Trying to fit together the cookie cutter, here are a few observations between the markets. If WOLO in Columbia is indeed moving to RF7, then it would appear if WSPA may be moving from 7 to another channel, as there would be mutual interference since the regions overlap too close. And since WYFF is moving to 30, then the Shelby translator for WSOC may have to move.
Regarding WIS and WBTV, so far Raycom is being silent in this region, whereas they have announced other markets such as Virginia and Wilmington, NC. Hopefully they can remain on 10 and 23, but that remains to be seen. However there is a monkey wrench concerning WBTV, and it is due to one of their own stations. Apparently WECT in Wilmington is moving to 23, the same current channel as WBTV. Perhaps it is far enough away so WBTV may not have to change, and WECT is lower power about 400kw. And perhaps they could use a directional antenna to prevent same channel interference with WBTV. We shall see what happens here. Hopefully their good, strong signal can be preserved.
And regarding the power levels, so far it seems to be a bit lower for many of the new channels in various markets. And not necessarily because of the Dipole-Factor. Because currently there are numerous 1000kw stations above 23 that seem to be reduced after the repack. Possibly to avoid adjacent market interference since the broadcast spectrum has shrunk. Hopefully current coverage areas can be maintained. But this may be a concern for viewers in the fringe areas or border markets.
But of course this is still somewhat speculation until the engineers or the FCC are free to comment and explain. But at least some clues are now starting to trickle out.
