A receiver which includes: a first memory including one set of nine data areas for storing frequency data for broadcast stations broadcasting a common broadcasting program at difference frequencies for each of a plurality of station selecting keys, a second memory including a first and a second data areas for storing the frequency data transferred from that set of data areas of the first memory selected by one of the keys, and a tuner tuned to a first broadcast station determined by the frequency data in the first data area of the second memory through a tuning voltage generator. By temporarily muting the first station, a second broadcast station is compared with the first station as to the average of the sensed reception level. This process is repeated with the frequency data in the selected set of the data areas of the first memory after their successive transfer to the latter. The tuner is then tuned to that station having a reception level which is higher than that of the first station. The tuning voltage generator may be formed of a PLL syntherizer having a variable bandwidth with the frequency data replaced by a ratio of the frequency division. |
