May I suggest that even though you're finding alternatives to the problem that it can't hurt to drop the Reds a letter and complain. They need to hear from fans when things like this happen. They clearly can't afford to lose a big market like Louisville.
Sometimes I think it's the bane of the powerful signal of WLW. Few folks know the link to their local station carrying the game. I remember being in Chillicothe and asking someone what station broadcasts the Reds - "oh, 700". Well if it was cloudy or something, you weren't going to pick up the game.
BTW, the Reds website still shows the station as WKRD-AM 790.
