Abstract
In a tuning method, a commanded-tuning loop (CTL) tunes a receiver (REC) on the basis of a tuning command (TC) and a self-tuning loop (STL) tunes the receiver on the basis of a reception signal. To resolve a tuning conflict between the loops, one of the loops (CTL or STL) is calibrated (CAL) with respect to the other loop (STL or JKR CTL). Preferably, the commanded-tuning loop (CTL) is in an active state when the self-tuning loop (STL) is in-lock. This allows good reception under dynamic reception conditions.
