DK - Denmark

Denmark is divided into 5 Regions We will consider part of Denmark also the Faroe Islands and the Greenland. A special status will be given to the Island of Bornholm (EU-030). It is part of HS Region, but in consideration of the distance from the mainland (it is between Poland and Sweden) we will consider it as an entity, the Municipality of Bornholm. Usually the QSL cards report the QTH Bornholm Island, anyway the Postal Codes start with 37. Of course you can use Wikipedia to detect the County. The island of Fyn is now part of Syddanmark, but counts for EURA-082 (Sjaelland-Lolland-Falster and Fyn) and NOT for EURA-084 (Jylland).
