特徴とするラジオ受信機。 An integrated circuit in which at least a signal meter circuit that outputs AM and FM signal meter signals from the same terminal and an FM band muting circuit that outputs a muting signal when a predetermined band deviates from the tuned frequency are housed in the same package, and a PLL. In the radio receiver, the radio receiver has a control circuit that controls a configured local oscillator to perform an automatic sweep and detects a stop signal to stop the automatic sweep, and a selection means that selects between AM and FM. mutating signal as a stop signal of the control circuit, and between the signal meter terminal of the integrated circuit and the stop terminal of the control circuit, when the selection means selects FM, the signal meter signal is invalidated. A radio receiver characterized in that a means is provided.
