し得るように構成したことを特徴とする受信機。A receiver comprising first and second variable frequency local oscillators and a notch filter for obtaining an arbitrary passband width, the receiver comprising: a control unit dedicated to setting the notch filter; a fixed local oscillator; a third variable local oscillator for continuously varying the pitch height of the fixed local oscillator; and switching means for selectively connecting the output of the fixed local oscillator and the output of the third local oscillator to the detection stage. A receiver characterized in that the passband width, the notch filter, and the pitch height at the time of CW reception can be set independently.
