DXRU/DXGR (1188 AM & 103.9 FM) Radio Ultra and G103.9 Gold Radio is a radio station owned by Hypersonic Broadcasting Center and operated by Ultracraft Broadcasting Corporation. The station's studio is located at Suan Arcade, Masterson Ave., Brgy. Carmen, Cagayan de Oro, and its transmitter is located at Brgy. Taboc, Opol.
The frequency was formerly used by DXIF from December 30, 1987, to April 22, 2011, when it transferred to 729 kHz. On July 31, 2025, the station added the FM frequency 103.9 MHz and is currently conducting test broadcasts. 103.9 FM is rebranded as G103.9 Gold Radio.
This station was reported to Kabayan in DZMM on Sep, 2015 when 2 (technically 3) of itâÂÂs reporters got fired, because the staff and reporters ate a lechon with a note saying âÂÂTo Radio Ultraâ by the son of then city mayor, Oscar Moreno. The lechon was originally meant to be brought to the ownerâÂÂs house, Girlie Gualberto-Suan, for a dinner, but the technician panicked and said âÂÂNaubos na namin.âÂÂ, so the reporters and staff raised money and bought another lechon. Later, in March, 2016, the station lost the case.
