The International Amateur Radio Union (IARU) is a federation of national associations of certified radio amateurs, representing over 150 countries and separate territories around the world.

The three IARU Regions are organised to broadly mirror the structure of the International Telecommunications Union (ITU) and its related regional telecommunications organisations. The Regions comprise:
- IARU Region 1: Europe, Africa, the Middle East and Northern Asia
- IARU Region 2: The Americas
- IARU Region 3: Asia-Pacific

The IARU represents the interests of the Amateur Radio Service worldwide to relevant international organisations, promoting the interests of amateur radio and seeking to protect and enhance its spectrum privileges.

ITU-R Working Party 5A meets in Geneva

wp 5aA number of ITU-R Study Group 5 Working Goups meet in Geneva 6-16 November 2017. Working Party 5A (WP 5A) deals with the Land mobile service above 30 MHz (excluding IMT), wireless access in the fixed service and the amateur and amateur-satellite services. Working Group 5A1, chaired by Dale Hughes VK1DSH, is reponsible for the preparation of World Radiocommunication Conference 2019 (WRC-19) Agenda Item 1.1, considering an allocation of the frequency band 50-54 MHz to the amateur service in Region 1. The Working Group consists of a mix of radio amateurs from all three IARU Regions, administrations from all over the world and other interested parties like meteorologists and military.

Based on input documents -and there are lots of them- the meeting prepares the so-called CPM text, required for the Conference Preparatory Meeting to be held in February 2019. The CPM report forms the basis for decision taking at WRC-19.

Preparatory Meetings are usually held at the headquarters of the International Telecommunication Union (ITU) in Geneva. Amateurs present in WP 5A include 5A1 Chairman Dale Hughes VK1DSH, IARU Vice President Ole Garpestad LA2RR, IARU repesentative Dave Court EI3IO, CEPT coordinator Hans Blondeel Timmerman PB2T, CITEL coordinator Flávio Archelangelo PY2ZX, ARRL representative Jonathan Siverling WB3ERA, DARC representative Ulrich Mueller DK4VW, JARL representative Ken Yamamoto JA1CJP, RAC representative Bryan Rawlings VE3QN and RSGB representative Murray Niman G6JYB. On the photo VK1DSH explains the basics of amateur radio.
