Here's how complicated these rules are, and why an expert consultant is worth every penny:
Even if WKBC could have found a site closer to Charlotte, there's another FCC rule that comes into play, and that's the "rural radio" policy.
After so many stations were moved into urban areas from rural areas, the FCC closed that barn door a decade or so ago. If you're proposing a move like this now, you have submit a showing that your new 70 dBu (very strong city-grade) signal will not cover more than 50 percent of the urbanized area you're moving into.
Not only that, you have to show that there is no other usable tower site where your proposed station would meet all the spacing rules AND would cover more than 50 percent of the urbanized area.
WKBC's application includes that showing, and it's well done. (It was actually the first thing I looked at in their filing because I knew it would be the hardest thing for them to show )
