IOTA Challenge: Work all the XX-001 Islands
I enjoy island chasing and especially the RSGB's Islands on the Air (IOTA) program.
The QSL cards from the islands are often very nice. I use and like LOTW for electronic confirmations, but I almost always send off for a paper QSL too.
I wondered what it would take to work the first designated island in the IOTA designated geographic areas.
IOTA entities are organized into seven broad categories based on geography:
Africa: AF-xxx. AF-001, 3B6, Agalega Islands
Antarctica: AN-xxx. AN-001, Various prefixes, Graham Land West (Adelaid Island)
Asia: AS-xxx. AS-001, VU, Andaman Islands
Europe: EU-xxx. EU-001, SV5, Dodecanese
NA: NA-xxx. NA-001, C6 Great Bahamas Bank group
Oceania: OC-xxx, VK, Australia (Main Island Only)
South America: SA-xxx. SA-001, CE0, Easter Island
xxx= specific island designation
I think most would agree, at least for continental USA staions, that NA-001, OC-001 and SA-001 would be the easiest to work. I admit I have a West Coast bias on this.
EU-001 is harder to work but there seem to be stations to work although I do not have it confirmed for IOTA. I have worked it via remote station in CT but this can not, because of CT distance from my home QTH, can not be used in the IOTA program.
AF-001 and AS-001 are more challenging in that their are fewer stations to contact. My impression is that AF-001 3B6 Agalega Islands and AS-001 VU Andaman Islands are mostly served by expeditions and are relatively rare. Nevertheless I have had heard these such stations over the last couple years. I do not have either confirmed for IOTA though.
AN-001 is probably the most difficult to work because of the location and sparsity of stations. Not to mention the DX pileups such places create!
The specifics on AN-001 are:
AN-001 Various Prefixes ( 66º35–68º30S, 066º00–070º00W)
======================================
d.GRAHAM LAND WEST (ADELAIDE ISLAND) group (=Adelaide [Rothera Base VP8], Amiot Isls, Detaille, Horseshoe, Kirkwood Isls, Leonie Isls [include Anchorage, Lagoon, Leonie], Liard, Stonington
I've concluded that the working all seven of the XX-001 IOTA island groups would be quite a challenge but would take some time given that DX expeditions or research stations would provide the best--or only--opportunity for two to three of the necessary QSOs.
