Matt Smith said:significantly reducing the signal over the less-populated areas of Caswell (NC) and Halifax (VA) Counties.
We won't know for sure until we're on the air, but it should give a reasonably good signal for folks with antennas in Rocky Mount, Ferrum and maybe Smith Mountain Lake. Who knows, you might get a viewable signal where you live.
Those two statements are pretty contradictory, since I live in the same direction as Halifax. (I'm to its east northeast) I've seen digital TV work well at low power levels, and I may still be surprised, but 0.7 kW on a signal that's not line-of-sight is feeling pretty unlikely. TVFool does not even show it. I used to receive video (but not audio) from W18BG analog before WDBJ-DT signed on in 2002, but I'm not sure how well the signal would hold together at reduced power and in digital.
