I had a similar problem as you. I live 3 miles north of the Wolfchase mall. I would constantly get 100% on CBS and then BAD dropouts if any signal on WMC and WPTY. Once I turned my antenna the way of WMC and WPTY, I lost CBS. I have a Terk 35 antenna up in the attic of my 2 story house. After getting extremely frustrated, since this was very near the NCAA championship, I ended up stumbling upon the fix. I at first had both ends of the antenna hung from rope, pretty much flat. I undid the bottom rope, and now have the antenna pointing straight up in the air. The backwards Y(yagi I think) is at the top. The antenna I'm using is small enuf to be able to have it like that. Maybe this will help you out, cause I know how frustrating it can be.
About WMC, the contact there is Derek McMillian, DMcMillian@wmctv.com
if you want to complain about their digital feed. I posted earlier about their hardware problems. But I'm sure they could use a little more voices to get them going. :-)
Last, who is the person to contact at FOX, WHBQ about the new HD for FOX stations?? I sent a message on their website to please get it to the correct person, but haven't heard anything back yet. I remember someone posted that they were in someones office there, but cant remember who it was here. I'm anxious to hear when we should expect to get the 720 feed or if the new tower they are having built will be suited for it.
