Gleichstromnetz-Gerät
Das Gleichstromnetz erfordert, dass der Stecker richtig gepolt sein muss, damit der Apparat spielt und keine Spannung auf dem Chasses gegen Erde auftritt!

Notes
The ARC-51 is a UHF AM transmitter/receiver intended for air to ground communication, covering from 225 to 399.9 MHz in 3500 channels, with 16W RF output power. The mechanic and electronic designs are extremely advanced. The external cabinet is sealed and pressurized. Tiny heat exchangers in the basement transfer heat from the internal air flow to an external one. A modular design is used, with the central frame which supports the modules and provides electrical connections and air flow to them. The equipment is almost entirely solid state, with the exception of UHF stages: three tubes are used in the transmitter, three in the receiver and two more in the spectrum generator. The tuning is motor driven, with a driving module and a complex system of gears to distribute motion to radio frequency modules. A standing wave indicator, the ID-1003/AR, is mounted outside the cabinet.
