[Milsurplus] SC-901X questions

[Ray Fantini]

Lots of stuff sneaks thru as special requirements or programs, look at the RF-301 that’s not exactly Mill Spec but it became the AN/URC-53 because there was a need. Other radios never got AN designations despite wide use like the VHF-FM RF-403 transceivers.
Would love to speculate that one of the Navy’s most loved family of radios that includes the R-1051 and URT-23 were the love child of the SC-901 and General Dynamics and sprung forth the USAF requirements for a synthesized SSB radio for missile silos.

Have thought about installing a RF Technology RF-403 in the mutt, being it would be a period correct radio that can be installed for two meters. Been using a Motorola URC-110 but that’s just a little too new to go with the rest of the equipment and think I know where I can get a 403 for the cost of shipping, then have to deal with the whole rock issue.

During the Vietnam War, the USAF developed aircraft jammers such as the QRC-160. QRC stands for Quick Reaction Capability and relates to development and deployment of weapon systems ahead of the standard AN/xxx process.  The QRC-160 was developed by the USAF and deployed with the Navy as well.  It later became the ALQ-71.

Hue has the SC transceiver so the military “equivalent” is the RT-618/UR info found in the URC-35 manual.

Speaking of which, if this thing was designed for the USAF, why the goofy commercial model number and not an AN/xxx compliant designation????

Has anyone got a dated component or inspection stamp to help figure out the chicken-egg history? I bet there is a good story here but I don’t know what it is.

Yes sometimes the Navy will pay R&D costs on a project that has spinoffs or versions for other services. USAF used a number of Navy-developed equipments but I haven’t come across USAF to USN transfers. Army-Navy sharing was not common (R-390A being a notable exception) And of course USMC used lots of Army gear.

I sure wish someone had written a history of all this procurement.

Nick, puzzled as usual.
