KBOQ (B103.9) is a commercial soft adult contemporary radio station in Monterey, California, broadcasting to the Santa Cruz-Carmel-Salinas, California, area on 103.9 FM. K-Bach had been broadcasting on 95.5 FM until the format was moved to 103.9 on February 9, 2008, essentially putting an end to the Modern Rock/Hard Rock/Alternative/Hip Hop hybrid music format branded as "X103.9". The spot vacated by K-Bach's move has been filled by a country music format. On February 14, 2008, the call sign was changed to KKHK and then finally swapped with the KBOQ call sign on February 26, 2008. On October 17, 2011 KBOQ changed their format from classical to soft AC, branded as "B103.9".
