Abstract

PURPOSE:To prevent rasping noise due to the fluctuation in a DC level, by muting at station switching and holding of an output of an intermediate frequency amplifier to the level just before the switching. CONSTITUTION:An audio interruption circuit 7 is operated with a signal from a control section 12, a tuning data 13 is replaced from a present station area 14 to an inspection station area 15, and the inspection station is received. Next, the reception level of the present and inspection stations is compared at a comparison circuit 6, the result is transmitted to a control section 12 and the rewrite of tuning data and the release of audio interruption can be made. An interruption circuit 19 connected to a time constant circuit consisting of a capacitor 20 and a resistor 21 is operative at the operation of the circuit 7, and the DC level just before the interruption of audio can be kept during the interruption also.
