[ARC5] Talking to Airplanes From the Ground (more on AN/TRC-2)

[Hubert Miller]

Yes, when I refer to the TRC-2 I usually mean just the RT-12.
The PP-39 I think, was the "vertical, stand-up" model, while the PP-39-A, if I remember right,
has a horizontal format of the rectangular box format. I guessed this was maybe because it
was more likely to avoid being knocked over and having the battery go horizontal. 
I think the TRC-2 I bought from Pacific Surplus in Seattle cost me a whole $15. Altho I knew 
not much about electronics then, I figured out the schematic conveniently provided inside
the case and powered the receiver, and used it to listen to the Seattle Marine on 2522 kHz,
KOW2.

AN/TRC-2 actually had two radios.  One was BC-1306, which covered 3.8 to 6.5 MC.  The other was RT-12/TRC-2, which covered 2.0-3.4 MC.  Why the gap in coverage, I have no idea.  In any case, it was filled in when the AN/TRC-2 was effectively replaced by one of the variants of AN/GRC-9.  But although development of the GRC-9 probably started before VJ Day, the GRC-9 wasn't in production until 1946.

Anyway, I would guess that the radio that you had would have been the RT-12.

And I think that the power supplies that you are referring to are
PP-39/TRC-2 and PP-39A/TRC-2.  Which are vibrator supplies that run the receiver in either radio.
