KSOQ was previously assigned the call letters KFSD while owned by the Astor Broadcast Group, who chose a format of classical music acquired from Lotus Communications in 1997, which in 2001 switched to an alternative rock format as Premium 92/1, still with the KFSD call letters.

In 2003, KFSD-FM was purchased by Jefferson Pilot Communications and turned into the simulcasting partner for their popular KSON, which faced geographical challenges to its signal's penetration into the North County area of San Diego County as well as into southern Riverside County, problems largely solved by the addition of KSOQ.
