XHMMO-FM is a radio station on 105.1 FM in Hermosillo, Sonora, Mexico.
It was owned by María de Lourdes Palacios Andrade, but Radio S.A. began to operate the new station nearly immediately.
In 1993, the group launched “FM 105.1 5 – 5 Canciones Continuas”, a format emphasizing playlists of five songs in a row.
On February 3, 2023, the station changed its format to regional Mexican, relaunching as La Raza 105.1 FM.
However, XHMMO has been mired in the same labor problems affecting Radio S.A., including expired concessions, low pay, several strikes, as well as technical problems with FM transmitters.
