Registration Board, the International Radio Consultative Committee, and the International Telegraph and Telephone Consultative Committee.~/ RADIO REGULATIONS (GENEVA, 1979) The Radio Regulations complement the International Telecommunications Convention. The most recent edition was done in Geneva in 1979 and is considered generally applicable although some members of the ITU have neither informed the Secretary-General of the ITU of their appr0val, nor become party to an International Telecommunications Convention since the entry into force of the Geneva Radio Regulations (a second method of indicating acceptance of the Radio Regulations). The Radio Regulations (Geneva, 1979) have been modified by World Administrative Radio Conferences. However, many members have not yet informed the Secretary-General of the ITU of their approval of these revisions. The United States asswnes obligations to the Radio Regulations and any modifications thereto only upon completion of its domestic process and its subsequent notification of acceptance to the Secretary-General of the ITU. International Telecommunications Conventions require members of the ITU to abide by the provisions of the Radio Regulations (see, for example, article 44 of the Nairobi Convention). Generally, the Radio Regulations establish a world-wide frequency allocation scheme, and provide for a system of international co-operation through the notification, co-ordination and registration of radio stations. Satellites, whether domestic or international, conform to the provisions of the Radio Regulations (except for those satellites exempted by article 38 of the Nairobi Convention and predecessor provisions). Considerable resources are expended by ITU members in the co-ordinationprocess to eliminate harmful interference in the use of the radio frequency spectrum. TELEGRAPH AND TELEPHONE ~EGULATIONS (GENEVA, 1973) These two sets of regulations, like the Radio Regulations, complement the International Telecommunications Convention. ITU members assume obligations with respect to them through the operation of the Convention which includes a provision for members to notify their approval of any revision. The Telegraph
