The station began its broadcasting activities under Freedom Network's direction in 1986 with a Southern Gospel format the temporary call sign KLCA before making a permanent switch to KDFT two months later.
Then in 1990, the station was sold to Way Broadcasting, and changed its format to urban gospel, focusing on Dallas-Fort Worth's African American community. From that day on, it was known as "The Rainbow Across North Texas" (the station's slogan).
Change to Spanish
In 1998, KDFT again changed its format to SpanishChristian radio format under the same name and slogan until 1999. In 2000, Radio Unica purchased KDFT from Way Broadcasting. Then in 2004, its current owners Multicultural Broadcasting absorbed KDFT and the remainder of Radio Unica's stations after that company filed for bankruptcy a year prior.
Throughout the station's existence, it has operated as a daytimer, required to sign off at night. But in 2004, it received Federal Communications Commission permission to expand its airtime to 24 hours a day.
