The digital television transition was Friday morning but some analog signals are still on the air in Louisville.Starting Saturday, WLKY-TV will participate in an FCC program to help stragglers make the transition to DTV. General Manager Glenn Haygood says the station will broadcast transition information for the next 30 days."We'll insert instead a 15 minute loop that is a DTV education message," he says. "Half of it is in English and the other half of it is in Spanish."A Nielsen report estimated that 2.5 percent of households in Louisville were not ready for today's (Friday's) transition, but Haygood says calls to his station have been mostly from people have prepared for the switch, but are having trouble with their converter boxes."That's the good news," he says. "Everybody is aware of it—it's really just an issue of technically helping people right now."The station's analog signal will also serve as an emergency channel in the case of storms or other urgent situations.
