A worldwide community
Thousands of telecommunication professionals trace the beginnings of their
careers to the exploration of the radio spectrum that was made possible by their
early involvement in amateur radio. Many continue to pursue their passion for
radio communication as a hobby, as well as a vocation. The amateur radio service
and the related amateur-satellite service (collectively called the "amateur
services") are unique, in that they are defined in the Radio Regulations as
being open to those whose interest in radio is "solely with a personal aim and
without pecuniary interest."
The operational and technical standards of the amateur services are as high
as any other radiocommunication service. A total of some three million
individuals in nearly every country of the world, from the very young to the
very old, have demonstrated their qualifications and have been issued amateur
radio licences by their administrations. These individuals constitute the global
amateur radio community. They have formed radio clubs at the local level, and
technical educational organizations at the national level, for the purpose of
increasing the understanding of telecommunication technology and extending the
benefits of radio communication to the wider community.
Participating in ITU
In ITU, the amateur radio community is represented by the International
Amateur Radio Union (IARU), a worldwide federation of national societies in
159 countries and territories. The IARU is an active Sector Member of the ITU
Radiocommunication Sector (ITU–R) and Telecommunication Development Sector
(ITU–D), and is a regular participant in world radiocommunication conferences
An early interest in amateur radio
can lead to an exciting career.

Physics for the discovery of binary pulsars
The "self-training, intercommunication and technical investigations" that
constitute the defined purposes of the amateur services are made possible by
providing access to the radio spectrum by means of allocations of frequency
bands. The principal objective of the amateur radio community at any WRC is to
preserve this access to spectrum.
At the present time, allocations to the amateur service begin in the vicinity
of 1.8 MHz (in the case of the amateur-satellite service, at 7 MHz) and appear at intervals throughout the Radio
Regulations’ "Table of Frequency Allocations" up to 250 GHz. Use of these bands
is managed through a combination of national regulations by telecommunication
administrations and through self-management by the amateur radio community
IARU Secretary David Sumner has observed that "the specific service rules for
the amateur and amateur-satellite services, Article 25, were reviewed and
modified at WRC-03. These modifications increased the emphasis on the use of
amateur stations in providing communications in support of disaster relief and
eliminated a long-standing requirement that amateur operators using frequencies
below 30 MHz must demonstrate ability in Morse code. As a result, since 2003 the
number of amateur stations equipped to operate below 30 MHz has risen sharply."
Items at WRC-07
While most of the agenda items under consideration at WRC-07 do not directly
affect the amateur and amateur-satellite services, there are four that are of
particular interest to radio amateurs:
Harmonization of frequency allocations
As befits radio services that are global in scope, most of the frequency
allocations to the amateur services are on a worldwide basis, with a few
regional variations. Some country footnotes provide for alternative or
additional allocations in some of these frequency bands. The amateur radio
community seeks increased harmonization of frequency allocations, through the
reduction and avoidance of country footnotes that reduce the availability of
bands that are allocated internationally to radio amateurs.
Maintaining and extending allocations
WRC-07 will review the allocations to all services in the high frequency (HF)
bands between 4 and 10 MHz, with certain bands excepted. At present, the only
allocation to the amateur service in this frequency range is at 7 MHz. WRC-03
expanded the amateur allocation in Regions 1 (Africa and Europe) and 3 (Asia and
Australasia) from 7 000–7 100 kHz to 7 000–7 200 kHz, effective in March 2009,
and maintained the allocation of 7 000–7 300 kHz in Region 2 (the Americas). The
band 7 000–7 200 kHz is excluded from consideration at WRC-07.

To fulfill a longstanding requirement that was only partially met at WRC-03,
the amateur service seeks to maintain its allocation of 7 200–7 300 kHz in
Region 2 and to extend this allocation to Regions 1 and 3, as outlined in the
Report of the Conference Preparatory Meeting (CPM) for WRC-07.
With only one allocated frequency band between 4 and 10 MHz, stations in the
amateur service are unable to be as flexible as those in other HF services in
adjusting their operating frequency to suit varying propagation conditions. To
improve the reliability of communication at any time of day and to facilitate
the role of the amateur service in support of disaster mitigation and relief, a
worldwide secondary allocation of 150 kHz is sought in the frequency range just
above 5 MHz, as proposed in the CPM Report for WRC-07.
Secondary allocation in the low-frequency range
A more straightforward issue is the conference’s consideration of a secondary
allocation to the amateur service in the frequency band 135.7–137.8 kHz. At
present, the amateur service has no frequency allocations lower than about
1.8 MHz. While the radiation efficiency of practical antennas has limited the
effectiveness of communications at this order of frequency, digital processing
now makes it possible to recover weak signals that previously would have been
obscured by atmospheric noise. This opens a window of opportunity for amateurs
to conduct technical investigations in the low-frequency range.
More than 20 administrations have permitted private individuals, virtually
all of them licensed radio amateurs, to experiment with transmission and
reception on various frequencies between 73 kHz and 200 kHz. A regulation from
the European Conference of Postal and Telecommunications Administrations (CEPT)
on the use of the band 135.7–137.8 kHz by the amateur service has been
implemented in 15 European administrations. An international allocation will
harmonize these national arrangements, and a secondary allocation will provide
regulatory protection for the primary services.
Proposals for the WRC in 2011
The amateur radio community wishes to see the following issues considered for
inclusion on the agenda of WRC-11:
- an allocation to the amateur service in the range 50–54 MHz in Region 1,
in order to harmonize this allocation among the three Regions;
- allocation of the band 495–510 kHz to the amateur service on a secondary
or primary basis; permitting the development of reliable groundwave systems
for disaster relief and providing spectrum for digital signal processing
- continued access for amateurs to frequencies at regular intervals above
275 GHz as allocations and protections for other services. (One option is to
provide specific allocations to the amateur services of relatively narrow,
primary bands adjacent to wider, secondary bands);
- in any review of HF allocations, consideration of the expansion of the
amateur bands near 10, 14 and 18 MHz, in order to better accommodate
As always, several observers will be present at WRC-07 on behalf of the IARU.
During the conference, members of the IARU team will be pleased to answer
questions and provide information about the amateur services.
