Abstract

PURPOSE:To know the presence of communication from antoher car while a radio receiver and other sources are turned on, by leading out output signals from the radio receiver and other sources through a mixing circuit. CONSTITUTION:Audio signals appearing at the IF amplifying and detecting circuit 102 of an FM reception part and an AM reception part 103 are both supplied to a preamplifier 105, whose output is supplied to one input of a mixing circuit 107 through a muting circuit 106. A playback signal from a tape deck 11 is supplied to the other input of the mixing circuit 107. A control part 104 selects an AM mode and a reception frequency is equalized to a transmission frequency from another car. In this state, while reproduction is carried on by the tape deck 11, the arrival of a communication signal from another car allows the signal to enter the mixing circuit 107 from the reception part, and thus a sound mixed with a playback sound is listened to, thereby knowing the communication from another car.
