INTrOdUCTION

your GmE tX3345 80 channel is Australian designed and built
and is the most advanced uhF citizen Band radio available.
the tX3345 combines the very latest in electronic hardware
with the most up-to-date computer aided design and
manufacturing techniques to produce an extremely compact
mobile radio with outstanding specifications and performance.
the tX3345 with its controller microphone is designed for
unobtrusive mounting in modern vehicles. the radio case
with its built-in loud speaker and extremely small size can be
mounted in almost any convenient location.

IMPOrTANT INFOrMATION

CONCErNING 80 CH UHF CB rAdIO
the use of the citizen Band radio service is licensed in
Australia by the AcmA radio communications (citizens
Band radio stations) class licence and in new Zealand by
the ministry of Economic development new Zealand (mEd).
A General user radio licence for citizens Band radio and
operation is subject to conditions contained in those licences.
the class licence for users and equipment operating in the
cB/Prs 477 mhz band has been amended. this radio meets
the new 80 channel standard.
in simple terms the same amount of spectrum is available;
however, radio transceivers can now operate in a narrower
bandwidth and hence use less spectrum. these radios are
generally referred to as narrowband or 12.5 khz radios. By
using 12.5 khz channel spacing instead of 25 khz, the 40

channels originally allocated can now be expanded to 80
channels thereby doubling the channel capacity and relieving
congestion in the uhF cB/Prs band.
original 40 channel wideband radios will continue to operate
on the original 40 channels, however they will not be able
to converse on the newer channels 41 – 80. the newer
narrowband radios will be able to converse with all older 40
channel wideband radios on all channels
1 to 40 as well as the newer channels allocated from 41 to 80.
the mixing of narrowband and wideband radios in the
same spectrum can cause some possible operating issues of
interference and varying levels of received volume
Possible issues
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 best performance.
When an older wideband radio receives a signal from a new
narrowband radio, the speech may sound quiet – simply adjust
your radio volume for best performance.
depending on how close your receiving radio is to another
transmitting radio, there can be interference from the
transmitting radio if it is using a channel adjacent to the
channel you are listening to. simply try going up or down a
few channels from the currently selected channel. the above
situations are not a fault of the radio but a symptom of
operating wideband and narrowband radios in the same
bandwidth. this possible interference will decrease over time
as the population of wideband radios ages and decreases.
