Z-band VHF-TV broadcasting in which TV signal waves and audio FM modulated waves are arranged is input, this input signal is converted into an intermediate frequency signal by the oscillation signal of the first local oscillator, and the intermediate frequency signal is transmitted to the second local oscillator. In a tuner that outputs several designated output intermediate frequency signals using an oscillation signal from an oscillator, the oscillation frequency of a second local oscillator is varied and outputted using an external selection channel, and the oscillation frequency is varied depending on the content of the input VHF signal. A tuner characterized by varying the frequency of an output intermediate frequency signal.
