In an FM wide receiver equipped with a tuning indicator drive circuit, there is a resistor for signal attenuation provided in the path of the FM detection signal, a bypass circuit using a diode provided in parallel with this resistor, and a bypass circuit for TV audio broadcasting. A switching element is turned on when tuned to the reception band, and only when the level of the tuning signal supplied through this switching element exceeds a reference value, a positive bias is applied to the diode constituting the bypass circuit to make it conductive. By letting
An FM wide receiver that prevents an increase in the inter-station noise level when receiving TV audio broadcasts.
