CQ Zone 39/Africa off-shore, Indian Ocean History of call sign allocation The call sign allocation history of mainland Africa and off-shore islands is complex and related to the colonial status of European powers in the early-20th century period. Call signs changed in relation to various independence movements, particularly following World War II and in the 1960s. International Radiotelegraph Conferences The conference held in 1927 assigned call prefixes to Morocco (CNA–CNZ), Egypt (SUA–SUZ), Republic of Liberia (ELA–ELZ), Ethiopia (ETA–ETZ), and the Union of South Africa (ZSA–ZUZ). These, however, did not necessarily include amateur radio operation. African areas administered politically by colonizing countries (i.e. Great Britain, Portugal, France, etc.) adopted call signs issued to those countries for colonial purposes. The 1947 Atlantic City ITU Conference reallocated call sign blocks to African countries and European colonies according to this table.
