Description

Radio Set SCR-578-A or SCR-578-B is a simple rugged emergency transmitting system designed for operation from a rubber life raft. No receiving equipment is incorporated. The set provides automatic code transmission of predetermined signals so that any operator, no matter how untrained, can send distress signals which, when received by rescue parties, will permit bearings to be taken. The set operates on the international distress frequency of 500kHz with a 1000 Cycle tone modulation.
