Founded by Mabuhay Broadcasting Systems, Inc. in 1972, DZXQ is a fully maintained station filled with blocktimers except for Sunday. It is the first AM station which aired Chinese Programming from 9pm - 12mn. The station also aired music programming when no blocktimers are on the air. Back then, it operated daily from 5 am to 12 midnight and its studios are at 17th floor of The Centerpoint Building, Julia Vargas Avenue, Ortigas Center, Pasig City. DZXQ was the home of Powerhouse Broadcasters such as Nar Pineda, Roger Arienda, Rolly Canon, Narissa Gonzalez, Ducky Paredes, Jhino Parrucho, Ruben Ilagan, Popo Villanueva, Roland Lumagbas, Dr. Erick San Juan and Reggie Vizmanos. It was also the home to An Affair with Baby Tsina, a lifestyle radio show. On February 28, 2011, DZXQ ceased operations, a few days after a new set of investors acquired the station, whose immediate plans are to close only for six months, but the plan was later shelved. Nar Pineda and the Powerhouse Broadcasters were forced to move to DWSS, while some moved to DWBL.
As DWUN (2011-present)
In late 2011, the group identified with radio executive and innovator Manuelito "Manny" Luzon, the man behind Love Radio while he was still with MBC embarked on a project to rehabilitate the fledging station. MBSI's airtime, formerly occupied by Energy FM, was occupied by Luzon's 91.5 Big Radio. Since November 2011, DZXQ's airtime on AM band was occupied by Breakthrough and Milestones Productions International, as content provider of news and public service programs, and began its test broadcast, airing UNTV simulcast feed. Other timeslots were mostly filled by religious content provided by Ang Dating Daan. The station eventually became a 24/7 radio station and its callsign was later on changed from DZXQ to DWUN. On January 16, 2012, the station was formally rebranded as Radio La Verdad 1350 kHz. Its mission is to bring back the glory of radio, from the current trend which is radio sans images or “Radio on TV”. In 2017, the UNTV Radio was rebranded to "Radyo La Verdad 1350" with a new logo and slogan "Totoong Balita, Tunay na Kalinga Para sa Kapwa".
Mobile radio booth
UNTV Radio also introduced a mobile radio booth, a first in Philippine Radio history, where it broadcast from a specific location via see thru mobile studio vehicle.
Outside of its broadcast coverage area, Radyo La Verdad programs can be accessed via live streaming by downloading the UNTV Mobile App through the Apple App Store for iOS devices and Google Play Store for Android devices for free.
Network rehabilitation
DZXQ's old and obsolete facilities such as faulty transmitter, antenna and power supply, dilapidated and poorly ventilated transmitter house, improvised "catwalk" made of bamboo, all in deplorable condition, resulted in weak signal reception even in nearby cities. MBSI AM radio facilities were gradually upgraded. A new transmitter house in Barrio Muzon in City of Malabon was constructed, new concrete "catwalk" going to the transmitter and installation of a new transmitter antenna. Further, the station's radio booths were also modernized. After four decades, Radyo La Verdad replaced its old analog tube-type 10-kW transmitter with its brand new 50kW solid-state radio transmitter, which has been in use since 2017.
