ITU Radiocommunication Sector

The ITU-R plays a vital role in the management of the radio-frequency spectrum and satellite orbits, finite natural resources which are increasingly in demand from a large number of services such as fixed, mobile, broadcasting, amateur, space research, meteorology, global positioning systems, environmental monitoring and, last but not least, those communication services that ensure safety of life at sea and in the skies.


ITU Radio Regulations Article 25:


Amateur services
(Updated by the decisions of the WRC-03)

25.9B  § 5B  An administration may determine whether or not to permit a person who has been granted a licence to operate an amateur station by another administration to operate an amateur station while that person is temporarily in its territory, subject to such conditions or restrictions it may impose. (WRC-03)

Section II. Amateur-Satellite Service

25.10   § 6.    The provisions of Section I of this Article shall apply equally, as appropriate, to the amateur-satellite service.
