About 2.4% of Louisville households are not prepared for this week's digital TV transition.FCC spokesperson Rick Kaplan says Louisville is one of the best-prepared cities for Friday's transition, but some households won't make the switch until they have no choice."There will be a certain quotient of people you can't do anything about and they're going to wake up on the 12th and have no picture and they're going to scramble to take action. But you can't say they weren't well-warned," he says.Kaplan says vouchers for converter boxes are still available, and the FCC will install the boxes in homes before or after the transition.All of the major networks in Louisville except for the CW and KET are still broadcasting analog signals.For more information on the transition and the converter installation program, click here.
