A couple of quick activations testing the antennas

The past couple of days have been busy and there was still time for a couple of quick activations along the way.

First stop is the Estelle Trailhead on Crockford Pigeon Mtn WMA (K-3742) over in LaFayette GA while coming home from visiting with my mom. This is actually a new park for me even though it is only 15 miles from home by road… I dont know why, but I have never activated it for some reason. The Estelle parking area is fully within the WMA boundary so it was a simple matter to pull in, get parked out of the road and setup a radio in the shade for a little while. Today saw the Ten Tec Argonaut 5 again as this radio was the one in the truck at the time. It is also one of my favorite HF radios at this point. It only lacks two things to be the perfect radio, an SWR meter and an internal antenna tuner…but I digress.

I said that I setup in the shade, but there really wasn’t much to start with…lol. I did get lucky and a nice cloud moved in after a few minutes and helped keep things cool. I don’t like to let my radios just sit and cook in the sun if I can help it and will go to fairly great lengths to prevent them from getting hot. This is what you see here. The shade was just wide enough to protect most of the radio from direct sun so it didn’t get very hot before the clouds moved in. On top of that the tool bag is shading my battery in this photo too, I didn’t want it to get too hot either…haha.

I started on 15 meters today as I finally have a 15 meter capable radio and antenna too! Well the RBN showed 29dB for me! That is crazy good for someone with 15 watts under their belt into “7” land. But try as I may, there just wasnt that many hunters on 15 meters for some reason. I did get 3 QSOs in the log while on 15 meters so all was not lost. Then I moved down to 17 meters and did quite well there, picking up several more contacts. Then I finished out the activation on 20 meters which is my backup if I need to get my 10 for the activation. 20 never seems to let me down either as I can almost garuntee at least a few contacts there.

So after getting the activation, I wanted to experiment with the antenna system and see how it would work on the drive home. Turns out the 20 meter hamstick without radials has worse SWR than with them, going from 1.15:1 up to 1.7:1. Who would have guessed? LOL. This is not a real problem though as this is still well below what I consider useable SWR. As long as I can stay below 2.5:1 I will operate. That is the upper limit though and I will work on the antenna a good bit to get it down but if nothing helps and I have 2.5:1 SWR, I will try it. The radios can handle anything below 3:1 so I set my personal threshold below that… I know some people wont use their gear if isn’t almost perfectly 1:1, but I have come to realize that it isn’t so important and the signal reports speak for themselves.

On the drive home, I start hearing this REALLY strong signal booming in to the Argonaut 5. The above photo shows what the signal level coming into the radio was 20 over S9, and remember that the Argonaut 5 has a S meter that doesn’t like to give out good signal reports. So I start working on head copy on the drive and finally get that it is W1AW/0 in Colorado and he (or she) is working as a POTA park! So I do what any sane POTA hunter would do, I pull over at the New Salem Firehall and work them mobile! WK4DS/M got into their log!!! WooHoo!!! So at the bottom of the logbook page you will see where I logged the hunter contacts on this trip since I was not at a park when I made these contacts.

New Salem Firehall parking lot was empty and worked great for getting my hunter contact on the drive home.

As a side note, I finally made the hitch pin (shown below) for my antenna mount so I can use it for the rover program without having to pull it off the truck and stow it between parks. I am working on reducing the setup and breakdown time at each park as I am going to attempt a 10 park rove and this will take planning to make it happen. Things like this can add up on the rove to make it take too long since the drive time from one park to the next will be the biggest time eater of the day. So if I can find simple little things that I can do on each stop to save time, I can make the most of the activation.

I made the main pin that holds the mount, but I simply bought the little pin to lock it in place. Sometimes it is smarter to buy a part rather than spend the time to make it. The main pin was easy enough to make from scrap shafting material. but to make the keeper pin would have taken more than the 3$ it cost in time so I opted to simply buy it instead. To be honest, it would have probably been smarter to buy the main pin too, but I had a scrap piece of round and time available on the lathe so I just carved one out right quick rather than drive to the store to buy one. Another plus is that I could make it like I wanted which included adding the handle to the main side so it is easier to pull when breaking down the system. On top of the pin making, I also opted to add an extra set of holes to the antenna mount so that the pin can be left in for simple POTA activation days where I dont have to pull the pin to simply setup for a single park. This allows me to just stick the mount in the hitch and use it like I have been and take it down when done so I can stow it inside the truck bed when not in use.

The next park I went to a couple of days later is the Chickamauga National Military Park. K-0716. This park lies in two states, so today I opted to activate the Tennessee side of the park. This location is easy to access as it is literally on the side of the road. This is why I like this location and hate it at the same time. The location is called Eagles Nest and is part of the military park completely within the park boundary.

K-0716 presents me with a quandary. This “shack” position makes for a comfortable operating position but the road noise is really bad due to the proximity to the road… I have used headphones here before and that seems like the correct thing to do if I operate here much more. I am going to go ahead and get my repeat offender for activating this park. I am already half way to this award anyway so why not? Ha Ha… Another thing that surprises me is that there are some fairly large trucks to travel up this narrow and winding road to the top of the mountain. Like large d4livery trucks kind of large, I guess it is normal, but it just kind of caught me off guard to see such large trucks going by while I was there.

The radial situation is unique here too, since it is on the shoulder of the road, I have to put both radials on the same side of the truck. Whenever I do this, I always get out the nanoVNA to see what this has done to the SWR plot. As usual, it did affect it but not by much. I was surprised to see that on 15 meters it needed both radials to get a decent SWR before I was happy. So I get it setup, spot myself, start a log in HAMRS and start calling CQ. I finally net a couple of contacts on 15 meters, but there are not many hunters even though the band was open. It did have some fading, but it was fairly strong anyway and could easily support use, but people were not there. So I moved down to 17 meters. Once on 17 meters the RBN (Reverse Beacon Network) picked me up and showed the strongest signal report I have ever seen for one of my activations. 42dB is insane! I have never seen that and this was with 15 watts no less. So people MUST be on this band, right? Well no, it seems that all the people on HF were down on 20 meters having a grand old time without the few of us up on 17 meters. I added 4 more QSOs to the log with one being KJ7DT who followed me down the bands working me on all three on this day. To me this is awesome as it shows the propagation for all three bands was really good as he is in Idaho which is almost 1800 miles from me.

So I finally decide to join in on the fun on 20 meters and QSY down with what seemed like the rest of planet earth and secured the activation in short order. Getting Paul - KJ7DT a third time on this day and Keith WI0S twice! Both of these calls have appeared in my log on numerous occasions. These are some very prolific hunters and I just want to thank them for being there to hunt like they do. They are what make activating parks fun. With 13 calls in the log I officially had the activation so I packed up as it was getting close to lunch and the road noise made it very hard to hear as well and headed into Chattanooga to go have lunch with the girls.

The clip board has made a huge difference in operating ease for me. I can now not worry about the wind turning the pages and it gives me a hard surface to work from no matter where I am. This alone helps a ton. As seen here, I am able to lay the keyer and the key on it as well as log. If you still paper log this is a very handy addition to the POTA kit in my book. Yes, I still paper log. I have had too many computers where they crash unexpectant and you have to reboot the machine and wait for it to get back up and running to trust it with my only log of an activation. The paper notebook gives me a durable backup to my phone logbook that I run at the same time.

Side note about how I log… I will run HAMRS in parallel to my paper logs and if the activation is going kinda slow, I can log both at once and keep the electronic log caught up in real time. This is a recent thing brought on by me wanting to not have to set aside time at home just to transcribe the log so I can submit it online. I found that a lot of my activations are slow enough to permit time to log the QSOs while I work the activation and not have to do it at home. So if things speed up and I cant log both the paper and electronic, then I always default to paper and the battery never goes dead in paper logs nor does the app crash… Then when things slow down, I will let the keyer send CQs and I will catch up the electronic log while I am calling so I don’t waste that time just sitting there waiting on an answer. This works really well and I can normally email the log from the park before I leave so when I get home I can simply upload them to the POTA site since it wont let me upload from my phone yet…

Here is something else that a lot of people that don’t do field ops have no idea about. A carrier with a bunch of backup equipment is a must. Everything in this bag has been used on an activation in the last few months in one way or the other. Notice there is power cords and spare coax and three pens are visible on the side, this is something that you quickly learn, things break, pens dry out, you run out of paper, all of this is things you have to prepare for before going to the park and the only way you learn this is from doing it. I can preach to the ends of time but until you have to end your activation because your coax connector came off or the center conductor broke on the coax or your antenna mount breaks, you wont prepare for it as a contingency. That is just how it is…Another really handy tool to have is a Leatherman multitool of some kind, brand isn’t important, what matters is that you have one, I don’t know how many times I have used mine to save the activation some how. Totally worth the price of admission in my book.

QSO maps are awesome, I have KJ7DT in the log on all three bands today so his one pin is actually three. Just like I have WI0S in the log twice so his pin represents two contacts. This is neat to see though as you get a visual idea of what the bands were like on this day. If I studied space weather more then I would be able to corelate the data so that it would be more meaningful, but like this it really doesn’t tell much other than skip distance for the bands I used. That is about it but it is still fun to look at them nonetheless.

So this is what it looks like to activate two parks on two different days and how the setups vary for each one based on the conditions for each location. Next time I will carry headphones for the one by the road so I can hear better. Till then, get your radio out and make some contacts with it!!!!

A super cold (for me) POTA CW ham radio activation

Well today was super cold to me after spending a month in central Florida. It was 29 degrees and the wind was howling at park K-2169 (Cloudland Canyon) back in NW Georgia!!! I didn’t let that stop the ham radio bug in me from getting out in the cold and activating a POTA site!

I thought to grab a selfie to remind me of how dumb I was to get out in this cold weather so maybe I would think better of it in the future…probably not, but it was worth a try. You can see how I have the door open on the truck, I was using it for a wind break to keep the crazy gusting winds from freezing me solid with wind chill. That is why I logged in the back seat instead of on top of the bed cover which is my preferred location if I am using the truck for ops.

The weapon of choice today? The Elecraft K1 (4 band version with 40, 30, 20, &17) My particular machine also has the internal antenna tuner as well. I guess you could say it has everything other than the internal battery. This is my second copy of this tiny machine, but I have had a long love affair with these little radios. I sold the first one and literally missed it the day i shipped it off. It only took me a few years to find another one like the first one and get my little grubby paws on it…this time for keeps. Of all my QRP rigs, I place this one VERY near the top.

In the photo below we see the Elecraft K1 as seen from the top, I have placed the BNC to screw lug device on the antenna output of the radio and connected the antenna and counter poise directly to the radio with no feedline at all. I did this on purpose to test the system like this for a upcoming project I want to use this radio for in this configuration. This allows me to see how effective it is with a very minimalist rigging. I am wanting the whole thing to be as minimal as possible and still reach the west coast if possible. You see, I have a week in Hawaii and by the time you read this, I should have been there and returned with at least one activation from the Big Island of Hawaii under my belt… only time with tell.

The below photo shows how I took the tension off of the radio with the wire antenna once I strung it up into the tree next to the truck. This is a modified version of a knot we used in the Boyscouts called a taught line hitch. It works REALLY well on tent ropes for tensioning them to the stakes, it also works really well for tying a small cord to the antenna wire to make it to where you can tie it off to something near the radio as well. If you look above at the photo of the front of the radio, you can see the other end of the cord tied to the top cover ring on my bed cover. This end of the cord is tied to the truck with a bowline knot so it can be undone easily when I finish the activation.

Below is the only photo I have ever been able to get of the wire itself and it actually show up in the photo well enough to be meaningful. I threw a line up into the tree and pulled this wire up about 25 feet off the ground with the throw line and it worked really well. I know this is really low for a wire this long, but I was frozen and in a hurry and didnt want to rethrow the line to try and get it higher in the tree. So I used what I had.

OK, so here is the part where I talk about the antenna that I used. This antenna is simply a random wire right at 41 feet long and the counter poise is 13’ long. These are technically not supposed to be resonant on any of the 4 bands I have in this radio, but as it turned out today, the antenna was almost perfect on the 40 meter band with it arranged near the truck body. (it was reacting capacitively with the truck as I could change the SWR by literally moving the counter poise closer or further from the truck. It would also change the resonance of the antenna too, so I used the internal tuner to be safe) I used this to my advantage and worked quite a few 40 meter contacts today. I also cut counter poise wires for the other three bands and plan to set them up and see what the nanoVNA says about them when I have time. Something else I have learned to do over time is to put the wire length flags on the wires. This is simply little pieces of paper with a large number written in sharpie on them and then taped on with a long piece of packing tape to basically laminate them into place. This makes it really easy to know which wires you have without having to guess. All of this wire is high flex, silicone insulated wire and is basically tangle free for the most part, where has this wire been all my life??? Turns out it was on Amazon all along…

Another item I have fallen in love with is these little Velcro cable straps, I don’t know why I didn’t get these sooner, but these things are a wonder of modern technology for wire management and keeping your gear organized. If you have never used them, I highly recommend grabbing a pack of them off of amazon, it will change your life!

So, since I had a way to wander off of 20 meters, wandered I did! I didnt get on 20 meters at all today. Today I stayed on the other three ham radio bands that I could get on and got 16 contacts in about 45 minutes even though it was super cold and I had the power, on the first two QSOs, turned down to 1 watt! Yes, ONE watt! Now, they are only a few hundred miles away to be fair, but still, it is a single solitary watt going the distance here! AA5JF was a little over 200 miles from me and he heard me really well if his signal report is accurate on that little single watt of RF power. The other person (W4EDN) was 265 miles away and I still got a good report. This just goes to show that you don’t need really big guns to have some fun with radio, it is something that even people who can only get small QRP kit rigs and build them can make some contacts. Now, would have I made more with more power? Of course I would, more people could have heard me and I am not contesting that. My point here is people seem to get it in their head that you need 100 watts to be able to have a QSO on HF, when it just ain’t true. Now, I cant speak of phone contacts here as I don’t do very much HF amateur radio on phone modes, I am almost exclusively a CW op…hence the love affair with the K1. So take all that with a grain of Morse code… Once I remembered I was running 1 watt, I noted it at the top of the log and turned up the power to 7 watts (I thoguht I would see how the signal reports changed with 7 times the output power and the log speaks for itself. The first report on each line is what I sent them and the second report is how they heard me. Once I moved to 17 meters I turned the little K1 to 5 watts and left it there for the rest of the activation.

It was easier for me to get some Park to Park QSOs today with the “hunt and pounce” method…but it was more like the “hunt and wait till they can hear me” method actually, all the joking aside, it worked and I got three parks in the log today because of it. I didn’t keep the activation going any longer as I had some chores to do as well as my feet and fingers were getting numb. Numb fingers and toes makes it hard to log and send decent code so I went QRT with 16 QSOs in the logbook for today. All in all, it was a successful trip with me testing all three of the other bands I don’t normally use and the random wire turned out to even be resonant on the 40 meter CW band somehow. What luck! Maybe future me will have written about how my trip to Hawaii was successful and you will see that blogpost in a couple of weeks once I have had time to write it. So till next time, go get your radio out and take it to a part or something.

High Temp Activation

Today I went to my favorite park and set up my IC705 radio to work an activation on Park K – 2169. The only difference today that was unusual was the fact that it was in the mid-90s here in Georgia, this usually is not a big deal but when I finally got my radio set up I was in the direct sun. This causes the radio to heat up very quickly and I found myself with a radio that was so hot that I could almost not touch the case in less than 30 minutes. So I moved the radio to inside my backpack to where I could shield it from the Sun as the shade moved closer and closer to my operating position. Eventually the shade got to the end of the table and I was able to get the radio out of the Sun. For the period of time that I was working 17 m I learned that the reverse beacon network was not picking up my CQs and the POTA site was not posting my spots either. These two items combined caused a very long and “quiet” period of 17m operation… HaHa. I finally got 11 contacts on 17 m after considerable time of what seemed like endless calling of CQ. I had my antenna strung high in the tree, probably 25 or 30 feet up, ran up over a large limb on the first tree and horizontally at a slight upward slope to another tree as shown in the graphic I made from the photo I captured. I am still using the N6ARA tiny paddle for my travel key and it works wonderfully to this day. I have done well over 15 activations with this key now and it keeps on working perfectly. Once I moved to the 20 m band the game kind of picked up for me as I was able to make another 24 or so contacts in short order. This being mostly due to the RBN starting to see me and I was able to get the POTA spot to take when I moved to 20. The band would fade in and out some as I was working but for the most part I was able to work contacts about one per minute. It seems like that is the maximum speed that I am able to work a Morse code contacts with the speed I am able to operate (about 20WPM) and with the exchange information I choose to send. All in all, it was a wonderful day to get out and play with my radio and to get an activation in at the same time. My next activation will either be with a Ten Tec Argonaut 5 or my PENNTEK TR–35 radio as I want to try one of those out for an activation soon. I have had the TR-35 for a while now and have only used it a couple of times in the shack at home so far. This is a travesty as it is a wonderful little radio. I hope to take it on trips in the future as it is SO small!!!

If you have not checked out the parks on the air, set up an account with them and look at what they are doing. It is a wonderful program and has lots of activity for the amateur operator. There is usually a mode that is something that you would enjoy doing, that will have people on the air almost all the time. Whether you are into digital, CW, voice, or any other mode that people use on the air there is usually something going on with POTA. I even had two traditional QSO contacts today during my activation, complete with name exchanges, QTH exchanges, and even our rig exchanges. So there is no hard and fast rule as to what information is traded in an exchange but they do normally have a minimum of signal report and usually the hunter will send the state they are residing in (but it isnt required from what I can tell), that is about it, anything else is fair game. If you want to know more about it you can go to the Parks on the Air website to learn lots more about it.

Thank you and 73

I started with keeping the battery in the pack but eventually had to also put the radio in it to keep them both out of the direct sun.

The Antenna tuner is usually across the table to get the RF away from me somewhat.

ICOM AH-705 Antenna Tuner with my homebrew cable I made for it that has power, coax and control cable all in one bundle.

Antenna ran into the trees with the counterpoises run along the ground underneath them.

The IC-705 is a wonderful little radio that works really well for portable operations.

Not a bad day running 10 watts into an EFHW wire antenna!

Long lost friends in amateur radio

I have been doing POTA (Parks on the Air) for a couple of months now and have started to notice a few call signs that show up in my log more often than not. One of thsee calls is K9IS. Steven has “hunted” me at almost all of my activations, to the point that I now know his name when he calls me. His call sign just kind of “jumps” off the page at me for some reason. I dont know why this happens but it does occasionally. Maybe this time there was another reason???

Here is the dejavu part of the story. I was talking to my buddy across town (KG4WBI) on the repeater one night and we got to talking about the contact I made to Alaska from my jeep on a RCI Ranger 2950 10 meter radio using CW and I wanted to know the output power I was using that day, (Trust me this all ties together at the end) So I remember that I had used that particular QSL card in my WAS card set for my Alaska card, so I dig out the box and start going through the stack to find the Alaska card and what do I stumble across? A QSL CARD FROM K9IS FROM WHEN I HAD MY OLD CALLSIGN OF KG4WBH!!! Seems that day I was playing with my Rockmite 40 I had built and he was using a Ten Tec Argonaut 5. I just recently bought an Argonaut 5 and plan on doing some activations with it using a straight key soon. (Like next week if I can get the cable built). Anyway, this blew my mind that we had made contact so long ago and now we are meeting on the air reguarly to make POTA contacts and we didnt even know it.

I was using a Rockmite 40 that day and it only uses about 500milliwatts of output power, hence the QRPp note.

I reached out to Steven and shared my little discovery with him and we both had a good laugh out of it. Neither one of us had remembered the QSO back in 2003 on April Fool’s day…till I found that card. This is one of the many reasons I like using paper QSL cards. It is fun to me to wax nostalgic and read back through these cards at times. Especially the ones with additional inserts sent with them that had background info about the operator or some cool little tidbit about the local area where they lived. It is a treasure trove of information. You should look into using paper QSL cards if you have not done it before. It isnt for everyone, but at least take a look. If you want to send just select cards on occasion, you can even make simple cards in photoshop for a specific event and just print photos of them, that has worked for me in the past more than once. I even used the discount version of Photoshop… GIMP. Anyway, let’s climb out of that rabbit hole and get back to the original story. HAHA

This is why I like paper QSL cards.

PS: By the way, the output power to Alaska that day from a modified 102” stainless steel whip mounted on the back corner of my jeep was just 8 watts. The bands were good to me that day.

PSS: If you noticed, my old callsign and my buddies call sign are sequential. We did this on purpose as we wanted to try to have sequential calls when we decided to get our licenses. I have since acquired a vanity call after getting my Amateur Extra ticket, but Roger still has his original call even though he now has his General.

The WK4DS POTA Hunter Station Amateur Radio (and a little ragchewing too)

What does a simple POTA hunter HF station look like? Just like any other HF station… This is what mine looks like currently. If you haven’t already figured it out, I have a Ten Tec fetish and I don’t care 🤣 The Omni VI+ was a dream rig back when I first got into radio and I could not afford one at that time, but as time went on, I was able to piece together a nice station sans amplifier…for now… and I have really enjoyed using this old girl on the air. I also have the 238 manual tuner in the closet as well waiting on a time when I will need it.

My current station mainly consists of a Ten Tec Omni 6+ with matching power supply and automatic antenna coupler that I run primarily into a vertical antenna I have out in the yard. I still need to finish the installation of my wire antenna in the front yard in the trees so that I will have a second antenna to work with that will complement the station. I also have a splitter worked out to where I can set up and use my QRP radios in the shack easily. This allows me to test the radios and learn how to use them before I go into the field to do an activation. This reduces the stress of figuring out the radio in the field while trying to make contacts.

My current key of choice is the Ten Tec KR 40 keying module, this key is designed to work with their older radios and is able to do all sorts of things other than just keying output. It is an electronic work of art to simply be a key lol. I also have my other regular keys that the radio will operate with since it has a key input and a paddle input on the Omni. Not to be left out I also have a Logickey K3 keyer that I am going to get working as well. This will also make me have memory keying with my Omni since it does not natively have a memory keyer built in.

I am planning on adding a second HF rig to the shack to complement my Omni 6+ so that I can have the Omni calibrated and have a couple of small issues repaired on it and while it is out. Having the second rig makes it to where I will still be able to operate. I am currently searching for one of several radios to fit this position in my shack, such as the Ten Tec Jupiter/Omni 7, the Ten Tec Eagle, the Ten Tec Orion, or even something simple and small like a Kenwood TS 590 or similar. I really want nice filtering as I like to listen to CW on the air regularly and it is very tiring to listen to the bands with a lot of band noise. A radio with good roofing filters or IF filtering makes this a much more pleasurable experience. That is all my ham shack at home has in it to hunt stations with. My current antenna is a 17 m vertical that I can tune all the way down to 40 m and still have a decent signal going out. This is why I want to put a large wire antenna in the front yard. I really want to be able to work the lower bands and the large wire antenna will allow me to do that. Thank you for following along today and if you have not done it yet please subscribe to my blog thank you very much and hope to see you on the air soon. last but not least I have a good old 2 m radio to get on the local repeater and talk Symplex to my local buddies with. Everybody has to have a 2 m rig to get on the repeater ha ha.
