Abstract
In order to tune a radio receiver (10) to an optimal tuning frequency it is found the critical frequency closest to the current tuning frequency (60) at which the radio receiver loses the locking to the clock frequency of the received signal, and, if necessary (62), the tuning frequency is corrected away from the critical frequency found. The control block (13) of the radio receiver comprises means for adjusting the tuning of the reception part (11) in response to the information (17) indicating whether the locking to the clock frequency is on. The search for the critical frequency may be performed in on or two stages and alternately on both sides of the current tuning frequency or first on one side and then on the other.
