the relay of GMA-7 Manila with the logo of GMA was covered by the logo of Citynet. In November 2005, the station became a repeater of DZOE 11, which served as the flagship for GMA's newly-secondary national network QTV (or Quality Television, later renamed to just Q). GMA had reached an agreement with its owner ZOE Broadcasting Network to allow GMA to handle programming for the station in exchange for providing upgraded facilities for the broadcaster and airing ZOE-produced programming in QTV's lineup. DWDB's UHF signal had the advantage of easier to receive in the southern areas of Metro Manila, especially in the metropolitan cities of Makati and Pasay. This practice was discontinued in 2007, as DWDB's channel number was vacated for use in trials of digital television. Digital broadcast In February 2013, GMA started its digital test broadcasts, simulcasting both GMA-7 and GMA News TV-11 using the Japanese ISDB-T digital TV platform using the channel's frequency. On May 15, 2019, GMA Network's digital test broadcasts used the same frequency as its digital feed, and it also started its initial digital test broadcast on UHF Channel 15 (479.143 MHz), which served as the main digital feed of GMA Network when this frequency reverted to analog broadcast, and continued its service for the remainder of the analog feed. Reversion to analog broadcast; GMA News TV (2019–2021) On April 24, 2019, ZOE Broadcasting Network and GMA/Citynet announced that their blocktime agreement would expire by the end of May 2019. This ended their day partnership and in turn, their blocktime lease on VHF Channel 11 after 14 years. ZOE Broadcasting Network was reported to simulcast Light TV 33 upon termination of the agreement, but ZOE had no official statement yet on its future plans, however the network became active again on June 22, 2020, after making a deal with new blocktime partner and erstwhile rival network ABS-CBN to open A2Z Channel 11. As a result, Channel 27 digital broadcast was planned to switch off on May 27, 2019, as the station was supposedly conducting its test broadcast on the said date. The channel in turn, was to be re-utilized to broadcast GMA News TV in analog by June 3, 2019, after 18 years of inactivity. However, GMA Network had to allot time for the digital television viewers to re-scan their digital boxes in order to continue watching their channels in a different frequency
