Abstract
Abstract Remote tuning system for a plurality of electronic services employs a common tuning control, function selector, and indicator. Tuning is accomplished by selectively applying pulses of variable repetition rate to electronic counter and code converting means the output of which causes a selected electronic service to be step-tuned at a rate determined by repetition rate of the oscillator.
