ITU Zones - introduction
Contacts between amateur stations, located in different parts of the world, can be a basis for obtainment many awards or be used to classification in contests. For these purposes the World is divided in ITU Zones (called sometimes IARU Zones) as one of two main manners. Another is WAZ Zones dividing.
ITU Zones are based on a partition of whole surface the World for professional radio communication. For them is used the name “CIRAF Zones” – they are in most subdivided in quadrants.
For HAM targets that zones were most suited to country borders – but not completely. In some cases countries are dividing trough limits to 2 or more pieces.
There is no single entity administering this issue. Consequently, there are no uniform rules that describe this subject. Thus, each national association can be very flexibly apply the general guidelines and use rules deviate from use in other countries.
Please be aware that amateur zones in maritime areas, are not set out definite boundaries. Therefore, stations working from moving objects at sea or in the air, practically alone determine their zone.
In this website I drew up detailed maps and descriptions gathered all zones, based on the maximum coherent information from different sources.
I hope that these materials will help organize the theme of ITU Zones and will allow a more precise determination of the position of amateur stations. I wish you satisfaction in using my materials.
