Amateur radio or ham radio call signs are unique identifiers for licensed operators in Antarctica. Call signs are regulated internationally by the ITU as well as nationally by governing bodies within each country who may have nationals operating in Antarctica. Call signs may also be issued by a local Antarctic authority (i.e. base commander) who chooses from a block reserved by their national body for that purpose. The Antarctic Treaty signed on December 1, 1959 (and entered into force on June 23, 1961), established the legal framework for the management of Antarctica, including allocation of amateur call signs.
The Video is a tribute to all those who have worked on HAM Radio in the white continent:
Although Antarctica is considered international by treaty, amateur radio operators in Antarctica are often subject to the reciprocal licensing requirements pertaining to the country under which the camp is flagged.
The Worldwide Antarctic Program keeps a list of special event call signs issued from various countries at various times. TM4IPY was issued in 2007 by France to celebrate the International Polar Year as was IAØIPY, IA8IPY, IA7IPY & IP7IPY by Italy, GB4IPY by The United Kingdom, VYØICE/VE2 in Canada, LZØ7IPY in Argentina, EV5IPY in Belarus, CQ4IPY in Portugal, SNØIPY in Poland, YE2IPY in Indonesia, S5ØIPY in Slovenia, 5DØIPY in Morocco, and others. These callsigns were used by amateurs in their home countries.
