I've been up since 3:45AM and there's been nothing but a black screen on WUVN/18 since then. I know they are still on the air because I'm can still pick up the ghosting from Channel 18 on Cable Channel 69. I know it's a problem with 18 and not with COX Cable as the ghosting I can see is a blank screen. Usually I can see whatever programming Channel 18 is showing in the ghosting.
