As much as I'd love to see a CHR in Huntsville, I don't think 97.7 is the right signal for it. It's not strong enough to go against WZYP. I may anger a few by saying this but I think CC should consider flipping 100.3 The River to CHR. The station has been on a decline for some time now and continues to worsen. Either that, or Black Crow should consider changing Star 99.1 to CHR. They're recent revamp has improved the station some but not much, and surely probably not as much as they were hoping. Plus over the past several months they've sounded much like they did before the change instead of the new fresh Hot A/C sound they transitioned to. That'd be a GREAT choice for a CHR with a 100,000 watt powerhouse to take on another 100,000 watt WZYP in a CHR Top 40 war.
As for 97.7, I always thought classic country would be a good choice considering how impressive WQAH 105.7's numbers are in the Huntsville market and how WEAK of a signal they have. With 97.7 going classic country on a much superior signal in comparison, I'd bet you would see WQAH's numbers dwindle away.
