HARVARD RADIO FIT
It appears that a large number of the RCAF Harvard fleet surplussed out in the 1960's had been equipped with the ATR-11 radio at some point in their service lives. One known example, circa 1942, was made by RCA.
The radio is crystal controlled. Four dials are for the Receiver, Transmitter, Aerial Coupling and Aerial Tuning. Two separate sets of frequencies can be set and locked in. Range is 2.5 to 6.0 MHz. It has its own remote 24V Dynamotor and a Control Box unit that would likely be installed in the pilot's position. When you select various frequencies on the control box, you can hear servo motors humming and clicking away in the transceiver.
Any manuals out there for the ATR11?
