Description
Summary:Digital tuning system approaches to AM-FM broadcast receivers are becoming increasingly popular as manufacturers are finding lower component costs and increased features give their products greater appeal. Operational features of a digitally tuned receiver include: * Precise tuning of station frequency * Display of exact receive frequency * Keyboard entry of station frequency * Storage of multiple stations in memory * Pushbutton up/down scan through the band * Pushbutton search (stop on next station) * Power on to last station * Provision for time of day clock * Static drive of LED for noise-free operation * Able to address CB synthesizer
