HI K69 is an unused radio station found in Fort Carson in Grand Theft Auto: San Andreas.
Marvin Trill, the mysterious host of the conspiracy radio show Area 53 is thought to broadcast from this building. During the shows, Trill claims to be speaking from a "trailer in the desert", but may still rely on the building for his broadcasts. In one episode of Area 53, Trill sarcastically asks another caller if they can "destroy the other radio stations in town", implying that he has some links to a radio facility in the desert. Myth hunters have scouted around the premises for any signs of Trill, such as a possible physical encounter with him, or to witness the Domestobots in the desert mentioned on his show. No actual unique pedestrian activity will occur around the station, however.
All radio stations in the western United States have a station identifier beginning with K, and this is reflected in the other in-game stations K-DST and K-JAH, so the building has also been proposed as a planned or scrapped radio station. Its name is somewhat generic and does not indicate what kind of music would be played, whereas at least one other removed radio station in the game has a more apparent name: Dopealicious FM.
The tower has also been blamed for sudden radio interference and mysterious phone calls, though the nearby vast radar complex of The Big Ear remains the most commonly reported origin and most plausible cause of these disturbances.
The building is one of the many locations in the game jokingly named after the 69 sex position.
