[Milsurplus] SC-901X questions

[Ray Fantini]

Cannot imagine the Navy had anything to do with the development of the radios that were used in USAF missile sites. It’s a General Dynamics thing and perhaps predates the R-1051/T-827 family. As far as shape, power and design the radio was only part of a larger system and not intended for standalone use. This would only occur after it was surplus.
Perhaps the SC in SC-901 refers to Stromberg Carlson that was acquired by General Dynamics in the mid-fifties. With that design put forward and then adapted by General Dynamics we then got the R-1051/T827? But this is pure speculation on my part but I think that is more plausible then something involving the Navy.
Would assume someone knows the dates and family tree.

The SC90x modules are similar to the the R-1051 series but non interchangeable. The SC modules are older generation with many similarities but not the same.

I have an original manual for the SC-908. It is a USAF T.O. dated 1 March 1963.

There was a matching 1kw SC-9?? amp using a PL-172. One shows up on eBay every now and then.

I suspect this was all a USN funded development effort. Air Force use was just incidental. The low power exciter design allowed flexibility as it did for TMC.

And commonality of modules for transceiver, receiver, and transmitter was a big plus. Navy versions were RT-618, R-1051, and T-827. Amps for 100w (AM-3007) and 1kw (AM-3924) output were used.

OT- Duck and cover was to protect kids from flying glass and debris. No use at ground zero but there would be huge areas getting shock wave damage. People nowadays laugh at CD, SAGE, etc. but remember this was just after a world war with 100 million dead and suddenly a single aircraft could destroy a city. The govt was rightfully extremely worried.
YMMV
