73 RADIO ROW MARKETPLACE
Leaking C-cell batteries almost spelled the end for this beautiful Ten-Tec Model 1253 multi-band regenerative shortwave receiver. Fortunately our tech department has rehabilitated and improved this “remember when” radio. As accompanying images show, the internal battery compartment has been completely rebuilt, employing easier-to-find AA batteries. It has been thoroughly cleaned to remove any remnant of C-cell leak damage. It is truly portable. This radio has been fully tested and sounds great on either battery or a 12-volt DC external bench supply. Its push-button band switch toggles the radio through the 160, 75/80, 49, 40/41, 30/31, 25/20/19, 17/16 and 15/13 MHz bands. In addition to the main tuning dial, there is a smaller FINE TUNE on the front panel. There are also controls, for RF GAIN, REGEN (regeneration) and VOLUME. There is plenty of audio to drive its internal speaker. There is a provision for headphone use, as well. If you like twisting dials, the Model 1253 for you. As is the case with most regens, there are a lot of things to be adjusted to peak a signal. See the manual: http://bit.ly/2r9S31D

The book is like new and in excellent condition – a must have for every radio amateur with emergency operations in mind.
This American Morse Equipment KK1 Precision Straight Key is from the earliest run of the product in San Luis Obispo, California. As AME owner Doug Hauff, W6AME, said: “Believing that simplicity is elegance in design, I designed this key to be simple: reliable, easy to manufacture, easy to assemble, and with superior function.” In every way, this superb Morse instrument lives up Hauff’s goals. The operator can adjust the contact spacing and tension with easily accessible black knobs, as shown in the accompanying images. This KK1 appears to have never been used. Except some tarnish on the key’s brass parts, it is in like new condition. Here are the KK1’s features, as noted by AME:
Compact, perfectly-balanced design
No mounting required
Fully adjustable, solid feel
Precision CNC machined from 360 Brass and 6061-T651 Aluminum
Tapped hole in base for possible mounting
This is a tremendous find for 73RR and we’re happy to bring it to our showroom. Perfect for trail-friendly CW operation.
With many radio amateurs feeling the squeeze of erecting an antenna on a tiny suburban lot or gated community, antenna guru Juergen A. Weigl, OE5CWL, has written a great book of skywire options for you: “Sloper Antennas – Single and Multi-Element Directive Antennas for the Low Bands.” Accompanying images show the vast array of sloper configurations possible. Check out the Table of Contents. View the back cover to get a Cliffs Notes version of the information in the book’s 236-pages. Its tutorial on the fundamentals is “supplemented by construction guidelines.” The author notes that one of the purposes of “Sloper Antennas” is to fill the gap in amateur radio books – gathering information from many sources and his own expertise. It was published in 2009 and is in near perfect condition with only minor wear on its front and back covers.
Doug DeMaw, W1FB (SK), was perhaps the most prolific writer in amateur radio. “W1FB’s Design Notebook: Practical Circuits for Experimenters” is almost 200 pages of vital reference material for hams who wants to build their own gear and get theory on how it works. It covers diodes and integrated circuits, transistor applications, diode and IC applications, construction practices, practical receivers and techniques and transmitter design and practice. DeMaw was famous for his ability to take complicated subjects and relate them into everyday English. The book contains lots of practical circuits for just about every corner of the radio amateur’s operating position and antenna system. There is, as well, a Glossary of Chapter Terms explaining several dozen of component terms and abbreviations. An appendix reprints some of QST’s best articles on crystal ladder filters. Published in 1990, this copy is somewhat tattered around the edges, but otherwise is in great condition.
From time to time calls have been put out for blank NorCal Sierra band module boards. By some miracle of amateur radio karma, we’ve got one and have a line on a few more. This packet comes with the plug-in board, the protective cover with RX, TX Pre-Mix, XTAL annotations and an area on which to label the board. The buyer supplies the electronic parts. All of the associated hardware is included. The cover is marked Rev. B, 7-9-94, as well. These are pretty danged rare. If you’ve got a Sierra that cries out for more coverage, this is your chance to get it. It appears to have been sealed in a Zip-Loc bag for all these years.
On the ham bands you’ll often hear, “I’m using a Moxon multi-band antenna,” or facsimile thereof. Why? Because radio amateurs around the world have followed L.A. Moxon, G6XN, whose expertise and designs have been widely adopted. “HF Antennas for All Locations”, from the Radio Society of Great Britain, is 260 pages of Moxon's dig into antenna theory and how RF generation is affected by its environment. As the accompanying image shows, its Table of Contents, is divided into two main sections: How Antennas Work and putting Theory into Practice. Moxon provides the math formulas you will use to make an antenna of your own. From end-fed wires and loops to small beams and large arrays, Moxon covers it all. The book is in great condition for having been printed in 1986.
The 15th edition of the ARRL’s “Hints & Kinks” is 270 pages of items drawn from QST’s long-running column of the same name. This edition covers 1997 through 1999 and, for the first time, contains the best of the magazine’s “New Ham” column and “The Doctor is In,” as well. An accompanying image shows its Table of Contents with chapters covering Equipment Tips and Mods to Antenna Systems to Batteries and Generators and Portable and Mobile Stations. It includes a chart of common schematic symbols and lists sources for electronic parts and radio manufacturers. It is an excellent reference book for any radio amateur’s library – whether you’re a newcomer or an old timer. This book is in as near to perfect condition as you can get.
“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 publication of the American Radio Relay League came out in 2011 and is every bit as relevant today as it was six years ago. “Small Antennas for Small Spaces” is a collection of limited-space antenna ideas from well-known amateurs, including the trail-blazing Folded Skeleton Sleeve 40 and 20 Meter Dipole Antenna by QST Technical Editor Joel Hallas, W1ZR. The book is jammed with information including how to get started, antenna configurations, feed lines, SWR, operating modes and RF safety. Also design ideas and projects for VHF and HF antennas you can use inside your home and put together in a weekend, outdoor HF antennas for any property, dipoles, inverted Ls, end-fed wires, loops, verticals, temporary antennas, outdoor antennas for VHF and beyond, compact omnidirectional, directional antennas you can install just about anywhere, and other creative solutions. This copy is in excellent condition – like new.
The wildly popular “ham radio” magazine is long gone from the publishing scene but there are bits and pieces of it around. In this case it’s the “ham radio Anthology: Test Equipment and Repair Techniques.” Information has been culled from the pages of HR, published from 1968 to 1990. They are published in the book’s 200+ pages in the style of the magazine’s appearance. Accompanying photographs show what we mean. There are many entries written by Larry Allen and Joe Carr, who monthly wrote the magazine’s monthly “Repair Bench” column. Tables of Contents are provided in chronological order of articles and by subject. There is also a Clustered Index By Topic. Check out the wide array of valuable information. It is remarkable. This copy is in like-new condition.
"Reflections III" is the world renowned antenna and transmission line reference book by M. Walter Maxwell, W2DU (SK) - with decades of experience in this field. This edition combines all of the content of "Reflections" and "Reflections II" and builds upon it. Accompanying images show the content of this remarkable work. With the subtitle "Transmission Lines and Antennas," it looks at this niche of amateur radio from every conceivable angle. At 420+ pages, it is considered by many radio amateurs as the authoritative work on antennas and transmission lines.
