ABSTRACT:
A synthesizer type receiver where frequency conversion of a received signal is performed by the use of a signal formed in a PLL, and the signal frequency is changed by changing the frequency division ratio of a variable frequency divider in the PLL to thereby change the received frequency. The receiver comprises a detector for detecting reception of a broadcast wave signal; a memory where data areas correspond respectively to a plurality of station selector keys; and a control unit having a data table with a data section relative to frequencies of broadcasting stations receivable in divided areas of the whole area where the receiver is to be used. In a preset mode, the reception frequency band is scanned by changing the frequency of the signal through change of the frequency division ratio, and when the reception frequency at the time of detection of the broadcast wave signal by the detector during the scan is included in the frequency data stored in any preselected divided area, the data relative to the reception frequency is stored in the data area of the memory, and the broadcasting station being currently received is preset in the station selector key corresponding to the data stored area in accordance with the storage.
