ABSTRACT:
An information or broadcast receiving system and a control method therefor are provided for preventing a switch noise generated during the switching of antennas of a receiver provided with a plurality of switchable antennas from deteriorating a receptive state of an other receiver. When a detector 62 of a main controller 3 detects that a radio 1 is receiving an AM broadcast, a signal output device 63 causes an FM multiplex receiver 2 to stop the switching of a main antenna 31 and an auxiliary antenna 32 by a diversity circuit 33 and to select the main antenna 31.
