A system for automatically tuning a primary broadcast receiver using a secondary broadcast receiver to receive a first broadcast signal corresponding to a source of an origin program, one or more program transition detectors to monitor first broadcast signal tuned by the secondary broadcast receiver to determine and signal a transition from a non-original program content to origin program content while a user views or hears alternate programming from a primary broadcast receiver, and automatically tuning of the primary broadcast receiver to the first broadcast signal upon detection by the program transition detector that one or more of user-specific tune conditions have been met.
