Field Antenna Survey
Many thanks to Phil (KA4KOE) who shares the results from an informal survey he conducted on the POTA Facebook group. Phil writes:
Tom
I’ve let the survey run for about 3 days on the POTA Facebook group. Sample size was 658 votes. I opted to do a “type” survey and not by manufacturer.
Something tossed in tree and just hoped it would work: 2%
Total: 93%.
Remaining obscure types cut-off below 2% accounted for 7%.
Again, like the poll I conducted previously on radio types, not surprised by the No. 1 spot.
What DID surprise me was #7: I put that selection in the poll types as a joke but 2% of hams throw a wire up in a tree or other support with no forethought and hope it works.
The Palm Pico: Getting a grip!
Many thanks to Terry (N7TB) who shares the following tip:
I have both the single and double Pico paddle and the KX3 mount. After watching you hand hold your paddles, I came up with a way to make small paddles easier to hold. I have attached a photo. It is a small piece of 3/8 ID pipe insulation to make holding the Pico paddle easier.
Have a great trip to Hamvention.

PSK-31 on the Elecraft KX2
Many thanks to Tony (K2MO) who writes:
I have no doubt that you’ve tried this in the field, but thought I’d send along a video I posted on working PSK31 using the CW-to-Data feature on the KX series rigs.
Great job on the latest TR-45 vids!

Just before Thanksgiving, I received an email from Cara Chen at Retevis. She wrote,
I am responsible for the radio review cooperation. We have a SDR radio HS2 for review cooperation. Are you willing to test and write a blog about it?
When I asked her what that meant, she said that she would send me an Ailunce HS2 SDR Radio, if I would review it here on my blog. When I told her that I would be brutally honest in my review, she seemed OK with that and sent me the radio.
What follows is an honest review. It’s not a QST-style review. I don’t have the test equipment that they do, nor did I have the time to put the radio through all its paces. Even so, I did operate the radio on HF and VHF, phone and CW, enough to make the review worth reading, I think.
If you don’t want to read the rest of this review, I can sum it up as follows: The Ailunce HS2 is a fun, little radio, with lots of potential. It’s not perfect, though. The buttons are too small, the display is too small, and the manual needs work. More about all those below.
What’s in the box?
As you can see below, the radio came with a handheld microphone, a DC power cord, and a USB cable.
First impressions:
It’s really small. It’s 45 mm H x 120 mm W x 190 mm D (1.77 in H x 4.72 in W x 7.5 in D)
The carrying case is kind of nifty. If you’re going to operate portable, it’s nice to have.
The extruded metal case include a nice heat sink.
There are a lot of connectors on the rear panel, including the power connector, an SO-239 for HF and VHF antennas, an SMA for a GPS antenna, two USB connectors, an Ethernet connector, and four 3 mm phone jacks.

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?

Lab599 Discovery TX-500 Covers
Many thanks to Mike (KG4MTN) who writes:
Hi Thomas,
I have just received a nice set of 3D screen/keyboard covers from KB7MDB for my TX-500. Along with these covers he included 5 screw-on plug covers. All appear to be nicely made and fit my rig just fine. Cost was $15, which includes shipping. I have the 2-cover set, I believe he also makes a single-cover unit. Mine is black but I think he also makes them in orange. Shipping is very prompt. His Etsy site is Brewer 3D Design LLC.

Ashhar Farhan VU2ESE demonstrated Hfsignals upcoming SDR transceiver – sBitx today at Lamakaan Amateur Radio Meet.
VU2ESE was working on this SDR Prototype for some time now. sBitx is the latest iteration of the popular homebrewer transceiver Bitx series started a couple of years by Farhan.
Keynotes
Raspberry Pi instead of Arduino – No more Arduino Code, sBitx code is written from the scratch for Raspberry Pi.
Jim Stafford, W4QO became a Silent Key yesterday. That news wasn’t unexpected, I had been closely following the North Georgia QRP mailing list these last few weeks dreading the announcement that arrived yesterday morning.
I had known Jim for more than 20 years. We first met in the late 90’s during a Four Days in May event back when the conference took place at the old hotel south of Dayton. I think we hit it off because we both were native Hoosiers, but his infectious enthusiasm for the hobby made everyone want to be around him.
He became my guide into the world of low-power radio and over the following years we regularly renewed our friendship on the air, via email, and in person almost every year during FDIM at Dayton. [Continue reading on Jeff’s blog…]

NG2E activates 7 summits on one December day
Many thanks to Jack (NG2E) who shares this Storymap post outlining his effort to activate seven summits in one day.
Jack notes:
[…]My plan was to activate four primary peaks along the Skyline Drive. I then planned to skip over two peaks–Stony Man and Hawksbill Mtn–as I’ve previously activated these peaks. Once activating Hazeltop Mtn farther to the south, I planned to backtrack and pick up the bonus points only for Hawksbill and Stony Mtn if I had enough time and energy.[…]

Paul’s Page of Ham Radio Groups
Many thanks to Paul (W4/VP9KF) who shares this list of popular ham radio groups. He updates these regularly and the page even dynamically monitors the number of members in each group:
Ryan Flowers W7RLF writes on Hackaday about a simple 7 transistor QRP SSB transceiver
When Pete Juliano N6QW sat down to design a sideband transceiver for the 20 Meter (14 MHz) ham radio band, he eschewed the popular circuits that make up so many designs. He forged ahead, building a novel design that he calls Pete’s Simple Seven SSB Transceiver, or PSSST for short.
What makes the PSSST so simple is not only its construction, but the low component count. The same circuit using four 2N2222A’s is used on both transmit and receive.
Several QRPer readers have reached out noting that Radioddity is now taking orders for the second production run of the Xiegu X6100–they’ve already sold the first batch. Radioddity hopes to ship the first batch soon and the second batch before the end of 2021.
I haven’t heard from other Xiegu distributors yet, but it sounds like early adopters will be getting their units before the end of the year.
I will receive a loaner unit to evaluate and take to the field hopefully within the next few weeks and several readers have orders in the first production run. Scott (KN3A) will be sharing his early experience with the X6100 as well.
Dayton Hamvention 2022 is not just going to be a premier hamfest but a reunion, as organizers prepare for the first gathering at the Xenia Fairground and Expo Center in Ohio after two years of cancellations.
Hamvention’s general chairman Rick Allnut WS8G said in a phone interview that committees have been meeting and volunteers are committed to making up for the time lost to pandemic cancellations.
Hamvention will be happening on Friday May 20th through Sunday May 22nd with an international reception scheduled on Thursday May 19th. Rick said the registration site is already taking bookings from vendors and inside exhibitors and individual visitors can already buy their tickets. All details are available on the hamvention.org website.
RIck said: “Tickets are all printed and ready to go.”
