This signal was created in 1981 when then owner Marcos Rodriguez Sr. successfully petitioned the FCC to change the frequency of KESS 93.9 to 94.1 and permit a move to the Cedar Hill, Texas antenna farm. His son, Marcos A. Rodriguez, controlled this frequency from 1986 to 1999.
In 1964, Marcos Rodriguez Sr. was hired by Mike Bradley and became the first full-time employee of 93.9 (then owned by John Walton and called KBUY-FM). John Walton purchased KBUY when it was called KCUL. Its call letters came from the backwards spelling of the original owner's name - Dr. L.H. Luck.
Sometime in early 2014, KLNO (alongside other Univision-owned stations) has dropped its "La Que Buena" branding in favor of using the frequency as its name. This was done until 2016 when it returned to its branding.
