DWIZ (882 kHz AM) is a 24-hour commercial news/talk broadcast radio station serving the Mega Manila market. The station is owned and operated by Aliw Broadcasting Corporation, a subsidiary of the ALC Group of Companies. The station's studio is located at the 5th Floor, Citystate Centre, 709 Shaw Boulevard, Brgy. Oranbo, Pasig City, while its transmitter is located at Osmeña St., Brgy. Pag-Asa, Obando, Bulacan. DWIZ operates 24 hours daily, except Maundy Thursday to Black Saturday annually.
At present, DWIZ 882 is considered as one of the top stations in the AM band in Metro Manila and is recognized as the best AM radio station in the Philippines by the Kapisanan ng mga Brodkaster ng Pilipinas or KBP. Using Tagalog as its medium, it brings much needed information and entertainment to its listeners all over the Philippines and neighboring Asian countries, targeting the upper four economic classes. True to its slogan, "Ang Himpilang Mas Todong Lakas", DWIZ 882 gives crisp and crystal clear sound which can be heard nationwide, powered by 50,000 watts stereo transmitter, through its relay RPN Radyo Ronda stations (selected programs only) and through online streaming services. DWIZ is currently headed by Ely Aligora as the station manager.
Early beginnings as DZPI, the first iteration of DWIZ (1949-1991)
It was then known as DZPI from 1949 to 1972, broadcasting at 800 kHz until November 1978 when it transferred to 882 kHz due to the adoption of the 9 kHz spacing for medium wave stations as stipulated by the Geneva Frequency Plan of 1975 (aka GE75) supplanting the NARBA mandated 10 kHz spacing rule. DWIZ officially started its broadcast operations on September 24, 1972 as DWIZ Sunshine City, owned and operated by Manila Broadcasting Company's affiliate, Philippine Broadcasting Corporation (and it was one of the stations established during the Martial Law for the first time, which dated 3 days from the issuance of the Proclamation No. 1081 (and it was formally announced the day after at that time). It was then a music formatted station from 1972 to 1986, when it shifted to a full service format with emphasis on news and music, that lasted until 1991, when Aliw Broadcasting Corporation, a radio network under the leadership of former Ambassador & Chairman Emeritus of the ALC Group of Companies, Mr. Antonio Cabangon Chua acquired the station. DWIZ 882 Sunshine City signed-off for the last time on the first quarter of 1991 after almost three decades of broadcasting under the MBC banner.
The current iteration of DWIZ (1991-present)
Upon acquisition, test broadcasts of the 25,000 watt-powered newly formatted AM station started during April 1991, and it successfully lasted for a month. The station also pioneered another first in the history, as it introduced the Broadcast Tandem System, wherein each news program has two broadcasters on board. Leading the station's first years of broadcast are some of the anchors and reporters transferred from DZRH (one of them is Rey Langit, who eventually became the station manager in 1991, until he resigned in 2016). The first big news coverage on DWIZ was the country’s annual Independence Day celebrations in 1991, followed immediately by the eruption of Mount Pinatubo. In 1994, DWIZ officially switched to its current 50,000 watt transmitter facility.
In 2000, DWIZ relocated their studio from Dominga Building, Pasong Tamo, Makati City (home of Aliw's sister companies BusinessMirror and Pilipino Mirror) to their current home in Citystate Centre in Shaw Boulevard, Pasig.
On January 3, 2014, DWIZ signed a 3-year memorandum of agreement with Radio Philippines Network (owner of CNN Philippines-affiliated stations and Radyo Ronda) for the expanded coverage of the both TV and radio networks nationwide. Selected programs of this station are also simulcasted on the Radyo Ronda Network. DWIZ also launched its first ever radio jingle on July 14, 2014 during the onslaught of Typhoon Glenda (Rammasun).
In 2016, DWIZ officially relaunched its newly upgraded 50,000 watt transmitter system standing on a 300-foot tower, providing improved signal reception in the Greater Luzon Area.
The year 2014 and 2015 served as milestone for the station as it received several recognitions:
