I thought WLBT was on Channel 30.
Down in Hattiesburg, WDAM originally had channel 28, but they were able to move to channel 7 once WLBT vacated it. It still is that way today with no issues, and they even are receivable in my neck of the woods when the skies cooperate. 28 ended up on WMAW (PBS-MPB) in Meridian, after having to move from 44 during the repack.
I used to get WLBT on 30, but it was overruled by the local PBS station (WEIQ/APT) that also moved to 30 during the repack.
Biloxi and New Orleans were failed attempts to VHF on their original channels for WLOX and WVUE. WLOX was particularly short-spaced to Baton Rouge (WBRZ) and both stations had many complaints, so they switched back to their original DTV alottments of 39 and 29. WVUE is still on 29 while WLOX made the early switch to 32 at the behest of the buyer of their spectrum in the area....I believe it was TMobile?
