The Sudden Storm direct-conversion receiver kit is a simple, easy-to-build radio based on a design by the Rev. George Dobbs, G3RJV, and presented in Practical Wireless magazine. W1REX’s original QRPme version of the circuit board is designed to fit on top of a tuna can. It’s a great companion for a Tuna Tin-2 transmitter, designed by W1CER and featured in QST in the mid-1970s. If you’re interested in a Tuna Tin-2 transmitter kit, please contact us at 73RadioRow@gmail.com. There are no toroids to wind, and reception is crisp around the Storm’s 40-meter CW crystal frequency – 7.040 MHz, the QRP calling frequency. “With no coils to wind, a minimum of parts and a step by step pictorial builder’s guide, this kit is ideal for beginners and experienced builders alike,” the Storm’s manual notes.

Everything you need to know about antennas – from wires to beams to transmission lines to fixed and portable systems and a ton more - can be held in one hand with this soft-cover 22nd edition of the ARRL’s renowned “Antenna Book for Radio Communications”. Except for some scratches, a rough edge and a dog ear on its cover, this book is in like-new condition. Due to its unorthodox page-numbering convention we’d only be guessing at the page count. But in its large format it weighs a bit over four pounds. (Remember: FREE SHIPPING). Its table of contents, shown in accompanying photographs, covers almost three pages. If you’d like to have all of your antenna-reference data consolidated in one place, perhaps this is your answer. Accompanying CD is not included.
In 1996, Doug Hendricks, KI6DS, and Wayne Burdick, N6KR, came up with a simple 40-meter milliwatt CW transceiver that was to be the marquee item in a Dayton building contest. After dozens were assembled and put on the air, there was such a demand for the NorCal 49’er it was, for a while, a very popular NorCal kit for sale around the world. Why the 49’er? It was a 40-meter CW transceiver capable of running off a 9-volt battery. This is the original PC board. You provide the parts. See the manual at http://bit.ly/2EZCBJd. The tale of the tape: Runs on any DC voltage from 7 to l2; power output of roughly 250mW at 9 volts, 500mW @ l2V; VXO covers about 5kHz (7.037 to 7.042 with 7.040MHz crystal); Full QSK - really helps when you're using such low power; very low current drain: 10mA receive, about 70mA transmit (@9V); Only one simple alignment step, and NO toroids.
“101 Shortwave Hookups” is a Lindsay Publications compilation of shortwave-amateur radio band receivers that appeared in “Short Wave Craft" / "Radio and Television" magazines, published between 1930 and 1941. Particularly interesting is the vast array of circuits employed. For examples, the Pantaflex, Dou-Amplidyne, Twinplex, T.R.F., Triplex, Myers, Electrodyne, Doerle, Oscillodyne, plus many regenerative, super-regenerative, super-regnode and superhetrodynes. It is 72 pages long, with schematics and building details throughout. For a full snapshot of “101 Shortwave Hookups,” review its Table of Contents in the accompanying illustrations. Lots of circuits are represented, as well. This book is in very good condition and would be a great reference book for the radio amateur and SWL’s library – a “must have” for the fan of wireless nostalgia.
With the increasing popularity of vintage transmitter operation, here’s a Grid Block Keying Adapter that allows CW operators who love their solid-state keyers to use them with many tube-based rigs with low negative voltage keying. It was produced in the late 1990s by Jackson Harbor Press with the caveat that it will not work with rigs having cathode keying (positive high voltage). If you have a vintage, commercially-manufactured transmitter or transceiver and aren’t sure how it is keyed (grid block vs. cathode), Google the name and brand of the rig. The specifications should tell you which keying circuitry is in your radio. The kit offered here is in its original packaging and includes documentation. It is suitable for beginners with some soldering experience. This version of the Jackson Harbor Press Grid Block Keying Adapter is believed to be no longer in production.
“Ham Radio” was a wildly popular monthly magazine that was published from 1977 to 1983. It was particularly liked for its simple explanation of complex subjects and its nearly wall-to-wall presentation of homebrew projects. 73 Radio Row was fortunate to find a copy that we are able to offer website visitors at a much more manageable price than required by commercial dealers. Plus FREE SHIPPING. This box set is complete, with high-quality reproduction of the magazine’s pages. Although the cellophane packaging has been removed from the jewel box, we have tested each disc and can confirm all are functional. If you’d like to revisit “Ham Radio,” or would like to see it for the first time, here is your chance.
Jerry Sevick, W2FMI (SK), has been universally viewed as one of the world's experts on Baluns, Ununs and transmission lines. "Understanding, Building, and Using Baluns and Ununs", circa 2001, is viewed as the authority on these devices. The subtitle is "Theory and Practical for the Experimenter." This CD not only gives the theory of how baluns and ununs work, but shows the reader how to make them. Why spend on a commercially-made device when you can wind your own? Sevick explains how. This book is the successor of Sevick's "Baluns and Ununs." This CD has been tested on a PC and works perfectly. A must read!
“The Hot Water Handbook, HW-8 Recipes” came out in 1985, being compiled and edited by Fred Bonavita, W5QJM (SK). Its 21 pages cover a range of improvements and modifications to this popular multiband QRP CW transceiver from Heathkit. Included are instructions for anti-audio motorboating, installing an Inboard Active Audio Filter, Four Watts for the HW-8, 30 Meters for the HW-8 and lots more. An accompanying image shows its Table of Contents, giving the full picture. The list of writers includes some of the biggest names in QRP in that era. The plastic cover and binding was in such poor shape, we re-packaged this historic manual into fresh plastic sleeves for protecting each page. We have also included a second copy of the manual’s cover if the owner would like to affix it to the cover of the folder. 73RR is very happy to have found this copy and may be obtaining several more.
This 2-CD set features complete WorldRadio Online editions for 2009 and 2010. The pages are in crisp, clear PDF format and separated by month. The 2009 CD is a collector’s item by virtue of the fact that is shows the transition from WorldRadio to WorldRadio Online – from a black and white paper publication to colorful digital. A look at the CD jewel box cover shows the variety of aspects of amateur radio covered in these 24-months. Combined, there are more than 1,000 pages by our conservative estimate. Each month is complete, cover to cover. They have been tested and are full functional. WorldRadio and WorldRadio Online are no longer being published. Not only is this CD set a bargain, but a collector’s item, as well.
“VHF/UHF Handbook” (1998) is a Radio Society of Great Britain (RSGB) publication edited by Dick Biddulph, G8DPS – an excellent desk reference for the new radio amateur and the seasoned VHF/UHF veteran. Just getting started on the frequencies above 50 MHz? This book is an excellent place to start. VHF/UHF propagation? Equipment? Antennas? All are covered. Also: EMC (ElectroMagnetic Capability), late ‘90s Data Modes, ATV, Satellites, Repeaters, Test Gear and Station Accessories. There are circuits for experimentation, VHF/UHF antenna pattern plots, a smorgasbord of station accessories and much more. It is beautifully indexed, making zeroing in on a topic of interest a snap. The cover has a bit of wear along its edges. But otherwise, this copy is in like-new condition. Here is the VHF/UHF operator’s chance to get this excellent RSGB publication without having to deal with shipping charges or money exchange.
Whoever titled "The New Shortwave Propagation Handbook," must not have taken into account that books on basic theory have long shelf lives. This book was new 20+ years ago but a 1995 time stamp disqualifies it as "new" today. The concepts discussed, though, are solid in 2016. Authors George Jacobs, W3ASK (SK), Theodore J. Cohen, N4XX, and Robert B. Rose, K6GKU (SK), combined their vast knowledge into a very robust desk reference. Check out the table of contents in the accompanying photographs. This copy is almost new condition inside and out, including a solid binding.
The Hamfest Buddy is an oscillator-transmitter kit developed by the late Dave Ingram, K4TWJ (SK), longtime “World of Ideas” and “QRP” editor at CQ Amateur Radio magazine. In its August, 2005 edition, he featured this circuit that can produce 50 to 60 milliwatts of RF on the 40-meter CW band with a 9-volt battery. A 7.040 MHz crystal is provided with the kit. At 12-volts DC, the ‘Buddy can put out 250 to 400 milliwatts, which is certainly sufficient for making contacts on the air. Ingram’s clever concept includes instructions for how to use the rig as a BFO (beat frequency oscillator) allowing you to copy CW and SSB with your inexpensive shortwave receiver. Dave included an earphone for use with your SWL receiver. A copy of the CQ article will be included with this kit. The Hamfest Buddy was very popular at the time and is quite rare today.
Here is a great trail-friendly field accessory: the All Weather Radio Log Book for Portable / Mobile operators. From Andrew Stevens Associates ASA) in 2007, it is waterproof , rugged and almost indestructible. You can write in it with pens, pencils, markers – just about anything. Once the QSO data is logged, your notes are there forever. No running ink or erasure. There are 7 QSOs per page and about 50 pages. We’ll do the arithmetic: Room for about 350 contacts. The All Weather Radio Log Book measures just 5-inches by 3-inches. It is three-eighths of an inch thick and spiral bound. It will easily fit in your hip pocket. Entries include DATE, TIME ON, CALL , FREQ, TIME OFF AND COMMENTS. This is one-rugged amateur radio log that will is the essence of utility for the radio amateur who likes to operate outdoors.
We’d never seen this one before, but “Using Your Meter”, by Alvis J. Evans, is a really nice desk reference as a tutorial on how to get the most out of your digital volt meter (DVM) and Volt-Ohm Meter (VOM) multi-testers. It covers the basics in both theory and practical applications, focusing on voltage, resistance and current. An accompanying photograph shows the breadth of its contents. And, as you’ll see, it describes uses for the radio amateur and DIY’ers who delve into home appliances, lighting, automobiles and tool-control circuits. This copy is in like-new condition and is 176 pages in length. Evans is a former associate professor of electronics at Tarrant College in Fort Worth, Texas.
