Abstract

PURPOSE:To get rid of a noise in case of switching, etc., by comparing a receiving level of a present receiving station with a receiving level of a nonpresent receiving station by interrupting a voice, switching it to a station whose receiving level is high, and also changing an attack time of a muting circuit when an electric field is varied, and at the time of detuning. CONSTITUTION:When an output of an averaging circuit 5 of a receiving level becomes a prescribed level or below, a signal is supplied to a voice interrupting circuit 7 from a control part 12, and a voice is interrupted. Subsequently, a present station data of a present data memory 13 is replaced with an inspecting station data 15, and tuning voltage is generated by the inspecting station data 15. A receiving level in this case is compared with a level of the averaging circuit 5 by a comparing circuit 6, and the present station data is changed to a station whose receiving state is good. When receiving the present station, the attack time of the muting circuit is shortened by switching a switch 22 so as to follow the input signal, and when receiving the inspecting station, said time is lengthened in reverse.
