This was during the energy crisis of 1973-74. The federal government encouraged states to go on DST and Ohio did. Kentucky stayed on standard time (putting the Louisville and Lexington stations on a Central Time schedule; I suspect that the reason was, in part, that, being that far west, the sun would not come up before 9 AM (EDT), an experience we had in Georgia, which did go on EDT.
Lexington was on Eastern Time in the '50s; Louisville did not move from Central to Eastern until 1961. My sixth-grade teacher was from Louisville; she sometimes mentioned that she remembered when the changeover took place. This is why whenever you see my pre-'61 Kentucky retros, you will note that I mention that Lexington and Cincinnati stations are listed Eastern time; Louisville and Evansville, Central time.
At any rate, come 1975, the Louisville and Lexington stations were back on an Eastern time schedule.
