发明名称 Synthesizer receiver for automatically tuning master stations and associated satellite stations in specified geographical areas
摘要 A synthesizer receiver automatically tunes to master stations and associated satellite stations in specified geographical areas by utilizing a data table having the master station data corresponding to a plurality of master frequencies associated with broadcasting stations that are received in each of the plurality of divided geographical areas and also containing satellite data corresponding to one or more satellite frequencies individually associated with each one of the plurality of master stations in the divided geographical areas when such a master station does, in fact, have satellite stations associated with it. When one of the data areas containing the master station and satellite station data for the specified geographical areas is selected, the data is read out and used to control a phase-locked loop of the synthesizer receiver to tune to that station. If the master station is not available, the satellite station can be selected.
