Fernbedienungsgerät

Remote Control System

for use with Torn. Fu. d2, Torn. Fu. b1, c, f, k

Vb.K (Fbg.bf) and Fernbesprechzusatz f. (remote control for Tornisterfunkgeräte)
 

These devices comprise the remote control communication system designed to be used with the following transceivers:

  • Torn.Fu.b1
  • Torn.Fu.c
  • Torn.Fu.f
  • TFuG.k

Since these transceivers were predominantly used for artillery observation, sometimes the observer had to be located where the radio communication was not good. This remote speaking system was designed to locate the transceiver in a good radio position, while the observer was up to 100 meters away - with good visibility of enemy activity.

Interesting acceptance stamp on the inside of the 1937 version, with a Waffenamt stamp on the left.

 

 

Inside the 1942 Fernbesprechzusatz (bf). On the right is the mode communication switch and on the left is the dynamo for ringing a bell on the spool (Trommel). The most noticeable difference between the 1937 and 1942 models is the type of capacitor in the middle of the unit.

Front panel of the spool. Almost identical to the 1943 version less the "Feind hört mit" sign and lighter green color characteristic of the pre-war period.
