Astro...Don Stoner's legacy

How many of these rare transceivers have you seen?

Posted By: Robert Nickels (ranickels)

A recent post on the Cubic-Astro mail reflector noted the similarities between the rare CIR Astro 200 and the much more common Cubic Astro 150 transceivers.   And therein lies an  interesting story...

I have done a little research on the CIR Astro 200, and the commenter was right - it is the progenitor of the Astro line we are much more familiar with as a result of Swan (already owned by Cubic) taking over CIR in 1978.   But the Astro 200 was based on a design by SSB pioneer Don Stoner, W6TNS.   Stoner had been in the mil/commercial SSB business by way of Stoner Communications of Cucamonga CA in the 1960s, and more recently was the "S" in SGC, which he formed with Pierre Goral in 1971 and which still exists today.    By 1977 Stoner, now in Mercer Island WA, evidently chose to pursue a different business model.  Instead of bearing the burden of capitalizing another manufacturing company he shopped the design of a compact solid state HF transceiver around to various ham manufacturers under some sort of license or royalty arrangement.   His sales tool was a working 80-10 meter 100 watt synthesized SSB (only) transceiver bearing the name "Stoner PRO 80-10".    It bears the the same similarities to the Astro 150 that were noticed in the CIR Astro 200.

KLM was a big "force" in antennas and linear amplifiers at the time and launched the production of what essentially the Stoner PRO 80-10 under the name KLM FORCE 5 (there's a photo in Joe Veras' book).    According to one of the founders of KLM the radio did not pass FCC testing and the project was dropped after a few dozen radios were produced.   The other company who took interest in Stoner's design was a start-up called CIR Industries of El Cajon CA.   In essence, CIR looked at Stoners design and found it lacking several important features to make it acceptable to hams, and did a it of redesign to add the CW mode and narrow filter, a fine tuning and RIT feature, noise blanker, and even a squelch.   It was virtually the same size as the PRO 80-10 but with different cosmetics including a metal cabinet rather than Stoners trademark walnut side pieces (which also appeared on his CB designs).   But the most obvious similarity - the two toggle switch up/down controls (mirrored on the hand mic) are the same as on the Stoner design and the would-be KLM    That's because the synthesizer in all three - and in the later Cubic Astro models - is the Stoner design.

I've always envied Don Stoner for making a career out of writing about and building radio equipment, mainly SSB gear, but it's unlikely his last sideband transceiver design made him much money, although at least parts of it certainly had a decent run in the Cubic Astro transceivers.  By the way, Don Stoner is also the "father of OSCAR" having outlined the idea of putting amateur radio satellites in orbit in a 1961 article in QST.   I've always intended to write a story about him and his companies, and would welcome any input.



    In his book "In Touch with Leo", the success and growing backlog of CB-100 orders is what drove Leo to his banker, Lou Ross, who asked him why he didn't anticipate the number of orders and required capital.  Leo responded "Lou, never on God's green earth could I have believed such an influx of orders!".    More funding was needed than the bank ...  READ MORE

Spectral Purity using Epson Programmable Oscillators

Do harmonics matter if there's no way for them to be heard?
Category: Crystal Replacement
 In the 5 or so years I've been using the Epson oscillators I've looked at the spectral output many times.   Without a doubt the harmonic output from the Epson oscillator is high as would be expected  from a square wave device.   The question to me has always been "does it matter"?PLL controlled digital oscillators have long been used as LOs in recei...  READ MORE

 When I was a kid, my dad gave me a thin hardcover book called "Boys Fun Book - Things to Make and Do".   It was printed during WWII on very thin paper as a wartime conservation measure, but was chock-full of interesting projects, ranging from hobbies and magic tricks to sports, puzzles, camping...and the chapter I was drawn to:  "Unusual Radios You Can Build You...  READ MORE

   As anyone who likes building radios knows, it's getting harder and harder to buy RF components.   One of the last casualties was the 3-section pi-wound RF chokes made by Hammond, a company that has done more than most to support the vintage radio and audio hobbies.    The Toko variable inductors long favored by QRP enthuisiasts have become all but unavailable, and vari...  READ MORE

The Case of the Phantom Voltage

“When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.”
Category: Technical
A Heathkit HW-12 gave me a troubleshooting challenge the likes of which I've not seen before - or even heard of!A few days ago the transmitter wouldn't produce output, and in checking voltages and I measured -75 volts on the ALC line which should be -20.   But it corrected itself and I figured it must have been a solder splash or something that cleared by itself.  That theor...  READ MORE

The Solvay Conference, 1927

The Smartest Photograph Ever Take
Category: Historic
The Solvay Conference, founded by the Belgian industrialist Ernest Solvay in 1912, was considered a turning point in the world of physics. Located in Brussels, the conferences were devoted to outstanding preeminent open problems in both physics and chemistry. The most famous conference was the October 1927 Fifth Solvay International Conference on Electrons and Photons, where the world’s most...  READ MORE

   Put yourself in 1963...A stamp was a nickel, bread was 22 cents a loaf, and you could buy 3 gallons of gas for a buck.   The average wage in the US was $84 a week.  If you were a ham, you might have been able to build and trade your way up to a really nice AM/CW station - maybe a Valiant or DX-100 transmitter with an NC-300 or HQ-170 receiver - a huge improvement over the S-38 you s...  READ MORE

The DX-60 Family

what hath Benton Harbor wrought?
Category: Vintage Ham Radio
When an engineer at Heathkit in 1962 turned his attention to designing a replacement for the somewhat flawed DX-40 novice transmitter, little would he have expected the DX-60 to remain in the Heathkit catalog for 14 years.    From the new solid-state power supply to the streamlined apeperance and dependable performace, the new transmitter was instantly popular with novices who had t...  READ MORE
