ABSTRACT:
A radio receiver of synthesizer type having a phase-locked loop therein and capable of selecting a desired broadcasting station by frequency conversion of a reception signal in conformity with an oscillation signal obtained from the phase-locked loop. The receiver includes a data table including frequency data for receiving programs from broadcasting stations, and time data indicative of the broadcast start time of each station; a timer circuit; a memory for the timer; and station select keys. When desired frequency data has been selected out of the data table by depressing one of the select keys for timer reservation, the selected frequency data and the time data corresponding thereto are read out from the data table and are written in the timer memory.
