“Fly-Away Kit” QRP POTA Activation
by Conrad Trautmann, N2YCH
4/15/2023
The National Association of Broadcasters convention is an annual event that takes place every April at the Las Vegas Convention Center in Las Vegas, Nevada. This year, I traveled to the show for work and made some time to activate a park and get another state ticked off my “Activated US States” list. I also didn’t want to miss getting the Spring 2023 Support Your Parks Weekend activator award.
A colleague suggested I visit Red Rock Canyon National Conservation Area, K-7494. The park, which is operated by the US Bureau of Land Management, has a 13 mile scenic drive that has various parking areas you can stop at to get out and explore. Red Rock requires a reservation to visit and costs $20 to enter the scenic drive area. There are places within the park you could activate for free, but I took advantage of my military veteran benefit of free admission and drove the trail and activated at one of the scenic overlooks.
Before I traveled, I had to decide what radio and antenna to bring. I selected the Elecraft KX3 and the AX-1 antenna. Not having to check a bag was key to deciding what to take.
I packed the cables, battery and computer in my brief case and the radio and the AX-1 antenna went into my carry-on bag. I did get pulled out of line by the TSA at JFK airport, but the TSA agent was very nice and just asked a few questions and let me through with no issues.
Before I traveled, I took a look at the park page on the pota.app website and saw that Colin, AK7LV, was the park leader in QSO’s. I looked him up on qrz.com and sent an email asking if he had any good advice for me or could give me some pointers. He responded quickly with suggestions of his favorite locations, how to get to them and even a suggested location where I could pick up a twofer at a trail that crossed through the park. He said I should call him when I get into town. Continue reading N2YCH’s “Fly-Away Kit” QRP POTA Activation→

Necessity is the mother of invention
by Scott (KK4Z)
Plato’s Republic he said that *our need will be the real creator* or the proverb as we know it today *necessity is the mother of invention*. Recently, my friend Thomas K4SWL acquired a Yaesu FT-891. During his YouTube video, he expounded on how much fun he had with it. It did indeed look like fun. During this time I was pondering about doing more day activations instead of overnights. With the cost of everything still climbing, the need to conserve becomes apparent. I thought an FT-891 might really be a great radio for these day activations. Then reality set in.
I already have a number of projects I am working on and misc things like maybe having to replace my old 33′ push-up pole, it was not in the stars nor was there a twinkle in my wife’s eye when I mentioned it. In reality, the IC-7300 is a great radio and does everything I need to do especially in the field. I don’t need another radio, I have three 100 watt radios and three QRP radios. I still wanted an easy setup for these one-day activations. I want to drive to a park, set up in a few minutes, operate, tear-down in a couple of minutes, and head for home or another park. I also wanted to make my day activations park ranger friendly. To me, that means trying to be inconspicuous.
I have two projects planned. The first is a desk for my truck. I am making a desk to sit over the center console and front passenger seat big enough to hold my IC-7300, a laptop and a CW paddle. My plan is to secure the desk to the truck and the radio to the desk. I also wanted to make this as cheaply as possible. I used stuff I had on the property such as a half sheet of plywood and some construction lumber. The only things I had to buy were some screws and eye-bolts, about 14 dollars worth.
The plywood was cut to 24 x 38.5 inches. The length covers the center console and front seat while still allowing me to get to the heat/AC controls. I gave the corners a generous radius and I broke the edges with a router. On the underside, I used a 2 x 12 to make a spacer for the center console where the cup holder is and a leg for the other side over the passenger seat. The spacer is glued and screwed to the desktop but the leg is not attached. This is to make it easier to store. I made a socket for the leg using 2 x 2’s. It’s probably easier to look at a picture than me to try to explain. I added eye rings to the rear of the desk and use a bungee cord to secure the desk to the passenger seat. The only other thing I did, sprayed the top with polyurethane. Note. I am not a carpenter or cabinet maker. I use rough hand tools to get the job done and I am often making do with what’s on hand or what’s the cheapest way to do it.
Since I first met Brooks, he’s always had a goal of learning CW and activating parks and summits using Morse Code.
I’ve been in touch with Brooks regularly over the past year and have followed him as he progressed on his CW journey.
Though, like me, he has an active family life, Brooks has found the time to practice CW both through lessons and actual on-the-air contacts. Fortunately, this is all possible because–again, like me–his wife and family are very supportive of his amateur radio adventures!
Early this year, we met on 80 meters and had a good one hour rag chew at about 12 words per minute. I could tell he was ready to do his first POTA activation in CW.
To give him a little real-world practice, we decided to hit the field on a day when I was performing an activation and he could log for me in real-time.
Fast-forward to 8:30 AM on March 24 when Brooks and I met at the Folk Art Center on the Blue Ridge Parkway. Coincidentally, this is the same location where I performed my first CW activation!
We deployed his MFJ-1984MP 40 meter EFHW (End-Fed Half Wave) and connected it to his Xiegu X5105 transceiver in very short order. Brooks also chose his lucky CW Morse paddle for this activation.
But before hopping into the field report, let’s back up just a bit…
First CW Activation: Getting there…
Brooks very kindly wanted to share a bit about his CW journey in this field report. He writes:
From the moment I knew of its existence, becoming a POTA activator using CW has been at the top of my “radio bucket list.”
It seemed like the ultimate challenge and I knew I would never be satisfied until I was able to confidently activate parks using CW. There is also a bit of mystique to CW that other modes lack, making it inherently more interesting to me. In this article, I am going to share the path I took to learn CW and how it culminated in a very successful CW activation.
The day after my activation of Park Babelsberg, I wanted to activate a second new POTA park. The new Park Sacrow is a picturesque park located on the River Havel in Potsdam, about which I have written a brief summary in the QRPer activation report for Park Babelsberg.
One of the prominent landmarks in the Park Sacrow is the Heilandskirche, also known as the Church of the Redeemer.
This neo-Romanesque church, completed in 1844, is a striking sight with its red brick façade, white stone accents, and tall tower. The Heilandskirche is overlooking the Havel River and offers panoramic views of the surrounding park and river.
During the time of the Berlin Wall, the Heilandskirche in Sacrow was located near the border between East and West Germany. The church was in the “No Man’s Land”, i.e. behind all East German border barricades – see photo from 1972 below with the Berlin Wall – preventing anyone from visiting.

After the years of decay, when the bad condition became too obvious from the West Berlin side, citizens of West Berlin tried to stop the further decay. After long negotiations between church authorities and the government of East Germany, the exterior of the church building was restored in 1984/85. Today, the church looks as beautiful inside as it looks outside.
With the border between East and West at the middle of the river, the whole area was a kind of border protection zone, only available to locals or those with a special permit.
The park is close to the Glienicker Bridge, also known as the “Bridge of Spies” from Steven Spielberg’s blockbuster, on the opposite of my position the day before.

As mentioned in my previous report, I have grown up less than a mile away from this famous bridge, in Potsdam, i.e. Soviet controlled part of Germany.
In my opinion, Steven Spielberg told the wrong story. There is another, more interesting story related to this bridge. It is the story of the Military liaison missions. A few British, US and French army members were allowed to roam freely in the Soviet controlled part of Germany and, vice versa, a few Soviets in West-Germany. These members of the military liaison missions had immunity from all German authorities. Since East Germany was frontline to the western world, the Soviet army had their most advanced technology there and the mission members’ task was it to spy, for example with this US Military Liaison Mission vehicle – note the license plate.
US Army
The uniformed, but unarmed mission members drove military-green cars with a special license plates – here a British mission car on display in a museum. For me as a child, those cars looked like from another planet.

The Glienicker Bridge border crossing wasn’t open for public, but only for those mission members and diplomats. The French and British mission houses were close to this bridge in the Soviet controlled part, the one for the US was some miles away.
French Mission House today:
British Mission House today:
Just imagine these two buildings with a huge British and French flag on top, in proximity to Soviet military installations behind the Iron Curtain.
It did not always go as smoothly as it could. The image below shows the Soviets handing over the corpse of Major Arthur D. Nicholson to the US authorities on the Glienicker Bridge. Nicholson was shot down in 1985 by a Soviet sentry at a Soviet army base in East Germany.

In 1984, Philippe Mariotti, a member of the French Mission Militaire Francaise de Liaison died after the East German Secret Service has set up a trap and rammed Mariotti’s car with an army truck.
The British BBC aired an interesting documentary about the British mission The British Commanders’-in-Chief Mission to the Soviet Forces in Germany (BRIXMIS) called “The Brixmis story”. If you find the topic interesting, there is a lot of stuff on YouTube when searching for Brixmis or USMLM.

POTA Activation K-3620 Florida Keys Overseas Heritage Trail State Park.
By Dave (KN4OK)
On April 8th, 2023, on our way to the Overseas trail near the 7 mile bridge, is a great place to activate with a picnic table and shade on the water.
I was smart enough to mention to the wife that we were going to activate a park and she was carrying my Elecraft KX2. Of course, in my hand was the antenna, the MFJ-1889T, and counterpoise wires that I borrowed from my WRC antenna.
After a mile hike on the trail, we stopped at the picnic table and I set the station up on 17 meters CW. The SWR was pretty good and I made 9 contacts with no problem. I then switched the radio and antenna to 20 meters and obtained a better SWR.
One thing that I noticed: extending the counter poise wire (33ft) all the way out for both bands helped a great deal. The jumper holes on the antenna were also changeable and helped as well. MFJ has a nice manual for band setups, but be sure to adjust for best SWR. Very easy to do and works great.
The 20 meter band was also a big success and I was very pleased with the performance of the MFJ 1899T antenna. Thanks for all the previous discussion of the similar antennas that inspired me to take out my antenna.
The end result was 19 contacts, all CW in about 45 minutes on a beautiful day!
Over the past couple of months, I’ve been trying to give the Xiegu G106 a thorough workout in the field. This little HF QRP radio is on loan to me from Radioddity who has very kindly been quite flexible about the loan period.
I want to give the G106 a fair shake-out because I believe it must be the least expensive multi-mode, full HF coverage transceiver on the market. Field ops are always looking for portable, affordable, effective radios to take to the field so many are considering the G106.
Of course, you simply can’t get benchmark performance out of a low-cost leader.
My full review of the Xiegu G106 will be in the May 2023 issue of The Spectrum Monitor magazine. It’s one of the longest reviews I’ve published in TSM because I try to fully explore the pros and cons of this pint size rig in order that pretty much anyone can make a purchase decision based on their own preferences and requirements.
POTA Plan B
On Saturday, March 18, 2023, I decided to take the G106 out for a very brief activation during a return trip to my QTH.
My park of choice was Tuttle Educational State Forest (K-4861) because it’s conveniently located, is an excellent POTA site, and I wanted to fit in a quick hike as well. Tuttle’s two mile loop fit the bill perfectly.
When I arrived at the park entrance, however, the gates were closed. I had double checked Tuttle’s schedule in advance and was under the impression that they had started opening the park on Saturdays again for the season.
I really wanted to fit in a decent hike so the next logical park choice was Lake James State Park. It didn’t require a major detour and I was certain it would be open.
Lake James State Park (K-2739)
Lake James has two major access points: the Paddy’s Creek Access and Catawba River Access.
I prefer the Catawba River Access even though it’s much smaller than Paddy’s Creek. For one thing, it’s always less busy and they’ve better spots to set up for POTA (since I like hanging wires trees more often than not). Although the Catawba River access lacks the trail network found at Paddy’s Creek, they do have a few trails that can be stitched together for a nice workout.
After arriving at the park, I put on my hiking boots and walked the Fox Den Loop and a bit of the Lake Channel Overlook.
I hiked back to my car, ate a bite of lunch, then grabbed my radio gear for some cheap POTA fun!
The holidays seasons like Christmas or Easter provide an opportunity to return to the family. So I drove across Germany to Potsdam, where I have grown up, during the extended Easter weekend.
Potsdam is a historic city located in the state of Brandenburg, Germany, next to the capital Berlin. It has a rich history dating back to medieval times, when it was founded as a settlement on the banks of the Havel River. In the 18th century, Potsdam became the residence of the Prussian royal family and was transformed into a center of arts, architecture, and culture. The famous Sanssouci Palace, built by Frederick the Great, is one of the many palaces and gardens that reflect the city’s royal heritage.

Close to the Sanssouci Palace, the Neue Palais, a grand palace, is located. It is a magnificent example of Baroque architecture, with its grand façade, opulent interiors, and beautiful gardens, and it was used as a guest residence for the Prussian royal family. Later William II, German Emperor and King of Prussia, made it to its main seat.

Potsdam was also a significant location during World War II. During the last days of the war, the 12th German Army tried to break through the Soviet blockade around Berlin, which caused fierce fighting close to the city.
Less than a month before Germany’s final surrender, 1700 tones of bombs were dropped causing destruction of a large part of the city center. Still a lot of dangerous stuff from those times is found during construction works until today.
The city also served as the site of the Potsdam Conference in 1945, where leaders of the Allied powers met to discuss the future of post-war Europe – here with Winston Churchill, Harry S. Truman and Josef Stalin during July 1945.

Before I started the trip, I checked which ham radio programs offer outdoor activations in the region. The whole area is more or less flat, so not SOTA summit within a radius of a one-hour drive. Also, no POTA park existed, so I thought suggesting two would be good, for me and POTA :).
One new park later accepted by POTA was the Babelsberg Park with its Babelsberg Palace. The palace was the summer residence of Prince William, later German Emperor William I and King of Prussia, and his wife.

From the park, you have a good view to the Glienicke Bridge, probably better known from Steven Spielberg’s movie “Bridge of Spies”.
The Bridge of Spies connects Berlin (formerly West-Berlin part) with Potsdam, (formerly East Germany), hence formerly the Soviet and Western (US, UK & France) controlled parts of Germany. The bridge was used as an exchange for spies between Western and Eastern powers. Probably most prominent was the CIA pilot Gary Powers, who was shot down over the Soviet Union with a U-2 spy plane in 1960. Below is an image of the beginning of another spy exchange in 1986.
The kit version has been delayed for the time being due to several (most) beta builders experiencing frustration with the process of assembling the front panel onto the main board with 15 loose and unsoldered switches, jacks, and controls. These issues indicate that the TR-45L kit version will most likely be offered as a semi-kit with the main board being largely factory assembled, leaving the pre-aligned plug-in RF board in kit form. The internal battery option would be available in this kit version, but not the Z-Match ATU.
TR-45L Skinny (left) TR-45L (right)
A second kit version in a thinner housing is also being considered (see the TR-45L “Skinny” photos). This version would be offered with no options available (other than a $20.00 tilt bail) as there is no room inside the thinner housing for the internal battery nor the ATU option. It does, however, contain an internal speaker. Unfortunately, while greatly simplifying construction, these semi-kits will erode the normally expected cost savings with a kit. The best guess price for these TR-45L semi-kits would be around $500.00. We welcome your thoughts and opinions on these semi-kit concepts.
For those interested in signing up for the reservation list, you can use the reservation form linked here. Be advised, it could take up to 6-8 weeks until they are ready to be shipped.
The TR-45L has been a long time coming, and I thank you for your patience during the development cycles with parts procurement issues due to the covid pandemic. Let’s hope that the ugly covid experience is behind us…
In a nutshell, the TR-45L Skinny will simply be a TR-45L in a skinnier chassis with no option for an internal battery nor Z-Match ATU, but will still have an internal speaker.
For those of you who don’t care for the Z-match or internal battery, the TR-45L Skinny will certainly be more portable and less bulky than the original TR-45L.
I suspect the performance will be identical. I’m sure the internal speaker will work well, but I will be curious if it sounds as full-fidelity as the original TR-45L. I might ask John for a loaner to check it out once released!
Again, if interested in this variant of the TR-45L, you might wish to fill out the reservation form.

Mini Field Report: Testing the Gabil 7350T and BaMaTech TP-III on a brisk SOTA activation!
by Steve (MW0SAW)
Went for an early walk/SOTA activation up Fan Fawr GW/SW-005 (734m) this morning (9/4/23). I think someone said it was supposed to be the hottest day of the year in the UK. It was about 5 deg celsius with a bitter wind chill of -2c on the summit! It’s very close to the highest peak in South Wales, Pen Y Fan (886m).
As I mentioned a couple of weeks ago in our emails, I wanted to test a new compact antenna I purchased recently, called the Gabil 7350T in the USA, and branded as the Sharman MD-3500 in the UK where I got mine. I also took the Gabil GRA-ULT01 MK2 tripod which I did purchase from the USA on Amazon.com.
The Gabil 7350T Compact Antenna and Gabil GRA-ULT01 MK2 tripod
Another first for the the activation was the Bamatech TP-III ultra compact paddle, Dinos were included 🙂
Starting my walk, the lovely view of the reservoir quickly disappeared and was the last view I would see ascending into the mist.
I took refuge in my Decathlon 1 man camping shelter, setting up the tripod and antenna close by.
The wind was howling and turning my back the antenna toppled over. This was quickly resolved with a tent peg on one of the tripod legs. Quick setting of the slider with the analyser got 1.2 SWR and so after a slurp of coffee, I started to call CQ on 20m CW. A nice stream of European qsos ensued with good reports (many 599), it was pleasing to hear with such a small antenna (about 8 ft). Just as the contacts were drying up, I was taken aback by a strong VK station! Always great feeling to get some dx like that but especially pleasing with this tiny antenna on its maiden voyage 🙂
I switched to 20m SSB for a few more QSOs but struggled with QRM on two frequencies. My allotted time was running low and my fingers were numb, so I packed up the HF and got the handie out to catch a few local VHF contacts.
So what can I summarise from this activation, well I can safely say I love the Gabil/Sharman antenna and Gabil tripod. They would make a really nice additional to a small go bag, they seemed to work almost as good as a full size 1/4 on 20m. Time was limited this trip and I was too cold to hang about to try more bands, but extremely pleased with the performance so far.
The Bamatech key is a pure work of art, beautifully made, sensitive and precise. Probably my best portable key to date in my collection.

Picture this .. you are getting a bit twitchy due to lack of POTA activation and you have run out of Potaxxia. Further, You publicly stated a New Year’s eve goal to make at least 200 POTA CW activation contacts per month for 2023 (there may have been beer involved), and now you must stay accountable to your goal and you are currently behind plan. It’s too early in the season to be lawn mowing while listening to podcasts such as QSO Today, Ham Radio Workbench, ICQ Podcast, AP/DZ or Soldersmoke. Thus, chasing contacts is [always] a good use of your time.
Lastly, if you are like me, the the solar indices are still an art form being learned and the numbers for today aren’t all in the green zone.
One of many charts that help decode the magic behind propagation values – click through for source webpage
So you begin to wonder just how much effort it’s worth to load up your gear and try to activate. You think to yourself that there won’t be much action on bands other than 20m which has been noisy lately, so why bother as it’s at least a 45 minute trip to the nearest POTA entity.
With this background, on Saturday I placed myself in the city at the nearest-to-home spot I could park in the south part of Calgary adjacent to VE-5082, the Trans-Canada Trail. I was trying to make the best of what I perceived to be a rough conditions day and had no real plan except a convenient location requiring minimal effort for a minimal return. My expectations were, sadly, met in this regard.
The author in a suburban and *very* RF noisy place that he won’t return to.
I was at the edge of suburbia with large homes on my left overlooking the ravine and pathway on my right. To say it was RF noisy would be a colossal understatement. I made 18 painful contacts in an hour and I’m sure people called me but I didn’t hear them given the S7 noise floor on 20m. At least I made one DX contact to Denmark along the way. Overall feeling frustrated, I went back home.
Sunday morning rolls around and again I wonder “is it worth it”?
