I'm on another forum that has been discussing this station for many months. It's been interfering with KBOO. The shoulders of this analog signal on 90.5 overlap with the licensed signal on 90.7. It's also blocking out a licensed low power FM signal on 90.3.
It's Radio Faro de Luz, and they were running a Spanish language religious format.
The church is currently abandoned and owned by another church in Salem, Oregon. As the landowner, the church in Salem is being threatened with the fine.
