History
DXSS began its operations in 1977. At that time, it was an affiliate of GMA Network. It aired an AOR format.

In 1995, GMA ended its partnership with SBN. Not long after, DXSS rebranded as Music Now and switched to an Adult Top 40 format.

In 2002, the station rebranded as Mom's Radio 97.9 with a music and talk format targeting the mothers and mother-to-be.

In 2010, it rebranded back as DXSS with limited broadcast time.

In November 2015, Mom's Radio returned on air, this time via satellite from Manila under the management of Makati-based Estima, Inc. On February 25, 2018, all Mom's Radio stations went off the air due to financial constraints.

In June 2022, the station returned on air after Y2H Broadcasting Network took over the entire operations and rebranded as XFM with a news and music format. It initially served as a relay station of Tagum City-based 100.7 FM.

On October 4, 2022, XFM Davao and XFM Tagum respectively swapped non-license assets. The former became an originating station, while the latter has been downgraded to a relay station of Davao.

XFM Davao completed its full migration to an originating station on October 19, 2022, when the station held a grand opening of its studios and offices at the SBN compound, along Broadcast Ave., Shrine Hills, Brgy. Matina Crossing.

In early-2023, Davao-based independent news media outlet Newsline Philippines began blocktiming the station's late night slot for their flagship web newscast Newsline Evening News.
