Many thanks to SWLing Post contributor Richard Cuff, who shares the following news via the Philippine News Agency:
The government’s international service, Radyo Pilipinas World Service (RPWS), is set to resume shortwave broadcasts on 1 December 2025 from the Philippines Transmitting Station in Tinang, Tarlac. The relaunch comes through a new partnership between the Presidential Broadcast Service–Bureau of Broadcast Services and the Commission on Filipinos Overseas (CFO), which aims to create a global network of volunteer correspondents reporting from Filipino diaspora communities. These broadcasts underscore shortwave radio’s continued value in connecting remote and global audiences—including overseas Filipino workers—with cultural news, heritage programming and first-hand reports from abroad.

to answer my own question, apparently there was an agreement signed in 1963{!} that gave the US control over that site. the equipment is ancient but possibly could be replaced.
This is what they say on their website: “Radyo Pilipinas World Service uses the relay transmitter facilities of Voice of America in Tinang, Concepcion, Tarlac for its broadcast purposes.”
Why did it need US AGM approval?
Are the frequencies and times known yet?
This is their old schedule. Maybe try some of these frequencies.
Language Time (UTC) Frequencies (Shortwave)
Filipino Service 17:30 – 19:30 9.925 MHz, 12.120 MHz, 15.190 MHz
English Service 02:00 – 03:30 9.475 MHz, 15.640 MHz, 17.820 MHz
Thanks a lot
