Aircraft type transmitter used by the Royal Flying Corps and Australian Flying Corps during World War I. These transmitters were installed in two-seat reconnaissance aircraft such as the RE.8 used to spot German artillery and troop concentrations and call in artillery fire by morse message. A long 120 foot wire aerial on a reel had to be wound out by the observer to enable transmissions to be sent on the 100-260 metre wavelength. Power was provided by a 6-volt wind powered accumulator providing an output of 30-40 watts.
