Abstract

본 발명은 라디오방송마다 지역별로 해당 기준주파수를 메모리에 저장해둔 상태에서 특정방송국을 지정해두면, 그 지역에서 수신되는 주파수와 메모리에 저장되어 있는 지정한 방송국의 기준주파수를 계속적으로 비교하여 같을 경우에 수신되는 주파수를 출력하도록함으로써, 어느 특정 방송국을 지정해두면 그 지역에 해당되는 방송주파수를 자동적으로 찾아내어 출력하도록 한 라디오방송 자동수신장치에 관한 것이다.According to the present invention, if a specific broadcasting station is designated in a state in which a corresponding reference frequency is stored in a memory for each radio broadcast, the frequency received in the region and the reference frequency of the designated broadcasting station stored in the memory are continuously compared to each other. The present invention relates to an automatic radio broadcasting receiver for automatically finding and outputting a broadcasting frequency corresponding to a specific station by designating a specific broadcasting station.
