On the contrary, there's also markets and towns where only the EMF networks exist as a CCM station, but there are no regional networks serving that area. Kalispell MT has Your Network of Praise in addition to K-LOVE, but they are not a 24/7 CCM network. YNOP only airs Christian music at certain timeframes during the day, with a lot of teaching/preaching, Jay Sekulow, Adventures in Odyssey, etc. throughout the other timeslots. Meanwhile, Missoula has a full-power CCM station with SOS Radio out of Las Vegas, and most of their broadcast day is music.
On my road trip, if I listened to Christian music, it was from the local and regional networks - I much prefer them to the mega-conglomerate out of Nashville that just keeps buying high-quality secular FM stations to air satellite programming with one generic local TOH ID per hour. Which is why I donated to my local 'regional' network's fundraiser this week (Positive Life Radio in eastern WA).
I just wish these CCM networks would realize their older audience would enjoy the classics as well. As far as they know, DC Talk, Point of Grace, Steven Curtis Chapman and Amy Grant don't even exist as Christian artists/bands. Unless it's "Don't Lose Heart," SCC's latest single. But he has how many #1s again? Even I'd love to hear a classic here and there from the '80s or '90s.
