Abstract
A radio receiver operates primarily in a first operating mode to process received signals (410). When a carrier signal detect is triggered while in the first operating mode (415, 420), the receiver temporarily operates in a second operating mode which has receiver parameters selected to reduce carrier detect falsing when compared to the first operating mode (430). Preferably, in the second operating mode, the receiver's frequency and time response characteristics are modified to facilitate carrier squelch detection. Carrier squelch is performed if a carrier signal detect is triggered while the receiver operates in the second operating mode (440, 450, 460, 470).
