UHF CB information about channel uses

UHF Channel Information

Notes about use of CB Channels:

Citizen's Band (CB) is a government allocated range of frequencies on which ordinary Australians can communicate without the need for a licence. In doing so there are some important things to remember. Not every channel is there for you to play on. Some channels have very important roles, for instance channels 1-8 & 31-38 are coupled to provide repeater services. Channels 5 & 35 are allocated by the Australian Government for use as emergency channels and should be kept clear at all times. These channels are monitored for emergency puposes.

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 actual call - if an individual 5 years imprisonment, otherwise $550,000 (no on-the-spot fine can be issued, must go to court)

Note also that the maximum transmission power allowed when using CB is 5 watts.
