DZRB (738AM), broadcasting asRadyo Pilipinas - Radyo Publiko, is a radio station owned and operated by thePresidential Broadcast Service, an attached agency under thePresidential Communications Office. It serves as the flagship station of theRadyo Pilipinas network. The station's studios are located at the 4/F,PIA/Media Center Building, Visayas Ave., Brgy. Vasra, Diliman,Quezon City, and its transmitter is located at Brgy. Marulas,Valenzuela City. The station operates on Weekdays from 4:00 AM to 10:00 PM, and Weekends from 6:00 AM to 10:00 PM.
Established on May 8, 1933, DZRB is the first radio station in the Philippines before the launch ofDZRH.
On May 8, 1933, theInsular Government under theUnited States of America established and operated radio station KZSO in the Philippines, with a frequency of 710 kilohertz and power of 10,000 watts through theUnited States Information Service. In 1944, the callsign was change to KZFM, named afterFrederickMarquardt.[1]
In September 1946, two months after the Philippines gained independence from the United States, KZFM was turned over to the nascent Philippine government, and the Philippine Broadcasting Service was born.[2]
The station was first operated by theDepartment of Foreign Affairs until it was transferred to the Radio Broadcasting Board (RBB) created byPresidentManuel Quezon on September 3, 1937. In the same year, an international telecommunications conference inAtlantic City,New Jersey, assigned the letter "D" to replace "K" as the initial call letter for all radio stations in the Philippines. In January 1942, the RBB was abolished to give way to the establishment of the Philippine Information Council (PIC) which then assumed the function of the RBB, including the operation of DZFM. In turn, the PIC was abolished on July 1, 1952, and since then, until the creation of the Department of Public Information (DPI) in 1959, DZFM and the Philippine Broadcasting Service (PBS) had been operated under the Office of the President.[3]

DuringMartial Law, the Bureau of Broadcasts took over the station and becameDPI Radio 1 / MPI Radio 1. 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 theGeneva Frequency Plan of 1975, the station's frequency was transferred from 710 kHz to 918 kHz.[4]
In 1986 (after theEDSA Revolution), DZFM returned to its ownership by the establishment of the Bureau of Broadcast Services via the reinstated PBS.
The station would later be reformatted asSports Radio (the predecessor of Radyo Pilipinas 2).
On January 2, 1995, Presidential Order No. 293 ordered the transfer of Sports Radio to918 kHz, which led to the birth of the government's flagship station:Radyo ng Bayan (People's Radio) and it also transferred to 738 kHz frequency.[5]
During his firstState of the Nation Address, then-PresidentRodrigo Duterte announced he would support a law merging PBS with its TV counterpart,People's Television Network, into the "People's Broadcasting Corporation (PBC)".[6]
PBS announced that Radyo ng Bayan & its provincial AM stations will undergo a major rebranding, merging with the "Radyo Pilipinas" brand by June 5, 2017.[7] It was followed by the launching of Radyo Pilipinas Dos 918 kHz on September 18, 2017. Radyo Pilipinas's overseas counterpart (DZRP), which originally used the brand since the 1990s, remained on air but added "Worldwide" to avert confusion.
On May 5, 2018, Radyo Pilipinas' "TeleRadyo"-formatted video streaming channel began its simulcast overPeople's Television Network (PTV) nationwide and also streamed live via PTV's official Facebook account, with programs such asCabinet Report sa TeleRadyo (airing every Friday) andTutok Erwin Tulfo (airing from Mondays to Fridays). However, a few weeks later, both programs were cancelled in favor of infomercial programming as a preparation for the launch of Chinese TV programs on PTV until it was eventually cancelled in 2019. However, its TeleRadyo Channel resumed on September 13, 2023, replacingSalaam TV on PTV digital subchannel.
Under the new PBS Director-General Fernando "Dindo" Amparo Sanga, since September 2024, Radyo Pilipinas has rebranded its sub-brand asRadyo Pilipinas - Radyo Publiko on December 31, 2024 (New Year's Eve). Minor schedule changes and the launching of new programs began on January 6, 2025.
From February 17, 2025, its sister station104.3 The Capital began simulcasting selected news programming from Radyo Pilipinas - Radyo Publiko.
As the government's flagship radio station, it serves as a medium of development communication, a conduit between the government and the people, aiming to mobilize all sectors of society towards development and nationalism; the station features live, up-to-the-minute government news, live coverages of press conferences, as well as relevant information from different government sectors.
To better manage public information, a law should be passed, I'm addressing to Congress, to create the People's Broadcasting Corporation, replacing PTV-4, the government-run TV station, which now aims to replicate international government broadcasting networks.
