Maybe I could have been clearer, Paul. Yes, KDFC's 89.9 satellite, KOSC, is in Angwin. As I wrote further up the page.their satellite, KOSC, licensed to angwin.. is on 89.9 as has been mentioned here before and I heard it in Wyoming
KXJZ is in Sacramento, Capital Public Radio's music station. It has a handful of satellite stations and translators in NorCal. KXJZ, the "mothership", is on 88.9. One of its satellites might be on 89.9 somewhere (e.g. Tahoe, Placerville, Truckee).
