Today saw the old red Chevrolet transporting my POTA gear over to Chickamauga Battlefield National Military Park which is park number US-0716. I have activated this park many times in the past, but unbeknownst to me was that the location I usually used to activate this park also allows for the activation of the Trail of Tears National Trail as well as it follows old HWY 27 right through the park! I have been activating a 2fer for years now and had no idea…live and learn.
This “parking lot” has only 2 spaces in it, but it is close enough in proximity to the main road to allow for a 2fer when activating POTA
I arrived on station to find that only one spot was available and no one around the truck. This matters as Dan (K2DTS) had mentioned dropping by to see the CW setup and to observe a CW activation for a little while. Turns out the car in the other space was not him. He would arrive later, which was a much needed “shot in the arm” to lift my spirits. You see, today was one of those days when the sun was really angry while I was setup to activate. The solar K index was either 5 or 6 which isn’t good…especially for QRP… My QSO count today was not all that high, but I still had a relaxing and fun time at the park none the less.
This location works well with my truck mounted antenna setup that I built. I used my old reliable hamstick collection today to get on the air and true to form, they worked pretty well. I have also refined my tuning system as well. I will give you the quick rundown on how I do it now. This works especially well with hamsticks as you will soon see.
Hamsticks are a very viable antenna system for POTA activators. They are easy to setup and work reasonably well for their tiny size. They usually have good power handling so digital modes like FT8 and even good ole CW are not a problem for them. Of course SSB is always fine if they can handle CW…
My Hamstick Antenna System and Color Coding Setup
Above is my modest hamstick collection to date. This is the 5 bands I use the most and I wished I also had the 10 meter version as well…but I digress. It is a good idea to do something to tell them apart. The labels are not very durable from what i have seen and so I chose to color code mine with various colors of electrical tape instead. Red - 40meters; Blue - 30 meters; Yellow - 20 meters; Brown - 17 meters; and Green - 15 meters. These are what I have been using for a long time now and they work well. These are made by three different companies too so the brand doesn’t really seem to matter. I have also converted mine over to the QD attachment design so that I can change bands fairly fast…well it is faster than threading them into the socket…haha. I have owned and used this exact setup for quite some time now as you can see from this blog post I wrote a good while back.
I also store them inside a PVC pipe I made into a storage tube. It is almost 8’ long so I can keep the “stingers” on all the base load coils which prevents me from mixing the wrong tip with the wrong load coil. I built this tube steel mount to fit inside the 2” receiver on a pick up truck, this allows for it to do two things at once. 1) It allows the antenna to be setup quickly and easily on any vehicle with a standard receiver mount. 2) I also built it so that it makes the base of the antenna at around 6’ above the ground. Getting the antenna higher does help with take off angle so I made the decision to make it taller than most. This also made it possible to string some radials at various angles so I can play with the impedance by adjusting the radials. If you look close in the lower photo, you can just see the radials connected to the base of the mount and running down out of the frame. These were tuned for 17 meters like this and they worked incredibly well in this configuration. When you only have a few watts like with the Penntek TR-35, you need all the help you can get…haha.

I setup in the passenger seat again, but to be honest, this was not ideal. I struggled to get all the stuff connected and stationary today. I also had a problem with the battery in the little power pack I had built…it was completely dead for some reason. I had used it recently but I didn’t think I had tanked it, anyway, not to be dissuaded I decided to get out the 8Ah battery and find a spot for it as well so I could power the station. You see, I needed the “power pack” so I would have a speaker. I figured that since Dan was going to drop by and hand out some, that I would make it to where he could hear the CW as well. This setup finally settled in and I was able to get on the air. This is when I figured out that the sun was angry…
I looked on the POTA spot page to look for a clear spot and there was only one other ham on the spot page, on 20 meters, in the middle of the day… Do you understand what this means? 20 meters is literally the honey pot of the HF bands when it comes to POTA. There is literally 2 dozen CW ops at times on this band and then there will be 2 on 17 meters. It will be that drastic and today there was me and one other guy in the Carolinas and that was it. Optimistic that I could at least get my ten in short order, I fired up the radio, dialed through the literal ghost town that was 20 meters and settled on a frequency around 14.063mhz and started calling CQ. It took about an hour to get my ten plus a few more, but I finally got them. In an attempt to get some stations I could hear in the noise, I even switch to headphones as you can hear MUCH weaker signals if you goto headphones over the external speaker that I am using. This trick didn’t work either as it turns out, that there has to be stations on the air for you to actually hear them… I had seemingly forgotten this minor detail on this day…lol.
POTA CW station ready for use, including the Penntek TR-35, home brew S meter and battery pack/ speaker combo unit. Also the Gemini travel CW key and the Dell Inspiron computer with HAMRS for logging.
CQ Ham Radio - Gemini travel CW key is really well designed and cost effective. This is one of my favorite CW keys when I dont have a surface to set the Begali Traveler on.
The Gemini CW Key: A Collapsible Treasure from eBay
Let me introduce you to one of my favorite travel CW keys that I use for POTA operations. This is a key I bought off of eBay initially and as of this writing, it seems to be the only place to get one of these keys now. Maybe an opportunity for a creative solution here… lol. Anyway, these are darling little keys that work beautifully and I always enjoy getting this one out. As you can see below, the reason I like this key is how it stows the handles when not used. You simply loosen the screw on top a little, slide the screw to the rear and this collapses the paddles inside the housing which protects the from damage when stored in less than ideal conditions. This key also is dead simple, lacking any sort of adjustments at all, you just plug it into the radio and use it. I like that to be honest…
GHD CW Key for portable CW operations like POTA.
Operating QRP During a Solar Storm (And Why 20 Meters Was a Ghost Town!)
So after I struggled around for a little over an hour to put 15 calls in the log…well…14 since one was a dupe… (duplicate calls on the same band, park, day and mode dont count to your POTA score)…I decided to put up the headphones and get out the HF Signals sBitx and work some FT-8 on 17 meters. I had not seen Dan so I figured the honey-do list got him or something and put away the CW gear while FT-8 hummed along in the background.
A lot of times, I will run FT-8 while I do house keeping chores like putting up radio gear from a different mode that I had just finished using or talking to the wife on the phone about what she wants me to do next after I finish playing radio… you get the idea. I can do some other things while keeping an eye on the display and letting it run in auto mode for a while. Well, not today buckaroo, seems the band were so bad that I couldn’t get auto to work today very well. I called CQ for a while to no avail. I finally started hunting other stations can answering their CQ instead. Switching to this tactic netted me 5 more contacts before I closed out the log for the day. 18 valid QSOs will do just fine…actually, 36 since I activated the 2fer today!
If you will notice the waterfall in the photo below, you will see that there really were not that many stations on the FT-8 segment…which is usually choked pretty tight with stations. The bands were just that bad. Even with these terrible conditions, I was still able to get 5 calls in the log for today on FT-8!
sBitx by HF Signals is a SDR powered by a Raspberry Pi 4 or Pi 5 SBC and does all sorts of things a regular radio can not do.
Meeting Dan (K2DTS) and the Ham Radio Community
While I was taking some of these photos and cleaning up the unneeded ham gear after switching to FT-8, look who stopped by to say hi and see the station! Dan (K2DTS)! He missed my CW portion of the activation and instead of setting it all back up, I did show -n- tell with him about all the gear I had brought to the activation. You have to understand that this is fairly substantial…haha. We talked for probably 20 minutes or maybe even a little longer about all sorts of things and had a great eye-ball QSO. I hope we can link up again at some point so I can get him on the air with CW so he can make some contacts too.
Ham radio is a wonderful community that has a large number of great people like Dan (K2DTS) who came out to the activation site today to see the setup.
Some days you don’t have to make a ton of contacts (although this never hurts…haha) to have a good time. Any day at a park with a radio is better than your best day at work. Knowing this I will always choose POTA over going to work… lol. Thanks for coming along today and I hope to work you on the air soon!
