“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.

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 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.

It was the sort of day made for reading a good book by the fireplace or…in my case…activating a park!
I don’t let rain stop me from playing radio in the field. I carry a rain fly in my car pretty much all of the time so if push comes to shove, I can create a dry space to play radio.
That said, a number of parks I frequent have large covered picnic shelters, so why not use what’s already there?
That particular Friday, I had one particular park and one particular goal in mind.
I built this BCI filter specifically to pair with the Xiegu G106 transceiver. Why? Because the G106 is prone to overload if you’re anywhere near an AM broadcaster.
The last time I visited Fort Dobbs State Historic Site (K-6839), a local AM broadcaster bled through the audio of the G106. I was able to complete the activation without any issues at all–in fact, it was a very successful activation (read the report here).
Still, I did feel that the receiver was a bit less sensitive due to the broadcaster overwhelming the front end of the radio.
That Friday, I wanted to pair my Xiegu G106 with the new in-line BCI filter to see if that might mitigate the interference I experienced before.

The Visitor Center at Kinzua Bridge State Park (K-1366) is well worth a visit. It provides an excellent overview of the history, use, and collapse of the railroad bridge that gave the park its name, and it provides an excellent view of the pedestrian skyway built on the portion of the bridge that remained standing after the tornado that caused the collapse.
Reflections on Activating a Not-so-New Park
by Brian (K3ES)
Monday, April 3 was one of those beautiful, warmish (60ºF or 16ºC) sunny days in northwest Pennsylvania that remind us that spring is really here. Only a week earlier, we had an unexpected snow fall that covered the ground (and it will likely not be our last snow of the season). So my wife, her father, and the dogs all looked forward to getting out of the house to enjoy the weather. We packed for a picnic, and drove through bright sunshine to Kinzua Bridge State Park.
After a picnic lunch, and while Becky and her dad explored the visitor center and walked the dogs, I set up for a Parks on the Air (POTA) activation of K-1366. This would be my first activation of the park, but not my first visit. I have been there several times before, including an excursion trip behind a steam engine that took me across the railroad bridge over Kinzua Creek and back.
A view from the visitor center of the pedestrian skyway. It was constructed on the structure that remained after the bridge was struck by a tornado in 2003, causing its partial collapse.
An Historic Park
Kinzua Bridge State Park has an interesting history. The railroad bridge that gives the park its name was originally built of wrought iron in 1882. At the time it was built, the 301 ft (92m) high and 2052 ft (625m) long railroad bridge was the highest in the world. It was rebuilt in place in 1900, replacing iron with steel, to strengthen it for the heavier trains that needed to cross. The bridge remained in commercial service until 1952, and was later sold to the Commonwealth of Pennsylvania for a State Park. The bridge continued to support excursion trains and pedestrian traffic until 2002, but was struck by a tornado in 2003, causing its partial collapse. Today, the remaining part of the bridge has been rebuilt as a pedestrian skyway, complete with a glass floor at its end to look down at the valley far below.
The visitor center provides an excellent multimedia overview of the economics, technology, and history of the structure. It is well worth a visit. Similarly, the skyway gives a spectacular view of the structure, the collapsed towers, and the surrounding Pennsylvania forest. The park has picnic facilities and hiking trails, and a trailhead for the rail trail that has repurposed the old railroad right-of-way.
This is a view of the picnic pavilion from my operating position. The picnic area also has a number of other open picnic tables and a playground area for the younger crowd.
The Setup for Activation
I stopped into the visitor center to let the staff know of my intention to activate. I found them to be friendly and accommodating, which always makes activating a pleasure. I do my best to be a good ambassador for amateur radio and the POTA program.
For activating, I set up at a remote picnic table. Three tosses got the throw line over a good branch to support my Tufteln 9:1 random wire antenna. A 15 ft RG-316 cable connected the antenna to my Elecraft KX2. Completing the station were a 3 Ah LiFePO4 battery, a set of generic earbuds, and VK3IL pressure paddles. I used a clipboard to keep my notepad from blowing around in the breeze, while I logged with a mechanical pencil.
The picnic table operating station used to activate K-1366. Included are the KX2, VK3IL pressure paddles, clipboard and log.
The Activation
As I finished getting the station ready to go, it occurred to me that I had a frequency-agile-antenna and rig, a bit more than an hour to operate, and no other operators in the area. So, I took the opportunity to try for contacts on as many bands as possible, inching my way toward the POTA N1CC Activator award for making contacts on 10 bands from 10 parks. The park has good cell coverage, so I was able to use my phone to spot myself. After that, I mostly left things to the Reverse Beacon Network and the POTA spotting gateway, but I was able to use the phone to confirm that my changes in frequency were picked up.
In 70 minutes of CW operation at 5 watts, I made total of 26 contacts, including at least one contact each on the 10, 12, 15, 17, 20, 30, and 40m bands. An apology to the hunters may be in order, because I was harder-than-usual to contact. After making a contact on each band, I would QSY to the next at the first significant lull in the action. I look forward to another trip back to K-1366 to try for contacts on the 3 additional bands needed to complete its activation toward my N1CC.
As you might guess, by using multiple bands, the contacts came from both far and near: as far as Spain to the east and Oregon to the west, and as near as New York, Pennsylvania, Ohio, and Michigan. Middling distances were also well represented in the log.
It was a good day in the park, and here is the contact map from a 7-band activation of K-1366.

This outing made for a fun and productive afternoon that was all the more enjoyable for sharing it with my family.
It also made for a great opportunity to shake off the winter blahs, and it held the promise of beautiful spring and summer days for more park activations.

Here is a bonus picture of another semi-famous bridge in northwestern Pennsylvania (it actually has its own Facebook page). This is Nebraska Bridge, which provides a convenient shortcut across Tionesta Creek. We knew we would have to take the long way around, but stopped for a look anyway. Unfortunately the bridge floods several times a year (sometimes becoming completely submerged), because it is located in the upstream end of the reservoir behind the Army Corps of Engineers’ Tionesta Creek Dam. We had over an inch of rain last week, so the bridge is partially under water. On the brighter side, 100 miles downstream, the City of Pittsburgh did not flood.
