[Milsurplus] FWIW: List of all RU-type receivers and GF-type transmitters by USN type number

[Mike Morrow]

I have a work-in-progress that presents detailed information on all 31 USAAC radio sets and all 28 USN radio sets that use receivers (BC-A*-183, RU-* types) based on the A.R.C. Model D.  Here is an excerpt that Nick's and Mike's USN type number documented has allowed me to refine.

B - Beacon Band Only
C - Command
G - General Non-Aircraft
L - Liaison

CBA - Aircraft Radio Corporation (early)
CBY - Aircraft Radio Corporation
CW  - Western Electric Company

Radio set GF consist of transmitter GF and receiver GF.
Radio set GF/RU-2 consists of transmitter GF and receiver RU-2.

Receivers GF and RU through RU-3A can be configured for either command or liaison service.

I am interested in getting more info about receivers RU, RU-1, and RU-3A (schematics especially).

I hope to finish my work related to these USN sets (and the USAAC relatives) in a couple of months.  It will be a pdf approximately 75 pages long that will be free upon request to anyone with an interest in these old systems.
