KDEY-FM (93.5 MHz, "93.5 KDAY") is a commercial radio station that is licensed to Ontario, California, and serves the Inland Empire area.

Media Management Company, Inc., bought the station from receivership in 1976; Jato Communications acquired it in 1978, changing the call letters to KNTF.

Former staff members of KRZE include Steve Craig (later at WRXP in New York), Kevin Barrett (who became program director at KTRB "XTRA Sports" in San Francisco), and Lisa Osborne (news anchor at KFI).

After three years of simulcasting, Magic announced that KDAY would get a signal upgrade and cover more of the Los Angeles area as an urban contemporary/urban talk outlet.

[9] In May 2014, KDEY-FM and KDAY were sold to Meruelo Group, which also owned Los Angeles television station KWHY-TV (channel 22).

Previously, the show aired on KHHT until February 2015, when that station dropped its rhythmic oldies format in favor of urban contemporary as KRRL.

However, on March 1, KDEY-FM flipped to R&B/hip-hop as "Wild 93.5", giving the Inland Empire its first urban outlet since 1994, when KAEV dropped the format for modern rock as KCXX.

KDEY-FM retained its urban format and continued focusing on the Riverside-San Bernardino market until its return to simulcasting KDAY on October 30, 2017, to avoid direct competition with its newly-acquired sister station as Meruelo management saw KDEY's urban format as redundant, despite having researched targeting the area and to address signal coverage and overlapping issues.
