Abstract

PURPOSE:To prevent erroneous decision of a reception level by permitting the deciding operation of a reception-level deciding circuit only during the output period of a reception-state signal. CONSTITUTION:Under the command of a channel selector 12, a control circuit 10 varies the tuning voltage of a tuning-voltage generating circuit 7. Once detecting the reception level of an intermediate-frequency amplifying circuit 3 exceeding a prescribed value, a stop circuit 8 outputs a negative pulse (stop signal) showing a narrow-band reception state, and it is inverted by an inverting circuit 9 to apply the resulting signal to the control circuit 10. Then, the control circuit 10 stops variations in tuning voltage. Further, the output of a signal meter driving circuit is led to a reception-level deciding circuit to be compared with reference potentials 16 and 17, and the deciding operation is enabled through the operation of a diode 15 only when the stop signal is present.
