[MRCA] RCA AVR-100A

[Mike Morrow]

Best I've been able to determine, the AVR-100 appeared just after WWII.

The battery voltages required are very common for battery powered range receivers of that era, such as the Setchell-Carlson Model 591 (1943).  

There was a matching (but larger) dry-cell powered transmitter (about 2 watts out on 3105 kc) called the AVT-110.

The AVR-100 could also be powered from the AVA-126 vibrator supply when that supply was being used with the AVT-111 transmitter, which was the same size and power (12 watts) as the common AVT-112 and the AVT-110 mentioned above.  It had preset crystal control on 3105 and 6210 kc.  A dry cell was still required in this installation for C- voltage.

As a package, it's not quite as nice as the competing GE radio of that era, the AS-1B.

Fellow old gear guys,
 Does anyone have a date for this?
Something just acquired is real cute! It is the AVR-100A Beacon and Broadcast band aircraft receiver by RCA. It is small, looks new, and, if it works, I may finally have something to connect to my loop antenna. No date on the manual. Get this, it takes 7.5v C-, 1.5v A+, and 67.5v B+. It is about the size of four packages of cigarettes, packs not cartons.
