  • Bemerkung

  • This (CW) set comprised a transmitter and a heterodyne receiver in separate boxes. It came into service in 1917 and was used for forward area telegraphy.

    The transmitter was rated at 30-watts and had a range of 3.7km. It utilised two valves which were either the type B or AT25.

    The receiver had two R valves. The first of these was used in a heterodyne circuit and the second was as an audio frequency amplifier for the Morse signal.

    The complete set also included a heterodyne wavemeter, Selector Unit, and Rectifier Unit.

    Total production was a little under 3000 for both the transmitter and the receiver and approximately 400 of the Selector Units.

    Frequency Band: 450-1450 metres.
