Mike is a massive fan of the SOTAbeams Carbon 6 telescoping pole and has been through two of them over the years he’s been doing field radio work. He told me that the new Explorer POTA20 is even better than the Carbon 6.
I don’t think Mike knows it yet, but after his recommendation, I ordered an Explorer mast—it’s backordered, so it’ll be a month or two before it ships.
Mike took this photo of his mast from a POTA activation this morning. You can see the mast left of the dead tree.
Mike is also a brilliant designer and has made a 3D-printed tent stake holder that fits on the end of both of these poles. He told me that these 20′ carbon fiber masts are so lightweight that there’s no need for guying the pole, even in fairly windy conditions. His simple tent spike is all that’s needed to hold a carbon fiber mast in place.

In the following video, Mike compares the Carbon 6 with the new Explorer mast and speaks to the utility of using a tent spike to secure the mast:
Thank you, Mike, for sharing this video and the tip about the new Explorer mast!
This morning, I’m still at our hotel in Dayton, Ohio, but about to pack up and head out. Eric (WD8RIF), Miles (KD8KNC), and I are heading for a day at the Armstrong Aerospace Museum, then, hopefully, a POTA activation on the way back to Athens, Ohio, where I’ll spend the night.
Tuesday morning, I’ll be up early and hit the road for North Carolina. Really looking forward to seeing my wife, daughters, and Hazel.
I thought I’d share a very brief POTA activation I enjoyed yesterday with friends.
Pater State Wildlife Area (US-9492)
Yesterday morning (May 19, 2024), Eric, Miles and I met up with Kyle (AA0Z), Brian (K3ES), Joshua (N5FY), and Charlie (NJ7V) at our hotel.
Eric, Miles, Brian, and I had planned to activate a park in nearby Indiana that afternoon, as Brian and I had never activated in that state. Joshua, Charlie, and Kyle were planning to join us on an activation in southwest Ohio en route. Unfortunately, Joshua was driving back to his home in Georgia, and Kyle was dropping off Charlie at the airport on his way home, so they couldn’t join us in Indiana.
Eric’s first POTA activation with his Elecraft KH1!
We arrived on-site a little after 10:00 AM local. Eric immediately set up his Elecraft KH1 in desktop mode using his new Tufteln KH1 Right-Angle adapter.
Brian set up under a tree with his Elecraft KX2 and a Tufteln random wire antenna.
The amazing Brian (K3ES)
I grabbed my Elecraft KH1 and we coordinated frequencies. Brian took 30 meters, Eric took 40 meters, and I took 17 meters (thinking either Joshua or Eric might move to 20 meters).
This was another instance where having a fully handheld, pedestrian mobile station truly offered a level of activation freedom.
The bands were in rough shape, but I kept my KH1 in hand and walked around the entire site with the CW Message memory sending out my “CQ POTA DE K4SWL.”
Over the course of 13 minutes, I worked five stations. All the while, I was holding the KH1, chatting with my friends, and petting a sweet local dog that instantly made friends with us.
This pup was a hoot!
This activation also gave me an excuse to try out the new Tufteln KH1 Antenna Angle Adapter which makes it a breeze to keep the antenna nearly vertical while holding the KH1 at a more comfortable angle. Thanks, Joshua!
Eventually, I moved to 20 meters and we all started working each other to help with our QSO count and to simply get each other in the logs. I logged two more stations, plus Charlie, Brian, and Joshua to make my 10.
Kyle (AA0Z) and his brilliant Toyota Tacoma POTA machine.
The idea was to hop off the air quickly so that Kyle and Charlie could use Kyle’s KX3 station to activate the park as well.
L to R: Kyle, Joshua and Charlie
Conditions deteriorated further, so we did rely on a few P2Ps with each other to help Charlie and Kyle finish and hit the road.

Here’s my QSO Map, but keep in mind that several of the pins are incorrect as Charlie, Kyle, Brian, and Joshua were all on-site:
All in all, we had an amazing time and it was a nice, relaxed way to wind down after an incredibly active 2024 Hamvention and FDIM conference.
Joshua working us P2P with his KH1 and the the most compromised–yet completely effective–antenna of all: a dummy load!
I will report more on Hamvention and share a few photos later this week.
For now, I need to wrap up this post and hit the road! There’s an aviation museum and POTA in my future today!
Heartfelt Thank You
I will add this one extra note: I’m simply overwhelmed with the kind comments and conversations I had with so many of you who took the time to catch up with me these past few days. Thank you so much!
Many thanks to Don (W7SSB) who shares the following spreadsheet that highlights the key similarities and differences between the Xiegu X6100 and the new Xiegu X6200.
A reader reached out to me this morning asking about the Mountain Topper MTR-3B. It reminded me of a teaser LnR Precision posted earlier this month in an MTR-4B update on their website. Here’s what they said:
Update: 4/1/23: We do not have MTR4 V2.3 available for purchase now but will be releasing more for purchase on May 1, 2024.
Apologies on the delay but we needed more time to get parts that are in short supply and fabricate. This will be the only and last offering of the MTR4b V2.3 radios as we are shifting focus on a redesigned and re-engineered version of the popular MTR3B!
It is our hope to have these out in Fall of 2024 if possible, but no guarantees.
I’m very excited about this news! I own two MTR-3Bs and absolutely love this model. When I checked in with LnR a couple of years ago, they said they had no plans to produce the MTR-3B again. They must have noticed the strong customer demand.
I assume the new model might incorporate some of the upgrades found on the MTR-4B, like an SWR and Power Output meter and a more accessible sidetone control. We’ll have to wait and see!
LnR is a small “mom-and-pop” company, so we’ll need to be patient as they introduce the new MTR-3B. I’m sure they’ll struggle to keep up with demand. I, for one, am eager to see this super-compact transceiver back on the market.
Many thanks to Mike (N2HTT) who recently reached out:
Hi Tom,
I recently treated myself to a Penntek TR-45L, and I think it’s the perfect field CW rig, except for one thing: the viewing angle sitting on a table is too vertical.
I made myself a tilt cradle that holds the rig at a 15 degree angle. It is form fitted to the rig, allows good clearance to all the controls front and rear, and raises it up off the table just a smidge.
Mike thanks/blames me for his purchase of the TR-45L and asked if I wanted one of his 3D-printed tilt cradles for my TR-45L. I just received it today at no cost to me–thanks, Mike!–and I really like the angle for using the TR-45L in my shack (and in the field, for sure).
You might recall a recent POTA activation where Jonathan (KM4CFT) joined me at the Vance Birthplace K-6856 US-6856–?
Jonathan used my Penntek TR-45L for his portion of the activation, and I was pleased he got to spend some time with this magnificent CW machine. You might also recall that it still had a buzz in the speaker audio–something inside the radio was vibrating.
KM4CFT working the TR-45L in late December 2023.
I tried to track down the buzz as Jonathan operated by tightening some of the screws holding on the speaker grill (yeah, I’m sure that was annoying, and he’ll think again before activating with me in the same space–!). I knew, though, it was something inside the chassis that was vibrating with audio.
As I also mentioned, my TR-45L was a prototype unit (I helped Beta test it)–it had a couple of mods and wasn’t exactly representative of the upgraded production model.
John (WA3RNC) at Penntek reached out to me after I published my recent field report and video; he offered to upgrade my TR-45L to the production chassis which would sort out the buzz. I was most grateful, of course!
He then asked if I would be interested in checking out the TR-45L “Skinny,” which is essentially a TR-45L in a much skinnier chassis. The Skinny model lacks the ATU and battery options but is lighter weight and more portable. I mentioned to John that I’d like to purchase one, actually. Since John was interested in sponsoring QRPer, we ended up working out a barter (at full market price) for ad space. I love this arrangement, actually, because I was going to approach him about sponsorship at some point anyway.
The Skinny!
Now keep in mind that the TR-45L is one of my favorite CW radios. I love the audio, the receiver characteristics, and the “Apollo era” aesthetic. I think it’s one of the best-looking and best-sounding radios on the market.
The Skinny is just like the bigger TR-45L, just roughly half the depth. I did have concerns that the audio wouldn’t be as good since the acoustic chamber would be smaller, but turns out, I had nothing to fear. The Skinny’s audio is on par with its bulkier sibling.
There was no learning curve with the Skinny because 1.) it’s identical in operation to my TR-45L and 2.) Penntek radios have super simple interfaces, and almost every function has a top-level direct control.
Zebulon Vance Birthplace (US-6856)
On Tuesday, February 27, 2024–the day after receiving the TR-45L Skinny–I packed it up and took it to the Vance Birthplace for its inaugural POTA activation!
That day, I had about 90 minutes to enjoy an activation, and I was looking forward to spending time with the new Skinny.
Vance was a great choice that day because the weather was moody; it was gusty, rainy, and I knew their picnic shelter would provide excellent cover.
The Skinny (in its padded bag), the MC-750 and my ABR cable assembly.
The TR-45L Skinny, unlike my original TR-45L, has no internal Z-Match ATU, nor does it have an internal battery. In fact, there’s no room for either in the Skinny, so it’s not even an option.
I paired the Skinny with my Chelegance MC-750, which is a resonant antenna when deployed correctly, so there was no need for a matching device. I supplied power via one of my 3Ah Bioenno LiFePO4 batteries.
Setup was simple and easy!

On Sunday, March 3, 2024, I had a couple of errands to run in downtown Asheville and also had to pick up my daughter.
I ended up having about 40 minutes to kill and, since I had my Elecraft KH1 field kit packed in my EDC bag, I thought it might be fun to fit in a little radio time.
Since I was downtown, the only viable POTA site to hit would be the Thomas Wolfe Memorial–you might recall my activation there last year–but technically, the park was closed. It is an urban park in the middle of Asheville, and there are no gates to keep people from walking across the grounds, but still, I’d feel better activating with permission from the staff first. (I’m pretty sure they’ll grant that permission, by the way.)
Instead of activating, I decided to do a little POTA hunting.
I parked at the spot where I planned to meet my daughter and grabbed my KH1 field kit.
My good friend, Ara (N6ARA), designed a small 3D-printed adapter that allows his TinyPaddle Plug to fit the KH1 securely. He sent me (free of charge) this new key/adapter to evaluate.
The adapter is a super simple design that works with the TinyPaddle Plug (not the TinyPaddle Jack).
I hadn’t used this new adapter in the field yet–I only very briefly tested it at the QTH a couple of days prior.
I mentioned last year, shortly after the KH1 was introduced, that I expected a number of 3rd party paddles to start appearing on the market. Since the interface with the KH1 is a standard 3.5mm plug, it does open the door to 3D-printed designs and experimentation. Admittedly, it’s a small space to fit in a paddle, but it’s doable.
I believe N6ARA was actually the first non-Elecraft paddle I used on my KH1 because his TinyPaddle Plug will fit it natively. That said, the new KH1 adapter makes it a proper secure fit–the way it should be!
Side Note: The OEM Elecraft KH1 paddles (the KHPD1s) are now in Revision 2, and all KH1 owners (who received the original paddles) will get version 2 paddles eventually via Elecraft for free.
The original KH1 paddles have a green circuit board.
I haven’t received my Rev 2 paddles yet, but I know I will before long. It’s my understanding that the Rev 2 paddles have a much better feel, and keying is more accurate.
Still…it’s brilliant that Elecraft used a standard jack so that we hams can design our own paddles if we like.
The TinyPaddle Plug
Ara’s TinyPaddle design is super simple, and while he originally designed the TinyPaddle to be a back-up option, I know a number of hams who use the TinyPaddle as their main field key.
Again, I can’t stress how cool it is to have a radio that allows you the flexibility to hit the air pretty much anywhere, anytime.
The KH1 is so quick to deploy, low-impact, and low-profile.
It’s as conspicuous as holding a transistor radio with a telescoping whip. So far (it’s still early days, let’s be honest here) no one has seen me with the KH1 and asked me if I’m a spy. I can’t count the number of times I’ve been asked this over the years of POTA activating!
Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format. To that end, welcome to another QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!
My good friend, Vince (VE6LK), came up with a great idea a few weeks ago: reach out to CW ops and ask one question that might help newcomers to Morse Code. Each video is 2-3 minutes long and features a number of ham radio operators who operate CW (I’m chuffed to be one of them). I’ve learned something from each of these videos.

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!
