WUNE- 17 has a very strong signal, and it may be due more to tower height in the mountains, rather than power level. I am not sure if they are full power 1000kw, but they do put out a good signal. I receive them here in northern Greenville, SC with a UHF yagi antenna in the attic. So in Charlotte, if you had a 91XG, MXU59, or 9095, you would probably be able to pick it up. Not so sure if a DB4, 4221, or CS2 would quite be able to get it, which would probably be a more typical antenna for the Charlotte market.
