I’m very fortunate in that in the past few years I’ve acquired a number of QRP radios that I use in rotation when I do park and summit activations.
I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.
I’ve written formal reviews about most of the field radios in my collection. In those reviews, I try to take a wide angle view of a radio–to see how it might appeal to a number of types of operators. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.
The Getting To Know You series gives me an opportunity to highlight one radio at a time and showcase what I love about it and why it’s a part of my permanent radio collection. After we spend a bit of time talking about the radio, we’ll do a park or summit activation with it!
The Yaesu FT-817 and FT-818 Series
As I mention in my “Getting To Know You” video below, my very first dedicated QRP field radio was the original Yaesu FT-817 (non-ND version), so it has a special place in my heart.
At the time, I was living in the UK and travelling extensively throughout Europe with my UK call (M0CYI).
The FT-817 hit the market and it blew my mind. Up to that point, there were no general coverage QRP radios on the market that small, that comprehensive, and that even sported VHF/UHF multi-mode coverage. It even had a small internal battery pack! What?!
I was an early adopter of this radio and travelled with it extensively–indeed, in all of the years I lived in the UK and Europe, the FT-817 was my only amateur radio transceiver.
Fast-forward to 2023–some 23 years later–and I still have an 817. Actually, I have two 817ND’s and one 818ND (although, I plan to sell one of my 817NDs soon–I don’t need three!).
I find the 817/818 to be an incredibly robust and capable field radio. It’s also a brilliant value–few radios offer you the capabilities of the FT-817/818 for under $700.

Yaesu discontinued the FT-818ND almost exactly one year ago. Retailers no longer have new stock, but there are loads of them on the used market. Keep in mind that the FT-817/818 was a cash cow for Yaesu for over two decades–the used price remains fair because there’s just so much supply out there. I routinely see 817ND and 818ND models selling for between $375-700 depending on how they’re configured and what’s included.
Sunday, October 15, 2023, was the final day of the W4 SOTA campout. That morning, Joshua (N5FY) and I packed up our tents/gear then played a little radio at our campsite (at Lake Rabun). We weren’t in a hurry because the morning was so enjoyable. In fact, I think we checked out not a minute before the dealine of 12:00 noon!
We both decided we wanted to squeeze in one more radio excursion before driving back to our QTHs.
Tallulah Gorge State Park (K-2202)
It wasn’t realistic to fit in another SOTA hike due to our schedules, but Tallulah Gorge SP was an easy detour for both of us.
We pulled into the park and queued up to to enter. The park was absolutely teeming with visitors that day. I would have expected nothing less on such a gorgeous Fall afternoon!
Joshua and I found a quiet picnic area–with a few picnic tables spaced apart from each other–near the lake shore. It turned out to be a perfect spot to play radio. We spaced our sites far enough apart so as not to easily interfere with each other while on different bands.
Joshua set up his KX1, a wire antenna, and used VK3IL pressure paddles.
Joshua deployed his KX1 next to the lake and I deployed my KX2 a bit further up the hill.
I paired my KX2 with my “no transformer” random wire antenna. Of course, I used a Tufteln antenna because, I mean, N5FY was standing right there! ?
This antenna consists of two 28.5′ 26AWG wires connected directly to a male BNC. Simplicity itself on the antenna side. It’s the KX2 internal ATU that does all of the matching (since there’s no transformer). I find that the KX2 can match this antenna from 40-10 meters with ease.
I think the magic of these simple random wire antennas is that they’re directly connected to the radio. There’s a bit of efficiency in having no line losses, etc. even if the ATU does soak up a bit of energy.

Connecticut POTA/SOTA combined activation
By: Conrad Trautmann, N2YCH
November 24, 2023
The author, Conrad, N2YCH at POTA K-1717, Sleeping Giant State Park & SOTA Mt. Carmel, W1/HH-002
Looking for my next activation challenge, I wondered if there were any overlapping POTA parks with SOTA summits in the state of Connecticut. I’ve only done two SOTA activations to date, one in Maine and the other in New Hampshire. I thought, there must be a few in Connecticut.
On my home computer, I brought up both the POTA map and the SOTA mapping page and quickly realized that it would take too much time to try and compare the two maps. Instead, both sites offer KML exports, so I exported all of the Connecticut parks from the POTA site and the summits from the SOTA mapping page and imported both files into Google Earth Pro. A yellow push pin represented the POTA locations and a blue triangle the SOTA locations. It was easy to spot the overlapping sites. Mt. Carmel and Talcott Mountain are both POTA parks and Summits for SOTA. There are a few other SOTA sites that have POTA trails that cross over as well.
I decided to tackle Mt. Carmel, SOTA W1/HH-002 also POTA K-1717, Sleeping Giant State Park. I’d already activated Sleeping Giant for POTA before, but not from the summit. For a SOTA activation to count, the operator must be within the “Activation Zone” as defined by the SOTA rules.
The Connecticut state web site has good maps and information about the park and showed that the trail to get to the summit is an “easy” 1.6 mile hike. I thought that sounded like a reasonable distance. What they don’t tell you on the web site that it’s also a 600’ climb up in elevation from the trailhead to the summit. I knew it would require a climb, but I didn’t expect that. I made the trip up, but it was challenging, especially carrying my backpack with the radio, a VHF handheld, antenna, batteries, computer, water, etc. I plan to travel lighter the next time.
The Mt. Carmel trailhead
Before I get to the activation, a little about the park. It’s called Sleeping Giant because from a distance, the ridge looks like a person laying on their back.
It’s located in a mountain range called Hanging Hills which extends North from Long Island Sound through Connecticut and Massachusetts up to the Vermont border. Quinnipiac University is across from the entrance to the park and the Quinnipiac Indian Tribe once inhabited the area. Please indulge me as I also share the ghost story of “The Legend of the Black Dog of the Hanging Hills.”
“If a man shall meet the Black Dog once it shall be for joy; and if twice, it shall be for sorrow; and the third time he shall die.”
As the legend has it, the Hanging Hills area is haunted by the Black Dog. You don’t want him to cross your path three times. It’s this story that is the basis for the SOTA “Master of the Black Dog” certificate. “An activator must have entered valid activation logs from each and every summit in the Hanging Hills Region and must have survived all of the activations.” There are currently four summits in the Hanging Hills Region. I need this award.
So far, I have completed activating one of the four summits and did NOT see the black dog. Wish me luck on the remaining three.
The view about half way upThe Lookout Tower
The lookout tower at the summit is the main attraction of the park. Built in 1936, it is listed on the National Register of Historic Places. It stands four stories tall and is 739’ above sea level, providing a 360 degree view in all directions and a clear view over New Haven to Long Island sound. According to the Sleeping Giant Park Association, over 100,000 people visit it each year.
I’ll admit, after hiking the trail up, the last thing I wanted to do was climb four stories more. I did go up before I left to get some photos.
For the activation, I found a bench to set up on with space behind me to set up the Chelegance MC-750 antenna. I ran FT8 on 20 meters beginning around 10 am ET and after roughly 30 minutes, moved up to 10 meters. My experience running QRP on digital modes is that I will cover the Eastern half of the US and some Europe on 20 meters. I can usually make contacts out to the West Coast and into Europe on 10 meters especially later in the day. By activating on both frequencies, I tried to cover as much area as I could to provide the best opportunity for hunters and chasers to reach me.
Setup: MC-750 vertical antenna in grass behind bench and KX3 and computer on bench

Coverage from the summit: Yellow pins are 20 meters, Green pins are 10 meters
Looking at the map, you can see that I covered the Eastern portion of the US on 20 meters. It was also 10 am local time and still pretty early on the West coast. When I shortened up the antenna and retuned the KX3 for 10 meters, I started making contacts with Germany, Italy and other EU stations.
The hike down from the summit was much easier, the temperature had warmed up a bit and I stuffed my coat into the backpack for the trip down. When I got to my Jeep, I noticed a number of empty picnic tables nearby and decided to set up and get a few more POTA contacts while I was there. I ended up with 48 total for the day.
The summit I was at was an easy one (worth 1 point) compared to many and it was challenging to me. I came away from the experience with a new appreciation for the challenges SOTA activators face. I also came away with a new goal, to get the Master of the Black Dog certificate!
If you’ve been following QRPer.com and my YouTube channel for long, you’ll notice that I typically post two field reports with videos per week when my free time allows. Each report takes about four hours to produce along with a video. I’ve got a busy day ahead on the road (including a POTA activation), so in order to squeeze this field report into my schedule, I’m going to use my more abbreviated field report format: a “postcard” format!
Speaking of which….
Pisgah National Forest (K-4510)
On the morning of Friday, November 10, 2023, I had a couple hours to fit in some POTA time.
All morning, we had been receiving some much-needed rain in the form of scattered showers in a constant heavy mist.
I decided to explore picnic areas I hadn’t yet visited in Pisgah National Forest along the Pisgah Highway near Brevard, North Carolina.
I was curious if I might find a small shelter at one of the roadside sites. Unfortunately, I did not; however, I did find quite a few sites that were ideal for POTA with tall trees, space between picnic tables, etc. I decided to pick one at random that had no other park visitors.
I did have a small rainfly in the car I could set up, but I decided to simply risk it. The goal was to pair the new Elecraft KH1 with my (MW0SAW) End-Fed Half-Wave antenna.
I wanted to see if the KH1 ATU could match the EFHW on 30 and 17 meters (outside of its resonant bands of 40, 20, and 15 meters).

Woodbury Wildlife Management & Heritage Area (K-8151), Britton’s Neck, Marion County, South Carolina
by Bob (K4RLC)
Woodberry WMA (K-8151) is a 26,000 acre natural area over an hour inland from the Atlantic Ocean and formed by the confluence of the Great and Little Pee Dee rivers. Geologically, it is an area called the Coastal Plain given that in geologic time all this land was under the Atlantic Ocean. In North and South Carolina the Coastal Plain is basically land between Interstate 95 and the Atlantic Ocean. Historically, this land has importance as a site of many Revolutionary war battles. The namesake of Marion County is the famous American Revolutionary War General Francis Marion, known around here as the “Swamp Fox”. His military tactics against the British Army formed the origins of guerrilla fighting. Britton’s Neck is known named for the Britton family who settled the area around 1735 and operated the very important Ferry across the Pee Dee River, carrying farmers and their crops as well as soldiers. After this area had its timber harvested by a paper company, the state of South Carolina with help from the Nature Conservancy, acquired it.
I like to operate in such off the track places as it really feels closer to nature. Given that they have been activated only a few times, they are rare for POTA and many want to contact them, especially in CW. The dirt road coming in ran through an old cemetery, started in the early 1800s. On the other side of is a small cleared area with a kiosk that has a map and tells you what’s in season for hunting. In addition to the usual animals, the listing says that it’s always open season for feral pigs also known as wild Boar, given their destructive nature on the environment and nearby farmers’ fields. Near the kiosk is a metal mailbox like structure with a latch on it. When you open it, there is a sign in book where you list the date, your name, and what you’re hunting for. Five of the entries directly above me said they were “COON” hunting, and another hunter wrote “Hog”. For my listing I just wrote “radio” and thought that might puzzle a few hunters ?.
The set up was the usual with the old Alinco DX-70TH which is been used on the beach so many times, the beach sand and salt water in it now gives it a distinctive chirp on transmit. Old-timers let me know that a chirp was present (599C) but I think it’s just a unique part of the radio signal. The antenna was a 17 foot Chameleon MilSpec whip on a small metal tripod (no coil), set on top of a large aluminum screen wire mesh, now known as “the magic carpet”. As there were no picnic tables, I set up in the backseat of Alanna’s K4AAC van. Operating was pleasant with the cool day and no bugs. There were some other equipment issues. As the Alinco does not have an internal keyer, I used an old MFJ portable keyer with the key made from two stiff pieces of copper and rubber feet for pads. You get a forearm workout using this. (Apologies for my sending.)
Nevertheless, I quickly worked 40 stations all the way from Utah to Italy on 20 CW. This portable station was lighting up the Reverse Beacon with very strong signals up the East Coast and down in the Caribbean.
After activating, I wanted to explore more and drove the single lane dirt road further into the woods.
Cell service was pretty good and I got to talk with my uncle Randy who had been part of a hunting club here 40 years ago. Randy shared some stories of comradery, mostly hanging out with his young son Edward and friends, cooking around an open campfire, telling tall tales to each other. He knew the area well and told me I had about another 10 miles of dirt road before hitting a dead end at the river. As daylight was failing, it seemed wise to turn around and save the longer trip for another time. It was only fitting that in the dark, in the headlights in front of me, I saw a large black bear lumbering across the dirt road, dragging a dead deer behind it. This was truly nature.

Learning CW: Beyond the Basics
by Brian (K3ES)
I just finished my last class ever for learning Morse Code. It was a lot of work, but it really improved my ability to communicate using the CW operating mode. More importantly, this class taught me how to actually learn CW, by diagnosing the problems and barriers that inhibit improvement. Then it gave me tools I can use to overcome those problems and barriers at any stage of my CW journey. You see, I am not yet where I want to be, but I have made a giant leap forward, and I now know what I have to do to keep improving.
I guess it might help to tell you a bit about myself as a radio amateur, about the start of my CW journey, and about what motivates me to improve.
I got licensed in 2020, when I was working from home, and spending way too much time locked away from the rest of the world. I saw a video about amateur radio, and thought it might provide an opportunity for increased personal contact despite social distancing. I studied during my plentiful spare time, and passed the Technician, General and Amateur Extra license examinations in short order. Once I was licensed, Elmers at Skyview Radio Society near Pittsburgh, PA helped me to learn and explore the hobby, encouraging me to be radio-active.
I found a compelling niche hunting for Parks on the Air (POTA) activators, and I started hearing about all the benefits that CW brought for activating parks: tiny radios, efficient use of power, and automatic spotting via the reverse beacon network. That motivated me to work on learning Morse Code.
A full CW station packed for a hike weighs just a few pounds. This kit, based around an Elecraft KX2, fits in a small shoulder bag, includes all needed components and some spares, along with creature comforts for the activator.
I started my CW journey using a variety of apps and online tools. I practiced with club members. Thomas Witherspoon’s YouTube channel became a staple in my CW diet. Every character copied was a victory. All of this helped my ability and confidence.
I completed my first CW-only POTA activation in July of 2021, and have not looked back. But, during one of my early park activations, I had a defining experience. I could copy callsigns and standard exchanges with ease, but something off script would throw me off balance.
When a hunter finished his exchange and sent something followed by a question mark, I was lost. We worked through it, and after several slow repeats, I understood that he had sent “COUNTY?”. He wanted to know what county I was operating from. I easily sent him the name of my county, but the experience left me certain that I needed to improve my copy skills.
It doesn’t get much better than this. Operating CW under my favorite tree duing an activation of K-1345, Cook Forest State Park, in northwest Pennsylvania.
That certainty started me on a new phase of the journey, one involving formal training classes. I took a few classes, and each class helped – I could look back and see the progress. But none of them left me ready for CW communication beyond predictable exchanges. I knew there had to be an approach to me get there, and there had to be something more efficient than working endlessly to copy code bulletins or on-air QSOs between other operators.
CW Innovations provided just that method with their Comprehensive Instant Character Recognition (CICR) Course. CICR is not just a class, but a structured process for improvement, which includes self-diagnosis, targeted practice, a supportive learning environment, and partners working together to put new skills into practice on the air.
This figure provides an overview of the Comprehensive Instant Character Recognition Course. Modules focused on each of the elements are introduced as the 10-week course progresses. (Click image to enlarge)
Instantly recognizing a received character is liberating. Rather than performing mental translation, you learn to recognize each code sound pattern as a letter, number, or punctuation mark; in much the same manner that you immediately recognize the printed symbols making up the text on this page. CICR provides the tools and methods for achieving instant character recognition, but also emphasizes that new weaknesses in character recognition will continue to appear as your copying of code becomes more challenging. When that happens, it is time to circle back and further improve your recognition skills. The same tools continue to work. Continue reading Beyond the Basics with CW Innovations→
I’ve taken a wide variety of antennas on SOTA (Summits On The Air) activations, but one wire antenna I’ve always wanted to deploy is a simple vertical delta loop.
This summer, I mentioned to my friend Joshua (N5FY) that I planned to build a delta loop antenna and next thing I know, he built one. I suppose he’d been thinking about adding it to his line of portable wire antennas at Tufteln.
I was planning to build a 20M delta loop fed with twin lead, but Joshua’s choice is better for multi-band operating. His 20M delta loop features a 4:1 transformer so it can be fed with 50 Ohm coax like my RG-316 (which is also easier to pack than twin lead).
You might recall that I used his 20M delta loop antenna at Holmes Educational State Forest (see photo above) in early September. It worked a charm and wasn’t too difficult to deploy (loops are obviously more finicky than a one wire end-fed).
The great thing about this loop is it’s resonant on 20 and 10 meters, and it’s quite easy to tune on 17, 15, and 12 meters with pretty much any ATU.
Fast-forward to Saturday, October 14, 2023 when Joshua and I were participating in the W4G SOTA campout in north Georgia…
Yonah Mountain (W4G/NG-048)
It rained cats and dogs Friday evening into Saturday morning.
Fortunately, most of the rain stopped by the time I surfaced that morning.
Joshua and I ate a quick breakfast, grabbed our SOTA backpacks, then drove to the Yonah Mountain parking area/trailhead.
Last year, we also activated Yonah Mountain as well, but underestimated the hike and our timing. We ended up being a good hour or so late to our SOTA evening potluck. This time, we were keen to spend more time on Yonah Mountain and get back to the campsite in plenty of time to join everyone for dinner (and share exaggerated stories about our SOTA adventures).
Last year, we arrived at the trailhead and it was parked full. This year, even though we arrived in the morning and even though it was incredibly foggy/misty, it was still quite full!
Yonah Mountain is an incredibly popular destination.
Another fun fact about Yonah: it’s not really a beginner’s summit despite the fact it’s so popular with hikers and runners.
It offers up proper elevation change, gnarly trail portions, steep inclines, and about four miles of trail round trip. Although not an incredibly long hike, it’ll give you more of a workout than you might think first blush.
We reached the summit in due time and set up our stations about 30 meters apart.
The whole time, I was also monitoring the partial solar eclipse we were having that day.
I brought along some solar eclipse glasses and ended up sharing them with everyone on the summit. It worried me seeing so many young people staring at the sun with only their sun glasses or even–gasp!–with the naked eye. (I mean, weren’t they paying attention in science class–?) 🙂

Top Band POTA Activation Field Report
By: Conrad Trautmann (N2YCH)
November 15, 2023
In February 2023, Brian, K3ES, wrote here on QRPer.com about designing and building his own QRP portable random wire antenna he called the VK160 to work on 160 meters to make parks on the air contacts. This was in order to achieve his goal of getting the James F. LaPorta N1CC award where activating on 10 bands at 10 parks is needed. It’s not as easy as it sounds. As an avid parks on the air activator myself wanting to try activating on 160 meters, I built my own antenna based on Brian’s design and used it to get my first contacts ever at a park on the “Top Band.”
The Antenna
Brian used a 9:1 unun that he built himself in his design. Rather than build my own from scratch, I took a short cut and bought a QRPGuys 40m-10m UnUnTenna to use as the starting point for my VK160. Even though it says 40m-10m, it works on 160 meters, as you’ll see.
With shipping, it cost $36.00. It comes with all of the parts you need to assemble the antenna except for the wire. The main thing I liked about the QRPguys design was that the circuit board also doubles as a wire winder, so it’s all self-contained.
I sourced the wire from Davis RF and ordered 200’ of “POLY STEALTH – 26 AWG, 19 0.22000 44.00 STRAND COPPER CLAD STEEL, BLACK PE JACKET.” It cost $50 including shipping. The polyethylene insulation prevents the wire from knotting up. I measured out 144’ for the radiator based on Brian’s design and used the remaining wire as the counterpoise.
The completed antenna
I did a back yard test once it was all assembled and it worked great. For $86, I had created my own VK160. I encourage you to read Brian’s detailed design/build report here.
The POTA Activation – November 14, 2023
Now that I had completed building and testing the antenna, the next challenge was how to actually put it to use at a park. 160 meters doesn’t really come to life until dusk or after dark. In Connecticut, most state parks close at dusk. The park rangers clear the parks to close them at the best time to activate the band. However, there is one park nearby my QTH, the Stuart B. McKinney National Wildlife Refuge, K-0228, that has an annex called the Great Meadows Unit in Stratford with a nice parking lot that is not gated and has no posted hours. I arrived and set up at sunset, around 4:30 pm ET and operated from 5 pm until 6 pm. It gets dark here early in the Northeast US in November.
Another challenge is how to manage and string up 144’ of wire. Brian suggested an inverted V over a tree branch in his write up. There were no trees nearby, so instead I used a Spiderbeam fiberglass pole secured to my Jeep to get the feed point up in the air about 25 feet. I used RG58 cable from the feed point to the radio.
Spiderbeam fiberglass pole supporting VK160
Finally, I used one of my $3.00 Home Depot electric fence posts to secure the far end to keep it tight and up in the air and set up the antenna as a sloper. I laid out the counterpoise on the ground under the sloping wire.
By the time I had all of this set up, it was getting dark. I connected my Elecraft KX3 to the other end of the RG58 cable and to my surprise and delight, I was already receiving stations.
My KX3 has a built-in ATU and one tap of that ATU button and it tuned to 1.0:1. I started the activation right at 5 pm local time and in about 15 minutes, I had six QSO’s on 160 meters.
The PSK Reporter map showed me being received by stations on the dark side of the gray line in the Northeast. It was pretty much what I expected for QRP power on the low frequency. Then, the next ten minutes things were quiet. It appeared I had gotten everyone who could hear me.
Since this is a random wire antenna, it should work on all bands so I decided to test it on 80 meters. Again, the KX3 tuned right up and I got six more QSO’s. I was surprised to see Del, N2NWK from Washington, DC pop up on JT Alert. I have a an alert set for stations calling CQ POTA. Del was also at a park. I called and he answered and we ended up with a park to park. Anyone who knows Del knows that when you hunt him, he’s usually activating at a two-fer, at least. When I checked my hunter log afterwards, I saw four parks listed from him (a four-fer?).
At this point in the activation, I had gotten the ten QSO’s that I needed to call the park activated. I thought, let me try the VK160 on 60 meters. I re-tuned the KX3 and got five more fast QSO’s. The antenna worked great.
Before I packed up, I decided that I really wanted at least ten contacts on 160 meters, which was my original goal. I went back to 160 meters, now close to an hour later than when I began the activation, and easily added five more new QSO’s to the log. Maybe propagation had changed the later/darker it got or some new hams were on the band who weren’t on earlier, but I was satisfied to have gotten more than 10 on the top band.
The Results
Here’s how I did. Green pins are QSO’s on 160 meters, blue pins are 80 meters and the pink ones are 60 meters (click image to enlarge).
The “Top Band” activation was a success! The VK160 worked flawlessly, thank you Brian, K3ES for posting your design and providing the inspiration to activate on 160 meters.
My POTA “My Stats” page now shows 11 digital QSOs on 160 meters that I didn’t have before. I love conquering new challenges and given the challenge of going mobile with an antenna that will actually work and tune up on that low of a frequency at a park that won’t make you leave at sunset, well… that was quite an accomplishment!
Thank you to the 22 hunters (11 on 160 meters) who helped make it a success, including my friend Del, N2NWK in Washington, DC.
Fort Baker is a former U.S. Army post situated at the north of side of the Golden Gate, opposite Fort Point and adjacent the town of Sausalito, California. The post is now part of the sprawling Golden Gate National Recreation Area (GGNRA) which is also known as K-0647 for POTA.
Many of the good POTA spots in the GGNRA are heavily used for recreation and sightseeing on weekend days such as this, but Cavallo Point is out of the way enough that there was still ample, free parking today. This location offers spectacular views of the Golden Gate Bridge, the city of San Francisco, and Alcatraz and Angel Islands at anchor in San Francisco Bay.
Today the “pull of POTA” was strong as I wanted to get another activation done before the arrival of an anticipated solar storm as well as rains predicted for the coming week.
During the week leading up to this activation the Bay Area has experienced fine weather with mild daytime temperatures and light winds, but driving in, the sound of rigging slapping loudly against the aluminum masts of the sailboats docked in the Presidio Yacht Club marina told me that it was windy down here.
A short series of wooden staircases lead up from the parking area to Battery Yates, named for Captain George Yates of the U.S. Cavalry who fell in the Battle of Little Big Horn in 1876.
The gun battery is a reinforced concrete structure which once sported six rifles that fired a three inch caliber cartridge to provide for naval defense inside of San Francisco Bay. The guns were manned through the middle of World War Two when, by 1943, they had been moved to more strategic locations.
Today I had hoped to use the same steel pipe which supported a fiberglass mast and EFHW in an earlier activation from this spot, but unfortunately the pipe was too thick to get the jaw mount securely attached.
I went with plan B which was to use the pipe railing at the back edge of the gun pit. Being unsure whether or not the galvanized steel railing made any electrical connection to what surely must be rebar embedded in the concrete, I deployed the 17 foot vertical whip with three radials just in case.
Whatever was serving as a counterpoise, it was doing a great job, providing an SWR reading of 1.0 to 1 on the Mountaintopper MTR-4B. This was probably the third activation on this Lithium-Ion battery pack, so the power was down to 3.7 watts, still plenty for a CW activation with a resonant antenna.
The activation was scheduled ahead of time on the POTA web application so all I had to do was just start calling CQ POTA and let the RBN do the spotting. I soon heard from KG6HM from right across the Bay, followed by stations from Washington, Idaho, Utah, Arizona, and New Mexico.
I was starting to think it would be only western states calling in, but the band opened up a bit, bringing N3RT from Delaware. Now we had a proper coast-to-coast activation, and, I bagged a hard-to-get state needed for an informal CW “Worked-All-States” achievement.
By this time, the wind really started to pick up and with the sun so low in the western sky, it was becoming chilly. Satisfied with the 14 QSOs in the log, we packed up, made our way back down the pathway to the car, and then to a fancy coffee house in Sausalito for a nice warm cup.
I am catching up with field reports and videos from last month and, I must admit, it’s fun reliving these activations.
October was such a busy month, it’s all been a bit of a blur.
Because I have a second Thanksgiving meal to prepare this morning for my wife’s family, I need to keep this report short–which won’t be easy because there’s a lot to unpack here– so we’re going to attempt do another Postcard Field Report!

Part of the fun of the campout was hanging with my good friend Joshua (N5FY) whom many of you know from his amazing Tufteln antennas and accessories.
On the morning of Friday, October 13, 2023, Joshua and I activated Rocky Mountain (W4G/NG-011), a beautiful 10 point summit along the Appalachian Trail.
That afternoon, we met with Joshua’s family briefly, then planned to head to a pub in Clayton, Georgia, where a number of the W4 SOTA campers were gathering.
Joshua determined we had just enough time to pop by Don Carter State Park (K-2171) for a quick POTA activation and still make it to Clayton in time. As a bonus, Don Carter SP has a number of covered picnic shelters, making set up in the dry quite easy (it was raining at the time).
For this activation, I used my Mountain Topper MTR-3B field kit that I had used during my SOTA activation on Rocky Mountain. In fact, it was the only radio kit I brought with me for activations that day.
Joshua lent me his Tufteln 40/20 meter linked EFHW antenna (we only used the 20 meter portion of it) and I also got to use a few other accessories that were still very new to me:
N6ARA MiniSWR Meter
One was my friend Ara’s latest creation, the MiniSWR meter. Ara (N6ARA) kindly sent me this production unit to test (at no cost to me) earlier in October.
I was very excited about this particular product because a few of my QRP radios lack a built-in SWR meter (my MTR-3B, MTR-5B, TR-35, and SW-3B to name a few). Ara’s MiniSWR meter is so tiny, it’s easy to carry even in my MTR-3B SOTA kit that’s built into a Pelican 1060 waterproof case. (If you’d like more details, I’ll be adding this MTR-3B kit to the Radio Field Kit Gallery soon).

As with all of Ara’s products, the MiniSWR works brilliantly, is very affordable, and is available as a kit or pre-assembled. Check it out at N6ARA.com!
Being honest here: this battery sort of blows my mind!
When paired with super efficient QRP radios like my MTR-3B (which uses something like 18mA in receive), one charge will take me through as many as two or three full SOTA/POTA activations!
When I purchased these, I also bought two 3S packs in a Prime Day deal. These 9V batteries work so well, though, I’ve yet to add PowerPoles to the new 3S packs. I prefer the size and ease of use of these 9V cells.

I’m very fortunate in that in the past few years I’ve acquired a number of QRP radios that I use in rotation when I do park and summit activations.
As I mention in my “Getting To Know You” video below, my very first dedicated QRP field radio was the original Yaesu FT-817 (non-ND version), so it has a special place in my heart.
