History

XHZS received its concession on August 25, 1987.

The station has had various formats, including Los 40 Principales and the Planeta format.

In May 2016, XHZS flipped from Radiorama to MegaRadio affiliation and consequently changed names from @FM to Switch, as the former is a Radiorama-specific brand.^[3] The station reversed the change in 2017.

In March 2020, Luz Network assumed ownership and operation of the station and began programming its Stereo Uno pop format; this gives Luz Network a presence in all three major Sinaloa cities, as it owns stations in Los Mochis and Navolato–Culiacán. The Federal Telecommunications Institute approved XHZS-FM to begin broadcasting in HD Radio in 2022.^[4]
