Claims (1)
引を行うラジオ受信機に於いて、中間周波増幅器からの
受信信号を増幅し且っ掃引停止手段を構成する掃引停止
用の増幅器を掃引中のみ動作させる手段を設けたことを
特徴とするラジオ受信機。In a radio receiver in which the local oscillator circuit is configured with a phase-locked loop PLL and performs automatic sweeping, the sweep stop amplifier that amplifies the received signal from the intermediate frequency amplifier and constitutes the sweep stop means is used only during sweeping. A radio receiver characterized in that it is provided with means for operating it.
