ARLA/CLUSTER: Novo Standard para CB UHF na Australia

[João Costa > CT1FBF]

New UHF Citizen Band radio equipment standard

The Australian regulator, ACMA, is seeking public comment on a draft UHF
Citizen Band (CB)* equipment performance standard, Radiocommunications
Standard 2010.

It is intended that the existing standard will be revoked and replaced with
the proposed standard on 1 January 2011.

>From April 2008 to April 2010, the ACMA reviewed the arrangements for the
radiofrequency spectrum in the 400 MHz band, which incorporates the UHF CB
band.

As a result of the review the ACMA decided to restructure the UHF CB band
into eighty 12.5 kHz wide channels from the existing forty 25 kHz wide
channels.

The proposed standard provides performance limits and test methods for 12.5
kHz channel operation in the UHF CB band, which will transition to 12.5 kHz
channel operation over the period 1 January 2011 to 1 January 2016.

To assist with the transition to 12.5 kHz channelling the new standard is
proposed to provide grandfathering arrangements for current 25 kHz channel
equipment.

Submissions should be provided by close of business on 12 October 2010.

For a copy of the revised standard and information about making a submission
take a look at the link on the email and internet editions of this
broadcast.

UHF Citizen Band (CB)* - UHF CB is a class-licensed (meaning licence-free
use for most users) citizen's band radio service authorised by the
governments of Australia and New Zealand in the UHF 477 MHz band.[1] UHF CB
provides 40 channels, including 16 channels (8 output, 8 input) allocated to
repeater stations. It is similar in concept to the 40 channels used in
United States' HF CB allocation, which is also available in Australia and
New Zealand.
