## History

XEWA received its concession on December 2, 1948, one of a string of repeaters of [XEW-AM](/source/XEW-AM) 900 Mexico City authorized in the late 1940s. XEWA began operations on the frequency of 540 kHz with 150,000 watts of power — still its current levels, making it the most powerful AM radio station in the country.

In May 1961, a second **XEWA-AM** was licensed to operate in [Monterrey](/source/Monterrey), [Nuevo León](/source/Nuevo_Le%C3%B3n), in order to provide daytime XEW service and an improved nighttime signal there. It operates with 1,500 watts during the day and 1,000 watts night.

On March 16, 1988, XEWA struck out on its own with a [grupera](/source/Grupera) format known as Súper Estelar WA. Broadcasting from Monterrey, Súper Estelar was programmed by [Multimedios Estrellas de Oro](/source/Multimedios_Radio) and served as one of Mexico's pioneering grupera stations. After five years, Súper Estelar left XEWA and migrated to [XHSNP-FM](/source/XHSNP-FM) 93.7 (later 97.7) in San Luis Potosí, which was owned directly by Multimedios; it was also carried on some Multimedios radio stations in other cities until the format became known as La Caliente.

The end of Súper Estelar made way for a flip to the Ke Buena format from [Radiópolis](/source/Radi%C3%B3polis), which lasted until 1998 when the station began repeating XEW again, now known as "Cadena W Azul y Plata" and later as "W Radio". In 2003, [Radiorama](/source/Grupo_Radiorama) began managing the station for Televisa Radio.

In July 2009, saw the first ever split between XEWA Monterrey and XEWA San Luis Potosí. The San Luis Potosí station was transferred to local radio company MG Radio, while XEWA Monterrey began offering a Nuevo León-specific version of W Radio; ever since, XEWA Monterrey, now on FM as [XHWAG-FM](/source/XHWAG-FM), has been a separately programmed station which is currently operated directly by Televisa Radio.

In San Luis, XHEWA-FM 103.9 was authorized in 2011 and came on the air that July; while it is technically an AM-FM migrant, the AM station cannot be shut off until radio service is available in the entirety of its coverage area, including ten municipalities in five states with no other radio service.[5] In 2012, Radiorama returned to manage XEWA/XHEWA, and in July, W Radio was replaced with [Los 40](/source/Los_40) Principales. Radiorama's regional affiliate in Tampico, Grupo AS, took over the San Luis Potosí region in 2016 and operated it until December 31 of that year. On January 9, 2017, GlobalMedia, which also had begun programming Ke Buena in San Luis Potosí on [XHBM-FM](/source/XHBM-FM) 105.7, took over operations of XHEWA after the station spent several days directly relaying [XEX-FM](/source/XEX-FM) Mexico City.
