The history of 100.9 FM in Mexico City begins with Televideo, S.A., receiving a concession for XEOY-FM in 1957. However, the station didn't sign on the air until April 18, 1968; 58 years ago (1968年04月18日). The original call sign was XEBS-FM, using the moniker "La Chica Musical". In the mid-1970s, the station became known as "Sonomil" (a name derived both from its position at 100.9 FM and from XEOY-AM 1000). This name was referred to in the station's call letters when it became XHSON-FM in 1978.

The format moved toward album rock in 1983 and 1984. The station took the name "Proyecto 101" on September 1, 1983 and then Rock 101 on June 1, 1984. The call sign changed to XHROK-FM in 1994.

In August 1996, due to low ratings and changes within Núcleo Radio Mil, management decided to flip formats. It became "Código 100.9" with techno EDM music. The call sign returned to XHSON-FM.

On January 8, 1999, the Sabrosita tropical music format moved to 100.9 FM from XEPH-AM 590. The tropical format moved back to AM on September 20, 2004, at which time 100.9 FM returned to the EDM format on October 1.
