Austria spy radio set
- this page is a stub
BE-20 was a three-piece short-wave
spy radio set,
built around 1948 by Dr. Hermann Berger
in Innsbruck (Tirol, Austria). The device was intended for several customers,
including the Austrian Army, the armies of the occupying forces 1
and the state security services.
It was also used for a secret
Austrian Stay-Behind network
that would be activated
in case of problems with the USSR.

The BE-20/1 is the protype of the radio set, that was presented to the French
Army around 1948. After a few modifications, the set was approved and
went into production as the BE-20/2 (Poste Cunzi) for the French Army,
and BE-20/3 for all other customers, such as the
B-Gendarmerie and the
secret stay-behind organisation ÖWSGV.
Although the circuit diagrams of the BE-20/1 prototype have been retrieved
(see below), there are no surviving samples of the device that we are
aware of. The circuits are very similar to the actually released devices
BE-20/2
and BE-20/3.

Note however that the pinouts of the various connectors and sockets on
the body of the device are completely different from the ones on the
released devices. The circuit diagrams below are provided for
reference only. Please use the information with care when restoring
a device.

not fully match the circuit of the production units (BE-20/2). Ignore the
connections of the 6-pin LIST connectors as they are wrong.
