I put all the nomenclatures, frequency ranges, IF frequencies, calibration crystal frequencies, etc. of these sets fram RAT to Type 11, ATA to AN/ARC-5 in a pdf file I posted here 13 months ago:

AFAIK, all known non-VHF units are listed.

Yes...the T-14/TRC-1 70-100 MHz FM terminal set.

FWIW, the associated receiver is R-19/TRC-1.

The first AN/ARC-5 receiver took the next JAN component number, R-20/ARC-5.

Before the common well-known R-23/ARC-5, there were three communications receivers that were essentially nothing more than the ARA or RAV receiver with JAN name plates:

R-20    1.5-3.0    Equiv. to ARA/RAV CBY-46104.  Developed to R-25.
R-21    3.0-6.0    Equiv. to ARA/RAV CBY-46105.  Developed to R-26.
R-22    6.0-9.1    Equiv. to ARA/RAV CBY-46106.  Developed to R-27.

These are very rare to non-existent today, like the RAV CBY-46107 9.0-13.5 unit that is the Holy Grill of command set lore.  Gordon White may have the only remnants of one anywhere.

Afterwards, we get to the common improved receivers R-23 through R-27.

All are tabulated in the first link above.

But...I digress.

Aren't you sorry you asked? :-)
