KXEN 1010 is a St. Louis station that has always baffled the hell out of me. 50KW daytime, yet 500 @ night? When I lived in St. Louis I found it to be pretty spotty (ground conductivity in parts of the metro really, really sucks.) I had mentioned it in a post a few years ago (a LOT of stuff has gone on since then.) Looking at a R-L map, it would seem like it shoots RIGHT down I-44. I would think that the ground conductivity down that way would absolutely kill it. Just like driving west from STL to Columbia listening to KMOX, you lose it before Columbia (the engine noise and blinkers were just killing it.)
