This is a new listing of the 80 Channel uhf CB radios, ACMA approved, no license required.
The older and more popular 40 channel UHF CB radios, are still compatable with the first 40 channels of the new 80 channel band.
Arguably, the narrower channel bandwiths on the new 80 channel radios may degrade the audio quality slightly.
I remember reading about the new 80 channel band over 18 months ago, as far as i know, the new uhf band has been approved since early 2011.
Eventually there will be more repeater channels over the next three years, frequencies have been allocated for these. Existing repeater channels will remain the same as far as i know.
Note the original 40 channel frequencies and allocations will remain the same at this point.
It is proposed that equipment using 25 kHz spacing (40 channel equipment) be phased out by 2017. The ACMA plan to review this policy in 2016.
