Study Group 6, propagation in ionized media

During the 4-year plenary cycle which has just concluded, Study Group 6 has continued with its task of providing up-to-date and relevant information concerning propagation in ionized media, and radio noise. The emphasis continues to be on the provision of documentation for system planning, operation and design. The study group is organised into six working groups and this structure has provided, over a period of 12 years, a framework for the development of Recommendations and Reports in readily identifiable topic areas which have been reflected in the section headings within Volume VI of the CCIR proceedings (Dubrovnik, 1986). There has been a considerable imbalance in the workload in the Working Groups due to the priorities for study within Administrations and Agencies, but this has been accommodated without difficulty by the provision of a suitable distribution of meeting time
