Abstract: This report is a spectrum resource assessment of the 1605–2000 kHz band. It includes information on rules, regulations, allocations, technical standards, frequency assignments, system characteristics, and applicable compatibility analyses pertinent to the 1605–2000 kHz band. Major issues are discussed concerning changes in the allocation tables due to WARC–79 decisions. Parts of the 1605–2000 kHz band are in transition from radiolocation service use to broadcasting service use. Major problems in this band are the sharing among traveler's information stations, radiolocation, and broadcasting and the proliferation of the cordless telephone. This report analyzes the possibility of sharing broadcasting g and travelers' information stations and radiolocation, along with addressing the problems associated with cordless telephones.

Keywords: electromagnetic compatibility (EMC); 1605–2000 kHz; broadcasting service; cordless telephone; radiolocation service; radionavigation service
