It could be a requirement of the tower owner. Or maybe the 100 meter spot was unavailable at the time the originally went up there and now it's available. It won't cost them much to make this change. As far as Radio One simulcasts, do any of their other simulcasts overlap as much as 92.7 and 100.9? 100.9's contour is almost 100% within 92.7 post upgrade contour. The only simulcast I am familiar with is Foxy in Raleigh. The 107 frequency fills Durham and west where 104.3 is clobbered by104.1 in Winston-Salem. Not too much overlap. I think format change eventually or a sale. Probably format change.
