On Friday, February 10, 2023, I had a hankering to fit in a POTA activation that morning. South Mountains State Park was an easy detour on my drive back to the QTH, so I scheduled an activation.
Brooks has been steadily working on his CW skills and is dangerously close to doing his first CW activation. We’ve managed to set up one late evening casual CW rag chew and I think his CW chops are very good. We plan to do more evening rag chews when our schedules align. He’s made amazing progress.
I contacted Brooks that Friday morning and he was game to meet up and do some POTA. He wasn’t quite ready to do a CW activation, so I suggested he log for me using the HAMRS app on my iPhone. I find that logging for CW ops during past Field Days really helped build my own confidence before I started using CW daily.
Brooks was 100% game to log for me.
And let me just say what a luxury it is to have someone log to HAMRS for me on my iPhone! It frees up my brain to simply log on paper (which I always do) and enjoy working stations without the extra busy work! Hat tip to good ole’ Brooks.
South Mountains State Park (K-2753)
I arrived at South Mountains State Park (the Clear Creek Access), put on my hiking boots, then Brooks pulled into the parking lot only a few minutes later.
We agreed in advance to fit in a quick hike up the Clear Creek Trail prior to the activation. I, for one, really needed to stretch my legs!
After the hike, I grabbed some gear from the car and we set up at the one picnic table at the Clear Creek Access.
Brooks and I both had commitments that day so could only play radio for 45-60 minutes max including set-up and take-down.
I deployed the same antenna I’d used the previous day: MW0SAW’s homebrew EFHW on a SOTAbeams winder.
You might have noticed that I’ve been taking the Elecraft AX1 antenna out quite a lot recently. At time of posting, I’ve almost used it for a month’s worth of activations.
In December, I thought it might be fun to only use the AX1 for one 2023 calendar month–say, the month of March–but since I evaluate and review radios and antennas, it’s just not realistic to make that kind of commitment.
That said, I did decide to simply start using the AX1 as my primary field antenna for roughly a 30-ish day period and, so far, that’s working out very nicely. I thought it might give some real-world context and usage for those who still believe I’ve just been lucky the days I use the AX1 in the field. No better way to test that theory than to just do it!
Mini rove!
It’s been a while since I’ve had time to do a proper park rove. I hope to do a five park rove within the next month or so, if I can clear out space in the schedule. I find roves so much fun and a nice change of pace.
On Saturday, January 21, 2023, on the way back to my QTH in the mountains of WNC, I had just enough time to activate two parks in short order. Having just been challenged by a short activation window at the Vance Birthplace (which, turned into a normal length activation due to a schedule change in my favor) I thought it might be fun to once again, show the whole KX2/AX1 set-up and pack-up process in my activation video.
South Mountains State Park (K-2753)
I chose South Mountains State Park as my first stop.
South Mountains has a number of public access points. I decided to drive to the main park entrance and set up at the equestrian picnic area. Choosing the main park entrance added about 15 minutes to my overall driving time; the Clear Creek access would have been quicker, but I’d been there only recently.

Friday, January 6, 2023, was a beautiful day and my route took me within 10 minutes of South Mountains State Park (K-2753).
Of course, I had to activate it!
In truth, I had only a short window to do the activation, but I knew it would be seriously fun.
I’d packed my Penntek TR-45L and Chelegance MC-750 for the trip and was looking forward to pairing the two.
My TR-45L actually has the built-in Z-Match manual antenna tuner, but I wanted to, once again, configure the MC-750 as a resonant antenna (much like I did in my previous activation).
I also had my new VK3IL pressure paddle along for the ride and wanted to see how nicely it might work with the TR-45L.
If I’m being honest, it was a bit strange not to use a wire antenna at this particular park because South Mountains has some very large old-growth trees that are ideal for hanging antennas.
You see, I did something I’d never suggest others do: in a moment of boredom, I casually cruised the classifieds listings found on QTH.com.
One of the very first listings was for a TEN-TEC R4020 CW QRP transceiver. The price, if memory serves, was $120 (+/- $10) shipped.

Without even thinking, I sent a message to the seller:
“I’ll buy it if it’s still available!“
He responded noting I was the first to reply to the ad, so it was mine if I wanted it.
I did, of course.
The R4020 arrived that same week, I opened the box, applied power to confirmed it powered up, then placed it on the top shelf in my shack.
At the time, I had a mountain of review and evaluations in process along with several articles in the pipeline for TSM and one for RadCom, and simply didn’t have time to properly explore the R4020. I thought it might be fun saving it as a little reward for meeting my deadlines.
Then, frankly, I just forgot about the R4020. This spring was a very busy time for me family-wise, then I spent the summer in Canada, and most of this fall has been all about catching up after having spent the summer in Canada. Funny how that works!
Fast-forward to November 11th, 2022 when I was packing a field radio kit to take on an overnight trip and I noticed the R4020 on the top shelf! My reward, finally–!
I quickly packed the R4020 in my Spec-Ops Order Pouch along with a 3Ah Bioenno LiFePo4 battery and a power cable.
South Mountains State Park (K-2753)
On Saturday, November 12, 2022, I jumped in the car and headed to South Mountains State Park with the R4020.
This past year, I’ve mostly set up at South Mountain’s Clear Creek Access on the west side of the park, but this time I decided to make my way to the equestrian picnic area near the main entrance and ranger station.
On Monday, September 12, 2022, I had one primary objective in mind: to test the Eton Elite Satellite portable shortwave radio.
Many of you know that besides being a QRPer, I’m also an SWL or shortwave listener. Over on my other blog, the SWLing Post, we post news, information, guest posts, and reviews covering the diverse world of shortwave radio and international broadcasting.
Occasionally, I evaluate new receivers and the Eton Elite Satellit is the latest shortwave portable from the Eton Corporation. It was meant to be their flagship, benchmark portable but unfortunately early production units were plagued with a bit of internally-generated noise. On September 12, I was trying to sort out just how much this internal QRM affected the radio’s performance.
South Mountains State Park (K-2753)
I wanted to go to a known RF-quiet area to check the Elite Satellit and the South Mountains State Park Clear Creek Access was an easy detour during my errands that day.
The Elite Satellit
First thing I did after arriving on site was to put the Elite Satellit through some basic paces (AM/SSB, Mediumwave, Shortwave, FM, AIR, etc.). I also compared it with the Tecsun PL-990 portable.
I made a long list of notes and observations to send to Eton that afternoon.
After I finished the tests, I checked my watch and–woo hoo!–I had just enough time to squeeze in a short activation. I only had a 45 minute window, so this activation needed to be a very quick one.
I had two radio kits with me: The Mountain Topper MTR-3B kit, and the Elecraft KX1 kit. I chose the Elecraft KX1 because I had such a blast using it the previous day at Lake James.
I had a number of antennas in my pack, but chose the excellent PackTenna Mini End-Fed Half Wave that I cut for 20 meters. This is one of my go-to SOTA antennas since it’s compact, rugged, efficient, and easy to deploy even if your only option is a short tree or telescoping mast as is often the case on a summit.
I felt like 20 meters would be a worthy band for the time of day and recent propagation trends as well. Hopefully, it would be productive enough to provide the 10 needed contacts to validate the activation. If I needed, I could use it on 30 meters with either its internal ATU or (more likely) the Elecraft T1 that was also along for the ride.
Turns out, if you go to Canada for nearly two months, when you return home you’re going to have about two months worth of catch up.
It’s all explained in one of Einstein’s theories. If memory serves, Einstein stated:
“One cannot simply ignore stuff for two months and expect no repercussions. Time lost must be accounted for due to the principles of the conservation of energy. Plus…what in creation were you thinking?”
When we returned from Canada in early August I had some pretty big plans about the parks and (especially) summits I would hit here in North Carolina. But after returning, I quickly realized I had so much work to do around the house and a number of DIY jobs I’d postponed at our investment property. They all immediately took priority.
Indeed, in the one month span after returning from Canada, I only performed three park and no summit activations. There was a three week period of time without activations of any sort. I simply didn’t have the time to fit anymore in my schedule. This all gave me a serious case of activation withdrawal.
If you’ve been following my field reports, you’ve no doubt noticed that I never do multi-hour activations at one site unless I happen to be camping at a POTA park.
I’m asked about this fairly regularly (why I don’t do longer activations to achieve Kilo awards, etc.) but the truth is I make POTA/SOTA fit in my busy family schedule. This often equates to short (30-60 minute) activation windows.
Then quite often, I’m on the road or doing errands in town and realize I have a short opening for an activation, so I squeeze it into the day. This is why I always have a fully self-contained field radio kit in my car. At a moment’s notice, I can set up a station, and play radio.
In a way, I find this style of quick activation fun, too. “Can I seriously validate a park during this short window of time–?”
These activations remind me of that scene in A Christmas Story where the father gets a small thrill out of timing himself as he changes a flat tire on the side of the road. I totally get that.
Except with me it’s deploying antennas instead of managing lug nuts.
Hamfest time!
Friday, September 2, 2022 was a big day for me. On the way back from visiting my folks that morning, I spent a couple of hours at the Shelby Hamfest.
The Shelby Hamfest typically has the largest outdoor tailgate market in all of North Carolina and likely one of the larger ones in the southeast US. I had no items on my wish list, I just wanted to see what was there.
This was the first hamfest I’d attended in a little over a year. It was a lot of fun and I got to meet a number of friends and readers/subscribers.
Driving home after the Shelby Hamfest that early afternoon, I realized I was passing dangerously close to the Clear Creek access of South Mountains State Park.
I had a couple of errands to run back home before the post office closed at 17:00 that day, but in my head I believe I had just enough time for a quick activation. The total amount of detour driving would only be about 15 minutes; I’d just need to keep the activation (including most set up and pack up) under 45 minutes or so.
At the last minute, I took a right turn and headed to the park!
Fortunately, the one lonely picnic table at the Clear Creek access was unoccupied.
I grabbed my IC-705 kit and a new antenna!
The MM0OPX QRP End-Fed Half-Wave (EFHW)
A few weeks prior, Colin (MM0OPX) reached out to me and asked if I would consider testing a new high-quality, highly-efficient QRP EFHW he’d designed.
Of course, there’s nothing new about an EFHW–it’s one of the most popular field antenna designs on the planet–but Colin’s goal was to make one with the lowest insertion loss possible in a compact, lightweight (50g), and durable format.
I say he succeeded.
In fact, this activation was actually the second one where I used Colin’s QRP EFHW. The previous day, I paired it with a then very Beta version of the Penntek TR-45L at Tuttle Educational State Forest (K-4861).
In short, the antenna made for a wildly successful QRP activation. Here’s the QSO Map (you’ll need to click and enlarge to see the number of contacts):
QSO Map from the previous day with the MM0OPX QRP EFHW
The Penntek TR-45L was still quite new at the time and even though I got John’s (WA3RNC) blessing, I didn’t post the activation video and mini overview on YouTube. Keep in mind the TR-45L was still in Beta so not all features had been finalized.
As I mentioned in a previous post, I’ve now invested in a Pro account with Vimeo that allows me to post completely ad-free videos that my Patreon supporters can enjoy and even download. I recently discovered that YouTube unfortunately inserts ads even though I have monetization turned off. I pay for Vimeo’s bandwidth and server space, so I also can control the ad experience completely (basically eliminating any possibility of ads!).
My Patreon supporters are the ones making it possible for me to pay the annual $420 fee to Vimeo and I am incredibly grateful, so I pass along the benefit to them.
The entire time I was in Canada this summer–about two months–I used two field transceivers: the Elecraft KX2 and the Discovery TX-500.
I did sneak in two extra radios under the floor of my trunk/boot space, but they both were limited to three watts and conditions were so rough during many of my activations, I wanted the option of a QRP “Full Gallon” (5 watts). Thus, I stuck with the TX-500 and KX2 (which are both actually capable of 10 watts output).
When I got back to the States, I was eager to do a POTA activations with my other radios–many of you know I like to rotate them–but there was one, in particular, I was eager to put back on the air…
The Mountain Topper MTR-4B.
This MTR-4B V2 is on loan to me from a very generous reader/subscriber. In fact, get this: he ordered the MTR-4B early this year and had it drop-shipped to me directly from LnR Precision. He knew I’d be in Canada for the summer, so has been incredibly flexible with the loan period (basically leaving it open ended).
My review of the MTR-4B will be published in the November or December (2022) issue of The Spectrum Monitor magazine. Then I’ll be sending the MTR-4B to its rightful owner!
In the meantime, I built an ultra- compact field radio kit around the MTR-4B and in my Tom Bihn HLT2 EDC pouch.
This kit is nearly identical to the one I made for my MTR-3B (just a different color, really).
It contains the radio, a battery, an antenna (although I used a different one during this activation), fused power cord, paddles, earphones, RF choke, RG-316, logbook, pencil, and even a full throw line and weight. I’ve listed all of the components with links below.
It’s hard to believe it all fits in such a compact kit and it works so well. It’s nice to know that with the kit it in my backpack, I’ve got everything I need to play SOTA or POTA at the drop of a hat.
South Mountains State Park (K-2753)
On August 8, 2022, I drove to my hometown to check in on my parents. I didn’t have a lot of time, but I wanted to fit in a quick activation with the MTR-4B along the way.
One of the easiest parks for me to hit en route is the South Mountains State Park Clear Creek Access–it’s maybe a 10-15 minute detour off of Interstate 40.
The weather was amazing that day, although I’ll admit I had to get used to the heat and humidity after spending so much time in Canada this summer!
This access point of South Mountains only has one picnic table. I’m always prepared with a folding chair if that table is occupied, but so far it’s always been available. I’m sure the reason is because this particular South Mountains access point is way less popular than the main entrances. Most of the visitors here come to fish at the reservoir.
Setting up
The great thing about having your whole station in a pouch is that setup is quick and easy.
As I mentioned in a previous post, I’m starting to sort out the gear I’ll take on a long road trip this summer. I still haven’t quite decided which radio will accompany my Elecraft KX2, but the lab599 Discovery TX-500 is on my very short list.
I pulled the TX-500 yesterday to do a firmware update and found my logbook for an activation I made on February 16, 2022. For the life of me, I couldn’t remember writing the field report for that activation.
I checked my YouTube channel and, sure enough, buried at the bottom of my video list was the activation video marked as “unlisted.”
That bit of time between mid-February and mid-March was crazy for me. I was in isolation for a week (thanks Covid) and had a very hectic family schedule. I accumulated a small backlog of videos then and this one was lost simply lost in the shuffle.
Here’s the report and video from that activation:
Clear Creek Trail
It was Wednesday, February 16, 2022, and I was driving to my parents’ house to help them with a few projects. I had enough time to make a little detour to the Clear Creek Access of South Mountains State Park (K02753) and had two things in mind: a good hike and trailside activation.
The weather? Man oh man was it was fickle.
On the interstate, I got caught in a proper downpour and traffic slowed to a crawl.
I thought about throwing in the towel then, but I made a promise to myself that I would continue driving to the park if it wasn’t raining when I approached the park exit on the interstate.
The (tr)uSDX has been a much-anticipated QRP transceiver for those of us who love playing radio in the field.
What’s not to love? It sports:
Up to 5 watts output power
CW, SSB, FM, and AM modes
A built-in microphone
Five bands: 80, 60, 40, 30, and 20 meters
A super compact and lightweight form factor
An open-source hardware and software design
Super low current consumption in receive
A super low price of roughly $89 US in kit form and $143 US factory assembled (via AliExpress, but there are numerous other group buys and retailers)
Frankly speaking, this sort of feature set in such an affordable package is truly a game-changer. Back when I was first licensed in 1997, I could have never imagined a day when a general coverage QRP transceiver could be purchased for under $150 US. The price is almost unbelievable.
My initial impressions
On Wednesday, March 30, 2022, I took the (tr)uSDX to the field to attempt a Parks On The Air (POTA) activation. I had only taken delivery of the (tr)uSDX about 15 hours beforehand and had only had it powered up for a total of 30 minutes the previous day. Most of that time, in fact, was checking the power output at various voltage settings into a dummy load. I did make one totally random SSB POTA contact shortly after hooking the radio up to my QTH antenna.
I knew that taking the (tr)uSDX to the field and making an activation video might not be the best idea having had so little time to play with the radio and get to know it in advance, but then again, I was simply too eager to see how it might perform. That and I always believe there’s value in sharing first experiences with a radio. Continue reading Video: Taking the new (tr)uSDX QRP transceiver on a CW POTA activation!→
A few months ago, Mike (KE8PTX), contacted me with info regarding his latest 3D-printed creation: a compact housing for an end-fed half-wave balun.
Mike’s 3D drawing
He called it the “Oreo Balun.”
Once printed, and after he wound the coil and installed the BNC, he sent this photo:
It’s cute, isn’t it?
He then surprised me by putting it in a padded envelope and sending it to me as a gift. Wow–thanks, Mike!
Oreo plans
End-Fed Half-Wave antennas are popular portable antennas for a reason: they’re effective!
They’re compact, easy to deploy, and resonant.
I only needed to attach some wire to the Oreo Balun, trim it, and hit the field!
Earlier this year, my buddy Vlado and I built two doublets with some scrap wire I had in my antenna parts box. I measured the amount of wire I had left from that same spool. I knew it wasn’t enough length for a 40 meter EFHW, but I did think there was enough for 30 meters.
After giving it a bit of thought, I liked the idea of having a dedicated 30 meter EFHW. For one thing, 30 meters is a great band for field deployments and in the past this band has saved my bacon when either 40 meters or 20 meters was wiped out. Thirty meters is also a refuge WARC band during contest weekends. In addition, a 30 meter EFHW is short enough that it could be deployed on most SOTA summits (which often have shorter trees).
Fortunately, I had just enough wire for 30 meters. IN fact, after trimming the antenna, I only had about two feet of wire to spare. It’s as if I had planned it! I would have never guessed that spool of scrap wire would have made two doublets and one 30 meter EFHW.

On Friday, February 10, 2023, I had a hankering to fit in a POTA activation that morning. South Mountains State Park was an easy detour on my drive back to the QTH, so I scheduled an activation.
