A proposal to delay the national digital television switchover could cost local television stations tens of thousands of dollars if it’s enacted.Nearly all Louisville area TV stations are currently broadcasting both digital and analog signals. WLKY General Manager Glenn Haygood says altogether, Louisville’s stations are spending about $50,000 a month to keep the analog signals going.And he says stations have been advertising the February 17th switchover for months.“If all of a sudden a couple of weeks before the transition date actually gets here, we reverse course on that and start giving people a different now, I’m very concerned that it’s going to cause a tremendous amount of confusion on the part of viewers as to exactly what’s going on," he says.President-Elect Barack Obama and several other politicians are pushing to delay the DTV switchover. They say not enough people know about the transition and there’s not enough money to fund vouchers for converter boxes before February 17th.
