ATR-11 Transmitter[Receiver There were a number of sets that were unique to the RCAF during World War II and, except for the AR-2/AR-6 receivers and companion AT-1/AT-7 transmitters, all the others have poor documentation availability.
The intended use for the ATR-11 was for aircraft-to-aircraft and aircraft-to-ground communication. By having autotune capability, it eliminated the need for a dedicated radio operator. The radio covered the frequency range of 2.5 - 6.0 MHz. Accessories included a control box for the pilot's use and of course a separate dynamotor power supply that is surprisingly small by military radio standards. Another accessory was a low frequency tuner that fed into the ATR-11. This enabled reception of radio range stations and low frequency navigation beacons in the 200 - 400 KHz range as well as switch selection of 278 KHz, a common airfield communication frequency for many years.
Can anyone verify if Canadin Marconi also produced the ATR-11 besides RCA, Contact: jerry.proc@sympatico.ca
