The best of his antenna and feed-line analysis, debunking and overall expert advice were wrapped up in “Kurt Speaks Out,” by the irascible Kurt N Sterba, longtime monthly columnist for the late WorldRadio magazine. A world-renowned aficionado, Kurt’s somewhat obscure book, published in 2006, covers topics ranging from the resonant-feedline dipole and shunt-fed verticals to how to use a tuner and in-depth analysis of SWR. It was obtained directly from Kurt himself several years ago and has a vague coffee ring on its front cover. Perhaps his? Other than minor wear, it is in excellent condition. At 105 pages, it’s a great addition to any amateur radio library. Click here for more information.

The Tuna Tin 2, a 40-meter QRP transmitter on a circuit board atop an empty can of tuna, was designed by Doug DeMaw, W1CER (W1FB SK), and became all the rage in the QRP community in 1976. That’s when it appeared as the cover story in QST. At the time, all of the parts could be found at RadioShack©.. As RS inventory changed, several of the parts were no longer available. Years ago, the Fort Smith QRP Group offered QRP’ers a full TT2 kit – sans tuna can and 40-meter crystal. Power output is about 750 milliwatts.

The Arizona QRP Club’s Black Widow Paddle was designed and produced by Jerry Haigwood, W5JH, and became a very popular kit in the Morse community about a decade ago. No longer in production, 73 Radio Row has found one that – with a thorough cleaning and reassembly – looks and works like brand new. It is made of brass with a 3 inch x 3-inch base. It uses computer-controlled machined parts for excellent fit and accuracy. It has both spring and magnetic return force. Its arms ride on precision ball bearings. The contacts are silver plated for low resistance. Bearing tension, contact spacing, and magnetic return force are all adjustable. Click here to see the manual.
This MFJ-816 QRP/QRO HF SWR-Wattmeter was manufactured by MFJ Enterprises decades ago. Its look is old school; not much like MFJ products today. It is a perfect companion for antenna tuners that don't have SWR and power output reading ability. The '816 covers 1.8 to 30 MHz, showing Forward and Reflected power and SWR. Its front panel push button toggles the unit between FWD/SET and REF/SWR via a classic MFJ meter. It will handle up to 300 watts, but is also calibrated on a 30-watt scale. Standard SO-239 coax connectors are on the back. A copy of the original instruction sheet is included. It has been thoroughly tested and performs beautifully.
