100.1 W Radio (San Luis Potosí)

100.1 W Radio (XHPM-FM) is a radio station on 100.1 FM in the city of San Luis Potosí, San Luis Potosí, Mexico. It is owned by GlobalMedia and affiliated with W Radio, carrying talk programming.

XHPM signed on on August 1, 1977, though it received its concession a year later, on August 25, 1978. It was owned by MVS Radio founder Joaquín Vargas Gómez and carried MVS's Stereorey format for 25 years. In 1990, XHPM was sold to Centro de Frecuencia Modulada. On September 2, 2002, Stereorey was replaced nationwide with Best FM, offering a newer music mix; XHPM was the last Best FM station until, like most others, it converted to the La Mejor grupera format on March 12, 2007.

In late 2009, an alliance between local company Controladora de Medios and MVS created GlobalMedia. On November 2, 2009, GlobalMedia restored the Stereorey name and format—the only city where this happened. On January 9, 2012, XHPM kept the format but changed its name to FM Globo, and on June 1 it took on the unique "Hundred FM" name.

On January 16, 2017, XHPM changed its name to "WFM" and picked up W Radio talk programs. The station fully branded as W Radio in May 2020.
