The BS7H Scarborough ReefDXpedition was an amateur radio expedition that took place April 29, 2007 – May 6, 2007. It was cut short at the request of the Chinese government.[5] The trip to the reef was authorized by the Chinese Ministry of Foreign Affairs and the State Sports Commission.[6] The team of 17 people came from 7 different countries and worked in 8-hour shifts manning the radio stations and would return to their vessel to recover and rest.[5][1] To operate the team had to build four wooden structures on the rocks that would prevent them from being overtaken during high tide.[7] At the time of the event Scarborough Reef was one the rarest locations for radio operators to contact and was a notable highlight for many operators who were able to make contact.[8]
