 The island has long been an attractive destination for amateur radio groups, due to its remoteness, the difficulty of landing, permit requirements, garish history, and interesting environment.While some radio operation was done ancillary to other expeditions, major DX-peditions include FO0XB (1978), FO0XX (1985), FO0CI (1992), FO0AAA (2000), and TX5C (2008).One DX-pedition was the Cordell Expedition in March 2013 using the callsign TX5K, organized and led by Robert Schmieder.
