During the week 15 – 19 February, the preparatory work for WRC-23 agenda item 9.1b continued in ITU‑R Working Party 4C (WP4C). The WRC agenda item has initiated technical studies on coexistence between the radio navigation satellite service (RNSS) and the amateur services in the 23cm band. As usual, the IARU participated in the meeting and delivered key information on amateur activities in this important microwave band. This information is vital to ensure the amateur services are realistically represented in the studies as they move forward.
It remains vital that national amateur communities present their views on the importance of this band to their national regulators in a consolidated and consistent manner.
To assist with this the IARU-R1 is developing supporting material that member societies can refer to when addressing the topic with their national regulator.
The work on this topic will continue throughout the year and beyond both in ITU‑R and in the regional telecommunications organisations and the IARU is committed to ensure every organisation understands the amateur position on this important microwave band.
