The components of the Telefunken Aircraft Station Stat 1005a F (with the parts Transmitter As 82, Receiver Ae 83 and antenna tuner Al 84), which was used in planes of the Swiss Air Force as FG IV, have also been used as (improvised) ground station.

The receiver Telefunken E 406 F is a five valve (all NF4) superhet covering 3000 - 6000 kHz in the shortwave band.

The transmitter Telefunken S 347 F covers also 3000 - 6000 kHz in the shortwave range. In the modulator three (or four?) valves NF4 (later RV12P4000) are used, one of them as AF generator, two more as modulation amplifiers. One RS287 (RL12P35) is used in the driver stage and two more RS287 in the RF final stage. The output power is 60W in CW telegraphy and 25W in telephony.
On an image of the Z-Staton 38, also the wave meter Telefunken Spez 831 F used to calibrate the aircraft sets can be rocognized in the right front corner.

I would be very thankful for further information and images of this station in field use.
