AN/ARC 5 ARC5 LF MF & HF
Aircraft Radio Transmitter and Receiver

Model AN/ARC-5 Aircraft Radio Equipment is a complete multi-channel radio transmitting and receiving set providing communication and navigation facilities for aircraft.

The LF-MF-HF components are designed to transmit and receive voice, tone-modulated, and continuous wave (cw) signals.

GENERAL PRINCIPLES OF OPERATION.
Primary power (14 or 28 volts dc) is furnished by the aircraft’s electrical system.

This power is distributed through a junction box or mounting rack, and is controlled by the off-on switches located on the control units.

These switches, designated variously as ON-OFF, SENSITIVITY, or VOLUME, are either toggle- or rotary-type switches.

Individual dynamotors furnish high voltage to the radio receiver circuits.

High voltage for the transmitter circuits is supplied by a dynamotor mounted on the modulator unit.

For voice or cw operation, the radio receivers are tuned either locally or remotely through mechanical linkage connected to the control.

Lock-tuned operation of the radio receivers is available for voice reception only.

The transmitters are pre-tuned with their frequency controlled by a master oscillator.

The type of emission and the transmitter required are selected by individual switches mounted on the transmitter control unit.

No antennas are supplied with the AN/ARC-5 but the equipment is designed for use with a single-wire antenna of the trailing or fixed type, a vertical mast antenna, or a loop antenna.
