• Notes

• The set was produced by Radio Corporation, closely resembling the British No.22, but using readily available Australian components.

  The set was intended as a primary vehicle station with facilities for quick removal from the vehicle to be used as a ground station. Transport by man-pack was by three man-carried loads.

  Immersion covers were provided with the man-carried station for fully water-proofing the radio for use in beach landings and river crossings.

  Covered 2 to 8 MHz in two bands.

  Production commenced in March 1943.

  Set consists of the transceiver itself and a separate vibrator power supply unit.
  The vibrator power supply operates from a 12 V accumulator developing 300 V at 80 mA for the transmitter and 150 V, dropped by a series resistor for the receiver.
