求の範囲第１項記載のラジオ受信機。[Claims for Utility Model Registration] (1) A local oscillation circuit configured with a PLL circuit, which includes reception level detection means for detecting the reception level of a receiving station, performs automatic sweeping, and stops sweeping based on a search stop signal. A first means of
performing an automatic sweep from the lowest frequency to the highest frequency, and detecting the received level based on the received level detecting means when a search stop signal is generated;
A radio receiver comprising: second means for tuning to a frequency with the highest reception level after automatic sweeping; and selection means for selecting one of the first means and the second means. (2) The utility model registration according to claim 1, wherein the selection means has a selection key, and selects one of the first means and the second means depending on the operation time of the selection key. radio receiver.
