Transmitter/receiver TR 9-F
In working condition.
This is the pre war wellknown “SPITFIRE” sender receiver, type TR 9 F. Although the type 9 F is not used in it, but in the bigger aircrafts like Lancaster etc. for communication between the airfieldtower and the aircraft in close distance.
It is fully working in the 40 meter band with a crystal on 7078 Khz, amplitude modulated, by means of a intercommunication amplifier, type A 1368. For using this amplifier, I had to make the connectors and the plugboard myself.
Normally a A 1134 is used. By lack of that type, to let it work, I used the A 1368 intercommunication amplifier.
Question: can anyone tell me about the precise usage of the A 1368 in the RAF?,
Pse some info in the COMMENT at the end of the page.
