The DXCC, or DX_communication
Century Club, is an award of the American Radio Relay League
, given for contacting and engaging in two way communications by means of amateur radio
with other operators in 100 "entities" such as foreign countries. In the USA and its territories, an operator must be an ARRL member to receive the award.
Communication may be by voice, Morse code, or other modes, and separate awards are available for operating using specific modes or methods, such as using only amateur satellite links.
