Representatives of International Amateur Radio Union (IARU) member-societies in Europe are advising restraint in the wake of a proposal to consider the allocation of 146 – 148 MHz to the Aeronautical Mobile Service (AMS) at World Radiocommunication Conference 2023 (WRC-23). France recently raised the prospect during a European Conference of Postal and Telecommunications Administrations (CEPT) meeting in Prague, held in advance of WRC-19. A WRC-19 agenda item would call for studying a range of frequencies for AMS applications, including 144 – 146 MHz, and a decision could be made at WRC-23.
The French draft resolution seeks studies of possible new AMS primary allocations in several bands in the range from 144 MHz to 22.2 GHz on a primary basis, “while ensuring the protection of existing services in those bands and, as appropriate, adjacent bands, and not constraining future development of these services.”
The Radio Society of Great Britain (RSGB) released a statement this week, in part pointing that as proposed, the French resolution “is not an eviction or re-allocation of amateurs, but nonetheless is unwelcome and presents significant challenges. Unlike some other bands where amateurs do share, aeronautical applications are amongst the most difficult due to the altitudes and long free-space distances involved.”
