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.

Bulgarian radio amateurs obtain temporary access to the digital portion of 50 MHz band

Thanks to the effort made by BFRA (Bulgarian Federation of Radio Amateurs), the Communications Regulation Commission (CRC) with the Permit No. 02353 / 05.09.2019 has provisionally authorized to use the 50.310 MHz to 50.335 MHz segment.

This band is provided free of charge to all Bulgarian radio amateurs to be able to work and experiment with the new modes of operation in recent years.

BFRA is actively working with all institutions involved in extending the 6 meters band, and we hope that our efforts will be successful soon.
