ナ付ＦＭ受信機。 A plurality of antennas, an antenna switching switch that selects each antenna each time a switching signal is input, an FM receiving circuit that receives the received signal of the antenna selected by this switch, and FM demodulation of this receiving circuit. A filter that follows the circuit and removes the frequency component of the signal to be received, and a level discrimination circuit that generates a level discrimination signal when the output signal level of this filter exceeds a reference level, and uses this level discrimination signal to generate a level discrimination signal. An FM receiver with a diversity antenna configured to operate the changeover switch.
