Last month, my buddy Steve (VA3FLF/KM4FLF) was in North Carolina visiting family and we hoped to meet up in person at some point. Thing was, both of our schedules were pretty busy with various family activities and projects.
On Wednesday, September 21, 2022, we found an opening in the evening that coincided with a trip to do a little caregiving for my parents. We agreed to meet up at Lake Jame State Park (K-2739) which was on my way and also convenient to Steve.
Steve is also a fan of Parks On The Air, so why not fit in an activation? No better way to spend time with POTA family than at a POTA park, right? Right!
I arrived at the park around 18:30 local (22:30UTC) and set up MM0OPX’s 40 meter end-fed half-wave.
I only had one radio with me at the time: my prototype Penntek TR-45L.
At that point, the TR-45L had not yet been released and was in the very final stages of Beta testing. I was waiting on one more firmware update to bring the radio up to what would eventually be version 1.
Since I was still waiting on the final update that sorted out the CW message memory recording function (and boy did it–the final version is benchmark) I didn’t use message memories during this outing.
I offered Steve a hand at the TR-45L, but he claimed he wasn’t a heavy CW operator–he was interested in helping me with logging, though. How could I refuse that?
As I noted last week, I participated in the W4G SOTA campout at Lake Winfield-Scott Campground in the Chattahoochee-Oconee National Forest in north Georgia.
In short? It was amazing!
I thought I’d share a few photos and memories…
Campsite and friends
These SOTA campouts typically involve an announcement via the W4 SOTA group then we all make individual reservations at the chosen campground. Since we’re not reserving the whole campground as a block, we tend to share our individual camping sites with others who might not have been able to reserve a spot.
At Lake Windfield Scott campground, the SOTA group did reserve one large group campsite, but only a couple months ago it was canceled by the park service due to a trail maintenance group that needed it.
Typically, I camp with my friend Monty, but he had other family plans that weekend.
When I found out my buddy Joshua (KO4AWH)–the fellow behind Tufteln products–needed a spot to pitch his tent, I offered up my site.
As you can see in the photo above, both of our tents fit on the tent pad with absolutely no extra room to spare. 🙂
It was such a pleasure getting to know Joshua. What a kindred spirit and super nice fellow.
KO4AWH (left) and K4SWL (right) on the summit of Black Mountain.
We ended up doing all of our SOTA activations together as you will see in upcoming activation videos and field reports.
Joshua is as pack and organization obsessed as I am. A proper pack nerd! I really enjoyed checking out his bags, cases and all of the brilliant accessories that are a part of his field kits.
He brought both an IC-705 and TX-500 along for the ride. He logs in the field using the HAMRS app (same one I do) but on an iPad Mini (see photo above) and I must admit that the size of the iPad mini is nearly ideal–much better than a phone for logging.
He also used the SDR-Control app to connect wirelessly with his IC-705 and operate digital modes.
Summits
We activated a total of three summits during the weekend (Big Cedar,Black Mountain, and Yonah Mountain). It would have been easy to activate six or more if that was the goal–the area is chock full of accessible summits.
As many of you know, I’m a bit of a backpack geek (okay, that’s an understatement).
If you don’t believe me, listen to the Ham Radio Workbench episode where they invited me to take a deep dive into my world of packs, bags, and organization. It’s not for the faint of heart or the short of time. (It was seriously fun, though!)
You would think being a pack geek that I would produce more videos showing a breakdown of what’s in my packs and how I organize them. The irony is I watch numerous videos on YouTube of how others pack out their various field and travel kits.
I’ve had several requests to do a video about my main SOTA pack which is designed around the Spec-Ops Brand T.H.E. Pack EDC tactical backpack (see above). I think the reason why I haven’t made a video and post yet about this pack is because I knew it would be quite detailed and, frankly, take a lot of time to detail.
That said, here we go!
Designed to be modular
This particular pack is not set up to be a fully self-contained field backpack for just one radio. Quite the opposite: I use its main compartment to hold a wide variety of modular field kits I’ve put together.
What do I mean by “modular”–?
As I prepare my pack to hit the field, I decide which radio I plan to take; typically that radio is in a pouch, bag, or case of its own that contains radio-specific connectors and accessories.

Field Report and Lessons from Torrey Pines State Beach (K-3580)
by Rich (KQ9L)
As you can tell from my call sign, I am a W9er, but recently had the opportunity to travel to California and specifically to the San Diego area. I thought it would be fun to try to activate a park near my hotel. I consulted the POTA website and found one park which was within 5 miles of my hotel, perfect!
While planning for the trip, I carefully chose and packed my gear to minimize added weight and bulk of my carry-on luggage. Because on this requirement, I chose my Elecraft KX2 with built in battery, my KXPD3 paddles, a K6ARK end-fed half-wave and the telescoping fishing pole from the PackTenna portable mast system.
Everything fit perfectly into a Lowepro CS40 case and Tom Bihn HLT. I did not bring the tripod from the PackTenna system to cut down on weight and bulk.
The hardest part of traveling with this setup was the fishing pole as I could not fit it diagonally in my carry-on legal luggage and I ended up having it sticking out the top of my soft side Patagonia MLC carryon backpack / travel luggage.
I received a few odd looks from passengers and airline personal but to my relief I did not get hassled for the odd looking thing sticking out of my luggage. To minimize the space my luggage occupied in the overhead storage, I simply pulled the pole out of the luggage and stowed it in the bottom of the overhead bin. Easy! Everything made it safely to my destination and no the got destroyed.
This morning [October 15, 2022] I decided to go out early to activate Torrey Pines K-3580 which is just north of San Diego.
I ran into a problem which I guess I should’ve anticipated. Being from the central time zone and normally a 5 AM riser, I found myself ready to go by 3 AM Pacific time. I dillydallied for a few hours and watched a few of your YouTube videos to get me psyched up and ready for the activation.
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.
After returning from Canada this summer, I had a number of projects on the table including three radios to evaluate and a number of DIY projects on our investment house. The home projects took priority, so for the month of August, I did very little in terms of POTA activating.
In September, there was one radio in particular I was very eager to take to the field (besides the Penntek TR-45L). That was my Elecraft KX1, “Ruby.”
Before leaving for Canada, Ruby went into surgery once again under the care of my good friend “Dr.” Vlado (N3CZ).
I couldn’t figure out why she kept dropping power output to nil after being on the air for 20-25 minutes. I knew Vlado would sort out the issue.
Vlado discovered the source was a cold solder joint that was failing when the radio would become warm from operating. He fixed this and checked a number of other spots on the board.
He then tested the KX1 on a dummy load for and hour and she performed flawlessly after the surgery.
He fixed Ruby in early June and then we went to Canada for two months. I never put Ruby on the air in Canada.
After our return to the States, I was eager to take Ruby out to the field again and that’s exactly what I did on Sunday, September 11, 2022.
Lake James State Park (K-2739)
Lake James State Park–along with South Mountains State Park–are the easiest parks for me to hit during my nearly weekly travels on Interstate 40. I feel so fortunate that both are superb POTA sites with loads of spots to operate.
I arrived in the late afternoon and to my surprise there was hardly anyone at the park (I think it was a little too close to evening mealtime for families).
I set up my station at a table close to the parking area just to keep things simple. I was looking forward to enjoying at least 30 minutes on the air and seeing just how well Ruby might hold up.
I decided to use the Tufteln End-Fed Random Wire antenna knowing it would be a quick to deploy and frequency agile.
I tried to use the KX1 ATU to tune the random wire, but I wasn’t pleased with the SWR. Frankly, it was doable (1.9:1 on 20 meters), but I wanted something much closer to 1:1 since I was already only pushing 2.5-3 watts output.
Keep in mind, the KX1’s internal ATU is not in the same league as the ones in the Elecraft KX2, KX3, or T1–the KX1 ATU has a much smaller matching range.
Also, I suspect Ruby’s ATU wasn’t built for optimal performance by the original builder. I do plan to re-work her ATU as best I can at some point in the future.
I pulled out the Elecraft T1, put the KX1 ATU in bypass mode, and hooked it up to the antenna. The T1 had no problem at all finding 1:1 matches across 40, 30, and 20 meters, of course.
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.
This year, I’ve had a couple of readers very kindly offer to loan me their FX-4C transceivers to take to the field and review.
Those offers have been very temping because I’ve only heard positive comments from owners of this wee feature-packed SDR transceiver designed by Yu (BG2FX).
Earlier this year, I learned that Yu was retiring the FX-4C and would be introducing two new radios, so I decided to hold off on an FX-4C review for this reason.
My buddy, Don, informed me that the new radios were now available for pre-order, so I checked out the option on Yu’s website, and placed an order.
Details (features and specs) are still a little sparse because BG2FX is still finalizing the design and lining up production, but here’s a snapshot of the two models based on Yu’s preliminary info:
The FX-4CR can push 15-20 watts on most bands according to John, which is most impressive for a one pound radio that fits in the palm of your hand! It covers 80 – 6 meters, sports a color screen with a 48 kHz wide waterfall display, an internal sound card for digital modes, built-in speaker and microphone, 9 – 18 VDC input range, and even sports Bluetooth!
That’s an impressive array of features for $550 US (on pre-order).
The FX-4L
I pre-ordered the FX-4L and am told by Yu that it should ship by end of October or early November 2022. I wouldn’t be surprised if that’s an optimistic projection.
The FX-4L is essentially a more basic QRP version of the FX-4CR; it’s maximum output power is around 5 watts.
It’s very similar to the FX-4CR in many respects: it has the same display from what I can tell, covers 80 – 6 meters, has a wide voltage range 9 – 18 VDC, sports an internal sound card, and is super compact and lightweight.
The FX-4L doesn’t appear to have Bluetooth. Lu doesn’t mention a built-in speaker or microphone, but there’s an obvious speaker grill and even a small hole that might be a microphone. I’ll try to confirm this. Yu does note that there’s room in the chassis for the user to add a battery or ATU.
I’ve been more interested in the FX-4L because, as you likely know, it’s very rare for me top operate over 5 watts of power.
That said, I certainly see the appeal of a 15W+ radio like the FX-4CR.
(Many thanks to Yu for sharing all of the FX-4L photos above.)
Stay tuned!
I’m really looking forward to checking out the FX-4L and also reading AE5X’s assessment of the FX-4CR.
I’m curious if anyone else has pre-ordered one of these radios. Also, if you’re an FX-4C owner, I’d love to hear your comments!
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.
