History
1995–2013: K91/City Lite/Smooth FM
The station was established in 1995 as K91. It had an Adult Top 40 format. In 1998, it became an affiliate of Raven Broadcasting Corporation in Manila and rebranded as City Lite 91.5 with a smooth jazz format. In early 2000, after it ended its affiliation with RBC, it rebranded as Smooth FM 91.5. It went off the air sometime in 2013.
2015–2024: Brigada News FM
In early 2015, Brigada Mass Media Corporation took over the station's operations and became part of the Brigada News FM network. The station's old transmitter was replaced with a new 10,000 watt transmitter bought from Quark Electronics of Italy. Regular programming was first aired on August 10, 2015. In time for the 30th Kadayawan Festival, on August 23, 2015, Brigada News FM was formally launched. Then Davao City Mayor (now Vice President) Inday Sara Duterte, Brigada Group of Companies President Elmer Catulpos, and other Brigada officials were present in the occasion.
On January 2024, Mareco-owned 93.1 FM begin simulcasting this station as part of transition with the latter frequency to be launched this April 15.
On March 17, 2024, after Brigada News FM Davao shifted its full-time operations to 93.1 FM, this frequency is downgraded to a repeater of the latter with limited broadcast hours (signing off every 10:00 am) until Brigada will abandon this frequency on April 15, 2024, in preparation for Memories FM or PCMC's Favorite Music Radio which is rumored to be launched the near future.
