Well, I'm glad to see we're at least playing 3D chess now. haha. This is kinda the main question. Where are there more listeners to potentially steal? My oversized gut tells me that WTDY shares listeners with more stations than does WXTU. If that's true, going after the WTDY audience means going after a smaller and more fractured audience. That would make me think it's better to go after WXTU's listeners. But there's also the consideration of how gettable these audiences are. If there's more available Country listeners but they're less likely to be fickle (meaning they aren't likely to tune away from 92.5), then ya got a problem with your new Country station.
All this having been said, I am not wavering on my opinion that Country is going to land at 106.1. And after having said that, I also wouldn't be the least bit surprised if whatever ends up happening, whenever it ends up happening, involves the 104.5 frequency as well--which would obviously be something even beyond 3D chess. (Somewhere around here, someone asked "What are the chances that a company would mess with more than one of their stations at the same time?" and it's like, "Ummmm, it happens all the time!")
