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.

The First 4 Metre EME Contact Claimed

Andy Kissack, GD0TEP, on the Isle on Man believes that his EME contact with Willem Badenhorst, ZS6WAB, on 4 metres could prove to be a first. Newsline, reports that It could be a world record on the 4 metre band.
Andy says on his website that following the tests carried out by himself and GD4GNH back in 2006, he finally found a suitable station to try for an EME contact on the 4 Metre band. As a result, Andy and Willem in South Africa tried an EME sked on Friday evening, 13 February. Unfortunately, his masts mounted transmit and receive relay failed due to water ingress.
Their second try was the morning of 15 February. Visibility of the Moon at Andy's location came at 00:38 UTC and at 01:34 he received his first moon echo. About a minute later, Andy and Willem completed what both operators believe to be the world's first 4 metre EME contact using low noise JT65, a digital mode. Screen shots of the QSO are on line at http://www.gd0tep.com
JT65 is a digital protocol intended for Amateur Radio communication with extremely weak signals. It was designed to optimize Earth-Moon-Earth (EME) contacts on the VHF bands, and conforms efficiently to the established standards and procedures for such QSOs. JT65 includes error-correcting features that make it very robust, even with signals much too weak to be heard.
