Hate to say it but the mighty Frog will never be toppled by the format they have on 94.3 at the moment. To make a bigger splash I'd say they should flip-flop the oldies format from WKMC over to the FM side of things and put leave the country on the bird on AM and they may make an impact. Absolutely no one is listening to 94.3 Cricket or no Cricket. Froggy's just too big to stop.
radiocreeper: Your absolutely right, 94.3 isn't really making much of an impact whatsoever, i've been listening while Cricket is on, and honestly I think nobody even knows the station is there. Just the fact that Froggy has been around for 20 + years, and the brand identity of Froggy, everybody knows what it is, whether it sucks or not, its too big to kill and they aren't going to change no matter what true country tries to do.
Also your right about WKMC, it would be better to switch.
