DZSR (918 AM), on-air as Radyo Pilipinas Dos (RP2) or RP2 Sports, is a radio station owned and operated by the Presidential Broadcast Service, an attached agency under the Presidential Communications Office. The station's studio is located at the 4th floor, Media Center Building, Visayas Avenue, Barangay Vasra, Diliman, Quezon City, and its transmitter is located at Malolos, Bulacan. DZSR operates daily from 5:00 AM to 8:00 PM or until 10 pm, during PBA game days.
As the country's first radio station dedicated to sports, Radyo Pilipinas 2's programming grid is 70% sports content and 30% news, informative, and lifestyle programming carried over from DZRM Radyo Magasin. On September 18, 2017, Sports Radio was rebranded as Radyo Pilipinas 2, merging its programming with Radyo Magasin (now Radyo Pilipinas 3-Alert).
It is also the home of the radio coverage of the Philippine Basketball Association.
200px|thumb|left|Sports Radio logo (1996–2017)DZSR was formerly known as DPI Radyo Maynila during martial law. On May 10, 1986, Sports Radio (first known as DZSR SportsCenter 738) was established under the leadership of former actor Jose Mari Gonzales who took over as the Interim Director of the Bureau of Broadcast Services (former name of PBS). Gonzales ordered that all BBS radio station will give their respective identities including Radyo ng Bayan (918 kHz), Radyo Maynila (1278 kHz, now Radyo Pilipinas 3-Alerts) and DZRP-Radyo Pagasa. DZFM was converted at that time as a news and information station covering sports developments in the country.
Before DZFM was rebranded as Sports Radio, it was then-known as Radio Sports, which is just a segment of the government radio station DZFM. Reynaldo "Dado" Roa was the first station manager, and at the time, the first staff of DZFM was composed of sports writers and reporters from the Radio Sports department and radio newscasters of the said station. DZFM, later renamed their call letters to DZSR on 738 kHz, however the station's callsign was reverted to DZFM as a courtesy to the original owner of the frequency, Frederick Marquardt, an American national who donated the 738 kHz frequency to the Philippine government.[1]
On January 2, 1995, Sports Radio's frequency was moved from 738 kHz (now occupied by Radyo ng Bayan) to 918 kHz and changed their call letters back to DZSR under Memorandum Order No. 329. (Presidential Order No. 293)[1] On March 1, 1996, 5 years after Marquardt's death, and later to Cesar Soriano and his placed by the broadcast.
On February 1, 2010, it changed its callsign to DWSY (wherein the "SY" means Sports & Youth), as they expanded their programming from sports-related shows to youth-oriented programs. The youth programs of DWSY named "Youth Service" usually air on Saturdays. At the end of 2010, its call letters reverted back to DZSR.[2]
On September 18, 2017, Sports Radio was rebranded as Radyo Pilipinas 2, merging its programming with Radyo Magasin, which was shut down the previous day. The latter's former frequency was revived in 2020 as a DepEd TV simulcast and became Radyo Pilipinas 3 (RP3 Alert) in 2023.[3]
In March 2020, Radyo Pilipinas 2 temporarily went off-the-air amid the community quarantine imposed in Metro Manila due to COVID-19.
On March 7, 2022, Radyo Pilipinas 2 returned on air.
In January 2023, Radyo Pilipinas 2 acquired the rights to cover the Philippine Basketball Association on air. It is also simulcast on with selected Radyo Pilipinas provincial stations.
