I live in the Columbus/Tupelo, MS region and I receive the following locals. Channel 4, 9, 12, 14, 27, and 45. I had to move the dish because of an overgrown tree and now that I've reconnected it, I get everything perfect, except for Ch. 4 and 12. I know these locals are spot beamed and the signal is probably just a little harder to find for these than others, but I would think that all locals are all coming from the same transponder. THe only thing different is that 9/14/27/45 all show coming from the same area, Tupelo. And 4/12 show coming out of Columbus....but the signal can't be that "tight" can it? Or could it be from 2 transponders? Does anyone know which transponder(s) these are coming from and I'll check on my signal strenght meter? By the way, This is D*TV. Thanks!
