A limited number of stations are licensed with call signs that do not
indicate DXCC country. These include those authorized by the United Nations
and the World Meteorological Organization. One year I worked four stations
with the same prefix in the WPX contest -- "4U1" -- and each was in a
different DXCC entity. The logging programs generally get them right, and
the contest sponsor software always has them right for final scoring.
