XHWZ-FM has changed names more times than most listeners in San Luis Potosí can probably remember, but its current identity as La Mejor has stuck the longest, and it fits the region better than either of its predecessors ever did.
A Frequency With a Long History
According to Wikipedia's history of the station, the concession behind this signal dates back to May 8, 1979, when it launched as AM station XEWZ under owner Sergio Ramírez Hernández, broadcasting from the town of Cerritos. It later moved to Soledad de Graciano Sánchez with studios in San Luis Potosí proper, before making the jump to FM as XHWZ-FM 90.9 on June 7, 2012. The station spent its first year on FM as Radio Novedades, flipped to adult contemporary Más FM in September 2013 under operator MG Radio, and finally became La Mejor on December 3, 2016, once MG Radio aligned itself with the MVS Radio network.
Part of a National Grupera Network
La Mejor is MVS Radio's dedicated grupera and banda format, carried on affiliate stations across the country from Hermosillo to Acapulco, each running the same national brand with regional programming layered on top. For San Luis Potosí, that means a steady stream of grupera and banda hits alongside regional Mexican staples, positioning the station as the city's home for the genre rather than a one-off local outlet.
Broadcasting Into Huapango Country
San Luis Potosí sits at the edge of the Huasteca region, a cultural zone spanning parts of Tamaulipas, Hidalgo, Querétaro, Puebla, and Veracruz that gave rise to the huapango, a musical tradition built around a trio of jarana huasteca, Huastec violin, and quinta huapanguera, with dancers keeping rhythm through intricate footwork known as zapateado. The tradition runs deep enough that huapango was formally declared part of the state's Intangible Cultural Heritage in 2011, and communities across the region still hold annual Huasteca festivals built around huapango competitions, according to regional music historians at Música en México. La Mejor's grupera format is a different genre entirely, but it broadcasts into an audience whose musical identity was shaped by that older folk tradition long before banda and grupera arrived.
Why It's Worth Tuning In
La Mejor San Luis Potosí offers a direct line into the grupera and banda sound that dominates regional Mexican radio today, broadcast from a city whose musical roots run back centuries further, into the huapango trios of the Huasteca.
