<div>New UHF Citizen Band radio equipment standard </div>
<div> </div>
<div>The Australian regulator, ACMA, is seeking public comment on a draft UHF Citizen Band (CB)* equipment performance standard, Radiocommunications Standard 2010.</div>
<div> </div>
<div>It is intended that the existing standard will be revoked and replaced with the proposed standard on 1 January 2011.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>Submissions should be provided by close of business on 12 October 2010.</div>
<div> </div>
<div>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.</div>

<div>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.</div>
