AM670 came on the air as KWNK in 1984, owned by Valley Radio LLC. The license was as a result of the FCC changing the Clear Channel Rules in 1982, which permitted the establishment of lower power radio stations on the clear channel frequencies. KWNK at 670 AM was allocated this frequency after protracted hearings by the FCC. Valley Radio's Consulting Engineer was Cecil Lynch who was one of the most respected engineers in the United States. KWNK served the Simi Valley and Conejo Valleys of Ventura County with 1 KW of power 24 hours. Eventually the FCC permitted Valley Radio to increase power to 5 KW Daytime and 3 KW Nighttime.
KWNK started as a Top 40 station as 'Top Hits 67 K.Wink', with music from Prince, Duran Duran, etc... A couple of notable program directors during that period were Jim Conlee (former PD of TenQ/KTNQ, Los Angeles), and Steve Smith. During the summer of 1986, KWNK slowly became more of an AC station, playing music from the likes of Amy Grant, due to direct competition from Top 40 KIIS AM.
Eventually, some of the talk shows that were on Sunday nights, moved full-time.
Then became a sports talk station in the mid-1990s, first carrying One-on-One Sports (now Sporting News Radio), then simulcasting the signal of "XTRA Sports 690" of the Tijuana-San Diego area. In 2001, AM690 ended the simulcast and KWNK then aired brokered-time programs for a brief period before it became "Radio Iran." It is the first, and as of 2013, only Persian-language broadcasting radio station in the US.
