AX, ANTARCTICA (Special Callsign). Bob, VK0BP, currently employed by the
Australian Antarctic Division as a Communications Tech from Davis Base
Station (WABA VK-03, WAP AUS-03, IOTA AN-016), Antarctica, will be using
the special callsign AX0BP on April 25th, to celebrate ANZAC Day. ANZAC
Day is a national public holiday to commemorated and honor the members
of the Australian and New Zealand Army Corps (ANZAC) who fought at
Gallipoli in Turkey during World War I. This holiday is observed by
Australia and New Zealand, as well as the Cook Islands, Niue, Samoa and
Tonga. Bob can only use this callsign from midnight to midnight (local
time -- Davis is +7 hrs UTC). However, Bob will not be able to operate
the full 24 hours but will do his very best to operate as long as possible
that day. Australian operators can only use the AX prefix just 3 times
per year -- Australia Day (January 26th), ANZAC Day (April 25th) and
World Telecommunications Day (May 17th). QSL via VK2CA, direct only
(2 USDs and a SAE is preferred).
