schmave said:The example of WKNR disappearing around McConnelsville is a textbook example of southeast Ohio's ground conductivity eating up otherwise excellent AM signals. WKNR has an only slightly weaker signal in central Ohio than WLW daytime, and it seems the only place they tuck in their signal is to the east (dramatically) to protect a co-channel in Pennsylvania.
I can vouch for that, I attend Kent State University, which is almost directly in their SE null, their daytime signal is very weak, and their nighttime signal is practically nonexistent. I usually hear KOA stronger. It's kind of aggravating, since WKNR is basically the only sports station in the area with decent local programming.
