Abstract

PURPOSE: To obtain an economical and easy-to-use preset channel selector, by preventing the presetting of the same station by making it possible to know whether a station in reception is preset or not.
CONSTITUTION: With switch 50 ON, FF51 is set to make its output high in level, and consequently a clock pulse is applied to the up input of up-down counter 47 via gate 48, thereby varying the division ratio of variable divider 21. If a receiving station exists when the content of counter 47 reaches a certain value, a signal appearing at the output of intermediate frequency amplifier circuit 17 resets FF51 to make its output low in level and any pulse is not applied to counter 47 via gate 48. When the content of counter 47 has been written to memory 42 yet at this time, light emitting element 57 comes on and when not, it stays unlighten. In this way, it is made possible to make a comparison between a tuning frequency stored in memory 42 and that obtained through the operation.
