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 QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!
Check out this short article by John (AE5X) where he uses a CW Flea transmitter and Belka-DX receiver for a QRPp POTA activation. I love what John’s done here and I think I may have to give the CW Flea a go too someday.
In my last published field report, you might recall that I successfully activated a park using 500 milliwatts or ½ of a watt. I was so surprised by the results of using this QRPp power level I immediately made plans to push the power level even lower during my next activation.
Let’s face it, I was drunk with a lack of power!
QRPp
After my last field report, there were quite a few questions about the term QRPp and what it means. To be honest, I’m not sure if there’s an “official” definition, but here’s what is widely accepted as QRP power categories:
QRP: 5 watts to 1 watt (for some contest 10 watts = SSB QRP)
QRPp: Less than 1 watt to 100 mw
QRPpp: Less than 100mw
I don’t own a field radio that allows me to lower the output power to QRPpp levels. In fact, few of my radios actually allow me to lower power below one watt.
My Elecraft radios, however, do allow me to lower power output to as low as 0.1 watts or 100 milliwatts.
The plan
On Wednesday, December 7, 2022, my travel schedule shifted and it opened up the entire afternoon to play radio.
A rarity indeed!
It was very rainy and foggy that day and I didn’t have my ENO rain fly with me, so I decided to visit a park with a good picnic shelter to keep me, an my gear, nice and dry.
Fort Dobbs State Historic Site (K-6839)
I had four park options with covered picnic shelters within a 45 minute drive. I decided that I would try to activate Fort Dobbs State Historic (since it had been a couple months since I’d visited) and Lake Norman State Park would be my back-up plan.
Fort Dobbs is a small park, so I called in advanced and asked for permission to do the activation and also asked if their picnic shelter was reserved.
The rangers there know me, so the phone call was pretty quick–no need to explain POTA nor my motivations. They told me that on rainy/foggy December days they have so few guests that I was welcome to use the picnic shelter or even the entire park if I wished (perhaps an ideal time to erect a Rhombic antenna–okay, just kidding!).
The Dobbs park rangers an volunteers are the best!
Setting up
On the way to the site, I decided that I would deploy my MM0OPX end-fed half-wave I’d cut for 40 meters.
I’d like to start this field report with a side story. I’ll keep this reader anonymous since I haven’t asked for permission to post his story (although I’m certain he wouldn’t mind!):
A QRP Christmas Gift
Yesterday, I was contacted by a reader who had just received an amazing gift.
On Christmas morning, his wife presented him with a tiny wrapped box and inside there was a small note:
“Get yourself a great field radio. You have Carte Blanche!”
What an amazing gift…right–?! She literally said Carte Blanche!
Evidently, she is familiar with my YouTube channel (poor thing) because he often watches my activation videos on their living room TV. [Between us, I’m a bit surprised she still loves him after subjecting her to my videos.]
She told him, “Run your choice by Thomas before ordering.”
The funny bit? He approached me with this very question in November as he plotted a 2023 radio purchase. He couldn’t decide between the Icom IC-705 and the Elecraft KX2.
He wrote yesterday to tell me that he placed an order for a new Elecraft KX2 with all the trimmings; Elecraft’s KX2 “Shack-In-A-Box” package plus a set of KXPD2 paddles.
The KX2 is back-ordered due to parts availability, so he won’t receive his unit for several months, most likely.
Based on his operating style, I think he chose wisely. The IC-705 is a benchmark field radio, but he was looking for something that he could pair with a random wire antenna (the ‘705 lacks an internal ATU) and that would be easy to use on SOTA activations. He’s new to CW as well and loved the fact that the KXPD2 paddles attach to the front of the KX2.
Why do I mention this story? Because it’s not only fresh on my mind, but it’s the same radio and antenna I used during an activation on Thursday, December 1, 2022.
Tuttle Educational State Forest (K-4861)
As I pulled into Tuttle’s parking area that day I had a tried-and-true field radio kit pairing in my pack: my Elecraft KX2 and PackTenna 9:1 Random Wire antenna.
As I mention at the start of my activation video (see below), with the Elecraft KX2 and a random wire, I could easily activate all of the summits, parks, and islands I desire. It’s such an effective, flexible, and portable combo.
QRPp
To shake things up, I decided to knock the output power of the KX2 down to one half of one watt–500 milliwatts–at least for the CW portion of my activation.
As I mentioned in previous field reports, the W4G SOTA Campout was amazing fun this year. I enjoyed hanging with Joshua (KO4AWH) as we activated a total of three summits and a few parks–plus it was great meeting so many fellow SOTA activators at the Saturday evening potluck!
On Sunday morning, October 16, 2022, it was time to pack up the campsite and hit the road.
Although I was a little pressed for time, I decided to fit in one more activation as Joshua packed up his tent and before we took down the 40 meter Tufteln end-fed half-wave.
Chattahoochee-Oconee National Forest (K-4473)
Fortunately, our campsite was within Chattahoochee-Oconee National Forest and since all I needed to do was to connect my rig to our campsite antenna, setup took all of two minutes.
I pulled out the Mountain MTR-3B for this activation. It had been quite some time since I used this wee radio because I had only recently finished a review of the MTR-4B V2 (look for that review on QRPer.com very soon).
The MTR-3B is now permanently at-the-ready inside my MTR-3B ultra portable field kit, but since there was already an antenna and key in place, I only needed the radio, power cord, logging items, and battery.
I mentioned in a previous post that I’m quite behind publishing activation videos. Much of this has to do with the fact that I’ve been a pretty busy activator (by my standards) the past couple of months.
While I don’t make field reports and videos for each of my activations, I usually do one or two per week. Two is typically the max I can post because my field reports take 3-4 hours each to write-up and publish; it can be difficult carving that kind of time out of my busy schedule!
In order to catch-up, I’ve decided to post shorter format field reports from time-to-time; especially for reports like this one where I give quite a lot of info and detail in my activation video.
Immediately after wrapping up our SOTA activations on Black Mountain, we decided to hit a park on the way back to the campground. Desoto Falls National Recreation Area made for a short detour and a nice way to relax after a few miles of hiking that day.
We pulled into the parking area of Desoto Falls and set up our stations in the picnic area placing some distance from one another to help with any interference.
I pulled out my trusty Penntek TR-45L and two 28’/8.5m lengths of 24 gauge wire. I extended the radiator vertically and unrolled the counterpoise on the ground. The wires were connected to the binding posts on the back of the TR-45L (red=radiator, black=counterpoise). I used the built-in manual Z-Match tuner to match the impedance in short order.
It was so great to spend an extended weekend camping, hiking, and hopping on the air with other SOTA activators.
I especially enjoyed getting to know Joshua (KO4AWH)–the fellow behind Tufteln products— over that weekend. He needed a campsite and since my buddy Monty had to pull out of the trip due family activities, I was happy to share the tent site with him. It actually worked out quite well since we could then pair up and car pool to our SOTA and POTA activations.
What follows is a field report for two SOTA activations Joshua and I did back-to-back on Friday, October 14, 2022.
The trail head for both of these summits was only a few miles from our campsite at Lake Winfield Scott.
Gear:
Note that I used the same gear during both SOTA activations all packed in my Spec-Ops Brand SOTA backpack.
Black Mountain and Big Cedar essentially share the same trailhead at the Woody Gap Recreational Area parking lot on Highway 60.
We were on site early enough to grab a parking space. Keep in mind that it was Friday during leaf season, so there were quite a few hikers on the trails that day! In fact, by midday, the parking lot was overflowing with cars.
Almost by flip of coin, we decided to hit Big Cedar Mountain first. Turns out, Joshua had actually hiked to this summit in the past and even met a SOTA activator en route (and I believe this might have been his inspiration to try Summits On The Air!).
On Friday, October 7, 2022, I had a couple of errands to run in/around Morganton, NC. Of course, I always have POTA in mind so squeezed in an activation at nearby Tuttle Educational State Forest that morning. That activation took longer than expected due to swapping out antennas and radios, but it was a success and quite fun.
After Tuttle, I knew I could fit in one more activation if I made it quick, so I set my sights on Table Rock Fish Hatchery (K-8012), but first I had a couple of errands to run in Morganton!
I visited my friend Hamilton at his ceramics studio, popped by another store to pick up a couple of items, then (on Hamilton’s advice) grabbed lunch at the The Grind Café.
I must say that Hamilton was spot-on. My wrap was delicious!
Just what I needed to fuel another POTA activation, right? Right!
After lunch, I drove to Table Rock Fish Hatchery. The weather was ideal and the leaves were beginning to show color.
At our home in the mountains, we were almost at peak leaf color, but the fish hatchery site is much lower in elevation. The weather was simply ideal.

IC-705 Firmware Update
Many thanks to Uli Zehndbauer who notes that Icom recently released a new firmware update for the IC-705.
Here are the details/notes about this firmware version from Icom:
Changes from Version 1.27
– Displays the Receiving (or Transmitting) route icon (RF or TM: Terminal mode) on the RX History Log and QSO Log
– Displays the Receiving (or Transmitting) route icon (RF or TM: Terminal mode) to the chunk information in the QSO audio file
– Displays the Receiving route icon (TM: Terminal mode) to the following screens;
RX HISTORY screen
GPS POSITION (RX) screen
QSO audio, PLAY FILES screen
QSO audio, FILE INFORMATION screen
– Improves the WLAN access point list so that you can delete the connected or saved access points
– Improves the CI-V command 1F 01 (DV transmit call sign) so you can set only the “UR” call sign without the other call signs.
In the past two weeks I’ve received a number of video links from QRPer readers who are featuring CW activations in their YouTube videos.
First up is Steve (K9NUD) who has started a new channel featuring his CW activations primarily using a cootie/sideswiper. Steve is doing something I wish I had the time to do which is add CW closed captions to his videos. This makes it easy to follow along. Check out this video:
Jonathan (KM4CFT) recently noted in the comments of my YouTube channel that he made a video of his third ever CW POTA activation. I had to check it out and am glad I did. You get a very good idea of what it’s like on the air as a CW newbie. In other words: not that bad at all! Incidentally, when I looked up Jonathan on QRZ, I discovered we have a mutual friend in Zach (KM4BLG).
Keep up the great work, Jonathan!
Chris (KD2YDN) sent me a link to the following video on his new YouTube channel. In the video I actually get to hear what my signal sounded like during his SOTA/POTA activation. He certainly captured some amazing morning scenery and a gorgeous sunrise from Westkill Mountain:
I think you should consider checking out these videos and subscribing!
The ARRL Handbook 100th Edition
The ARRL has announced pre-orders for their new ARRL Handbook. I feel like everyone should have a copy of the Handbook. It’s simply chock-full of useful information–much of which is simply timeless. I still reference the 1994 handbook my buddy Mike (K8RAT) gave me shortly after I got my license in 1997. I feel like it’s important to have reference material like this in paper.
As a side note, I’ve been to a number of shortwave radio broadcast transmitting stations and at each one of them I’ve seen the ARRL Handbook on the Chief Engineer’s shelf. Lots of great radio principles inside.
The book is $80 on pre-order. That’s a lot for a book, but it’s also a LOT of book!
Here’s the announcement from the ARRL:
We have arrived at a milestone. The 100th edition of The ARRL Handbook for Radio Communications is here: Handbook 100. How do you celebrate the most widely used one-stop reference and guide to radio technology principles and practices? By continuing to fill the pages of another edition with the progress and achievement of radio amateurs. Handbook 100 is written for everyone with a desire to advance the pursuit of wireless technology. Here is your guide to radio experimentation, discovery, and innovation.
What’s Inside
Each chapter is filled with the most up-to-date knowledge representative of the wide and ever-expanding range of interests among radio amateurs. There are practical, hands-on projects for all skill levels — from simple accessories and small power supplies to legal-limit amplifiers and high-gain antennas.

Also, inspired by your post, I dragged my OM0ET magloop up a mountain today for a POTA activation. I used a 3D printed tripod adapter of my own design that allows me to mount it on the collapsing legs from the Buddistick Pro. It makes the whole package a lot more manageable and light weight than carrying a camera tripod.
I had a successful activation of K-4454 on 20 meters, and thought you might enjoy some photos of the setup:
I’ve uploaded the design to Thingiverse at this address:
Wow! Thank you Jonathan. That short demonstration prompted me to order the K7QO noise bridge kit from QRPguys this morning. In fact, I plan to build this and keep it with my loop antenna as it’ll pair so nicely with my IC-705 and TX-500!
Thank you, also, for sharing those 3D files! I love that field setup at K-4454!
