ABSTRACT:
Many broadcast stations transmit their programs via a variety of different frequencies. The invention relates to monitoring alternative frequencies during the reception of a broadcast signal at a present frequency. Whenever the broadcast signal at an alternative frequency is checked, the receiver's gain is instantaneously switched from a present gain value corresponding to the present frequency to a second gain value corresponding to the alternative frequency. The second gain value is adapted to the supposed signal strength of the broadcast signal at the alternative frequency.
