INTrOduCTION
Your GME TX3420 radio is Australian designed and built
and is the most advanced UHF Citizen Band radio available.
The TX3420 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 TX3420's small size means it can be mounted in almost
any convenient location and its strong diecast aluminium
chassis makes it the most robust transceiver of its kind.
With just two rotary controls and four touch keys, the
TX3420 is easy to operate.
EMERGENCY CHANNELS
The ACMA has allocated channels 5/35 for emergency use
only. Channel 5 is the primary Simplex Emergency Channel.
Where a Channel 5 repeater is available, you should select
Duplex on CH 5.
Note: Channel 35 is the input channel for the Channel 5
repeater therefore Channel 35 should also not be used for
anything other than emergency transmissions.
TElEmETry ChaNNElS
ACMA regulations have allocated channels 22 and 23
for telemetry only applications and have prohibited the
transmission of speech on these channels. Consequently
the TX3420 has a transmit inhibit applied to channels 22
and 23.
