In May 1961, a second XEWA-AM was licensed to operate in Monterrey, Nuevo León, in order to provide daytime XEW service and an improved nighttime signal there.

Broadcasting from Monterrey, Súper Estelar was programmed by Multimedios Estrellas de Oro and served as one of Mexico's pioneering grupera stations.

The end of Súper Estelar made way for a flip to the Ke Buena format from Radiópolis, which lasted into the late 1990s when the station began repeating XEW again, now known as "Cadena W Azul y Plata" and later as "W Radio".

On January 9, 2017, GlobalMedia, which also had begun programming Ke Buena in San Luis Potosí on XHBM-FM, took over operations of XHEWA after the station spent several days directly relaying XEX-FM Mexico City.

XEWA-AM is the dominant clear-channel station at 540 AM, powered at 150 kilowatts to cover the Mexican states of San Luis Potosí, Nuevo León, Tamaulipas, Coahuila, Zacatecas, Querétaro, Guanajuato and Aguascalientes.
