World Radiocommunication Conference Approves Global 60 Meter
Allocation!
The Plenary Meeting of the 2015 World Radiocommunication
Conference (WRC-15) in Geneva has approved an allocation of 5351.5-5366.5 kHz
to the Amateur Service on a secondary basis, with a power limit of 15 W
effective isotropic radiated power (EIRP).
The November 18 decision on Agenda Item 1.4 was adopted on two
back-to-back readings. Some Region 2 countries — but not the US — will be
permitted up to 25 W EIRP.
With this action, and despite conditions that are more restrictive
than had been hoped at the start of the Conference, the Amateur Service
has obtained its first new global HF allocation since 1979.
While the Final Acts of the conference are expected to take effect on January 1, 2017, the new band will not become available to amateurs until their national telecommunications administration amends its rules and licensing conditions.
While the Final Acts of the conference are expected to take effect on January 1, 2017, the new band will not become available to amateurs until their national telecommunications administration amends its rules and licensing conditions.
Those administrations that already permit amateurs to operate in
the 5 MHz range under certain conditions and on a not-to-interfere basis,
including the FCC, will be considering whether, how, and when to modify those
arrangements in light of the international allocation.
The 60 meter band or 5 MHz band is
a relatively new amateur
radio allocation, first introduced in 2002, that was originally
only available in a few countries, such as the United
States, United
Kingdom, Norway, Finland, Denmark, Ireland and Iceland. Over a
number of years however, an increasing proportion of countries'
telecommunications administrations - together with their government and
military users - have permitted Amateur Radio operation in the 5 MHz area
on a short or longer term basis, ranging from discrete channels to a frequency
band allocation.
At the closing meeting of the 2015 ITU World Radiocommunication
Conference (WRC-15) on 27 November 2015, amongst the Final Acts
signed into the International Radio Regulations was one approving A
Worldwide Frequency Allocation of 5351.5–5366.5 kHz to the Amateur Service
on a secondary basis.[1][2] The
ITU's enhanced band allocation limits most amateurs to 15 watts effective isotropic radiated power (EIRP),
with some countries allowed up to 25 W EIRP.[1][2] The
ITU allocation came into effect January 1, 2017,[2] after
which each country's national administration must formally revise their rules
to permit amateur operation.
Prior to WRC-15, all 5 MHz Amateur allocations made by
individual administrations were in accordance with Article 4.4 of
the ITU Radio Regulations, which requires non-interference with other radio
services. Where two-way amateur radio communication is authorized on 60 m,
it has generally been within the frequency range 5250–5450 kHz, but the
whole of this range is not necessarily available and allocations vary
significantly from country-to-country. This has been particularly true in
latter years since the award at WRC-12 of the range 5250–5275 kHz to the
Radiolocation Service, thus effectively reducing the former frequency range
down to 5275–5450 kHz.
In a number of countries the allocation is still channelized at
present, whereas others have block or band allocations or a mixture. Voice
operation is generally in upper
sideband (USB) mode to facilitate inter-communication by
non-amateur service users if necessary. In the United
States and its Dependencies, channelized USB is mandatory. Where
channelization is used, the USB suppressed carrier frequency (a.k.a. 'dial'
frequency) is normally 1.5 kHz below the quoted channel frequency. For
example, 5403.5 kHz is the 'dial' frequency for the channel centered on
5405 kHz. The "center" of the channel is based on the assumption
that the bandwidth of SSB transmissions are 3 kHz, at most. Transmitters
that are capable of wider SSB bandwidths should be adjusted for 3 kHz
bandwidth or less so their emissions stay within the allocated channel.
