About this reference: These are community-used 11-metre DX identifiers, not official amateur-radio callsigns, licences or proof of transmission rights. Some entries are historical, deleted, disputed or represent islands, radio entities and special locations rather than sovereign countries. Names and numbering follow established DX group conventions; club lists can vary. The PDF and this page include the historical entries for logging older contacts.
