Abstract
The disclosure relates to a radio which prevents the level of a signal transmitted from a desired broadcasting station from being suppressed by the operation of a broad band automatic gain control circuit in the presence of an interference signal. The radio comprises a first detector for detecting the intensity of the electric field of a received signal; a second detector for detecting whether or not the broad band automatic gain control is operating; and a device for changing the tuning condition of a radio frequency tuning circuit in a small extend in response to the signals outputted from the first and second detectors.
