-- The profile already stores the station callsign (callsign — what's
-- transmitted) and the operator callsign (operator — who is actually
-- working the radio). Some setups need a third: owner_callsign, the
-- legal owner of the station. This matters at a club station or a
-- remote setup where the operator and owner aren't the same person.
-- ADIF maps this to STATION_OWNER.
ALTER TABLE station_profiles ADD COLUMN owner_callsign TEXT NOT NULL DEFAULT '';
