History

In 1946, Francisco Aguirre Jiménez created XERC-AM under the concessionaire Radio Popular de México. 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 1998, XHFO-FM until 2016, XHRED-FM until 2019 and currently XERC-FM), 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. On October 21, 1990, the station flipped to an oldies Spanish music format as "El Fonógrafo" (The Phonograph). In October 2001, XERC and 1150 AM, then XECMQ (now XEJP-AM) switched formats: El Fonógrafo moved up to 1150 AM, and Formato 21, an all-news format consisting of a 21-minute news wheel that originated in 1993 on 1320 AM, moved down to 790.

In 2017, citing "changes in AM transmission infrastructure", Grupo Radio Centro reorganized all of its AM radio stations, shutting down several and consolidating their programs. Formato 21's news wheel moved to XERED-AM 1110. XERC then went silent.

On June 21, 2019, the Federal Telecommunications Institute authorized GRC to relocate XERC-AM to the transmitter site of XEB-AM, owned by the Instituto Mexicano de la Radio.[2] The IFT had authorized an identical change in 2017,[3] which expired in 2018 without being completed.[4]

gollark: Except you're using it wrong, and it probably slows you a lot, and most stuff should support AES or it's broken, and it's not been updated since july.
gollark: Yes, that is also bad.
gollark: Then you should use a faster encryption library, and also go to a company which allows you to remove technical debt.
gollark: In that case I'd say you're doing it wrong. You can send a random bit of data, stick it in an associative array or whatever stupid thing it's called mapping it to whatever this secret is, and then API 2 can take the random data, and find the secret in that associative array.
gollark: Look, if the client can't read the data anyway, *you can just send and store random junk*.
