A tour and deep-dive of my SOTA/POTA Backpack (Spec-Ops Brand T.H.E. Pack EDC)
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.
In truth, I have done this before, of course–once showing how I pack out my GoRuck GR1 for field radio and travel and another time showing how I pack out my TX-500 field kit in a Red Oxx Micro Manager. I plan to do more.
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.
I put the radio in the main compartment, then I add a battery kit, logging kit, an antenna kit, arborist throw line, and an accessories kit that contains a key, cables, adapters, etc. Continue reading A tour and deep-dive of my SOTA/POTA Backpack (Spec-Ops Brand T.H.E. Pack EDC)
Scott builds a base for his ZN-Lite II paddles
Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:
ZN-Lite II Update
by Scott (KK4Z)
I’ve had these paddles for about a year now but I haven’t used them much. Here is a link to my original review: https://kk4z.com/2021/11/24/n3zn-zn-lite-ii/. The reason is rather complex. they are small but because of their design, they can’t be held in the hand like some other paddles. If you put them on a table with the included Lexan base, they are so light, you have to use both hands to operate them. To me, it was a conundrum. These are very well-built, precision paddles and as smooth as any well-made paddle out there. My original thought was to use them for POTA. I was a little discouraged with their functionality, and even offered to sell them at one point — but I didn’t.
Here lately, I have been pairing my paddles with my various radios. My Begali Signature with my IC-7610, Begali Traveler Light with my IC-7300, Begali Adventure with my IC-705, and my N0SA SOTA paddle with my TX-500. I have a Penntek TR-45L on order. It is a CW-only radio that has a nice retro look. I thought these paddles would be a great match for this radio. What I want for this radio is a set of paddles that can be operated with one hand. The TR-45L is a tabletop radio https://www.wa3rnc.com/store/penntek-tr-45l-qrp-transceiver. I envision its use at a park during a POTA activation. I decided what my ZN-Lite II paddles needed was a heavier base. I ordered from Amazon a 3″ diameter, 1/2″ thick piece of steel.
I drilled a hole to mount the paddle and 4 smaller holes to mount the rubber feet. The paddle hole is countersunk on the bottom so the screw head is below (or above) the surface of the base. That way it can be used without the feet.
The holes for the feet were drilled and tapped for 8-32 thread. I had to drill the hole all the way through because I didn’t have a bottom tap. Without a bottom tap, there would not have been enough threads in the hole if I didn’t drill all the way through. When I do these projects, I basically use hand tools and in this case, I used a cheap drill press I bought from Home Depot.

Rich packs the KX2 field kit for air travel and a POTA activation!
Many thanks to Rich (KQ9L) for sharing the following field report:
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.
I got out to the site right at sunrise and set up without much difficulty. I found the vegetation to be conducive to setting up the fishing pole by leaning it up against some of the shrubbery. Continue reading Rich packs the KX2 field kit for air travel and a POTA activation!
3 Watts of Fun: Pairing the Elecraft KX1 and PackTenna 20M EFHW at South Mountains State Park!
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.
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.
I deployed the PackTenna within three minutes. Very easy and straight-forward setup.

Gone SOTA camping…
By the time this post has been published [I scheduled this one in advance], I’ll be offline and preparing for a long weekend of radio fun at the W4G SOTA Campout in north Georgia.
I’m looking forward to catching up with friends, trading (mostly true) stories, and hopefully activating a number of new-to-me SOTA summits and POTA parks.
As long as my ankle cooperates, I plan to hit at least a couple of summits each day.
If you care to chase me on the air, check out the SOTA Spots page and/or the POTA Spots page.
My activations will likely be super short so that I can fit in multiples within a day. That said, our campground is in Chattahoochee-Oconee National Forest (K-4473), so I should have longer evening sessions on the air.
At SOTA events like this, you can get away with only carrying an HT: it’s easy to work other activators Summit-to-Summit (S2S) on VHF since there are so many other SOTA ops on nearby summits.
I will still do HF, though, unless I’m really pressed for time. I’ve packed a wide variety of radios and antennas. In fact (typical me) I’ve packed more than I know I could possibly put on the air in one weekend.
I don’t expect to have mobile phone or internet service other than when I’m en route to or on summits. Obviously, I won’t be checking email during this time.
Frankly, there’s nothing better than a little offline & on-the-air time!
Have a wonderful weekend everyone!
Field Report: Giving the Elecraft KX1 a thorough post-operation POTA test!
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.

Ken’s photos comparing five field radios
Many thanks to Ken (WW5A) who writes:
Hello Thomas-
I enjoy reading the posts on the QRPer. The size comparison photos recently posted got me thinking. I had taken a photo several months back of a X5105, 817, RS918 (McHF), G90 and a 705, basically to do the same thing (size comparison).
I have attached them for your amusement [click to enlarge]:
73,
Ken WW5A
Thanks for sharing these, Ken. To me, it’s interesting to see the comparison between the FT-817 and the G90. When I owned a G90 I didn’t have an 817 at the time for comparison. It reminds me just how long/deep that G90 was! Also interesting to see that the mcHF clone is a wee bit wider than the IC-705. Thanks for sharing!
Photos: Comparing sizes of the Mountain Topper MTR-4B, MTR-3B, and Elecraft KX1
After sharing a few photos by request comparing the size of the Mountain Topper MTR-3B, MTR-4B, and Elecraft KX2 yesterday, I took a few pmore photos by request comparing those same radios with the Elecraft KX1.
I decided to simply post these on QRPer.com in case they could also be of help to someone else:
Mountain Topper MTR-3B v Elecraft KX1
Mountain Topper MTR-4B v Elecraft KX1
Elecraft KX1 v KX2
Photos: Comparing sizes of the Mountain Topper MTR-4B, MTR-3B, and Elecraft KX2
A reader/subscriber just asked for photos comparing the size of the Mountain Topper MTR-3B and MTR-4B. I know they were also curious how the MTR-4B might compare in size with the Elecraft KX2. Of course, one can look up the actual sizes, but sometimes a photo adds more context.
I decided to simply post these on QRPer.com in case they could also be of help to someone else:
