As the WRC-23 approaches so the studies regarding AI9.1b (23cm and RNSS) are working towards conclusions. However the IARU is not content that all the operational aspects of the amateur service usage of the 1 240- 1 300 MHz band are being properly considered to develop an acceptable compromise for all concerned parties. You can find some more detail on the areas of concern in this discussion paper posted in the global IARU WRC23 web pages on this topic. See IARU Perspective on the AI9.1b Progress — September 2022.

As WRC23 gets closer so the preparatory activities for all the agenda items are increasing in intensity. The most pressing for the amateur community is the 23cm band radio navigation satellite service (RNSS) coexistence agenda item 9.1b. The IARU engagement is continuing with the studies in the regulatory institutions as well as amongst the amateur community. As detailed proposals are starting to emerge so the amateur community needs to be ready to defend its interests in this band.

Most recently the Region 1 PRC and SRLC collaborated to provide a consultation response to the European Radio Spectrum Policy Group (RSPG) that develops “Opinions” on the various WRC23 agenda items used by the European Union to develop its positions on the agenda items. Of course the 23cm band related agenda item 9.1b features heavily in the response. The full IARU R1 response can be found here. This is a parallel activity to the EU consultation to which the IARU responded just a few weeks ago (here).

Following the presentations given during the IARU R1 interim conference and the HamRadio2022 event, the IARU was kindly invited to present the 23cm band situation to the eme community at the 19^th EME conference in Prague. Reactions were mixed. However the IARU maintains its objective to find a solution that can facilitate all the amateur radio applications active in the band today (including eme operations) even if some compromises will be inevitable.

To progress the 23cm band studies, ITU‑R Working Party 4C will meet during the second week of September. At this meeting the technical studies regarding the amateur service and radio navigation satellite service will be developed further. The IARU global 9.1b team is preparing contributions and will be participating in the meeting.

During the same week the European CEPT will be busy with its own Conference Preparatory Group (CPG) project team (PTA) focussing on the future WRC agenda items (so-called WRC Agenda Item 10). The discussion will develop the CEPT views on those items that CEPT will propose. Already some draft proposals are touching on spectrum bands of interest to the amateur service therefore IARU volunteers will be attending and making contributions this meeting too.

In a collaboration between the SRLC and the PRC an IARU R1 response has been provided to the European Union consultation on the WRC23 agenda items. All the agenda items of interest to the IARU are covered with particular attention paid to the AI9.1b issue on the GALILEO / 23cm band amateur service coexistence. This is an important messaging activity and the IARU response again underlines the IARU view that with only two cases of interference recorded globally, the potential for interference is being over-stated and that any regulatory solutions should be proportionate, realistic and appropriate and should not hinder the future development of amateur services. The IARU would be pleased if member societies could share these same views with their national regulators. The full IARU R1 response can be found [here].

The PRC/SRLC is also developing a response to the European Commission Radio Spectrum Policy Group (RSPG) on the same topics.

Secondly the CEPT project team SE40 that is carrying out the CEPT studies on the RNSS/23cm band topic met during the week 25 – 28^th July 2022. The IARU provided a contribution and participated in the meeting supported by USKA. Good progress was made but further work continues to be required to finalise the conclusions from the studies. The IARU continues to be concerned about the lack of consideration being given to the low probability of interference and more work is needed on this aspect. A summary report can be found here.
