The
TX3420 is practical and versitile. Through rugged construction, enhanced
features and performance, the TX3420 rewrites the the standard for 477
MHz radios. Easy installation in any vehicle with the remote mounting panel and alternatively, the remote head can be attached directly
to the main unit if required to create a compact one-piece
transceiver.
The microphone includes Channel up/down keys and a Priority Channel button making these features a simple one-handed operation.
In
addition, the TX3420 can be installed into a standard in-dash
DIN slot using the optional MBD001 DIN adapter kit.
Measuring
just 128 mm wide x 117 mm long x 29 mm high (128 mm wide x 31 mm
long x 29 mm for the remote head), the TX3420 is small in
size but huge in performance and built to last. Add to that
the 3 year GME warranty and you have a UHF transceiver that's
unsurpassed in its category.

- Programmable
Scan Function
Scans up to 40 user programmable channels with both Group
and Open scan functions available.
- Remote
or Local Installation Options
The TX3420 can be mounted either remotely using the separate
control head, or locally with the control head attached
to the main unit.
- Quiet
Mode
Selectable on individual channels, the Quiet mode prevents
incoming signals from being heard on selected channels
unless preceded by your selcall code.
- Overvoltage
Protection
Special overvoltage detection circuitry protects the radio
and warns of excessive voltage conditions by flashing
the display.
- 59 Extra User Programmable Listening
Channels
The wide band receiver allows the user to program up to 59 listening
channels anywhere within the range of 403-520 MHz using the front panel
keys. A manual-scan feature makes it easy to locate and store active
channels.

Selectable Priority Channel
Lets you programme your normal working or local repeater
channel for instant recall at the press of a button.
- Individually
Programmable Duplex Function
