BC-611-F


This photo is generic and not my unit. My unit is in excellent condition.
Nameplate:
Signal Corps U.S. Army Radio Receiver and Transmitter BC-611-F
Ser. No. 32458    10531-PHILA-45-01
Galvin Mfg. Corporation
Chicago        Illinois

Radio is labeled BEFORE OPERATING READ TM-11-235

I have one radio. Since I don't have a 103 volt battery, I don't know if it works or not. It is very clean inside. May 21 1945 is marked inside. It's on 4840 KC and has the following tubes: 3S4, 1R5, 1T4, 1S5, 3S4. Our museum has four of them. So far I haven't had time to get any of them working. All the IF transformers have open windings.

It uses a BA-37 battery or with an adapter it can use a BA-30 for the 1.5 volt filaments.. HV is supposed to be 103.5 volts using a BA-38 battery. Somebody in Italy makes a nice little solid state module to use a "D" cell to generate the high voltage. Brooke has some good power supply info.

I remember working on these when I worked for the Norfolk Naval Shipyard around 1966 or so.
