A couple of weeks ago, I acquired a Thomson ER-104-A transceiver, which is the French version of the 618T-2.
The schematics and the internal structure are quite different from Collins, but were interchangeable with the 618T-2
and fits in its mounting.

As far as know, the French army decided to develop their own equipment when they left NATO in 1966.
This  transceiver was used in several aircraft, among the Breguet Atlantique.

For your interest see attached document and photo's. You're free to publish it. The document is in German language.
So it was apparently also used in Germany as "Funkanlage TR-AP-33-A".

 

Practically nothing can be found on the internet about this  transceiver , likely because in France all documents
were destroyed after equipment was taken out of service.

 

Next step is to get the set in working condition. Luckily I have the control box and 2 important connectors already.
