受信機。In an automatic sweep receiver that is equipped with a level determination circuit that determines the output level of an intermediate frequency amplification circuit and that automatically stops sweeping according to the output signal of the circuit, a reference voltage is input to a first terminal, and a reference voltage is input to a first terminal. a comparator which inputs the output of the intermediate frequency amplification circuit to a second terminal via a first resistive element; and a second resistive element connected in series between the second terminal of the comparator and one power supply terminal. The level determination circuit is configured with a connected semiconductor switch, and the semiconductor switch is turned on and off in response to a mode switching signal between a short-distance tuning mode and a long-distance tuning mode. Automatic sweep receiver.
