Many of you have been asking about the SP4 paddle and when it might be in stock once again.
I’m happy to not that CW Morse is working on a large production run of SP4s right now and have inventory at time of posting. I spoke with CW Morse and they noted that if you find that they’re out of stock, check back again soon as they’re finishing batches of them every few days.
After a rainy and windy Friday, the weather was expected to improve a bit the next day. The temperature was still forecasted with around 0 °C / 32 °F, but no rain was expected. So, my friend Jochen (DG1PSI) and I thought we could operate outside. We have chosen a summit called Bernhardus. The summit is next to “Kaltes Feld” on the opposite side of the valley, where I was a some days before. With an 1.2 km / 0.75 mi trail and an ascent of 124 m / 440 ft, it is not the hardest summit around.
We had an appointment for 10 o’clock. The parking lot was still empty at the time, but the weather seemed a bit more difficult than expected. We have asked some other members of our local ham radio club if they want to join us. But surprisingly, no one wanted to get up early on a Saturday morning, hike and operate a radio in freezing temperatures.
As mentioned, the summit was near “Kaltes Feld”, on the opposite side of the valley. You can see the SOTA activation zone of “Kaltes Feld” on the left, the glider airfield in the middle and some miles in the background another SOTA summit called “Stuifen”.
The peak was easy to reach and invites enjoying the beautiful view.

ATS-20 configured with Zachtek “Flea” CW transmitter
The ATS-20 in HF CW Transceiver Mode
by Bob Houf (K7ZB)
I picked up an ATS-20 last summer and played with it on SWBC and the ham bands but found the telescoping whip antenna to be marginal.
The unit I purchased from Amazon turned out to be solid: no problems have surfaced after 9 months of intermittent listening. By default, I have enjoyed it primarily listening to FM in my office.
When I used my long wire antenna, the performance on shortwave greatly improved – easy copy of DX and the value of the receiver began to impress me.
Recently I came across a Swedish ham who co-developed a line of radios covering a broad range of WSPR and associated designs built to a very high standard.
Already having a WSPR setup I was intrigued by a very low power CW transmitter that Zach co-developed with KB9RLW which puts out 300mW on 40, 30 and 20 meters at a price point that is less than the ATS-20, and – most interestingly – the design of the radio allows it to work in transceive mode with the receiver by providing a T/R switch when used with the proper SMA-BNC cable arrangement.
I bought a “Flea” and configured it with my ATS-20 then used an external antenna tuner to make sure the transmitter had close to a 1:1 SWR. The “Flea” advertises that it is robust to high SWR and looking over the schematic that is evident, but for the sake of a trial I went with the ATU.

Many of you have reached out this week congratulating me on the article that features my work in the April 2023 issue of QST. Thank you all for the kind words.
I’m truly honored that QST would feature my work here on QRPer.com and my YouTube channel in their pages. Steve (K5ATA) wrote a very gracious article, and frankly, I don’t know what to say other than thank you!
I’d like to thank all of you, readers, for making QRPer.com what it is today with your contributions, guest posts, field reports, hints & tips, and words of encouragement to others in the comments section. I’m honored to have even played a modest role in your radio journey, and your feedback and contributions have taught me so much, which, I feel, has made me a better field operator.
On Sunday, February 19, 2023, I felt like I was moving in slow motion.
The previous day started early and I fit in a long hike, a SOTA/POTA activation, and a second park activation. Round trip driving time was about four hours, but it was worth it. I had an amazing time. Those field reports will be posted in the upcoming week.
The previous evening, I also participated in a live stream and after hours chat with Josh (KI6NAZ) on his amazing Ham Radio Crash Course channel. It was loads of fun, but I was up pretty late after a long day.
Sunday morning, I was feeling it and couldn’t decide if I wanted to do a POTA activation on the drive back to the QTH. In case I decided to, early that morning, I scheduled an activation at Table Rock Fish Hatchery with a very wide activation window. I often don’t have enough mobile phone service to self-spot at that particular site, so I decided that if I was able to make the activation, it would cover me.
I wasn’t even ten minutes into the drive home when I decided to go for the Table Rock activation, of course! I seem to never be too tired for some POTA!
I did make up my mind in advance to try to activate the park on 17 meters because 1.) there was a CW contest that weekend, and 2.) I wanted a more laid-back activation instead of a pileup. I figured 17 meters would have some activity, but not to the degree of the non-WARC bands.
Table Rock State Fish Hatchery (K-8012)
I decided to record the entire activation from set-up to pack-up so I grabbed the action camera from my radio bag in the passenger’s seat and started recording as I pulled into the site.
I had a lot of gear in the trunk/boot of my car–more than normal–because I brought along quite a few radio packs to show on the HRCC live stream for this trip.
I grabbed the Penntek TR-45L and PackTenna random wire. I thought they would pair nicely for a casual POTA activation.
I wasn’t sure if I should write a report about this activation. It was “average” at best. But I thought it might be worth to share that not all activations are perfect, with stunning views in an enjoyable environment.
Intro
I am a relatively new ham and completed my first exam in mid-2019. It took me a while to get my head around all the things that the new hobby is offering. My first successful portable activation was in May 2021 on the SOTA summit Michelsberg (DM/BW-855) – here is a picture of my most recent activation some weeks ago:
This first activation was in the middle of the Corona pandemic. The good thing during the Corona time was certainly the possibility to work from home. Before Corona, I did commute roughly 65 km / 40 mi (oneway), which took me in total 2–3 hours daily. During the first two years, I was in the office two times. In the third year, I was there more often, maybe once every two months.
Two weeks ago, my employer announced a “return-to-office” policy, so the “sweet life” was coming to an end.
After the first disappointment, I thought that this may offer me the chance to work portable at new locations. The next SOTA summit is around 20 km / 12 mi away, but a POTA park begins 2 km / 1.2 mi from the office at the pin in the map below. The park is basically all the green wood in the center of the map.
That comes in very handy, as POTA, with the possibility to operate next to my car, does make it easier than hiking in suit and tie to a SOTA summit.
The Nature Park Schönbuch, POTA DA-0008, located southwest of Stuttgart, is a wooded area of 156 km² / 38,000 acres. In 1972 in became the first nature park of the federal State of Baden-Wuerttemberg. The park is an important recreational area for the region.

Activation
Right at the beginning of the park, when coming from my office, there is a parking place and next to it a clearing with a fireplace. I thought that this would be a perfect spot for my activities. Weather was cold and windy on my first “return to office” day, I did not expect too many people to be there.
After working and reading the article about the 2023 QSO Today Virtual Ham Expo, I decided to leave the office early at around 4pm and started my activation.
The parking place at the park was pretty empty, just one old car with four lads in it and doing whatever lads are doing in the woods. I have a 16-year-old son and have given up trying to understand what boys at that age are doing.
The spot was OK, but not as perfect as I had thought. It was in a trough surrounded by large trees. In addition, it was wet, cold and windy.
Due to the wind, I have decided against the 10 meter / 33 ft pole and used the PAC-12 again.
The actual activation did not go as smoothly as my previous one. It might have been due to the time, and afternoon during the week, or the topographical conditions. With a small foldable seat and a tiny desk made of a trunk and a brick, I operated for 40 minutes.
In total, I made 16 QSOs; 10 on the 30-meter band and 6 QSOs on 20 meters.
Although I made a successful activation of the Nature Park Schoenbuch, DA-0008, I think I need to change my plans. Being in the office and therefore close to this park more often in the future, I will be more picky in terms of weather and location. The park has way more to offer than a wet and cold meadow in the middle of the woods. I will look for better weather and locations, such as the following – I just need to find those places.

T-T R4020
One of the least expensive radios I’ve ever purchased is my TEN-TEC R42020 two-band CW only radio. I believe I paid $120 for it (shipped!) a couple years ago and it sat on my shelf unnoticed for months until I took it on a POTA activation last year.
Here’s the admission: I really love this little radio!
It is not a feature-rich radio, and the sidetone sounds like a 1080s handheld arcade game, but it works a charm! The receiver and audio are fantastic and it sports two of my most useful POTA/SOTA bands: 40 and 20 meters.
What’s not to love?
POTA time!
I had an early morning doctor’s appointment on Thursday, February 23, 2023. As a little reward for doing my annual physical I decided to add a POTA activation to my morning. This was a last minute decision, so only a couple minutes before leaving the house that morning, I grabbed my TEN-TEC R4020, the Chelegance MC-750, and my Spec Ops Backpack (filled with all other field accessories), and I hit the road!
I chose the MC-750 that day because I needed an antenna that could be configured to be resonant on 40 meters since the R4020 has no internal ATU. That and I couldn’t remember if I’ve configured the MC-750 for 40 meters in the past. I know I’ve deployed the MC-750 with the 40M coil, but I think I may have used an ATU to match it.

The search for the best portable speaker for ham radio.
Welcome to the end of my exhausting search for what maybe the best speaker for portable ham radio.
My list of requirements was short: it had to be small, amplified, and have an internal battery.
But most importantly, it had to have a AUX input.
The last requirement shortened the list very quickly. Most speakers today that have any quality of build are lacking in the old fashion AUX connection.
I tried a minimum of six speaker and even tried making one of my own. Rich sound quality was not most important factor to me. Let’s face it: we are not listening to the Beatles.
Now we are going to focus in the two that made the cut. On the bigger side was the JBL Charge 4. Rugged? Yes. Battery life? Great. Size and weight? OK. Take it from the car to the picnic table ok? Yes. Throwing in the pack for a SOTA or a long hike? Not the best choice.
Case is made of aluminum all-around including the speaker grill.
External features are:
power switch,
USB charging port,
micro SD card slot,
and the must-have AUX port for connecting to my KX3.
It also has external rubberized volume control.
For those that may need bluetooth it has that also.
All in all, it is super rugged unit with great battery life and small for my QRP go kit. The only thing that comes in the box is the speaker and usb charging cord.
I hope my findings help others in search of a portable speaker.
Thank you for sharing this, Mike. I’m often asked about the portable speaker I use in the field. It’s a Sony SRS-XB12, but the only good source of them is eBay because they’ve been discontinued for so long.
This Anker speaker seems to be the same size and sport the same features of the Sony, at a slightly lower cost. I’ve also had very good luck with Anker products in the past (I’ve had some of their ear buds and several of their battery banks). In fact, I’ve just ordered this speaker because the battery life is also much better than that of my Sony speakers. I’ll plan to take this to the field and include it in my activation videos–I’ve give the Sony speakers to my daughters.
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!

A completely under-prepped SOTA & WWFF activation which turned out to be perfect
In preparation for a tough conversation a good friend once told me: “You know what, just walk into the fire. If you have bad news to deliver, don’t sugar coat it and do it right away. You’ll be fine.”
“Just walk into the fire.” I believe this can be applied to many other situations in life. While I would consider myself to be well-prepared on most trips, hikes and activations and getting a lot of joy out of optimizing my kits I try to stay open-minded. Imagine the things you would miss out on if you wouldn’t be spontaneous or only do things while fully prepared and 100% safe – even if it means taking risks.
The QCX-Mini silently drying after a successful activation
Last Wednesday, I kind of walked into the fire. Not fire as in fire-fire but fire as in Latvian winter storm. In general this wouldn’t be such a big deal had I brought the right clothes, gear and shoes to my short business trip to Riga.
Due to very strict luggage restrictions I could only bring one small backpack for three days. Inside I had enough room for a laptop, washbag, spare clothes and the compact QCX-Mini Kit I built for exactly these occasions. I was wearing sneakers and jeans. At this point I had not planned a specific activation but I wanted at least to be able to operate YL/ & /p maybe 30 minutes from a nearby park – not a problem if you can jump right back into the warm hotel afterwards.
My rental car rocking summer tires in Winter (yes, I was driving veeeeeeery slowly)
During our stay, my schedule for Wednesday morning freed up so I decided to try activating one out of only three SOTA summits in Latvia: YL/YL-003. It turns out this summit is also located within WWFF territory YLFF-0007 about a 1,5h drive from Riga. Big Thanks to Val (YL2SW), Latvia’s WWFF manager, for assisting me with local rules and processing my log. A quick look at the weather forecast showed freezing temperatures, 90% chance of snow, heavy winds and overcast. Many of you will understand why a SOTA&WWFF combo in a rare country could be a small reason not to use the hotel’s sauna on a day like that. Sometimes things just need to get done.
The majestic watchtower on YL/YL-003
I got up early the next morning and was very happy to be able to grab a Bolt rental car from the street and get going quickly. The drive went by without issues up to a point just about 3km away from the mountain (well, 1-pointer hill I should say). The roads were completely covered in snow so I could barely see where I was driving. Latvia is a rather flat country but here it started to get a bit hilly and the tires were certainly not cut out for that. Continue reading CQ From Latvia with Love→
