KPMO

1300 AM KPMO has been on the air in Mendocino, California since 1979.  "Billy Ball" refers to the aggressive style of play encouraged by the Oakland A's Billy Martin when he was manager the baseball club in the early 1980s.  KPMO is owned by Southern Oregon University and is part of the Jefferson Public Radio network of stations headquartered at KSOR in Ashland, OR.  Early 1980s Broadcasting Yearbooks list KPMO's formats variously as Beautiful Music, Country & Western and Talk.  It's unclear when they were sold and went from a commercial to a non-commercial outlet.
