I see on the FCC website that WGSR-LP has filed for channel 47 for DTV with 15kw on a tower at NC150/US29 at Brown Summit (the old WWMO Tower?) at about 450 ft above ground. The pattern is pretty much to the north but the coverage listed covers just about all of the eastern half of the Triad and definately gets coverage over Time-Warner's tower in Greensboro.
