[Milsurplus] Vintage Mil Aircraft Radio Components

[Bruce Gentry]

As a side but real part of history, by 1970 someone in the Air Force 
could obtain an ARC-58 for a case of Chevis Regal if they were patient 
and knew the right people. The manuals were unclassified and easy to 
get, especially if you would accept a dirty or tattered one from the 
shop.  The rig's reliability was hotly debated, and bench warmers and 
others that slipped through the cracks were definately to be had. I was 
offered one, but the 400 cycle power needed was a hinderance at the time 
and I declined. I now have one, as well as a URC-32. They work well, but 
I doubt they would meet the standards required at the time. Were the 
failures cited total ones that rendered the rig unusable, or failure to 
meet the specs perfectly and dot every "I" and cross every "T"?  The 
Strategic Air Command was extremely finicky, with good reason. There 
were so many 1950s vintage rigs that had to be carressed, cursed, and 
blessed to squeak by the standards in 1970, but worked perfectly in the 
practical sense day in and day out for months with very little attention.
