On Friday, February 9, 2024, I had an opportunity to do an extended Late-Shift POTA activation in Pisgah National Forest. I couldn’t pass that up!
Once again, one of my daughters had a casting call and a Shakespeare performance that opened up an activation window from about 17:00 – 20:00 local (22:00 UTC – 01:00 UTC).
If you’ve followed my POTA activities for a while, you’ll note that multi-hour activation windows are very much a rarity. More often than not, I’m squeezing activations into 30-60 minute windows of time as I go about my work and family duties.
Pisgah National Forest and Game Lands
The closest POTA site, once again, was Pisgah National Forest (K-4510) and Pisgah Game Lands (K-6937). There are so many sites to choose from within Pisgah; it’s always a difficult decision in terms of picking a location.
In this case, I decided to stay a little closer to mobile phone service just in case my family needed to reach me during that time. I chose the Sycamore Flats picnic area and was happy to see that the picnic shelter was available.
I thought it might be fun to set up two antennas since I had so much time. For the first part of the activation, on 20 meters, I would deploy the Chameleon MPAS Lite vertical.
For the second part (the following UTC day), I would deploy my MM0OPX 40-meter end-fed half-wave as I knew 40 meters would be much more active after sunset.
EFHW Deployment
Since sunset was approaching, I deployed my MM0OPX EFHW first because it’s much easier to deploy a wire antenna in a tree when it’s still light outside.
Side note: I mention in the activation video that a good headlamp (like my Fenix) makes working in the dark quite easy. I’ve deployed wire antennas after sunset with headlamps before–it’s quite doable–but I still prefer using a throw line when there’s still sunlight. It’s just easier (for me, at least) to judge distance.
I deployed the EFHW in a tree and in the brush between two pathways. While it would have been easier to deploy it on a path, I always try to deploy my wire antennas in a way that hikers and other park guests wouldn’t easily walk into them–especially at dusk when even high-visibility line colors are difficult to see.
Chameleon Carbon Fiber Tripod
The second antenna deployment was my Chameleon MPAS Lite vertical, and this activation gave me an excuse to test the new Chameleon carbon fiber portable tripod.
In January, Chameleon sent me a box with a few of their smaller accessories/promotional items. I plan to give away everything, save the tripod, in an upcoming QRPer giveaway.
I’ve been eager to test the tripod because it’s lighter and easier to transport (in my SOTA pack) than the stainless spike that comes with the MPAS Lite antenna system. This tripod will also come in handy when operating at parks that don’t allow stakes in the ground. Continue reading POTA by Lantern Light: One Activation in Two Days with Two Antennas!→
It’s funny how sometimes one small accessory can have a huge impact on a field radio kit.
When I first learned about the Elecraft KH1 (basically, the day I was invited to join the volunteer testing group), I felt like Elecraft had designed my ideal QRP radio. The KH1 is super compact, weighs 13 oz completely loaded, covers my favorite bands, and has features I would expect in much pricier radios. It reminded me of my beloved KX1, but even more portable with more features.
The KH1 caters to handheld or pedestrian mobile operating–at least, that was the overarching design objective. It accomplishes this amazingly well. It’s so easy to operate handheld, and there’s nothing else quite like it on the market. I suspect that when others copy the design (I’m sure they’re already doing so–!) it won’t be as versatile, functional, and lightweight.
At the end of the day, though, I feel like I’m only using the KH1 pedestrian mobile about 30% of the time I have it on the air. Of that 30%, I’d say that only 10% of the time I’m pedestrian mobile while activating, and 20% of the time I’m doing little impromptu radio sessions in parking lots, ballparks, while visiting family, and even on my own mountain property.
While handheld operating is simply a game-changer, I knew I wouldn’t do this 100% of the time with the KH1. It’s for this reason that my very first bit of proper KH1 feedback to Elecraft, well before I had my hands on a prototype, was that a right-angle adapter for the whip antenna would truly round out the KH1’s field prowess.
This would basically give my KH1 the same functionality of my beloved KX2 and AX1 antenna combo, but in an even more portable package.
Turned out, Elecraft already had a right-angle adapter on the design board!
Fast-forward to present day…
Last week, Elecraft sent me a prototype of the right-angle adapter to test and evaluate. They’ve given it the model number KHRA1.
Full disclosure: Elecraft also gave me permission to post a video and article about this new accessory even though (at time of publishing) it’s not even showing up on their website. I will, however, link to it here as soon as Elecraft makes it available. This is an item I would otherwise have tested in private–thanks, Elecraft!
The KHRA1 is a simple adapter. Other than metal attachment hardware, most of it is lightweight and 3D-printed from a durable material (I assume the same material they use in the KH1).
Attaching it to the KH1 is very easy.
First, you unthread the large metal thumb nut from the KHRA1. You will need to hold together the remaining KHRA1 components (legs and attachment bracket) so that they don’t come apart before you attach them to the KH1. This is actually pretty easy to do, but users should know to follow the KHRA1 instruction sheet. If these parts fall apart in the field, it might require a bit of searching the ground for the pieces.
You simply thread the large thumb nut onto the KH1’s whip antenna antenna port, then thread the rest of the KHRA1 bracket/legs onto the large thumb nut.
Check out Elecraft’s illustration:
I then position the KHRA1 legs as shown above, then tighten the KHRA1 adapter so that everything is secure.
It’s super simple to do, and you can see this process in my activation video below.
Speaking of an activation…
On Saturday, March 2, 2024, (yes, only two days ago) I had my first small window of opportunity to squeeze in a POTA activation and test the KHRA1.
That day, my daughters and I had a number of errands to run, then a three-hour round-trip drive to pick up my wife. We were on a very tight schedule, but I had a 30-ish minute window of opportunity to fit in some POTA radio therapy.
I set my sights on the easiest-for-me-to-hit POTA site on the Blue Ridge Parkway: the Folk Art Center.
Amazingly, I discovered that morning, that the KHRA1 fits in my Pelican M40 Micro case along with my KH1, whip, counterpoise, key, spare N6ARA key, and earphones.
With the KHRA1, this means my M40 field kit can do both pedestrian mobile and tabletop operating. Woo hoo!
The weather that morning was simply glorious. A very wet front swept through the previous day leaving behind clear skies and warm temps. Frankly, it was a bit odd activating without wearing a jacket or hoodie.

Setting up was quick and easy, even though this was my first time using the KHRA1 in the field.
I hopped on the air and started calling CQ. Once spotted (for some reason the RBN auto-spotting feature wasn’t working again), the contacts started flowing in.
I worked a total of 18 contacts in 16 minutes. It hardly gets better than that for a CW activation!
I had to call QRT after my 18th contact. Even though I had a 30-minute window to POTA, nearly 14 minutes of that was taken up with my intro and summary for the activation video.
I called QRT with a small pileup still in place. I really hate doing that, but I had a schedule to keep!
QSO Map
Here’s what this five-watt activation with a 4′ telescoping whip antenna looked like when plotted out on a QSO Map:
Activation Video
Here’s my real-time, real-life video of the entire activation. As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.
The KH1 works amazingly well as a tabletop radio when combined with the KHRA1 adapter.
At the end of the day, the KHRA1 is a very simple piece of hardware, but it effectively transforms the KH1 from a handheld radio to a tabletop.
Of course, I’ve used the KH1 numerous times with wire antennas in a tabletop configuration (I’m a massive fan of wire antennas) but the ability to use the 4′ whip antenna and internal KH1 loading coils means that I can operate anywhere I have a surface.
Herein lies the thing I love about my KX2/AX1 pairing as well. It’s just with the KHRA1, the KH1 makes for an even smaller, lighter-weight field kit.
Any negatives? The only one I’ve come up with is that the KH1 is so lightweight that I realize I need to carry a small piece of shelf liner (something like this) to provide the KH1 with a bit more grip on a slick park table, especially those composite ones.
Again, I will update this post when Elecraft announces KHRA1 pricing and availability.
Thank you
I still can’t believe the entire kit fits in this small case. Even when I put the KHRA1 thumb screw on backwards!
Thank you for joining me on this quick little tabletop activation!
I hope you enjoyed the field report and my activation video as much as I enjoyed creating them!

I’ve been eager to take the 80-meter coil on a POTA activation because 1.) if it proved effective, it would be great to have such a low-impact, low-profile antenna for 80 meters, but 2.) it’s been very difficult to fit in an evening POTA activation with my family life.
It would have been difficult to gauge how effective an 80M antenna performs in the late morning or early afternoon when I typically activate local parks/summits.
On Wednesday, February 6, 2024, a two-hour window of opportunity opened. One of my daughters had a dress rehearsal that night, and I knew of a nice, quiet, secluded POTA spot only 25 minutes away.
Pisgah National Forest (K-4510) and Game Land (K-6937)
My original plan was to arrive at the Looking Glass Falls’ picnic area, deploy the antenna, fire up the stove, make some coffee, eat on-site, then begin my activation after the start of the UTC day.
So why wait for the new UTC day?
Mainly because once you hit the new UTC day, it counts as a new activation. That really works in your favor as an activator if your goal is to complete a valid activation (with ten contacts) and you’ve enough time to do that before the UTC rollover. If you time it all correctly, you could activate double the parks with a minimum of 20 contacts (split 10/10). In my case, that would mean a total of four parks activated in one evening (since this was a two-fer).
I decided fitting in an activation prior to the UTC rollover simply wasn’t worth the rush.
Once I arrived on-site, however, I was already changing my mind.
I started my activation video, deployed the MC-750, and looked at my watch. I had roughly 15 minutes before the UTC rollover.
It would be tight, but I decided to give it a go and try logging ten contacts before 18:59:59 local (or 23:59:59 UTC).
If I couldn’t log ten before the UTC day, who cares!? It would be a fun challenge for sure, but I wasn’t going to cry if I couldn’t gather enough contacts for a valid activation.
There was another factor, too: operating 80 meters with a 17′ loaded vertical isn’t exactly “efficient.” My theory, though? It doesn’t need to be efficient. It’s crazy portable, convenient, and as a POTA activator, I only need enough performance to get the job done.
Time to hit the air!

In late December 2023, I received a package from Jesse at JNCRadio/Chelegance. It was their new MC-599 portable dipole antenna. They sent it—full disclaimer: at no cost to me—for evaluation, but shortly after receiving it, life got crazy and I was delayed in taking it to the field.
Fast-forward to February, and I was eager to take it to the field and see how it might perform. On February 5, 2024, a nice window of opportunity opened in the afternoon while one of my daughters was rehearsing A Midsummer Night’s Dream with her cast. Pisgah National Forest and Game Land were a 20-minute drive from her meeting site, so I headed there to deploy this new antenna.
The JNCRADIO MC-599
On-site, I pulled out the two main components of the MC-599 dipole system: the bespoke padded bag holding the antenna and the portable mast.
I knew the basics about assembling the MC-599 because I had watched a video on the Chelegance website that morning.
However, this was the very first time I had deployed the MC-599. I had never even removed any of the antenna components from the padded bag.
With this antenna, it’s best to have an open area for the two sides of the dipole (two telescoping whips) to fully extend without touching tree branches, etc. I had one particular picnic site in mind at the roadside picnic area I chose, but a couple was having a picnic there when I arrived. I waited to see if they might be leaving soon, but they weren’t, so I chose a site I had used before, even though it was flanked by trees.
Assembly was easy: I simply attached the center of the dipole to the 13′ mast, then attached the two telescoping whips to either side and extended them to the 20M position silkscreened on the whip (identical to the MC-750 vertical markings—see below).
Next, you simply attach your coax to the center of the dipole, then extend the mast all the way up.
I had to avoid touching tree branches, but it actually fit quite easily into this small space.
Since it was a bit breezy, I used some line to guy the mast. Ideally, you’d want a minimum of three guying points, but I only had two lines with me, so I made do, and it worked fine—the antenna was stable.
Next, I set up my radio: the Yaesu FT-818ND. Since the MC-599 was, in theory, resonant, I didn’t need an ATU for a match.
I turned on the FT-818 and discovered that the SWR was a perfect 1:1. Amazing.
I suppose I shouldn’t have been surprised because my Chelegance MC-750 is always perfectly resonant (without needing a transformer) simply following the whip markings for guidance.
I should note here that the MC-599 can handle up to 200 Watts PEP—I was pushing 5-6 Watts. Also, the frequency range using the whips is from 20-6 meters. Chelegance also includes two 7 MHz wire elements that can be deployed in an inverted vee shape to play radio on the 40-meter band. It’s an efficient system and has many fewer components than a Buddipole systems I’ve used in the past.

Keep in mind that my POTA site was in a deep valley, flanked by high ridge lines–I wasn’t sure what to expect as I hopped on the air.
I started calling CQ POTA and the first station I heard was DL1OK operating in Spain as EA8/DL1OK. Logging Dmitrij was a good sign indeed for this portable dipole!
Stations kept flowing in. I worked my first ten contacts in ten minutes.
I continued working stations in a continuous pileup until I ran out of time. I ended up logging a total of 46 contact all within 50 minutes. I did spend a few extra minutes (as I always do) trying to pull out weak stations and slower code stations.
What fun!
QSO Map
Here’s what this five-watt activation looked like when plotted out on a QSO Map.
Note that this map does not include my contact with EA8/DL1OK in Spain:
Activation Video
Here’s my real-time, real-life video of the entire activation. As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.
I’ve got to admit: the MC-599 made a great first impression.
As with the MC-750, I’m most impressed with the build quality. The components are all sturdy and nicely machined. The padded case was custom made to hold the MC-599 and its components. Everything fits together as it should and—again—was resonant when deployed according to the whip markings.
Even on this inaugural deployment, it didn’t take long to set up. The next time I deploy it, it will go even faster. Packing it up afterward (as you can see in the video) went very quickly.
Keep in mind: the MC-599 is a low-impact, high-profile antenna.
If you’re at a site that doesn’t allow antennas in trees, the MC-599 could be an excellent option. Other than using optional guy lines that would require tent stakes in the ground, it would have no impact on park grounds.
I love the fact that the MC-599 is self-supporting. This would be an absolutely brilliant antenna to use at parks with wide-open spaces and few trees for support.
That said, it is not a stealthy antenna. In fact, portable dipole antennas are some of the most conspicuous portable antennas you could deploy. They’re maybe slightly less conspicuous than a hex beam or Yagi. Even though I was cloaked by a few trees, the couple that was occupying the picnic site I had hoped to use couldn’t help but stop by on their way out and ask what it was I was doing. I bet if I had been using a wire antenna, they wouldn’t have even seen it.
I would always ask permission before setting up an antenna like the MC-599 at, say, a small historic site or urban park.
I could also see using the MC-599 for SOTA (Summits On The Air), but primarily on summits that are either drive-up, or where the hike is minimal. The aluminum alloy mast is lightweight for its size, but it’s quite large to consider taking on an extended hike. However, for a nice drive-up summit, I imagine you could work some serious DX. Just bring a few guy lines in case it’s windy.
I do think the MC-599 would make for a great Field Day antenna. Since it can handle up to 200W PEP and is easy to lower and switch bands, it would be a brilliant portable option for those operating a multi-band 100W rig.
But obviously? It’s an exceptional performer with QRP power. It’s hard to beat a dipole even when it’s only 13′ off the ground.
Thank you
Thank you for joining me on this fun activation!

I woke up a little too early on the morning of Saturday, February 3, 2024.
The previous evening, we recorded a Ham Radio Workbench podcast episode with my dear friend Ara (N6ARA) as a guest. It was a load of fun, and we ran over time (no surprise there). Since we started recording at 18:00 Pacific Time, it means that it was 21:00 here in the Eastern time zone. By the time the episode ended, it was well after midnight my time.
For some reason, my body clock only allowed me to sleep for five hours, but I planned to sneak in a nap at some point during the day. Our plans were modest that Saturday (only to visit my father-in-law in the hospital), and I had no intention to fit in a POTA activation.
Around noon, my daughters asked if I’d drive them to watch one of their friends in a Shakespeare performance at 2:00 PM. We quickly sorted out plans, and I grabbed my GoRuck GR1 pack, which (due to a crazy January) had hardly been touched since my activation with Hazel nearly a month prior.
Pisgah National Forest (K-4510) and Game Land (K-6937)
As you’ll hear me mention in a number of my field reports, the venue where my daughters rehearse Shakespeare and perform is a short drive to Pisgah National Forest/Game Lands. In the past couple of months, I’ve enjoyed numerous activations in Pisgah.
The weather was perfect for playing radio outdoors. It was chilly, yes, but not so cold that I needed to wear gloves.
I was looking forward to putting the Elecraft KX1 on the air again. As I state near the end of my video below, it’s one of my all-time favorite QRP rigs.
My trusty GoRuck GR1
I decided to pair the KX1 with my KM4CFT end-fed half-wave that I built for 30 meters, with a linked 40-meter extension.
On this particular afternoon, I wanted to focus on 30 meters, so as I deployed the antenna, I unhooked the 40M link.

In truth, we’re not big fans of Myrtle Beach—we prefer more secluded, less commercial spots along the coastal Carolinas. In the summer, Myrtle Beach is jam-packed with visitors—the traffic is a little insane—but in the winter, Myrtle Beach is relatively quiet. Getting around is a breeze, and accommodation is easy to find.
This trip was all about family time, so I didn’t pre-plan a single activation, and I didn’t pack several radios. In fact, the only radio I brought was my Elecraft KH1, which lives in my everyday carry backpack.
The KH1 is a constant companion these days. It was really fun to take it on one of the balconies of our room and hunt parks and summits. Despite a little QRM, I was able to make a number of contacts just using the KH1 whip and dangling the counterpoise.
I remember working my friend Alan (W2AEW) while he was activating a park in New Jersey. I sent him the photo above. What fun!
Lewis Ocean Bay Heritage Preserve Wildlife Management Area (K-3903)
On Wednesday, December 20, 2023, we decided to spend part of the morning and afternoon in Conway, South Carolina, which is about a 30-minute drive from Myrtle Beach.
My wife asked, “Surely, there’s a park you can activate along the way?” (She and my daughters fully support my POTA addiction.)
After a quick glance at the POTA Map, I determined that indeed there was!
Lewis Ocean Bay Heritage Preserve WMA was essentially on the way to Conway, and I could tell based on a quick Google Map search that one of the access points (a huge gravel parking lot) was conveniently located next to the highway. Score!
I grabbed my backpack and camera (of course I brought along the camera just in case!). We drove 25 minutes to the access point which was easy to find.
As luck would have it, as I parked, I noticed that a motor grader was resurfacing part of the parking lot and the main WMA access road. This wouldn’t affect my activation, of course, but it was incredibly loud—especially the constant back-up alert.
So that my KH1 audio would be audible over the grader noise and the highway noise, I connected it to my Zoom H1N recorder.
Setup was quick despite setting up the audio feed and arranging the camera position under the shade the open hatch of my Subaru provided.

On Thursday, February 1, 2024, I managed my first POTA activation in weeks.
As I mentioned here on QRPer, January was a crazy month. Not only did I lack the time to activate parks, but I also wasn’t in the right frame of mind to make activation videos.
However, on February 1, things were looking up, and a nice little POTA activation was just what the doctor ordered!
I grabbed my KX2/AX1 pack as I headed out the door.
On the way into Asheville, I stopped by the Folk Art Center on the Blue Ridge Parkway (K-3378)–my go-to site for convenient activations. I had a one-hour window of time to fit in an activation.
BRP & MST Two-Fer
You might recall that in my last field report (from January 5, 2024), Hazel and I hiked the Mountains-to-Sea Trail (K-8313) and found a trailside spot that was also within the Blue Ridge Parkway (K-3378) property boundary. The activation counted as a two-fer!
You don’t have to hike the Mountains-to-Sea Trail (MST), however, in order to activate it and the parkway at the same time.
In the activation video, below, I show where one of the picnic tables at the Folk Art Center is close enough to where the MST passes that it counts. Makes for an easy drive-up, two-fer activation.
New Tufteln Cover!
A few weeks ago, my friend Joshua (N5FY) sent me a new protective cover for my Elecraft KX2. He’s now made these covers a part of his product line at Tufteln.com.
Like my Tufteln KX1 cover, the KX2 cover locks onto the front of the radio with rare earth magnets. It only requires that you replace the stock screws around the KX2 display with the ones Joshua provides. His replacement screws have a slightly higher profile, which allows the cover to attach magnetically.
What I love about Joshua’s covers is that they do a brilliant job of protecting all of the controls of the KX2 without taking up as much space as, say, the stock clear cover that came with my side panels.
Also, it fits the KX2 perfectly whether you have side panels or not!
Setting up
Of course, the glory of the KX2/AX1 combo is that it takes almost no time to set up in the field.
Within a minute or two, my gear was deployed, and I was on the air seeking a clear frequency.
I opted to use my Begali Traveler (over my KXPD2) key since it was also packed in my GoRuck GR1.

On Friday, January 5, 2024, I looked at Hazel and could tell that, despite the chilly temps, she wanted to go on a late afternoon hike. I did, too, for that matter and why not combine the hike with a POTA activation?
In addition, we were expecting a winter storm to move in that night, so hitting the trail in advance of the snow and ice seemed to make sense.
Before I could get my boots on, Hazel was waiting by the car door to jump in.
At 1175 miles long, the MST stretches from the Outer Banks of North Carolina to the Great Smoky Mountains (see map above).
I can actually hike to the MST from my QTH, but it takes a good hour and half to do so. It’s much easier to drive to one of the numerous nearby trailheads, and that’s exactly what Hazel and I did. I drove to one of my favorite Blue Ridge Parkway POTA spots where a short manway connects to the MST.
Hazel was so excited to hit the trail. (I was, too.)
At the end of the day (because, it was nearing the end of the day) we couldn’t hike for long if I planned to also complete a POTA activation. Sunset was at 5:29 PM local and I didn’t want to pack up and hike back in the dark.
I started my action camera and captured the last bit of hike before Hazel and I found a great spot to set up. There were enough trees around to deploy a 40 meter EFHW and a relatively flat spot to set up my Helinox chair and KX1 station.
Since much of this section of the MST is on the Blue Ridge Parkway grounds, I checked quickly to make sure my operating site would qualify as a two-fer with K-3378.
I opened the Parceled App on my iPhone to confirm that my site was indeed on Blue Ridge Parkway property..
It’s been a stormy past several days here in Northern California, but if anything, the weather only amplifies my motivation to go outside and get on the air.
Rather than do a separate writeup for each, this post is a roundup of my last four POTA activations, from Friday, February 2nd through Sunday, the 4th.
A faint rainbow splashes down in front of Angel Island
Thursday and Friday had been wet, with one storm in a series moving across the Bay Area. However, by Friday evening the cold front had passed and there was a break in the rain. This was a perfect opportunity to try an after work activation at the Presidio of SF (K-7889).
I hadn’t used the QCX-Mini in a while, and this activation reminded me why. I believe what is happening is that being so close to the antenna, RF interference causes clicking while keying, nearly to the point of distraction. I need to experiment with RF chokes on the key and audio lines to see if that improves the situation.
Fed up with the RFI on the QCX-Mini, I switched over to the MTR-4B which doesn’t seem to suffer the same issue. I wrapped up the activation after netting 21 QSOs in the cold west wind.
The next bout of rain wasn’t due to arrive until later Saturday afternoon. This was a change in the forecast that subsequently altered my plan to stay in Saturday soldering on my QMX Hi-Bander project.
Initially I went to Fort Point (K-0819) in the hopes of changing it up from my usual activation park but there were just too many people there. So seeking relief from crowds, I crossed the Golden Gate Bridge and went up on the slopes of Mt. Tamalpais.
I parked at Trojan Point at an elevation of approximately 1800 feet. See this post for more views from this location. The temperature was in the mid-40s, which is cold for us coastal Californians. Besides, the winds were picking up ahead of the next storm so I operated from the comfort of my vehicle using the Gabil 7350T base loaded vertical antenna on 15m and 20m.
This activation used the FT-818 and yielded 23 contacts, including JH1MXV from northwest of Tokyo, Japan coming in fairly strong on 21 MHz.
Driving back to San Francisco takes me right through the Presidio of SF (K-7889) and noticing that it was after 00:00 UTC, I made the last second decision to divert to East Beach to see if I could work in another activation before the anticipated rain.
At my usual spot for activating this park, it took only moments to raise the MFJ-1979 20m quarter wave and do a quick deployment of the MTR-4B on the trunk of the car. The wind was picking up, but not nearly as strong as it was up on the mountain.
After seven QSOs, the skies began spitting raindrops, this was going to be close! I closed the cover of the Maxpedition pouch to protect the radio and battery while the Bencher paddles could tolerate a little bit of moisture.
If 2014 Thomas looked at 2024 Thomas’ QRP radio inventory, he wouldn’t believe the number of radios he’d accumulated in a mere decade.
It’s a little insane, really.
The thing is, over the years, I’ve picked up some great QRP bargains at local hamfests and via various online classifieds. While it’s not exactly “chump change,” you can often find good used QRP radios for less than $300.
Sometimes it’s hard (for me) to pass up those deals.
One such deal was a local fellow who wanted to sell his Ten-Tec R4020 a few years ago. He listed it for $125, and there weren’t any takers for a few days. (Keep in mind, this was a wee bit before our current CW Renaissance.)
I contacted him and snapped it up. I thought the R4020 might be a fun little two-band radio for POTA and SOTA adventures.
I was right!
The R4020 is an incredibly fun radio to use in the field.
The audio is superb. It has a low noise floor, great sensitivity, and a well chosen filter width. What the R4020 lacks in features, it makes up for with audio fidelity, in my opinion.
I look forward to each and every activation with this QRP wonder.
Speaking of which…
Tuttle Educational State Forest (K-4861)
On Wednesday, January 3, 2024, I made some time in the afternoon to stop at Tuttle Educational State Forest.
I believe I was on the way back to the QTH that afternoon after an overnight with my folks in Hickory, NC.
I love Tuttle, but it had been a while since I completed an activation here. In the activation video (below) I said it had been a couple of months, but later I checked and realized it had been four months! Wow! Hard for me to believe it had been that long!
That day, the park was void of visitors. I was the only person in the parking lot. No surprise here: kids were just heading back to school after a long Christmas break, so there were no field trips on site.
Since there was no competition in the picnic area, I decided to grab a site I might not have actually used before in previous Tuttle activations. I’m evidently working on my WATPT (Worked All Tuttle Picnic Tables) award!
First, a quick inventory…
Before heading to Hickory the previous day, I grabbed the little Blue Ridge Outdoors pouch that held my R4020 and much of the supplies I’d need to get on the air.
I knew, though, that this wasn’t a fully self-contained field kit. Not yet, at least. I hoped that between my main radio gear pack and what I had in the car, I could piece together an entire station.
In my activation video, I speak to the mental checklist I use to make sure I have all of the necessary components to complete my field kit. I did this on site as I set up (typically, this is done prior to leaving the QTH).
Fortunately, I had everything I needed, including an external speaker.
Side note: Some of you might notice the (disproportionately) large Bioenno battery I used during this activation. Yes, it’s crazy overkill for this wee QRP radio. I’d normally use a 3Ah battery, but frankly, I need to exercise my 15Ah battery from time-to-time, too! It gets the least amount of field time because I normally save it for my QRO radios that I use so little in the field.

On Friday, February 9, 2024, I had an opportunity to do an extended Late-Shift POTA activation in Pisgah National Forest. I couldn’t pass that up!
The closest POTA site, once again, was Pisgah National Forest (K-4510) and Pisgah Game Lands (K-6937). There are so many sites to choose from within Pisgah; it’s always a difficult decision in terms of picking a location.
Since sunset was approaching, I deployed my MM0OPX EFHW first because it’s much easier to deploy a wire antenna in a tree when it’s still light outside.
The second antenna deployment was my Chameleon MPAS Lite vertical, and this activation gave me an excuse to test the new Chameleon carbon fiber portable tripod.
