PURPOSE:To read out data of a relatively higher receiving level out of plural data, which are stored during the selection of a channel selection key, to receive data of the station, by storing preliminarily tuning data of plural stations of the channel selection key. CONSTITUTION:A channel selection device 9 is provided with channel selection key 91 and 92, and a control part 11 is connected to the device 9, and tuning data of plural stations are stored in a data area of a memory device 10. Optional data in the device 10 is read out into a memory 12 for data of the current station by the operation of the channel selection key 91, and data in the memory 12 is stored in an area 13 for data of the current station, and the next data is stored in an area 14 for data of a check station. Data of the area 13 is applied to a varactor diode 16 of a tuner 2 through a tuning data generating circuit 15 of the PLL synthesizer constitution. When the chennel selection key 91 is depressed, receiving is started with data of the area 13, and the receiving state of the area 14 is compared continuously by a comparing circuit 5, and the signal of a higher level is received. |
