KSLX-FM is a Classic rock radio station serving the Phoenix, Arizona area. The Hubbard Broadcasting, Inc. outlet broadcasts at 100.7 MHz with an ERP of 100 kW and is licensed to Scottsdale, Arizona. KSLX simulcasts in digital HD Radio. Its studios are located on North 52nd Street west of Papago Park and its transmitter is in South Mountain Park.


From its sign-on on August 1, 1969 to April 1, 1978, this station was known as KDOT-FM, "K-Dot," and programmed the "beautiful music" format. The studios were on the second floor of a building adjacent to the Safari Resort hotel, on Scottsdale Road just north of Camelback Road in Scottsdale, Arizona. Every hour at the top of the hour the station would give the Legal ID announcement: "From the beautiful Safari Resort, this is K-D-O-T, Scottsdale." Just before midnight on the evening of April 28, 1978, the station broadcast its last selection from the beautiful music format. After a short pause, a new call sign was announced on the air, KOPA, and a format switch to Top 40 began. The first song broadcast on KOPA was "Hello, Goodbye" by The Beatles. The call sign KOPA was pronounced "copa" and reflected the last two syllables of Maricopa County (home to Scottsdale and the greater Phoenix metropolitan area). Original KOPA Program Director was Steve Rivers and Music Director, Brian Christian.

The station operated as KOPA until February 5, 1986, when the station call signs, owners and format were changed again. Standard Communications purchased the radio station and renamed it KSLX-FM which would later reflect on sister stations KPLX Dallas, KBLX Berkeley and KFLX Flagstaff. KSLX hosted a popular morning program in the late 1980s, the "Jones and Boze Show", featuring David K. Jones and Bob Boze Bell. Bell is a popular local western artist and writer (and co-owner and Executive Editor of True West Magazine since 1999). The station would later be acquired by Sandusky as a sister station to KDKB and KUPD, thus creating a rock cluster in the market.

In 2017 KSLX ascended to the top of the Phoenix ratings for the first time in its 31 year history. The station now plays Led Zeppelin, the Eagles, Def Leppard, AC/DC, Journey, the Beatles, Pat Benatar, the Rolling Stones and more. The on-air line-up is Mark and Neanderpaul from 5-10am weekdays, followed by Randi Scott 10am-2pm, Pete Cummings hosts 2-7pm, Russ Egan is on 7pm-11pm with the syndicated Alice Cooper Nights Show from 11pm-1am.
