Not exactly KUOW2 ending...just their broadcast on 91.7FM
Given the stipulations that the station must remain local when it was sold to PRC (Which means no K-Love, Calvary Chapel, etc...), I doubt it'll go religious. Northwest Public Radio already has KVTI, so I don't think they'd have interest in KXOT other than maybe for the pending move to Gold Mountain.
NWPR still has that NPR News/Talk channel......I wouldn't put it ENTIRELY past them. They've been dying to get that signal out in some major area of Western WA (Though I'm sure KUOW would raise hell over that. But obviously KUOW really doesn't have much room to bitch about it if they did...)
There's also KING-FM. Don't know about their finances, but being a new non-com player, it's another potential scenario.
There's a lot of local public and community stations in need of a bigger reaching signal. It's just the $$$ problem......
