93.1 KKHR / Los Angeles

Format Change: Mellow Rock KNX-FM Los Angeles flips to CHR as HitRadio 93 | August 25, 1983

Perhaps the most coveted aircheck on this site from Los Angeles is this format change of 93.1 FM from ‘Mellow Rock’ KNX-FM to “HitRadio 93” KKHR. Your webmaster’s experience with CBS Radio’s ‘Mellow Rock’ format is from Boston, where 103.3 WEEI-FM was Boston’s “Soft Rock”. In that case, WEEI-FM took a month to do a gradual change from Soft Rock to Top 40, then eventually a tighter CHR as WHTT (Today’s WODS).

In Los Angeles, this abrupt flip to CHR was immediately preceeded by a tastefully done history of Mellow Rock KNX-FM’s format and jingles. It marked the end of a ten year period where the ‘Mellow Rock’ format grew and flourished.

This aircheck marks the end of probably the most stable and best remembered period in 93.1’s history. The start of the HitRadio 93 format will evoke another emotion. This aircheck is about one third KNX-FM and two thirds HitRadio.

One other interesting tidbit – The KKHR call letters that were identified with HitRadio 93 were not yet authorized by the FCC, so when HitRadio launches with Todd Parker at 3:00 PM, the first legal ID is for HitRadio 93, KNX-FM Los Angeles. In Boston, HitRadio 103 began its life as WEEI-FM and later became WHTT. I guess in the corporate world, new trends tend to roll out in similar fashion at different offices, it’s mostly no different in radio.

  1. KNX made me so happy….a good part of my life…I could always listen to the music and feel great….such a huge loss in my life when it went off the air. 101.9 KSCA here in LA was also a great station….till it sold out. Barbra Streisand and Neil Diamond were never played on KNX….the station has influenced my musical taste to this day….The Bridge on Serius is very similar…..

  2. KNX was mainly mellow rock until around 1982, when it began experimenting just a little bit with some more eclectic material. At that time, KNX broke all the molds. I remember hearing little-known songs by the likes of Duran Duran, Tears for Fears and Mental As Anything. It was done so well that they were able to integrate it seamlessly with their softer offerings. When the announcement came over the airwaves that they were changing over to a “Hit Radio” format, my stomach dropped. I was at work, and I was practically in tears. So many important memories were tied to KNX-fm. I’ve never found anything like it since.

  3. Actually They Were 3 HitRadios In The ’80’s, WHTT HitRadio 103 In Boston, KKHR HitRadio 93 In Los Angeles, And The 1 That Started It All KHTR HitRadio 103 In St. Louis.

  4. OK guys. Check on Facebook. There is a KNX-FM page. About halfway down are 26 minutes and 37 seconds of KNX-FM Jingles. Perfect quality too. Enjoy

  5. I started a KNX-FM tribute facebook page. Check it out at // Lots of interesting trivia, pictures,jingles, etc!

  6. Having lived throughout California and the east coast,
    I have never found a station that compares or comes
    close to KNX-FM. Now residing in Hawaii… Rick

  7. It was great that 93.1 LA changed from a too soft Elevator music format to an upbeat CHR format and the first song on the CHR format was by a local Los Angeles recording artist, Michael Jackson. KNX-FM had very low ratings and Hitradio 93 was needed to keep ratings afloat. CHR is an awesome format and is much better than that Mellow Rock.

  8. Oh, the stories I could tell, but I won’t. My Ex worked there from the late 70’s until the switch-over, and then he worked for CBS-AM downstairs.

  9. James it neat that you mention Dave Hall. He and Michael Sheehy were my mentors at KNX-FM circa 1980, when I was an intern. I learned invaluable programming lessons from those two. KNX FM and AM launched my career.
