How can I fix this? I worked A15AA on March 25, 1990 and have his QSL card. My DXbase 2007 is showing "9A" in the PREFIX COLUMN for this QSO. It should be indicating "ABU AIL IS". And Abu Ail Is. does not appear in the PREFIX DROPDOWN LIST. Can't find A15 or Abu Ail in my prefix database. What's the cure? Can't figure out how to manage the deleted countries. Ron K3SEW
