I find on all the radio's I use including my car radio, WLW's slop only spreads 10KHZ in either tuning direction, although it seems to be worse to the left of the dial. Bear in mind that I seldom travel north and to Mason where I presume WLW would spread two or three notches in either direction.
Especially on the west side where (I presume) urban sprall weakens WLW's signal, I can almost always hear WGN. I will also say that Chicago signals are weak, and infrequently they are not above the threshold.
We now return you to your regularly scheduled WBT thread already in progress.
