Thanks, Todd. I remember seeing you and your daughter at Frostfest. Nice photo! Unfortunately, Frostfest hasn't been held since COVID.

I have worked into Minnesota on AM on 40m, and on 75m when the band is quiet, so I'm sure we'll run into each other on AM.

Don't remember the conversation nor does the product pictures ring any bells. Ed never provided me with any paper work on this Comet.


The Climaster 62T10  covered 2, 6, 10, and 11 meters.

Then there was the Clegg 250 and the  209 Crystalplexer.

AND in Electric Radio Number 407, Jan./Feb. 2025, an article with pictures written by Bob Allison, WB1GCM, with lots more detail about the Clegg 250 and 209 Crystalplexer. This is running equipment at the W1VCM museum station in Windsor, CT.

Squires Sanders closed its doors in 1970. It's not clear if it was bankruptcy or other reasons.
They were never located in NH.
After they closed, Bill Squires reemerged as president of Computone Systems, Inc. at the same building location. A friend who worked at Squires Sanders indicated that a number of the original Squires Sanders workers stayed on with the new company. Even after Squires untimely death, Computone Systems continued on making some type of computer terminals. Even under the Squires Sanders tab, they made CCTV cameras, CRT Monitors, and associated accessories.

I think this mention is long over due. 

The mods, John, Todd, Pete, Steve, etc. have a thankless job keeping the various AMfone forums in line and operating smoothly. They have been keeping it running smoothly since the AMfone kickoff. 

Thanks for keeping it together and not letting it turn into typical social media mayhem that we see today. 

On behalf of the membership and myself, a job well done, thanks guys. Hope it continues for the many years ahead.

Not trying to be ignorant or offensive,but there are a couple procedures involved in superheterodyne troubleshooting and wanted to review them with you.
Step one, confirm the power supply is working correctly. If the output of the DC power supply is low or has excessive ripple (AC voltage) it can show up not only as noise but as a number of other issues. Always confirm its DC and percent of AC is correct. Anything below a third of a volt peak to peak is usually good.
Step two,try to determine what works and what don't. every system can be broken down into smaller sub systems. In the superheterodyne you have a RF input stage, mixer oscillator, fixed intermediate frequency (IF) stage, detector and audio stage. There are also some other things you can throw in there like AVC, product detectors and filters but let?s try to keep it simple first.
Already addressed the power supply. Let?s work backwards! On that radio if you select the mode switch to the phono position do you still have hum? If you inject audio at the phono connector at a very low level do you have lots of clean output? That radio has a high power push pull amplifier and generates tons of gain when working right.
I tend to treat the detector and the IF section as one block so let?s look at that next. Try injecting 455 KHz at a very low level on the grid of the first IF amplifier(V6) that will tell you the status of the IF chain and detector.
And last would be injecting a RF signal at the antenna input to confirm the RF, mixer and oscillator are working correctly.
You're going to see that you will need a signal generator for generating RF, IF and audio signals with a variable output. You already have the scope for looking at AC signals and a meter for DC but if you are going to get anywhere working on receivers you going to need a good signal generator.
At first it may all be overwhelming trying to separate a large complex system like the sixty but with time you will learn how the stages work and that many superheterodynes share the same structure.
Sometimes its best once you get your signal generator to take something that already works first and learn by trying injecting signals at different points in it and seeing what type of levels to use and what results to expect. After you master a basic tube type AM radio you can then progress to the more advanced sets.

Listening now, Bud. The band is somewhat crappy overall, though I am hearing MI, WI, even IN pretty well. Gerry is barely readable. I have a project receiver on the bench right now, so the Injuns are offline. I tend to shy away from groups when running the peanut whistle station. Don't wanna end up being in that group of 'The ones who are weakest talk the longest'.

That wouldn't surprise me at all, Steve. They appear to have had government contracts at different times. Would be interested in hearing more. It does seem like they were one of the more esoteric electronics firms of the day.

Pete - photos attached of the Comet that sold on ebay years ago. Mine is  still boxed up, similar but missing the relay and front switch. I was sure you gave me the callsign of a W2 in NJ who had the only completed example that they used for testing. Maybe a former employee? W2NLJ? NDL? It was probably 20 years ago or more.

I concur that neither Interceptor showed SS on the dial, have both versions. Ed also mentioned a Climaster Zeus which had 10m on it as well, early version perhaps?

The history and progress of these products has always fascinated me. Those of us not around or yet active at the time are very fortunate to still be able to enjoying using the gear decades later.

Hi Todd!

Just a note; give a listen on 7295 around noon time and see ifn it'll be feasible to join the Noontime Forum. Gerry KC8ZUL is net control most days. Steve K0SF has checked in from time to time.

Didn't Squires-Sanders have a big operation in Nashua, NH?  IIRC, BAE bought them.

Don't remember a Clegg Comet nor can I even picture it. It was probably designed after Ed left Squires Sanders and opened some manufacturing in Hanover, NJ. That's where the Clegg 22'er MK II was manufactured and supposedly where the Clegg 22'er MK III   https://www.rigpix.com/clegg/22ermkiii.htm
was going to be manufactured roughly in 1971/72 but he sold the business to a company in PA and moved out there.
