RAC Bulletin 2012-010E – Good News from WRC12 – A New Band at 600 metres.
At its Plenary meeting held 14 February 2012 in Geneva the World
Radiocommunication Conference approved a new secondary frequency
allocation to the Amateur Radio Service at 472 to 479 kHz. Having
passed First and Second Readings it is normally a formality that this
change be included in the WRC-12 Final Acts when the Conference
concludes February 17th. The Table of Frequency Allocations would then
be amended accordingly.
The new band at 600 metres will represent the return of amateurs to
the medium waves – an area of spectrum we have not had access to since
the earliest days of radio regulation.
As a secondary user, amateur radio shares 472 – 479 kHz with the
Maritime Mobile Service who are the primary user in all three ITU
Regions and with the Aeronautical Radionavigation Service who are a
Secondary user except as noted in the following.
The new allocation to the amateur service is accompanied by several
footnotes including, i) a number of countries will identify their
intent to elevate the status of their Aeronautical Radionavigation
Service to Primary as a step in ensuring protection from secondary
users, and ii) the power which radio amateurs may use in 472 to 479
kHz will be limited to 5 watts (e.i.r.p.) except for amateur stations
within 800 km of the borders of a number of countries – principally
Russia, many of the former Soviet bloc and the Arab states. For those
affected amateurs the limit will be 1 watt.
It is, of course, up to individual administrations to authorize use of
the band by their amateurs. In the case of Canada, it seems certain
that such authorization will be forthcoming; however, the process
which has to be followed may take some time.
Canadian radio amateurs have played a central role in arriving at this
successful outcome. The documents submitted through the ITU in support
of this allocation were largely authored by Canadian amateurs – as was
the important work done in assessing the efficiency of the antennas
radio amateurs would likely use. Canadian amateurs have been present
at ITU meetings in Geneva since 2009 to advance the cause of this
allocation. Our regulator, Industry Canada, has been outstanding in
their support of our work and in ensuring today’s success. Finally,
our colleagues in the IARU, ARRL, RSGB, and DARC have all played major
