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.

Norwegian regulations change

As of October 31, 2012, the Norwegian P & T Authority has made changes to the Norwegian amateur license regulations. The major changes are:

  1. Permission has been given to use 472 - 479 kHz (max. 100 W transmitter power output; max. 1 W EIRP). Hence the former permission to use 493 - 510 kHz has been stopped. 
  2. Permission has been given to use 70.1875 - 70.2625 kHz, EXCEPT in the three Norwegian southwest counties of Hordaland, Rogaland and West-Agder, where there still is commercial traffic within this frequency segment. NRRL had argued that the bulk of Norwegian radio amateurs should not be barred from using the IARU Region 1 calling frequency on 70.200 MHz and vicinities, because of a few commercial stations in the southwest corner of the country. This reasoning has thus been accepted by the Norwegian P&T authority. Hence the permission on 4 m with max. 100 W transmitter power, and max. 16 kHz bandwidth, include the following frequency segments: 
    • 70.0625 - 70.0875 MHz 
    • 70.1375 - 70.3125 MHz* 
    • 70.3625 - 70.3875 MHz 
    • 70.4125 - 70.4625 MHz 

* 70.1875 - 70.2625 MHz not permitted in the counties Hordaland, Rogaland, and West-Agder (southwest Norway).
