Islands on the Air (IOTA) Unique Identifiers

Islands on the Air IOTA Logo

Islands on the Air or more often just refereed to as ‘IOTA‘ are very often sort after, these can range from the very largest of all our Islands to the smallest Reef in the world and can be completely uninhabited except for the wildlife that makes these small bits of rock home.

For that reason, we seek these out and when a group of amateurs strike out on what we term as a DXpedition to these remote spots in the world, we often see some major pile-ups on the bands with many stations trying to conform their contact to the remote places on our planet.
