This invention relates to a receiver with a search circuit that includes a RF-AGC circuit for gain control of a RF-AMP and for generating a control signal according to an output signal of the RF-AMP, a search circuit including a reception condition detector for generating the reception condition signal based on the output signal of a RF-AMP, a sensitivity change circuit for receiving the control signal from a RF-AGC circuit and for changing the sensitivity of the search circuit so as to compensate a loss of the reception condition signal caused by the RF-AGC circuit, and a station detector for outputting a station detection signal based on a reception condition signal and a reference signal.
