Abstract

PURPOSE:To increase the operationability of channel selection, by enabling other channel selection operation after the execution of programed reception even within the set time by the program. CONSTITUTION:An arbitrary programed time is set to a time memory section 13 with the signal input from an operation section 12, and the channel selection key information corresponding to the time is stored in the channel selection key memory section 14 with external operation. When one time among the times stored in the time memory section 13 is in agreement with the time of the clock 16, a coincidence signal is output from the time agreement detection section 15 and a one shot multivibrator 17 starts operation. Thus, by the period when the one shot multivibrator 17 is output, with the channel selection key information of the channel selection key memory section 14 corresponding to the time memory section 13, the reception information such as band, frequency etc., is read out from the memory section and set to the counter 11 for setting the frequency dividing ratio.
