Early in 2011 new AS/NZS Standards came into effect allowing operators to use additional narrowband channels
and also use narrowband transmissions on some current wideband channels.
Why did the ACMA increased the number of available UHF CB channels?
To provide additional channel capacity within the UHF CB Band the ACMA has changed the majority of the current
wideband 80 channel use to narrowband 80 channel use.
Wideband channel use will be gradually phased out as users upgrade their existing radio’s. This increased the
number of channels up to 80, 75 of which are useable voice channels.
This means that the new Oricom narrowband radio you have purchased will have more channels than older
wideband radios. Some of these channels are locked and cannot be used, (see the attached channel chart for more
information).
What issues may users experience during the transition phase?
When a new narrowband radio receives a transmission from an older wideband radio the speech may sound loud
and distorted - simply adjust your radio volume for the best listening performance. When an older wideband radio
receives a signal from a new narrowband radio the speech may sound quieter - simply adjust your radio volume for
best listening performance. When operating a narrowband radio or Channel 41 - 80 interference is possible from
wideband radios transmitting on high power or on adjacent frequency.
The issues described above are not a fault of the radio but a consequence of mixed use of wideband and
narrowband radios.
It is expected that as older wideband radios are removed from service that this issue will be resolved. Most radios
in use will be narrowband eliminating this issue.

Duplex operation via Repeaters
This feature allows to use local repeater stations that are designed
to automatically re-transmit your broadcast over a large area thus
giving you increased range.
Repeaters stations are privately operated radio systems installed
throughout Australia.
For example, if you wish to access a repeater station in your area
which operates on channel 2 you only need to set the Duplex
access on this Channel.
So, if you are in the range of a local repeater which transmits on
channel 2, after setting your radio to allow access of the repeater
on that channel, you will select channel 2 as normal, but during
transmit operation your radio will automatically transmit to the
repeater on channel 32.
