換わるようにしたことを特徴とするラジオ受信機。A radio receiver that can receive general radio broadcasts is equipped with a tuning circuit that tunes to a predetermined number of unique frequencies, performs a search to sequentially switch to the unique frequencies, and also performs a search to sequentially switch to the unique frequencies, and a roadside communication broadcast receiving circuit that demodulates the signal, a broadcast detection circuit that detects the presence or absence of an external radio wave of the specific frequency, and a detection signal output from the broadcast detection circuit when the external radio wave of the specific frequency arrives, A reception frequency control circuit that performs mode switching control between a search reception mode in which the tuned frequency of the reception circuit is sequentially switched and a spot reception mode in which the frequency is fixed to a unique frequency of the tuned radio wave, and a roadside communication broadcast reception circuit in the spot reception mode. Based on the demodulation output detection circuit that detects the audio signal demodulated by The system is equipped with an audio signal switching circuit that switches to the audio signal, so that when an external radio wave with a frequency unique to the roadside communication broadcast arrives while listening to the general radio broadcast, the audio signal is automatically switched from the general radio broadcast to the audio signal of the roadside communication broadcast. A radio receiver characterized by:
