KSAN (FM)

KUFY/KVEZ

On April 1, 1963, KUFY signed on with a beautiful music format that targeted San Jose and the South Bay area. The call letters would change to KVEZ in 1968.

KSOL

In the 1970s, an Urban/R&B station operated on 107.7 and was known as KSOL (K-Soul). Originally broadcast on 1450 AM (now KEST), KSOL moved to the FM position in the early '70s, making it the first urban contemporary radio station on the FM dial in the San Francisco Bay Area. Sly Stone played a part in influencing the station to the point where it was a successful radio station in the region. While KSOL managed to fend off competition from KBLX unscathed throughout the 1980s, the station's ratings began to decline due to competition from KMEL, then a Top 40 station which was slowly evolving in a rhythmic-turned-mainstream urban direction. Eventually, the decision was made to end KSOL 107.7 and its format. The DJs were notified beforehand and held a goodbye show to send off KSOL on February 10, 1992. The final song on KSOL was "Miss You Much" by Janet Jackson. Afterwards, KSOL segued into a 72-hour loop of "Wild Thing" by Tone Lōc.

KYLD

On February 13, 1992, at 3 p.m., 107.7 FM flipped to Rhythmic Contemporary, branded as "WiLD 107." The first song on "WiLD" was "D.M.S.R" by Prince.^[1] For the first year and a half, the station retained the old KSOL call letters. Allen Shaw's Crescent Communications bought the station in December 1993 and changed KSOL's call letters to KYLD the following year. They also purchased 99.1 in San Jose from Viacom, and began simulcasting 107.7's programming in the South Bay, in order to help fill 107.7's signal limitations. Program Director Rick Thomas and Music Director Michael Martin were the original team that set a plan in motion that was the beginning of the end for the then dominant KMEL. They came with a strategy of playing "old school" and up tempo freestyle/dance songs like those heard on heritage San Jose radio station HOT 97.7. KMEL finally settled in on the urban contemporary format at the same time, and that station and KYLD battled with each other throughout the mid-1990s.

KSAN

At 12:01 a.m. on July 2, 1997, KYLD moved to 94.9 FM. 107.7 and 94.9 would simulcast until Midnight on July 7, when 107.7 FM, now with the KSAN call letters, began stunting with construction noises and song clips as a prelude to a flip to classic rock at Noon on July 11.^[2]

On March 13, 2000, at 3 p.m., after playing "Goodbye Yellow Brick Road" by Elton John, the station relaunched as "The Bone," playing classic rock with a harder edge. To initiate this change, the station played AC/DC "A to Z," all 154 songs by the band to that date in alphabetical order.^[3]
