Broadcasting on 101.3 MHz, XHMSL is owned by Luz Network and known as Stereo Uno with a pop format.
XHMSL broadcasts in HD Radio and carries three subchannels, Vintage (HD2), Siempre (HD3, changed from Luz before launch) and El Fuerte sister station XHPFRT-FM La Morrita (HD4).
Its current format is a variety of Spanish and English pop music, and also local news.
In 2015, RSN sold the station to a new group known as Luz Network as part of a family split.
Luz has since expanded the Stereo Uno brand to other cities in the state, with XHPNAS-FM in Navolato/Culiacán signing on in 2019 and XHZS-FM in Mazatlán being purchased the following year.
