UHF Frequencies

Radio Frequencies (Talk Channels) for Two Way Radio are allocated by the ACMA (Australian Communications Media Authority) which is the Federal Governing body in charge of Licencing of Two Way Radio Frequencies.

There are 80 Channels of free UHF CB Two Way Radio Channels that have been set aside for the general public to use. These frequencies are in the UHF Band between 476.4250 and 477.4125 MHz. Any frequencies outside of this band are for COMMERCIAL USE ONLY and all need to be licenced. 

It is highly illegal to use any COMMERCIAL frequncy outside of the CB Channels without a Licence on any Two Way Radio. Very heavy fines are levied and confiscation of equipment may take place should anyone be caught using Two Way Radio equipment on commercial channels without a license. This is like driving a car without a drivers license, the normal person would not consider doing this and you should not operate on commercial talk channels without a radio frequency license either. 

Licences are not that expensive and to apply you should be a commercial entity and if you wish to apply for a licence we will be glad to help with this process.

Licenses for Repeater Channels 44 & 45 will not be licensed for an additional 6 to 12 months to allow extra time for owners of Channel 5 Emergency repeaters to upgrade equipment to meet the new standards    
 
Channels 1 to 8 and 41 to 48 - Repeater Channels Press the DUPLEX button on your radio to used any available repeaters.
Channel 5 & 35 - Emergency use only - Monitored by Volunteers, No general conversations are to take place on this channel
Channels 22 & 23 - Data transmissions only (Excluding Packet)
Channels 31 to 38 and 71 to 78 - Repeater inputs - Do not use these channels for simplex transmissions as you will interfere with conversations on channels 1 to 8 and 41 to 48.
 
The Australian Government has legislated that channels 5 & 35 on the UHF CB Band are reserved for emergency use only 
As at January 2007 the maximum penalties for the misuse of the legally allocated CB emergency channels are:
  • For general misuse - if an individual 2 years imprisonment, otherwise $165,000 (a $220 on-the-spot fine can be issued in minor cases); or
  • For interference to an Emergency call - if an individual 5 years imprisonment, otherwise $550,000
