-- MY_IOTA: the island reference the station operates FROM, e.g. "EU-005".
--
-- An official ADIF field, and the QSO table has carried my_iota since 0001 —
-- only the station profile could not supply it, so an island activation had to
-- have the reference typed on every contact or added afterwards. Blank by
-- default: the overwhelming majority of stations are not on an island.
