The station also aired a Rock format under the callsign KRIX and slogan "99X" in the 1980s. The station aired a Rhythmic CHR format as KRGY "Energy 99.5" beginning 1991-02-08 under previous owner Sunburst Media. On 1992-09-01, the station changed its call sign to KVSE then again on 1992-12-28 to the current KKPS. In 2011 KKPS dropped most of the Tejano music content from the 1990s, thus becoming more of a Regional Mexican radio station than just a Tejano radio station. With the change of the content, it gave the Rio Grande Valley area two Regional Mexican radio stations (including KGBT-FM, and excluding the Mexican radio stations that have the Regional Mexican format, such as XHAAA-FM in Reynosa, Mexico). In late 2012 the station changed their name from "Que Pasa 99.5" (Spanish for What's Up 99.5) to "La Nueva 99.5" (Spanish for The New 99.5). However, with the name change, the station kept the current callsign letters "KKPS".
