Abstract
An improved satellite receiver system is provided which automatically locates audio signals among the various audio subcarriers received by an earth station; manual scanning of transmissions received from different transponders in order to locate audio signals embedded therein is eliminated. The improved receiver system does not require any input data characterizing the frequencies or bandwidth of the incoming audio signals and locates desired audio subcarriers in response to a command signal, without need for any manual intervention after generation of the command signal.
