Abstract

PURPOSE:To prevent erroneous stopping due to adjacent stations having high electric field strength, by controlling an automatic tuning continuity discriminating circuit newly provided, with the level of a high frequency component included in a reception detecting signal. CONSTITUTION:When an automatic tuning operation of a controller circuit 12 is stopped as being tuned to a desired reception frequency signal, an automatic tuning release signal is applied to a switch controlling circuit 20, which turns on a switching circuit 19 for a prescribed time. In this case, if tuning is made to an adjacent station by mistake, the level of high frequency component obtained from a detection stage 7 via a high-pass filter 21 is increased and a specified DC voltage is obtained from an amplifying detection circuit 22. This DC voltage is applied to the controller circuit 12 via the switch 19 so that the automatic tuning operation of the controller circuit 12 can be continued, allowing correct tuning to an objective broadcast station.
