Kentucky Educational Television will turned off its analog signals early this morning. But a digital converter box may not be enough for some viewers.Viewers without cable or satellite television will need converter boxes or newer model TVs in order to watch the digital signals. But KET spokesperson Tim Bischoff says viewers in mountainous or remote areas may need to replace or move the antennas those boxes and TVs plug into."Some folks who maybe would've been able to get by with rabbit ears on top of their television before will find that they may need an antenna in the attic or an antenna on the roof to continue to receive free, over-the-air television," he says.KET joins CW channel 34 in Louisville in turning off analog signals before the June 12th transition deadline. The other stations in Louisville will keep broadcasting in both analog and digital until then.
