PURPOSE:To enable to perform the selection of a plurality of broadcasts completely and automatically, by providing the preset reception section receiving the desired broadcast station at desired time and converting the reception signal into specific frequency, and feeding and reproducing the signal from the reception section to the specified circuit in the radio reception section. CONSTITUTION:Desired time and broadcast station are stored in the programmable timer 4 in advance, control signals S1, S2 are outputted to the tuning circuit 5 and the local oscillation circuit 6, and the control signal S3 is outputted to the radio reception section 3 and the power supply is turned on. When the frequency of a station is received, the reception signal is mixed 7, detected 9 via IF8 and modulated 10 and fed to the reception section 3. Next, at separate time stored in the timer 4, the control signals S1, S2, S3 are outputted and another broadcast station is received. Thus, the selection of a plurality of broadcast stations can completely and automatically be made. |
