Reducing the cost and size of an FM radio receiver for receiving the North American weather band is aimed. An intermediate-frequency bandpass filter (IFBPF (80)) for limiting the band of a reception signal converted to an intermediate signal is configured with a variable passband width W.sub.F. W.sub.F is varied in accordance with reception conditions. When the user selects to receive signals in the weather band, a microcomputer (54) switches the tuning frequencies and sets W.sub.F to a lower limit of a range variable by the IFBPF (80). Adjacent-channel interference can thereby be suppressed during reception in the weather band, which has a smaller channel step than do other bands. In this configuration, there is no need to externally mount an expensive crystal filter to an IC for an FM tuner.
