XERC-AM is a radio station based in Mexico City on 790 kHz, currently silent. The station is owned by Grupo Radio Centro.
History
In 1946, Francisco Aguirre Jiménez created XERC-AM under the concessionaire Radio Popular de México, and originally being branded as "Radio Continental". This station would serve as the base for what would become Grupo Radio Centro, as "Radio Éxitos 790" and sister to 1030 AM XEQR-AM, known as "Radio Centro 1030".
In the 1960s it became "La Campeona 7-90", a subname/slogan of "Radio Éxitos", a pioneer in broadcasting Spanish-language rock, but mostly airing then-current music in English from all genres. Its famed Beatles Club program, which began in 1964, remained on the station for 25 years and later moved to FM on "Universal" (XEQR-FM until December 4, 1998, XHFO-FM until May 13, 2016, XHRED-FM until October 30, 2019 and since June 1, 2020, and XERC-FM between October 31, 2019 and May 29, 2020), where it still airs to this day. It was a strong competitor to Nucleo Radio Mil's XEPH-AM ("La Pantera") and Grupo ACIR's XEL-AM ("Radio Capital") for younger audiences who listened to the latest music in English.
On September 12, 1988, 790 AM was relaunched as "Expresión 7-90", a spoken format.
