EMF operates slightly different. They rarely have K-LOVE on in markets where there is an existing Non-Commercial CCM station. They don't want to compete with other non profits for the same exact listeners. If they end up getting a signal in one of those markets, they put Air1 on them. Air1 targets a younger audience. College students and Millennials love their Contemporary Worship music these days. If you look at KHRI in Hollister, they have numerous translators attached to it. A lot of them were put in cities where there is a college nearby. They used to reach out to that age group with harder edged Christian Rock and Pop (Which has pretty much disappeared it seems)
They will put K-LOVE on the air in areas where the CCM station is commercial. That doesn't automatically mean their programming is better (They are extremely safe musically compared to a lot of others, since they are national) It's no surprise The Fish is doing well in Atlanta with local programming. The difference is K-LOVE isn't competing with them for advertising revenue.
When they buy a stronger signal in a market where K-LOVE is already on the air, they put K-LOVE on the stronger signal and add Air1 to the previous frequency.
As far as EAS goes, they run these stations by the book. Really good engineering. For Public Affairs, 7PM Pacific on Sunday Evenings they have a national show "Closer Look" which is followed by a local segment in many markets. They do have some local and regional studios and promotions teams. They also have a lot of local outreach and listeners can literally call them on the phone 24/7 and talk to a live person. Even when there is no jock on the air overnights, there is someone who will pick up the phone. They have a "Care Team" of pastors who people can call, speak with, pray with, all that. They can also give people information for a local area. They'll send you a Bible if you need one. It's a lot more than it seems, for some of these listeners it means a lot.
It's unfortunate that they buy out all of these signals, but they operate those signals at high standards. They don't let the transmitters rot. They're monitoring them 24/7. They take care of their employees. They take care of their listeners. Something a lot of other companies could learn from.
