1. A method for synchronizing carrier phases of a group of co-channel amplitude-modulated broadcast signals, the method comprising:

  • feeding a reference phase output from a multichannel receiver to a phase lock loop;

    substantially eliminating audible and sub-audible beats between a local desired station'"'"'s carrier signal and one or more distant interfering stations'"'"' carriers; and

    maintaining a predetermined phase relationship between a local desired station'"'"'s carrier signal and one or more distant interfering stations'"'"' carriers.
