IARU and CEPT WRC-23 Preparations

[IK0ZCW]

Mar 26, 2021 - Spectrum - Barry, G4SJH

IARU continued engagement in the WRC-23 preparations in the CEPT RTO during March 2021 at the second meeting of the Conference Preparatory Group Project Team A (CPG PTA). This project team develops the CEPT WRC Briefs for several WRC scientific and regulatory agenda items which are of particular interest to the amateur community. Specific attention is being paid to WRC-23 agenda items 1.12, 1.14 and 9.1a. IARU provided a contribution putting forward the agreed preliminary IARU positions for these agenda items. IARU’s overall objective is to safeguard the allocations to the Amateur and Amateur-Satellite services in the co and adjacent frequency bands within the scope of each agenda item. The CEPT briefs have a specific section in which the views of all the recognised international and regional organisations can be placed and the IARU views are now in this section of the draft briefs for each of these agenda items.
