Many thanks to Paul Evans, who shares the following short radio documentary from the BBC World Service:
The end of the Cold War in 1989 spelt the demise of a little-known, but surprisingly popular sport behind the Iron Curtain – high-speed telegraphy competitions. With the help of two of Czechoslovakia’s best former Morse-coders, we revisit the inaugural World Championship in Moscow in 1983 when the Soviet Union rolled out the red carpet for teams from across the Communist bloc. Ashley Byrne reports. The programme is a Made-In-Manchester Production.
These files are kept up-to-date on a daily basis. You’ll see that this currently lists memberships of 69 different clubs, including the vast majority of QRP clubs, a surprisingly high number.
One exception: G-QRP [who] told various sites that used their (previously open) membership list to cease using it.
Dave Benson K1SWL, founder of the renown Small Wonder Labs, listened to you and has designed a 40 meter version of his winning Hilltopper design. Four State QRP Group is honored to have been selected to kit the new transceiver. The Hilltopper is a high performance CW transceiver for the 40M meter band. It is the perfect solution to your portable operation needs – small, lightweight, wide 40 meter frequency coverage and low current drain, extending the life of your portable power source. The receiver is adapted from K1SWL’s SW+ Series with minor modifications. The front-end circuitry was revised to replace the now-vanished 10.7 MHz IF transformers. The receiver output is suitable for headphone use.
The transmitter strip is a proven design using three BS170 transistors for the PA. The frequency source for both transmitting and receiving is a DDS VFO employing a Si5351 PLL module. Control for the rig is provided by an Atmel ATmega328P. This runs both the frequency control and the full-featured CW keyer.
A custom silk-screened PCB enclosure is included with the kit. No drilling or cutting required!
There are two pre-installed SMT ICs on the board, but the remainder are ALL THROUGH HOLE parts, and all jacks and connectors are board mounted, the combination making this kit very easy to assemble with no external wiring needed.
Looks like people are catching QCX Fever! What an amazing Radio!
I agree, Pete! It’s simply amazing how self-contained this transceiver is. I like the fact that the kit is through-hole and that the board appears to be high quality. I will soon have one on order. This will be a fun winter project! Thanks for sharing, Pete!
The “QCX” is a 5W, single-band, high performance CW transceiver kit with WSPR beacon, and built-in alignment/test equipment. It is available for 80, 60, 40, 30, 20 or 17m bands. See below for the long list of features! This is a kit of parts that you assemble yourself. There are NO surface mount components to solder (two SMD ICs are already factory pre-soldered). We do not currently have any enclosure available for this kit, it may be something we investigate in the future.
Features
Easy to build, single-board design, 10 x 8cm, all controls are board-mounted
Professional quality double-sided, through-hole plated, silk-screen printed PCB
Choice of single band, 80, 60, 40, 30, 20 or 17m
Approximately 3-5W CW output (depending on supply voltage)
7-16V recommended supply voltage
Class E power amplifier, transistors run cool… even with no heatsinks
Thank you for the tip, Pete! That’s an amazing amount of transceiver for the price. You’re right, I believe even a new kit builder could build this transceiver.
Here’s a pic of the new “Station Base” for the portable torsion bar key. The rubber feet unscrew and can then be attached to the key base. It’s really solid on the desk but the whole thing only weighs about 12oz.
Bencher, Inc. of Antioch Illinois announced the sale today of the Bencher Amateur Radio product lines to Vibroplex, LLC of Knoxville, Tennessee.

Jere Benedict and Bob Locher wish to express their gratitude to the amateur radio community for its interest and support since the sale of the first Bencher amateur radio products in the early 1970’s.
The North GA QRP Club gang have added a new annual field event to the amateur radio contest calendar–a field event with an unusual twist. The Peanut Power Sprint is this Sunday, September 29, 2013, from 2000Z to 2200Z.
What’s unusual about this event is that it is open to those operators running QRP, those running more than QRP power, those operating at home, and those operating in the field. Participants will be competing against only those who are in the same class. In addition, both CW and SSB operation are allowed and encouraged.
Operations are allowed only on 15, 20, and 40m. The recommended 40m CW frequency is 7.060MHz, not the usual QRP calling frequency.
Those operators with a “Peanut Power Number” can work anyone; those without a number may work only those with numbers. It’s not too late to request a “Peanut Power Number”.
Personally, I’m looking forward to be operating as Peanut Power #105, “Salted” (5w, portable).
One of the highlights of my trip to the Dayton Hamvention last year was attending evenings at Four Days in May (FDIM), a QRP convention sponsored by the QRP ARCI that rather conveniently coincides with the Dayton Hamvention, which I try to attend annually. Though scheduling makes it difficult for me to attend all of FDIM’s daytime presentations, the camaraderie and innovation one discovers at the evening sessions is wholeheartedly worthwhile.
Last year, I snapped quite a few photos at FDIM which I planned to post following the Hamvention. Unfortunately, shortly after the Hamvention, my laptop began displaying signs of an early demise. In haste, I archived my photos on a portable drive, where they remained buried for a year. I just rediscovered this photographic treasure, and thought I’d share it with readers; looking through them rekindled my enthusiasm for FDIM 2013, which starts next week!
A quick look at FDIM 2012
A great characteristic about FDIM is the array of QRP products offered by QRPers for the community. More often than not, these products are fairly priced, and often in support of the QRP community rather than major profit-making ventures.
For example, the North Georgia QRP Club produces affordable wood stands for QRP rigs. They’re incredibly simple, but fully finished and beautifully designed, just the thing to prop up your QRP portable at the right angle for desktop use.
Speaking of wood products–one vendor last year featured an amazing array of wooden paddle pieces and even custom wooden tuning dimples (spinner knobs) for the Elecraft K2 and K1.
As you can see from the photos, each piece is perfectly finished and has great character, as one might expect of real wood.
Dennis, being a hard-core QRPer, trekked with ham gear in tow; he brought his kits to FDIM:
There were a variety of keys and paddles to be seen, of course; offerings range from the home brewed to gorgeous Italian Begali designs:
One paddle that really caught my attention was QuadraBug, a creation of WB9LPU. What makes this gem stand apart from other “Bugs” is that not only will it form “dits” automatically, but it also forms “dahs.” Truly, an amazing work of engineering. I searched the web for a video of the QuadraBug in action, but found nothing. [UPDATE: Thanks, Yan for finding a video! See video below.] This year, I’ll take a video if I’m fortunate enough to see it again.
Home-brew galore
There were an amazing number of home-brewed projects on display, and even a home-brew contest. I didn’t capture photos of them all, but I did manage to snap a few.
One that really caught my eye (being a shortwave receiver enthusiast) was David Cripe’s (NM0S) version of Hutch’s Radio. The original Hutch’s Radios were built by US and British POW’s in WWII. Built in canteens, often from confiscated parts, these radios gave POWs hope by allowing them to tune in the outside world, via the BBC WS and Voice of America. In the spirit of the original, David challenged himself to build his version prior to FDIM, with original parts of the era, and in “secrecy.” Secrecy? As many of the components had to be purchased from suppliers on eBay, David tried to intercept all of the incoming packages without his wife noticing. His success was brief–alas, his wife discovered the mission–but fun; still, the end result was a very cool piece of historical recreation with a humorous story to match:
Of course, FDIM featured loads of QRP transmitters, receivers and transceivers; here is Dwayne’s (AK4P) 40 meter transceiver, built in a SPAM container:
Terry Young, K4KJP, built a very cool pocket 20 meter transceiver in an Altoids tin:
And Alan Shapiro, NM5S, should have won a prize for the most compact set of CW paddles. These paddles are so small that they can be clamped onto your log book. Much to my surprise, they were amazingly easy to use, and would be a great addition to any field-portable radio:
FDIM 2013
If FDIM 2012 is any indication (yes), this is a mere sampling of the stuff you’ll see at Four Days In May 2013. I encourage you to attend: if nothing else, make a little time either Thursday, Friday or Saturday evening to visit the evening displays at FDIM–they’re free and open to the public.
If you can’t attend, I hope you’ll earmark your calendar for a future date. I do plan to bring my camera again this year and will share some photos. Hopefully, I’ll post them a little earlier this go-around!
Hope to see you at FDIM and the Hamvention. For the third year in a row, I will be representing my charity, Ears To Our World (ETOW), at an inside exhibit at the Hamvention. We should be in booth 601 in the East Hall. Please feel free to stop by and introduce yourself! (And if you feel so inclined, you can even donate a few bucks to our worthy cause.) See you there–!
And I thought my buddy, Mike (K8RAT), was being gastronomically adventurous when he made a homemade single-lever “sideswiper” with a steak knife! Imagine what might happen if the steak knife meets up with this:
QRP radios, product announcements, reviews, news and more. Low power amateur radio fun!
