In a radio receiver for receiving a particular radio signal of a particular frequency with an electric field strength among a plurality of radio signals of different frequencies, a temperature detector produces a detected temperature signal representative of an ambient temperature of the radio receiver. A correcting signal producing unit produces a correcting signal representative of a control value determined by the detected temperature signal and a particular control signal produced by a frequency controller to indicate a local frequency for the particular frequency. A correcting unit corrects, according to the correcting signal, an electric field strength signal which is produced by an electric field strength detector to represent the electric field strength detected in a detected signal produced by a detector by detecting the particular radio signal in response to the particular control signal.
