Made by Canadian Marconi in 1944, this unit was capable of transmitting on low wave (375 to 580 kHz) or short wave (1700 to 4200 kHz) depending on the model type. On receive, it could tune from 300 to 4200 kHz continuously. Power input was 15 watts on CW, less on MCW and even less on phone. Input power to the FR12 was 12 volts DC at 6 amps on receive and 13 amps on transmit. The RCN used this unit for administrative communications among ships in company. The FR12 was considered to be lightweight by 1944 standards, but think of how much capability one could have with 69 pounds of today's equipment!
