The KFSD call sign was on 600 from 1926–1963. KFSD was also on FM 94.1 from 1948 to 1963, then re-appeared on 94.1 in 1973 until 1997. The KFSD-TV call sign was on Channel 10 from 1953–1963. The three KFSD stations switched to the KOGO call sign in 1963, as information about San Diego and its people were fed into a new IBM computer and asked for the perfect call letters for these stations, and it chose KOGO. The last iteration of KFSD-FM 94.1 was as a classical station. KFSD had a good solid audience, but the station was bought by Nationwide Communications (division of Nationwide Insurance). Nationwide felt a change to more aggressive music was a better choice for the only 100 kW station in San Diego. KFSD was changed to KXGL, and became the Eagle 94.1. The Eagle's format proved to be a failure, and in 1998 became KJQY/KJOY 94.1.
