The Mountaintopper MTR-3B is a popular QRP portable HF transceiver that has a bit of “cult-ish” mystique about it. The radio seems to hit the sweet spot of size, weight, performance and capability desired by so many portable operators.
While I have operated the MTR-4B, and quite like it, I have yet to get my hands on the much vaunted 3B. Hopefully that’s about to change as LNR Precision has released details and pricing for the next iteration of this legendary radio.

You can check the specs for yourself on the LNR Precision web site. What piques my interest is that the band plan adds 15 meters at the expense of 30 meter coverage and the integrated touch keyer eliminates the need to pack a set of paddles.
Things that I am wondering out loud:
Does plugging in paddles disable the touch sensors?
Can the frequency display be configured to show MHz?
What is the receive current draw?
How many “R”s in “Curahee”?
Perhaps the announced pre-release of the user manual will answer these questions.
What do you all think of what we’ve seen of this new Mountaintopper so far?
I’ve had a production unit of the Xiegu X6200 since June of this year and have made several field reports using it for both SSB and CW.
You may have noticed, though, that I haven’t used it much in the field since June.
The reason? I’m primarily a CW operator, and the original firmware had some frustrating CW keyer timing issues.
These keying issues are most noticeable when operating in iambic mode, especially when trying to form letters like C, R, or K by squeezing the paddles. Often, when I try to send a “C,” as in “CQ,” the keyer produces a “B” instead. If you’ve watched any of my previous X6200 videos, you might have seen this happen a few times.
After some time using the radio, I can adapt and reduce the miskeying, but it still happens occasionally. I suspect part of the issue is related to the keyer timing in relation to the transmit/receive switching.
While these keyer issues aren’t severe enough to prevent me from completing an activation, they are certainly annoying.
As I’m reviewing the X6200 (thanks to Radioddity for the extended loan!), I reported the issue to Xiegu back in May and hoped the first firmware update would address it.
The first firmware update, Version 1.0.1, was released in early August. There was an earlier release, but it was retracted due to other issues.
I checked the release notes and didn’t see anything specific about CW keyer timing in the long list of fixes. I had hoped another update would follow soon, but none has been issued yet. Meanwhile, several readers and subscribers have asked me if the keyer issue was resolved.
I decided to update the firmware and take the X6200 out for another field test.
Still, I had a great time squeezing in a quick activation with the X6200, and I thought I’d share the video and a mini field report with you now!
Pisgah National Forest (US-4510)
My wife and I were out while one of our daughters was in Shakespeare rehearsals in Mills River, NC on Friday September 6, 2024. We had a number of errands to run, but my wife kindly worked with me to carve out 30 minutes for a quick activation.
The most convenient POTA location was the Sycamore Flats Picnic Area in Pisgah National Forest.
By mid-afternoon, the park was busy, but most of the picnic areas were open, giving me plenty of options for setting up.
With limited time, I turned on the camera to start my real-time, real-life activation video and got straight to work.
Since the X6200 has a built-in ATU, I decided to use my PackTenna End-Fed Random Wire, as it’s quick to deploy with its 31’ long radiator—any nearby tree would do.
Next, I paired the X6200 with my BaMaKeY TP-III, plugged in the antenna, and found a spot on the band to start operating!
Time to POTA!

After tuning up on the 20-meter band, I spotted myself and started calling CQ POTA. Fortunately, hunters quickly responded.
In just twelve minutes, I logged thirteen contacts. Thanks to all the hunters!
My activation was brief, and I was so focused on making contacts and packing up that I forgot to take any photos of the radio in action. I’ve included some screen captures from the video instead.
I did manage to take photos of the logs:
QSO Map
Here’s what this five-watt activation 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.
As I discovered during this activation, the CW keyer timing issue has not yet been addressed in the firmware update.
After returning home, I made some notes and reached out to Xiegu to confirm that the CW keyer timing is still on their radar. They assured me that it will be addressed in the next firmware update. I’ll definitely test it and let you know once it’s resolved, so stay tuned!
If you’ve already purchased an X6200, I’d love to hear your thoughts about this all-in-one radio in the comments!
Thank you
Thank you for joining me during this short activation!
I hope you enjoyed the field report and my activation video as much as I enjoyed creating them!
Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon, and the Coffee Fund. While not a requirement, as my content will always be free, I really appreciate the support.
As I mentioned before, the Patreon platform connected to Vimeo makes it possible for me to share videos that are not only 100% ad-free but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files.
Thanks for spending part of your day with me! Have a brilliant weekend!
Labor Day weekend turned out to be full of labor here at QTH K4SWL. My wife and I had numerous projects to tackle, and my daughters had various activities scheduled as well. By Sunday, my wife looked at me and said, “You need a break. Why not spend tomorrow catching up on POTA?”
That was music to my ears.
I messaged my buddy, Vlado, to see if he might be interested in joining me, and he quickly replied, “Of course!”
So on Monday, September 2, 2024, Vlado packed his radio gear in my car, and we discussed where we should go. We had most of the day for radio, but we needed to decide if we’d head north, south, east, or west. In the end, we chose to travel east, as it offered the most options, including one site Vlado had never activated.
We decided to start at Lake James State Park. Since Vlado had only activated Lake James for the first time the previous day at the Paddy’s Creek Access, we opted for the Catawba River Access.
Lake James State Park (US-2739)
It was Labor Day, so we knew Lake James would get busy around lunchtime, which is why we hit it early. I also knew Paddy’s Creek Access would be much busier today because it has the beach, and I remembered how full the parking lot was during my Labor Day activation in 2023!
At 9:00 AM, when Vlado and I arrived at the Catawba River access, we were among the few people there, so we had our pick of spots to set up the POTA station.
For convenience—especially since there had been a deluge of rain the night before—we chose a spot close to the car, where I’ve activated a number of times in the past.
I also took this opportunity to show Vlado how to use an arborist throw line.
While I didn’t record the antenna deployment—frankly, I didn’t think about it at the time—I wish I had. Vlado was a natural!
On his second-ever throw, he snagged the perfect branch to deploy a 40-meter end-fed half-wave antenna.
CFT1 Time!
The CFT1 with Tufteln cover/stand, audio cable and pack with battery.
I knew exactly which radio I wanted to operate during this activation: the CFT1 by Jonathan (KM4CFT).
I had only recently swapped out my Beta unit for a production CFT1. As a thank-you to Beta testers, Jonathan let us keep the units we tested. I worked with Jonathan and Dan to return the Beta unit and compensate them for the difference.
In truth, there were only a few changes, mostly cosmetic, between the Beta and production units. The biggest improvement for me was that the Beta unit lacked a way to adjust the sidetone level independently from the AF gain. The production unit has this feature, which was my primary motivation for upgrading.
In addition, I prefer using radios that match what my readers and subscribers have. When I use a Beta unit, even if the changes are purely cosmetic, it generates more questions.
Interestingly, this wouldn’t be Vlado’s first time using the CFT1. He must have been one of the first people outside the Beta testing team to try it because we used it on Field Day alongside the TR-45L and X6200 (although you won’t see it in my report since it was still somewhat of a secret project at the time).
We paired my MW0SAW 40-meter EFHW and Bamakey TP-III with the CFT1. I also used my Anker Soundcore Mini speaker for audio.

Yesterday morning, around 12:00, I picked up a DHL parcel containing the Venus SW-6B. I was so eager to test it in the field that I dropped my lunch plans, took the SW-6B home, opened the box, and quickly attached Anderson Powerpole connectors to the supplied power cable.
I didn’t have time to do anything else, not even turning on the radio.
After doing some back-of-the-envelope calculations, I realized that if I skipped catching up on my email backlog (sorry!), and instead jumped in the car, I could fit in a one-hour activation on the way to visit my dad in Hickory, NC, that afternoon.
Not wanting to compete for the one picnic table at the South Mountains State Park Clear Creek access (the fastest detour), I decided to head instead to the Lake James State Park Catawba River Access en route. There are plenty of site options at Lake James, and mid-afternoon on a Tuesday, I knew it wouldn’t be crowded.
Lake James State Park (US-2739)
The weather was absolutely beautiful, and I was right: there were very few people at Lake James.
I left the QTH in such a hurry that I didn’t have time to gather all the components for the SW-6B field setup. Instead, I grabbed my SOTA backpack (which should, in theory, have an antenna, cable assembly, throw line/weight, key, and other necessary adapters and accessories).
I found a picnic table with plenty of antenna deployment options (i.e., trees!).
Luck was on my side, too: my first throw of the throw line made a perfect arc into a tree, giving my 40-meter end-fed half-wave an ideal configuration.
While deploying the antenna, a groundskeeper nearby started mowing a patch of grass with possibly the noisiest mower I’ve ever heard. 🙂 It was so loud I actually had to wait for him to move on because I found myself shouting at the camera mic. Ha ha!
As I mention in the video, this is just the kind of QRM you should expect at a good park. The grounds at NC parks are truly outstanding, which takes a lot of work, and I’m very appreciative. It was just a minor inconvenience.
SW-6B Setup
After deploying the antenna, I set up the SW-6B and spent some time in the video (below) explaining the front panel controls.
I noted in the video that I purchased one of the very first production models listed on the Venus website.
There are a few options available: a metal case, a plastic case, and with or without an internal battery pack.
At the time, Dale (BA4TB) only had the metal case version built, so that’s what I ordered, with an internal battery. It’s the priciest option. The total cost, including DHL shipping to the US, was $344.30.
The metal case is very basic. One downside is that it doesn’t have a positive latch—there’s no easy way to secure the lid. For example, if you turn it upside down, it will open. The plastic version has latches—knowing this, I would have much preferred the plastic case.
That said, the metal case has a lot of charm. I plan to secure it with an elastic band or see if I can adapt mine to a plastic case later.
The internal battery didn’t come fully charged, of course, but it showed 11.3V, which is well within the SW-6B’s voltage range. Knowing this would be a short activation, I opted to use the internal battery instead of grabbing my (comically large, compared to the SW-6B) 15Ah battery from the car.
After turning on the radio, I was pleased to find that the internal speaker provided plenty of amplification for field operations.
It was time to get the SW-6B on the air!

The new FTX-1F is a portable transceiver utilizing SDR technology and provides 6W of power output with the 5670mAh Lithium-ion battery pack (Which enables 9-hours stand-alone operating time on the HF bands, SSB mode, and 8-hours operating time on the V/UHF bands, FM mode based on a 6-6-48 duty cycle). Up to 10W of power output is available when using an external DC power supply.
FTX-1F – True All-Rounder
HF/50/144/430MHz All Mode Field Transceiver
Providing stand-alone 9-hours of operation
This information and the sample shown at HAM FAIR 2024 are only the preliminary introduction.
Detailed information will be announced at a later date.
A number of the fundamental and remarkable features of the new FTX-1F are:
Operation in SSB, CW, AM, FM and C4FM digital modes
SDR Technology and 3DSS (3-Dimensional Spectrum Stream) on a 4.3-inch high-resolution full-color touch display
panel
Two independent receiver circuits provide true simultaneous dual-band operation, whether in the same band or in
different bands. For example: SSB communication on HF bands simultaneously with C4FM digital communication
on V/UHF bands (*HF+V, HF+U, V+V, U+U, V+U, U+V)
Two Loud speakers ensure clear and powerful audio output
An optional Automatic Antenna Tuner can be attached to the rear of the transceiver with the 5670mAh high-capacity
Li-ion battery pack. The optional Cooling-fan, which is necessary for comfortable FT8 operation, can also be
combined with the antenna tuner. (All-in-one rear panel design)
PMG (Primary Memory Group) function can register and monitor up to 5 frequently used frequencies
MAG (Memory Auto Grouping) function enables Memory Channels to be categorized in each band that can be
quickly recalled by band groups (HF/VHF/UHF/AIR/OTHERS)
USB ports support CAT operation, audio input/output and TX control
The new FTX-1F will be available early 2025. Please be ready for this forthcoming exciting new radio!
When I asked, in the past, what readers would like to see in an FT-818 replacement, many wanted a spectrum display and SDR technology–it seems like Yaesu was listening.
There’s no built-in ATU, but it appears they will have an “[a]n optional Automatic Antenna Tuner can be attached to the rear of the transceiver with the 5670mAh high-capacity
Li-ion battery pack.”
What’s most surprising is that the FTX-1F has two independent receiver circuits. This is quite an innovation in the world of field-portable HF radios.
I will post more details when they become available. Very curious about the output power, size/weight, and and receiver specs. It would be brilliant if they managed to get FTDX10 receiver performance in this portable form-factor.
My buddy Jonathan (KM4CFT) made a big announcement this morning.
He’s been working tirelessly since the start of the year, designing and testing a brand-new field-portable CW transceiver he’s dubbed the CFT1.
As of this morning, you can purchase the transceiver kit on HamGadgets.com.
A little backstory
Jonathan first mentioned his plans to design a CW transceiver back when we were doing a joint POTA activation at the end of December 2023. At the time, it was just an idea. When he said he planned to have it ready for sale in 2024, I was skeptical. I mean, he had a day job and had never designed a radio before. How could he pull that off in such a short timeframe?
Fast forward to Four Days in May/Hamvention in May 2024, and wouldn’t you know it, Jonathan had a working prototype on display! I was blown away. Within a couple of weeks, he was contacting us beta testers, eager to get revision one units into our hands.
I got my CFT1 in June and immediately put it through its paces in the shack. Even in beta, this little radio was rock solid – I was seriously impressed!
I thoroughly tested the CFT1 in the shack, both on a dummy load and with my QTH antenna. If you’re into SOTA or POTA and I worked you in June, chances are it was with the CFT1.
Vlado (N3CZ) making field day contacts.
I even took the CFT1 out for a spin on Field Day. Vlado (N3CZ) and I were both impressed with how well it performed in that crazy RF environment. Remember, this isn’t a contest radio, but it didn’t seem to overload at all. Impressive!
When I heard Jonathan was launching the CFT1 today, I figured I’d do a quick POTA activation to showcase this awesome little radio.
The Blue Ridge Parkway (US-3378)
Yesterday morning, I was heading to Mission Hospital in Asheville to visit a family member who had just been admitted. I realized I had enough time for a quick activation at the Folk Art Center on the way.
I arrived at the parking lot around 8:30 AM. It was pretty empty except for the grounds crew. I set up at my usual picnic table.
I paired the CFT1 with my KM4CFT End-Fed Half-Wave, trimmed for 30M with a 40M linked extension. I was hoping for some 40-meter action early in the morning. Setup was a breeze. My throw line cooperated beautifully – the 40M EFHW was practically vertical!
Naturally, I filmed the whole process: setup, activation, and pack-up. Before I started the activation, I spent a few minutes talking about the CFT1 – its design philosophy and what I like about it. Hopefully, this will help you decide if it’s the right radio for you.

My buddy, Jonathan (KM4CFT), is close to releasing a new CW Field Transceiver kit he designed for POTA, SOTA, and pretty much any other field radio activity.
Today, he shared the following photo, which is a bit of a teaser:
Those of you who attended Four Days in May this year may have already gotten a proper sneak peek and even operated a prototype of this radio.
Jonathan tells me that he’ll be releasing details in the near future and you’ll soon be able to order the kits via Radio Dan’s eBay store[eBay partnership link] or via his website.
Of course, I’ll also post details here on QRPer.com when the new radio kit is live and ready to order! Stay tuned!
In short? It was amazing and certainly a fabulous way to start the day.
We were in Wilmington because one of my daughters was attending a week-long program at NC State University, and the other was attending a similar program at UNC Wilmington.
That Tuesday afternoon, after dropping my daughter off on the campus of UNC Wilmington, my wife suggested we hit Carolina Beach State Park for a POTA activation. It didn’t take me a microsecond to agree to that plan!
Carolina Beach State Park (US-2722)
Carolina Beach State Park, located just south of Wilmington, is a unique spot full of natural wonders. The park covers over 760 acres of Pleasure Island, with diverse habitats ranging from the impressive 50-foot Sugarloaf Dune (which used to be used as a navigational aid) to the fascinating limesink ponds, each with its own special plant community.
The park is also home to the Venus flytrap, a rare carnivorous plant found only in a small part of the Carolinas. You can explore the park’s trails, winding through maritime forests and maybe even catching a glimpse of these fascinating plants in action. The park also has a marina for easy access to the Cape Fear River and the Intracoastal Waterway, making it a great spot for boating and fishing.
We arrived at the park a little before 4:00 PM local time. Had it not been so hot and humid, we would have hit one of the park’s trails before finding a spot to do POTA, but the weather being what it was, both of us were happy to spend time in the shade.
We pulled into the main picnic area and quickly found a spot to set up. As I pulled out my radio and camera gear, my wife, Heather, pulled out her travel watercolor kit, all packed in a Tom Bihn HLT1 (we’re a pack geek family!).
When Heather joins me on POTA activations, she almost always sets up somewhere and paints while I activate. I love the fact that we both enjoy the experience in different ways.
In fact, my buddy Steve (KC5F), who is also an avid POTA activator, performs almost all of his activations with his wife, who also paints while he activates. He told me that she likes a good couple of hours of painting, so he typically racks up a lot of contacts in that amount of time.
Setting Up
The first thing I did was set up my Thermacell mosquito repeller–it needs a few minutes to do its thing and clear out the mozzies. The model I carry, the “backpacker,” fits a standard backpacking stove canister. I’ve recommended this one to many other POTA ops who operate in areas with mosquitoes–so far, it’s never let me down!
After watching an activation earlier this year at Tuttle Educational State Forest, where I placed my KX2 and logbook on a wet and dirty picnic table–covered in pollen and other tree bits–Alanna ordered a blue Gingham picnic tablecloth and whisk and had it sent to me.
I’ve had this tablecloth packed in the go-box I keep in the Subaru, and this activation was the perfect time to put it to use because the table I chose needed cleaning!
Thanks, Bob and Alanna!
Next, I deployed my PackTenna 9:1 End-Fed Random Wire antenna and paired it with my Elecraft KX2.
New paddle mount!
I did (finally) get to try out a new piece of kit in the field: a newly-designed paddle mount from Steve (KB3SII) at QRPworks.
Steve handed this prototype mount to me at Hamvention this year. It’s an updated design of one we tested last year.
You basically attach the mount to the front of the KX2 (or KX3) and place a paddle like the Bamakey TP-III that has strong rare earth magnets. The paddle locks onto the metal pad and makes for a rock-solid, ergonomic keying experience.
Steve also sent me two short 3.5mm angled cords to connect the key to the radio, but I forgot to pack them for the trip. My standard paddle cable worked fine, although I had to angle the TP-III slightly.
Note that Steve plans to have these paddle mounts in production and available on the QRPworks website in the coming weeks. When they’re available, I’ll post a direct link.
With the KX2 set up and ready to go, it was time to hit the air!

I started calling CQ POTA on 17M and discovered that it was a fairly quiet band. Nonetheless, I worked two stations in about six minutes. Secretly, I was hoping there might be a 17M path into Europe, but then again, it was a bit late in the day for that (and it seemed 17M wasn’t terribly energized).

Yesterday, I met up with Jonathan (KM4CFT) who happens to be in town visiting family over the holiday weekend. Before our POTA activation, he mentioned that he is now selling a 3D-printed paddle kit for $34.95 on eBay:
When our family needs a change of scenery without a long drive, Mount Mitchell State Park is our go-to destination. I’ve mentioned before that it’s my “happy place” here in North Carolina. Mount Mitchell is only about 6 miles from our home as the crow flies, but it takes about 50 minutes to drive there, and it’s not in the direction of any of our usual destinations. Heading up the Blue Ridge Parkway and watching the flora change with elevation makes it feel like a proper getaway.
On Sunday, June 16, 2024, we wanted just such a getaway, as my wife and daughters were treating me to some Father’s Day fun. After visiting my father-in-law in the hospital in the early afternoon, we drove to Mount Mitchell.
Mount Mitchell State Park (US-2747)
Sundays on Mount Mitchell tend to be busy, especially in the summer. However, on this particular Sunday, it was rainy, foggy, and there were storms in and around the area.
Weather like this never bothers us on Mount Mitchell, as it can shift in an instant, as long as thunderstorms don’t intrude.
As soon as we arrived, I grabbed my radio bag from the car and found an empty picnic shelter. I’d been hoping for a free shelter since it was raining, and fortunately, we got our pick!
One of the first things I did after dropping off my pack was to tie Hazel to a picnic table because she was laser-focused on a chipmunk she saw run up a tree next to the shelter. That dog drives chipmunks and squirrels crazy, I’m sure.
My wife and daughters dropped off some art supplies at one of the shelter tables, then went on a short hike while I performed my POTA activation.
Note that Mount Mitchell is also a SOTA summit, but the picnic area is not within the activation zone. I could have easily gone to one of my go-to SOTA spots on the summit and knocked out a SOTA activation quickly (only four contacts are needed), but I wanted to save that for another day. Plus, being in the shelter meant that I could have a nice leisurely, dry activation!
I brought along my Penntek TR-45L and planned to pair it with a random wire antenna for the activation. However, since the weather was iffy—again, my primary concern was any thunderstorms that might sneak up on us—I decided to skip the wire antenna and go tabletop instead.
Fortunately, my Elecraft KH1 lives in my EDC bag at all times, so I set it up for tabletop mode.
You might recall that I have used the Elecraft KH1 adapter in previous activations and I think it works brilliantly. The first version of Elecraft’s adapter had one issue: the parts would fall apart if you weren’t careful with how you attached it to the KH1.
Joshua designed his right-angle adapter with captive components so that it’s all in one piece and can’t come apart.
I should note here that Elecraft actually updated their right-angle adapter design so that it also has captive components as well—so you have two choices! I’ll use the new Elecraft adapter in a future video and field report.
Joshua’s Tufteln design works really well (it’s also less expensive than the OEM adapter), and I like that it’s bright red, which means I’m less likely to leave it in the field!
