させることを特徴とする放送信号受信機。 In a broadcast signal receiver that receives a desired broadcast signal by applying a tuning voltage obtained by operating a tuning volume to an electronic tuning circuit, a changeover switch that can be switched in conjunction with the tuning volume is provided, and the switch can be switched in conjunction with the tuning volume. The switch is switched between when receiving a high band TV broadcast signal and when receiving a low band broadcast signal, and the transistor connected to the variable terminal of the tuning volume is controlled, and the tuning voltage is switched to the TV broadcast signal of the channel band receiving the tuning voltage. A broadcast signal receiver characterized in that the signal can be changed by tilting the signal.
