Radio receiver having second receiver part for avoiding interference signals

A radio receiver comprising:

• a first radio receiving part having means for receiving a desired radio signal of a given frequency transmitted from a broadcasting station, means for generating a first local oscillation frequency, and means for mixing the received radio signal with the generated first local oscillation frequency to obtain an intermediate frequency (IF) signal corresponding to the desired signal;
• a first detector connected to an output of the first radio receiving part for detecting a field intensity of the desired signal received by the first radio receiving part;
• a second radio receiving part having means for receiving a disturbing radio signal having a frequency adjacent the frequency of the desired radio signal;
• a second detector connected to an output of the second radio receiving part for detecting a field intensity of the disturbing signal received by the second radio receiving part;
• a receiving frequency controller connected to the first and second detectors having means for comparing the field intensity of the desired signal with the field intensity of the disturbing signal, and for providing a first control signal for shifting the IF frequency of the desired signal in a direction away from the frequency of the disturbing signal based upon said comparing of field intensities;
• and
• a first local oscillation frequency controller receiving the first control signal output of the receiving frequency controller and providing an output to the first radio receiving part for controlling said means for generating the first local oscillation frequency so as to shift the IF frequency of the desired signal in the direction away from the frequency of the disturbing signal.
