[ARC5] [MRCG] SCR-515/ABA IFF Code Wheels

[J Mcvey]

Got a picture or a URL that points to one?I think I have some kind of old punch tape reader somewhere. If it might be what you need I'll look for it. Haven't seen it for 30 years or so because I think it may be at my parents house. I do vaguely remember what it looked like, though.

 Code Wheels
Speaking of Hen's Teeth, the Flea market of the California Historical Radio Society bestowed upon me a: Radiac Meter IM=108 PD (Army, circa 1957) which turns out to be a 3 MHz crystal controlled transmitter with an 807 output tube ~~ and it is keyed by a code wheel.  How it works and what is does is a long story I'm happy to tell anyone who is interested (KV6LEE at gmail.com).  But we're looking for code wheels, maybe even the same type. (Did they have to re-invent the wheel?  Probably.) It has great potential as beacon transmitter for at least 80 meters for our station W6CF.
Some have suggested we look to 3-D printing to make one or more up.  This is a viable alternative.  The nearest MakerSpace can help.

I've been contacted by a 96 year old collector named Harold Meltzer who is looking for a single code wheel for the SCR-515/ABA IFF set to complete a display he's working on. Interestingly, he was actually involved in the development at GE-Bridgeport in 1941!

I no longer have any SCR-515 gear in my collection.

If anybody has one of these hen's-teeth for Harold, I can pass a message along to him or you can email him directly:
