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!!!
