DZRM 1278 (AM)
The station was launched in 1987 as Radyo Maynila (the brand was previously used at 918 kHz during the Marcos regime prior to EDSA Revolution) under the helm of former actor and BBS-PBS interim director Jose Mari Gonzales. Gonzales ordered that all BBS radio station will give their respective identities including Radyo ng Bayan (918 kHz), Sports Radio (738 kHz) and DZRP-Radyo Pagasa.
In the late-1996/early 2004, the station was reformatted as a cultural-oriented station under the name Radyo Magasin.
On September 17, 2017, Radyo Magasin finally went dark for the last time, after almost 20 years of broadcasting. Its programming merged with DZSR's programming on Radyo Pilipinas Dos, which was launched the next day. The defunct station's audio streaming space, meanwhile, was then converted to DWFO's audio portal on November 1 after it started a series of test broadcasts. It was planned to be rebranded as Radyo Pilipinas 3, but turned out to be for the shortwave service counterpart (which was initially planned to be rebranded as Radyo Pilipinas 4).
In October 2020, PBS resumed the broadcast operations of DZRM. The following week, however, began airing the audio simulcast of the DepEd TV programming as part of the country's distance learning initiative amid the COVID-19 pandemic.
