I'll have to dig around to find it, but I read a piece in one of the broadcast industry trades that said that the re-pack has been a rushed mess. The gist of it was that broadcasters are being hustled to their new DTV channels and that the crews and infrastructure required to facilitate the moves are in very short supply. The result is all kinds of temporary (STA) arrangements that get the station on to their new channel, but not at the power, height etc that they will ultimately be (and were previously at), as Tim points out here. So, the takeaway is that the end results of the re-pack are still years away. Note that this could go either way in terms of the local RF picture. For example, say a station has had to use a temporary transmitter on the roof of their studio until they can get back on to their tower, ten miles out of town. If your venue happens to be a club or theater near the TV studio, you may be seeing that DTV channel at a significant level right now, but it may diminish after the tower move. Or...it could get worse.

I scanned the area with my RF Explorer and seems like I have a TV station that hasn't moved?

Anyways, doesn't look like a good idea anymore.
Hi Nathan, I was just scrolling through this thread and re-read this one. This DTV station will absolutely move as there will be NO DTV above Ch-36 going forward. Not sure where you are located, so can't look up the re-pack info for you, but this DTV channel should not be a detriment to your plan to use a properly re-banded system in the duplex gap if you meet all the other criteria that Henry mentioned.

Thanks Ike, I appreciate the response.

While I vacillated the unit sold. And I bought more qlx-d g50 band. The 1U would have been lovely, but I'm content with 8ch of qlx-d for now :)

It's channel 45, WVUP-CD in Tallahassee.  Scheduled for phase 8, which means it'll probably move (to channel 30) in March.
