Classification and Designation of Emissions

A new, much more complex, but needed, system of designating emissions has been agreed and incorporated into the Final Acts of WARC-79. Its use will be mandatory for frequency registration with the International Frequency Registration Board (IFRB) after January 1, 1982. Full designation is with nine alphanumeric characters in two parts; four characters for necessary bandwidth followed by five symbols for emission classification. Of the five classification symbols, three are mandatory and are found in the lists of Article 4. The last two symbols, which are optional for use, may be taken from lists in Appendix 6. WARC-79 made provision for expanding the choices of the optional symbols to give future flexibility as technology develops. The complete method for designating emissions is contained in this paper.
