CARRIER_CURRENT_TV_CONTROL
Low-power oscillator provides both unmodulated and 60-cps modulated signals for power-line carrier. current transmission to control receiver in tv set. Unmodulated carrier having preset duration controls channel selection, while modulated carrier controls sound level. System operates on one of four nonadjacent frequencies (52.5, 57.5, 67.5, and 73.5 kc) to ovoid interaction between nearby systems,-J. R. Banker and C. H.
