。 A high frequency amplification means connected to an antenna provided on the vehicle and including an FM high frequency amplifier and an AM high frequency amplifier, and a high frequency amplification means provided on the vehicle for supplying power to the high frequency amplification means and supplying a received signal from the high frequency amplification means. In an on-vehicle receiving device comprising a receiver, when the power is turned on, the receiver
The high frequency amplifying means has a circuit for generating a control signal for selecting one of the FM and AM bands, and the high frequency amplifying means generates a control signal for selecting one of the FM and AM bands based on the control signal received when the power of the receiver is turned on. It has a power supply switching circuit that supplies power from the receiver to only either the high frequency amplifier or the AM high frequency amplifier, and the high frequency amplification means and the receiver are connected by one cable. An on-vehicle receiving device characterized in that the power source, the received signal, and the control signal are frequency-superimposed and transmitted.
