Contemporary 1966 film of the tracking equipment

Recording Equipment

Tape recording the sound of satellite transmissions was often the means of creating a permanent record of the signal content. In 1967/8 this was complemented by acquisition of the GNT Undulator, a simple but very effective chart recorder that used ticker tape as its recording medium.

Item Purpose Note Currently Residing
Tape Recorder Recording of signals Geoff's personal equipment used at home and at the school

At least three of these (in addition to the Ferrograph) - different examples can be seen on the 'Wonderstuff' album cover and in Sven Grahn's 1979 photographs

AEI 8-channel Polygraph Analysing/decoding telemetry from Parus and Tsikada satellites Acquired by Derek Slater from English Electric - the original source may have been a hospital
