ABSTRACT:
Disclosed herein is a signal priority device responsive to the audio output signal of a citizen band (C.B.) transceiver for switching the response of a common speaker system from the audio output signal of a radio receiver to the audio output signal of the C.B. transceiver. The disclosed signal priority device is connected between the existing audio output jacks of the radio receiver and the C.B. transceiver and a common speaker system, and automatically integrates the operation of the two separate devices. The signal priority device is transparent in the system when either the radio receiver or C.B. transceiver is turned off.
