History

DXUM was launched in 1957, 8 years after Atty. Guillermo Torres launched DXMC and the same year UMBN was founded. While DXMC broadcasts news and variety programming, DXUM airs music programming.
During the Martial Law era, the ownership and licensee of DXUM was transferred to Mt. Apo Broadcasting System of the Mt. Apo Science Foundation, another institution also owned by Torres and is a sister association to the UM.
In November 1978, due to the switch of the Philippine AM dial from the NARBA-mandated 10 kHz spacing to the 9 kHz rule implemented by the Geneva Frequency Plan of 1975, the station's frequency was transferred to 936 kHz.
During the 1970s and the 1980s, DXUM was the top music station in Davao City.
In 1988, two years after EDSA People Power Revolution, the disc jockeys of DXUM were transferred to DXMC, which was converted into the FM band and became known as Wild FM. Following the changes in the landscape of AM radio now dominated by rival stations, DXUM transferred to its present frequency and reformatted as a news/talk station under the brand Radyo Magasin. After a few years, it rebranded as Radyo Peryodiko, and then Radyo Balita. From 2000 to June 15, 2020, the Radyo Ukay branding was used.
