路。A converter is provided between an intermediate frequency amplification circuit consisting of an IF filter and an amplifier with the necessary bandwidth and an FM detection circuit, and the oscillation frequency of the local oscillator of the converter and the converter provided before the intermediate frequency amplification circuit are provided. The oscillation frequency of the local oscillator can be adjusted in conjunction with the oscillation frequency of the local oscillator, and the intermediate frequency is changed by increasing one oscillation frequency and decreasing the other oscillation frequency by the same frequency according to the degree of interference from adjacent stations. An FM interference removal circuit characterized in that it removes nearby station interference.
