A broadband receiver exhibiting reduced interference to a frequency counter caused by a local oscillator. The broadband receiver is arranged for detecting a radio signal of strong reception intensity and receiving the radio signal, and in a specific configuration includes: a reception system including an antenna for receiving the radio signal, a local oscillator for outputting a local oscillation signal, a frequency mixer for converting the radio signal to an intermediate frequency, and a demodulator for demodulating the intermediate frequency; a frequency counter for measuring the frequency of a radio signal having strong reception intensity; a control section for controlling the oscillation frequency of the local oscillator in such a manner that the radio signal having a strong reception intensity is demodulated by the reception system; and a local oscillator halting section for halting the oscillation of the local oscillator during the measurement of the frequency of the radio signal by the frequency counter.
