Restraint Urged in Response to 2-Meter Reallocation Proposal

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.”

Any consideration to allocate additional services in a band that’s already allocated on a primary basis to an incumbent service — Amateur Radio, in this case — must begin with a sharing/compatibility study. The IARU has expressed “grave concern” to any proposal that would include 144 – 146 MHz in a WRC agenda item and has pledged to make every effort to fully protect Amateur Radio interests and seek the support of regulators.

At the Prague meeting, only Germany opposed the proposal, which has been carried forward to the higher-level CEPT Conference Preparatory Group (CPG) meeting in August. Support from at least 10 CEPT administrations and fewer than six in opposition would move the issue forward as a CEPT resolution, making it highly likely that it would appear on the agendas of WRC-19 and WRC-23.

In a post to the Moon-Net news group, Deutscher (German) Amateur Radio Club (DARC) Frequency Manager Bernd Mischlewski, DF2ZC, stressed the importance that Amateur Radio speak with a single voice and asked the Amateur Radio community to refrain from contacting individual administrations or
