KNX-FM (97.1 MHz, "KNX News 97.1 FM") is a commercial radio station in Los Angeles, California, United States.

The station has studios at the intersection of Wilshire and Hauser Boulevards in the Miracle Mile district of Los Angeles, and the transmitter on Mount Wilson.

In addition to a standard analog transmission, KNX-FM broadcasts in the HD Radio format and streams online via Audacy.

During the July 8, 1972, edition of American Top 40, Casey Kasem listed KGBS as the show's affiliate in Los Angeles.

[citation needed] On July 31, 1979, Storer, after having sold the AM radio station which was now known as KTNQ (Ten-Q), moved its top-40 format to 97.1 FM and began broadcasting as KHTZ ("K-Hits").

To demonstrate the vastness of the station's on-air library, KLSX advertised "no-repeat workdays", not playing any song more than once per day.

An exception was when the station played one song twice as part of a contest; listeners could win a prize for being the destination caller and identify correctly the intentionally repeated track.

Whenever the station played "Southern Man" by Neil Young and Crazy Horse, it was always followed by Lynyrd Skynyrd's "Sweet Home Alabama".

[citation needed] On July 31, 1995, KLSX changed to a hot talk format on weekdays and went by the moniker "Real Radio 97.1", and had hosts such as Susan Olsen and Ken Ober, Scott Ferrall, Riki Rachtman, Kato Kaelin, Mother Love, Carlos Oscar, Voxx, Tim Conway Jr., Doug Steckler and the Regular Guys (Larry Wachs and Eric von Haessler).

During that era and prior to being sold, KLSX boasted the only late-night talk shows in Los Angeles featuring women as hosts: Dr. X and subsequently a short-run of Shrink Rap.

On October 25, it was announced that Adam Carolla would take over as the station's morning show host in January 2006 due to Howard Stern's departure to satellite radio.

In 2008, he was given his own (local) one-hour show following Frosty, Heidi and Frank, in a timeslot that had been vacant since the departure of entertainment reporter Sam Rubin in 2003.

On February 17, information started to emerge that KLSX was to drop hot talk on February 20 and flip to a top 40 format aimed at younger listeners, taking the "AMP" format that was created by KROQ-FM program director Kevin Weatherly and APD John Michael on the HD2 channel of KCBS-FM.

[citation needed] The launch of "AMP" marked the first top 40 radio battle in Los Angeles since KPWR switched to a hip hop-heavy rhythmic contemporary format in 1994.

On January 4, 2010, KAMP-FM rounded out their on-air lineup, which featured Carson Daly in mornings, Chris Booker middays, Ted Stryker afternoons, and Casey McCabe at night.

[22] On August 3, 2020, The Morning Mess from Phoenix sister station KALV-FM, hosted by Joey Boy, Aneesh Ratan, Jeana Shepherd, and Karla Hernandez, began broadcasting on KAMP-FM.

The change took place at 3 p.m. that day, dropping the "Now" format about 30 seconds into playing "Sunflower" by Post Malone and Swae Lee.

[25] On December 21, 2021, KNOU changed its call letters to KNX-FM, further reflecting the AM station's primary signal shift to the FM band, while still being heard on the existing 1070 AM frequency.

This marked the return to the Los Angeles airwaves for the KNX-FM call sign, last used on March 2, 1989; 35 years ago (1989-03-02).

[27][28] On August 31, 2018, KNX-HD2 dropped Pulse 87 to make room for the newly launched "Out Now Radio", a talk/EDM format targeted to the LGBTQ community.
