For forty years radio astronomers have had access to frequency bands allocated by the International Telecommunication Union (ITU) - initially a League of Nations body (from 1919) and then a United Nations body (since 1945). Hard work and skilful negotiation by a handful of radio astronomers since 1959 have ensured viable access to scarce spectral allocations. There have been many battles won, some key battles lost. The next treaty conference of the ITU is in the year 2000.

AbstractThe radio spectrum is a finite and increasingly precious resource for astronomical research, as well as for other spectrum users. Keeping the frequency bands used for radio astronomy as free as possible of unwanted Radio Frequency Interference (RFI) is crucial. The aim of spectrum management, one of the tools used towards achieving this goal, includes setting regulatory limits on RFI levels emitted by other spectrum users into the radio astronomy frequency bands. This involves discussions with regulatory bodies and other spectrum users at several levels – national, regional and worldwide. The global framework for spectrum management is set by the Radio Regulations of the International Telecommunication Union, which has defined that interference is detrimental to radio astronomy if it increases the uncertainty of a measurement by 10%. The Radio Regulations are revised every three to four years, a process in which four organisations representing the interests of the radio astronomical community in matters of spectrum management (IUCAF, CORF, CRAF and RAFCAP) participate actively. The current interests and activities of these four organisations range from preserving what has been achieved through regulatory measures, to looking far into the future of high frequency use and giant radio telescope use.

The annual report of the International Telecommunication Union (ITU) to the Economic and Social Council for the year 1953 stated that considerable progress had been made by the various countries during the year in developing or modernizing existing telecommunication networks, within the limits of technical and scientific progress and of credit available for investment in communications. The grid of telegraph and telephone circuits criss-crossing frontiers had been considerably tightened up and reinforced during 1953, important research work had been carried on, certain practical steps had been taken with a view to providing the public with semi-automatic international telephone service and a direct international telegraph subscribers' service, and the national broadcasting networks and television transmittal services had been expanded and improved. While the credit for these achievements, the report stated, was above all due to the specialists, no extension of telecommunication networks would have been possible without the intervention of the organs of ITU in the coordination of projects and in organizing cooperation between the various countries. The report contained information on ITU membership and on the organization and operation of the permanent organs of ITU, as well as a detailed summary of ITU activities during the year 1953, its relations with the United Nations and other international organizations, and its budgets for 1953 and 1954, for which the overall figures were respectively 6,225,100 and 6,367,500 Swiss francs, exclusive of United Nations technical assistance funds.
