Aerial Artificial type 1A


The Aerial Artificial type 1A is used in the RAF for aligning the output transmitter stage of the pre-war T 1083 for test purposes. This type 1A is a prewar type.

A schematic diagram is shown is picture 1. Note the different conections for the different frequence ranges.

It can also be used very easily for aligning the TR 1196 or TR 9.

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.

four channels.

 Working condition.

This is a  transmitter-receiver used in airplanes like Lancaster etc. It is a four channel unit. For the receiver, as well as the transmitter, four crystals are used.

It is remote controlled by a switch box. On the picture a replica controll box is used. But the whole unit is working. Supply voltage is 12 volts, which indicates it is an earlier one.
