KAMA (AM)

The station signed on the air on July 11, 1985.^[4] It served as a relocation of KAMA, which had been at 1060 AM and it aired a Spanish-language format with a heritage stretching to Juárez's XELO-AM. The move to 750 allowed KAMA to broadcast around the clock. (The 1060 frequency had been for daytime use only due to a more powerful station on 1060 in Mexico City. A new El Paso station was later created at 1060, KFNA although that is now dark.)

In 1994, KAMA 750 was sold to Tichenor Media, operator of longtime rival Spanish-language station KBNA. Tichenor merged into Heftel Broadcasting in 1997, changed its name to Hispanic Broadcasting Corp. in 2000.

In 2003, Hispanic Broadcasting Corp. merged into Univision Communications. Univision is a large owner of Spanish-language television and radio stations across the U.S.

For a time, beginning in 2012, KAMA was the El Paso outlet for the national Univision America talk network.^[5] That programming later moved to sister station KQBU at 920 AM.

In 2016, Univision Radio exited El Paso radio market. It sold its stations to affiliates of Mexican radio broadcaster Grupo Radio Centro for $2 million, with GRC taking over operations via local marketing agreement (LMA) on November 8.^[6] Rafael Márquez, a United States citizen, owns 75 percent of the licensee, 97.5 Licensee TX, LLC, with the remainder being owned by Grupo Radio Centro TX, LLC.

On November 1, 2022, Pro Radio LLC took over the local programming and marketing agreement from Grupo Radio Centro TX. In December 2024, 97.5 Licensee TX, LLC, entered into an LMA with Big Bend Broadcasting for an FM translator. It took control of K224FC at 92.7 MHz and began to simulcast the programming on KAMA 750 AM.

On January 3, 2025, KAMA 750 AM and 92.7 FM started broadcasting a new format, combining syndicated hot talk programs with Spanish-language hot adult contemporary music.
