UHF CB Channel Guidelines


UHF CB Channel Guidelines

Always listen on a channel (or observe the receive signal level meter) to ensure it is not already being used before transmitting. Channels 5 and 35 are used for emergency channels. CTCSS and DCS will not operate on these channels. Please follow these guidelines for channel use in Australia:

  • Channels 05 and 35 are Emergency Channels.
  • Channel 11 is a Calling Channel.
  • Channels 22 and 23 are for telemetry and telecommand applications, channels 61, 62 and 63 are for future use and TX is inhibited on these channels.

General communication is accepted on all other channels with these guidelines:

  • Channel 40 - road channel (Australia).
  • Channels 01-08 (and 31-38), and Channels 41-48 (and 71-78) are repeater channels.

Important information - 80 Channel UHF CB channel expansion

To provide all users additional channel capacity within the UHF CB Band. The ACMA will change the majority of the current wideband 40 channel use to narrowband channel use. This allows for additional channels to be added, up to 80 Channels.

This simply means that the new narrowband radio you have purchased will have more channels than older radios. Please refer to the guidelines above and the channel chart for further channel information. A list of currently authorised channels can also be obtained from the ACMA website in Australia and the MED website in New Zealand.
