Thank you for the info. I have been following the other two threads as well, but started posting here as there is more and better info as relates to TWC, and in particular more frequent posts from Diana Smith. I do agree my OTA problem with WFXB is more Grand Strand related, so I put a post in the MB thread too.
Charleston is predominantly a Comcast market. We are technically in their DMA, but we are on TWC here, and get a mixed bag of channels. WIS is one of two NBC stations TWC carries here, for example, so I guess I feel some ties to the Columbia thread, but we are kinda in the middle of all three.
