  • Anotaciones
  • The Fullerphone was basically a DC line Morse telegraph. The main feature of the Fullerphone was that the transmissions were practically immune from overhearing by radio, which made the system at the time when it was devised very suitable for use in forward areas. In addition, the Fullerphone was very sensitive and a line current of only 0.5 microampere sufficient for readable signals. In practice, however, 2 microamperes were required for comfortable readings and it could be worked over normal Army field lines 15-20 miles long.

    From 1935 the "Fullerphone Experimental" was developed. The result was the Fullerphone Mk.IV.

    Fullerphone Mk.IV* was an update of Mk.IV with radio filtering to reduce interference of radio interception.
