Aircraft radio communication system FuG 10
The standard aircraft radio communication system FuG10 for all larger Luftwaffe aircraft is shown here as a
complete, fully-interconnected and working demonstration system
FuG 10
The FuG 10
featured:
MF and HF radiotelegraphy Flight crew intercommunication via Air-to-air & air-to-ground HF radiotelephony (with modulator unit)
a built-in interphone
In 1936-37, the firm of Lorenz AG* developed the aircraft radio system FuG 10 for the Luftwaffe.
Starting from 1939, it became the preferred equipment for larger aircraft with several crew members (e.g. Ju 88, He 111, DO 217, ME 110).
The FuG 10 set was officially standardised. By the end of WW2, Lorenz AG and numerous licensees had built nearly 300,000 sets.
The photo (top right) and drawing (right) show the radio operator's position with all controls and equipment units.

E = Receiver
S = Transmitter
L = MF (long-wave)
K = HF (short-wave)
Thus,
EL = MF receiver
Among these are:
Circuit breakers (power on/off, overload protection),
HF and MF transmitters and receivers (EL - SL - EK - SK) - each with four preset frequencies,
Antenna remote-control box - radio set selection, antenna tuning (fixed or trailing-wire antenna), pay-out and and rewind of the electrically-powered trailing-wire antenna (length 75 m),
Radio operator switchbox - central control unit for the crew headset/microphones plugged in to the system,
Radiotelephony unit for mode selection (telegraphy/telephony),
Morse key for radiotelegraphy, also used as press-to-talk key for radiotelephony.

The interphone amplifier is in the tube unit RG (left). Note nameplate.
When operating or testing the radio equipment on the ground, an external battery must be connected to the "External Connection to Aircraft Electrical System" socket (right).
