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.

5 MHz and even more 5 MHz

As a result of representation from the national society URE Spain has gained an extension of the use of several 5 MHz frequencies. Due to expire at the end of June 2014 permission has now been granted to use 5268, 5295, 5313, 5382, 5430 and 5439 kHz until 30th November 2015 with a power of 100W PEP.   Frequencies are thought to be USB dial frequencies.

The Andorran Society URA reports that permission has been granted the use of 5275-5450 kHz until a decision is made at WRC-15.   Permitted power is 100W PEP using CW and SSB with transmission bandwidths not to exceed 3 kHz.

Portugal now has the use of a channel at 5380.5 kHz in addition to those at 5288.5, 5371.5 and 5403.5 kHz.   This is thought to align with the Spanish channel listed as 5382 kHz.

Member Societies are asked to notify either PB2T or G3PSM of any developments concerning 5 MHz.
