Abstract

PURPOSE:To omit a time required for executing to discriminate a detection result of a timing detection means, by executing to discriminate a detection result of the tuning detection means thereafter, in accordance with a detection result of a receiving signal detection means. CONSTITUTION:A microprocessor 8 for controlling a front end part 1 containing a frequency synthesizing circuit receives an output signal (c) through an amplitude detector 4 and a receiving signal detection means 5. To an AND circuit 7 is inputted an output signal (e) through a frequency detector 3 and a tuning detection means 6. When the processor 8 has detected the signal (c) in the vicinity of broadcasting frequency, an output signal (f) of a circuit 7 is read. When this signal exists, sweep is stopped.
