WRC-07 and future HF spectrum usage

In the last quarter of 2007, more than 1000 representatives of 189 countries will gather for four weeks in Geneva at the International Telecommunications Union (ITU) World Radiocommunications Conference (WRC-07). One agenda item will focus participants´ attention on the future use of the HF radio spectrum between 4 and 10 MHz and the demands placed on it by a variety of services. After introducing the ITU this paper examines the agenda item and then focuses on various positions being advocated, many of which are mutually exclusive, and initiatives to solve this complicated issue.
