|Remote Control Heads|
This equipment is two Remote Controllers for all the radio communications equipment on board an aircraft.
The upper unit (a Gables G-3837-02) controls the VHF equipment used for short range communications (to local airport etc.) and the lower unit (a Gables G-3751) controls the HF equipment used for long distance communications (for company traffic to home base etc.)
The complete unit controls a total of 4 transmitters and receivers (2 on VHF and 2 on HF) each with its own individual Frequency selection plus, on HF, Mode (AM or SSB) and RF Gain.
It should also be noted that due to “standardisation” between manufacturers, it is not necessary to have the same make of Control Unit as Receiver or Transmitter; for example the Control Unit could be manufactured by Gables Engineering and the Receiver and Transmitter could be manufactured by STC or Collins etc.
These units are from a British Airways Concorde but are typical of equipment fitted to a wide range of aircraft during the 1970’s and 1980’s including the Vickers Viscount, Vickers VC10 and BAC 1-11.
