144 and 1240 MHz Bands – RSGB information

RSGB volunteers continue to be engaged with IARU and Ofcom on WRC matters including the 144 MHz and 1240 MHz bands as well as WRC-19 Agenda Items in CEPT-PTD (50 MHz, WPT, 5GHz) and CEPT-PT1 (24/47 GHz).

At UK level, RSGB are members of the Ofcom IFPG groups that consider these matters.

The RSGB has updated their special focus page with the latest documents and CEPT meeting minutes. See Proposed WRC-23 Agenda Items at

June 21 – RSGB Update on 144MHz and 1240 MHz band threats


CEPT Project Team A, responsible for some aspects of the CEPT position for WRC-19, met in Prague from June 17-21. The meeting minutes are available for download

Regarding the 1240-1300 MHz band the minutes say:

The representative of the European Commission (EC) stated that, RNSS systems are global by nature, and that the radio amateur service is allocated in all regions. Once RNSS receivers (including Galileo E6 receivers) are deployed ubiquitously, the number of interference cases coming from radio amateur emissions will increase significantly and represent an important burden to Administrations, unless clear guidelines are available in order to drive the amateur community towards an appropriate usage of their allocation.

For these reasons, the EC believes that the French proposal of a WRC-23 agenda item is essential in order to complement the work being started within CEPT, and to find a sustainable solution for all parties. Also, the EC considers that WRC-23 is the right time for a decision enabling the better regulation of the RNSS-amateur coexistence at international level, as Galileo will start providing freely available high accuracy services in the 1260-1300 MHz band on a global basis from 2020.

The EC noted that some of the 7 Administrations which objected to the French contribution are open to consider a revised version of the proposal, and therefore believes that relevant support may be achievable at CPG level, following further discussions until end August.

Regarding the 144 MHz band the minutes say:

The representative of the IARU stated that, the IARU views with grave concern the element of the WRC-23 agenda item proposal 1.6 in the AI10 ECP, on studies towards a possible new allocation to the aeronautical mobile service in the band 144-146 MHz. This band is an important and the only globally harmonised primary allocation to the amateur and amateur satellite services in the VHF range. Examination of the RR below and above the 144-146 MHz range suggests that alternative proposals could be developed that could provide further spectrum for the aeronautical applications without impacting on this amateur service spectrum. The proposal provides no justification for addressing this band and the IARU believes that sharing with airborne systems is likely to be difficult and will lead to constraints on the development of the amateur and amateur satellite services in this band.
