First off if this is just an April Fools prank the joke is on them...Beasley will be stuck with FRESH.
Finally I'll throw in a wild card and guess a totally different format they might switch to...News Talk KDWN-FM. FM Talk is a hot format to flip to right now. It's getting results too, the one FM talker that was underpreforming, KTLK/Minneapolis, had an excellent trend yesterday. Most of them do well right out of the gate with demos AM stations can only dream about.
I still think KXNT would have more potential on FM than KDWN would. The syndicated lineup on KDWN is not as strong, although I think Savage would do great on FM. Jerry Doyle might have potential too, he is #1 in Providence on an AM station. The weekend wall of infomercials KDWN plays would have to go (or stay on AM only).
