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
NOTE
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.
Interference / Poor Audio
When a new narrowband radio receives a signal from an older
wideband radio the speech may sound loud - however the UH8010S/
NOTE
UH8020S built-in AVS (Automatic Volume Stabilizer) circuitry will
detect and manage incoming audio to comparable levels.
Narrowband radios operating on CH41 - CH80 may encounter
interference from a nearby wideband radios transmitting on high
power on an adjacent channel (frequency).
When an older wideband radio receives a signal from a new
narrowband radio the speech may sound quiet - the wideband radio
user simply adjusts their radio volume for best performance.
The above situations are not a fault of the radio but a symptom of mixed
wideband and narrowband radios in current use. It is expected that as
older wideband radios are phased out this issue will be eliminated.
