73 RADIO ROW MARKETPLACE
This 1957 edition of “The Radio Amateur’s Handbook”, published by the American Radio Relay League, is a snapshot of amateur radio in the year that the first artificial satellite – Sputnik – was launched into space by the Soviet Union. The book's historical significance is that ham operators and shortwave listeners joined government agencies around the world in monitoring the satellite's "beep, beep, beep" transmissions in October, 1957. The handbook gives a great picture of what amateur radio was like at the dawn of the Space Age. This copy is in great shape, given that it is 60-years old. The cover was pulling away from the binding, but our restoration team did a nice job repairing it while preserving the book's authenticity to the era. The binding is stitched and all pages are solidly in place. Accompanying images give a peek into the handbook’s contents and its overall physical condition. Given 1957’s historical significance to amateur radio operators and shortwave listeners, this was quite a find for 73 Radio Row and considered a collector’s item.
Grandad’s Electronics pulled out its poetic license when producing the cover of the manual for its XTAL-1 frequency marker kit. Its shows a Heathkit 100 kHz Crystal Calibrator from its product line of decades ago. In actuality, this kit is a modern design (2008) that is “a very stable crystal calibrator-oscillator kit with harmonic marker signals every 100 kHz from the bottom of HF to well into VHF or higher,” requiring no warm-up time, one reviewer wrote. Click here to read his complete assessment of the Xtal-1. There is one simple modification required of the builder, which is fully explained in its accompanying manual. Parts locations are annotated on its high-quality silk-screened PC board. The builder matches the capacitor marked “C1” on the board to the parts list included in the manual. This kit appears to be no longer in production.
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 Small Wonder Labs FREQ-Mite is a PIC-based Morse read-out frequency counter that was produced by Dave Benson, K1SWL, in the late 1990s. It is an excellent accessory for transceivers with analog tuning. Its maximum counting frequency is 32.76 MHz – covering all of the high-frequency amateur radio bands – 80, 40, 20, 17 and so on. Its accuracy is +/- 1.5 kHz to 25 MHz and +/- 2 kHz at 32 MHz. Send a query asking what your frequency is and it sends Morse audio via an 800 Hz tone. The Morse speed is adjustable from 13 to 26 words-per-minute. The brains of the FREQ-Mite is a PIC 16C621 chip, programmed by Small Wonder Labs. The kit includes all parts and a top-quality printed circuit board. This is a through-hole parts kit. There are no surface-mount components. The package has never been opened and includes a six-page assembly and operations manual. Long out of production, the FREQ-Mite is a rare find, indeed.
NØXAS, of Ham Gadgets, produced a low-power iambic keyer 10 years ago that became very popular. Known as the Super PicoKeyer, it is a QRP classic, that appears to be no longer in production. Versatility was front-of-mind in its design. Its features go on and on:
Low voltage - from as low as 2.5 to 5.5V • Low current - typical sleep current .005 µA, under 1 mA when keying. • Low parts count - build a keyer with as few as two external components • Simple one-button "menu" interface • Works with any dual lever ("squeeze") keyer, single lever keyer paddle or straight key • Dot and dash memories, automatic timing and element spacing • Setup and message entry using your paddle • Auto straight key detect, both memories available with straight key • Speed adjustable from 5 to 60 WPM via menu OR optional speed potentiometer • Dual-Set Speed allows quick QRS/QRQ and return to favorite speed • Adjustable weight • Variable pitch audio sidetone • Selectable Mode A or B timing • Tune mode • Beacon mode with adjustable 0 – 99 second delay • Two message memories, 60 characters each can be chained together • Memory “pause” allows manual insertion of QSO number, RST etc. into message • Paddle switching - select left or right handed operation • Memory and parameter settings retained with power off • Compact, single 8-pin package ideal for standalone use or integration into transmitter or transceiver
This great keyer, with its low-power requirements, is perfect for portable operation.
Off-the-grid guru Mike Bryce, WB8VGE, has put together his most important work in “Emergency Power for Radio Communications.” Its 12-sections cover the gamut of green power, including Solar Power, Charge Controllers and Photovoltaic Systems, Gas, Wind and Water Generators, Battery Systems and Storage, Inverters, Station Instrumentation, Safety, Emergency Practices, as well as Wire Size Tables and Power Connectors. Also, you’ll learn how to build a gasoline-powered DC generator, battery charge controller, low-voltage disconnect, an automatic sealed-lead-acid battery charger, and more. It was published in 2005 and covers the how-to and principles of emergency power operations applicable to this day. The book is like new and in excellent condition – a must have for every radio amateur with emergency operations in mind.
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.
