DWBM-FM

Mareco Broadcasting Network, Inc., owned by Villar family[1] led by Manuel Sr.,[2] made its debut in the radio industry in 1963.

[12] Upon the declaration of nationwide martial law in 1972, a decree was issued ordering a broadcast company to operate an AM and an FM station in each area.

[3][4][18][19] In 1994, when Luis Villar sold the shares to his children, the station went to his son, Louie, who reformatted it as Crossover.

[1][5][21] They also produced live concerts by foreign artists, jazz performers Bobby Caldwell and Phil Perry,[25] David Benoit, Basia, and The Spinners.

At the same time, the station had its first two disc jockeys after almost a decade, April Padil (formerly from NU 107) who boarded during weekday mornings and Benjamin (Reuben "Beng" Chua, formerly of Dream FM and Citylite who is a former voiceover of PTV/NBN from 1998 to 2011 and AksyonTV from 2013 to 2019; he currently serves as the voiceover of RPTV since 2024), also boarded during weekday evenings.

On December 30, 2019, 105.1 FM silently dropped its Crossover brand and smooth jazz format and switched to a Top 40 format, as MBN opted to lease the station's airtime to Horizon of the Sun Communications (producer of Chinese Filipino oriented shows Chinatown TV and Chinese News TV).

The station announced on the following day that the Crossover FM format has migrated online (via its live stream application).

On March 1, 2020, former Monster Radio jock and chief digital strategist Lexy Angeles took over management of the station.

In the same month, the station launched new shows: Q Eclectic, a Saturday evening show that featured predominantly OPM, K-pop, C-pop, and Latin Pop, Q Mix, a Saturday late night program that played music remixes, and Sunday Flashback, an all-day segment which aired 2000s music.

On June 19, 2023, Q Radio announced that the station will permanently go off the air due to financial problems, as well as poor ratings and loss of advertisers' support.

This includes the transfer of Brigada News FM National's operations from its former frequency assignment at 104.7 MHz, based in Batangas.
