in an attempt to hide the noise from me, but that didn’t really help since I would be transmitting sometimes on top of this noise, and that would make people not able to hear me calling CQ. What I wound up doing was looking for a section of the band between the noise spots and setting up in those areas. I finally found a couple near the QRP calling frequency and started calling CQ.

This worked really well as I was able to quickly get 20 QSOs in the log in about 30 minutes. I even got a few of the guys, that I normally get back in Georgia, in the log as well, such as K9IS for instance.

The set up today consisted of the 20m hamstick with radials piped into the truck to the 705 direct with no tuner. The power from the truck powering the radio out of the cigarette lighter port and I was using my little portable travel key that I bought off eBay and that was it, very simple.

So, I guess the moral of the story is don’t give up, even if you have something like the Russian woodpecker beating down your receiver. Just find a spot that is as clear as you can get it and try from there, you never know what you will find.

Thanks and 72
