Has anyone ever pinpointed when the last full-power network affiliate relying on an off-air pickup for a network feed switched to coaxial or microwave? (Not official full-time "satellite" stations, but isolated small-market stations off the Long Lines grid.) I know a few of these were around at least into the early 70's. When my family first moved to Florida in 1971, WCJB Gainesville was still picking up their ABC programming off-air from WJKS Jacksonville. (As evidenced by occasional WJKS IDs during football games and such.)
