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.

2 300 - 2 450 MHz

The 13 cm band

This bandplan is the simpliefied version, without the footnotes. If you want to have the fully detailed bandplan please refer to the VHF Handbook

 IARU Spectrum Requirement

The amateur service requires retention of access to the band 2300 – 2450 MHz and upgrading where possible the band 2390 – 2450 MHz to primary status, and the amateur-satellite service requires retention of the band 2400 – 2450 MHz.

The band 2300-2450 MHz is allocated to the Amateur Service on a secondary basis in all three Regions. Actions by WARC-92, WRC-07 and certain administrations in their domestic allocations have reduced the amount of spectrum within this band available to the Amateur Service.

The band 2400-2500 MHz is used for ISM applications and is increasingly congested by (unlicensed) low-power devices such as radio local area networks (RLANs) creating significant interference levels. Substitute spectrum for the Amateur Satellite Service, which is restricted to the ISM segment, is therefore sought.

430 - 440 MHz

The 70 cm band

This bandplan is the simpliefied version, without the footnotes. If you want to have the fully detailed bandplan please refer to the VHF Handbook

IARU Spectrum Requirement

The amateur services require the establishment of the band 430 – 440 MHz as a worldwide exclusive band, with continued sharing of 420 – 430 MHz and 440 – 450 MHz where now permitted. In addition, the deletion from the Radio Regulations of footnotes for fixed and mobile operation in some countries in the band 430 – 440 MHz is sought

28000-29700 kHz

The 10 meter band


IARU Spectrum Requirement

Retention of this popular band is essential to the amateur and amateur-satellite services.

Considerations

This allocation is extensively used for both terrestrial and satellite communications. Modes that cannot be accommodated on lower-frequency bands owing to their inherent bandwidths can be accommodated here, offering (under favourable propagation conditions) the only opportunity for international communication via these modes. While no additional terrestrial allocation is imperative at this time, retention is extremely important for absorbing growth in HF amateur service activity.

24890-24990 kHz

The 12 meter band


IARU Spectrum Requirement

The needs of the amateur and amateur-satellite services would be best served by an allocation of 250 kHz in this vicinity.

Considerations

The band 24890 – 24990 kHz was allocated to the amateur service at WARC-79, but full implementation was delayed for several years pending re-accommodation of fixed service stations. Now, most administrations permit amateurs to use this allocation. It has proven to be very popular, particularly at those times when the MUF is below the wider and extremely popular 28-MHz band. Monitoring indicates that amateur utilisation of this band is higher than the utilisation of adjacent bands by other services.

Norway

Norway allows amateur operations in a wider range. 24740-24890 kHz is allocated to the amateur service on secondary basis, 1kW  (6 kHz max bandwidth)

21000-21450 kHz

The 15 meter band


IARU Spectrum Requirement

Retention of this important allocation, which is only barely adequate for amateur service needs, is absolutely essential.

Considerations

On the basis of congestion during daylight hours when the MUF exceeds 21 MHz, an expansion of this band by 50 kHz could be readily justified. However, in view of the greater importance of meeting other amateur service requirements that are as yet unfulfilled, such an expansion is not of the highest priority.

18068-18168 kHz

The 17 meter band

IARU Spectrum Requirement

The growing needs of the amateur service would best be addressed by an exclusive allocation of 250 kHz in this vicinity.

Considerations

The band 18068 – 18168 kHz was allocated to the amateur service at WARC-79, but full implementation was delayed for some ten years pending the re-accommodation of fixed service stations. Now, most ITU member administrations permit their amateurs to use this allocation. It has proven to be very popular with operators who wish to avoid the congestion in the 14-MHz band and who are flexible in selecting the best operating frequency for a given path. Monitoring indicates that amateur utilisa

14000-14350 kHz

The 20 meter band


IARU Spectrum Requirements

The growth of the amateur service and its heavy dependence on this band for international communication using CW, SSB, and digital modes justifies a return to an allocation of 14000 – 14400 kHz.

Considerations

This band is undoubtedly the most popular amateur band for international communications. It bears an extremely heavy load of both CW and SSB traffic. In recent years, amateurs have found it increasingly difficult to accommodate the newer digital modes within the 14-MHz allocation, thereby limiting the contribution of the amateur service to the experimentation with new techniques.

At the Washington Conference of 1927 this allocation was established at 14000 – 14400 kHz, but at the Atlantic City Conference of 1947 it was reduced by 50 kHz, to 14000 – 14350 kHz.
