TX3820U UHF 25W local mount commercial radio

Packed with an impressive list of features. With its 'Flash' upgradeable microprocessor and flexible programming, future upgrading of your two-way radio
requirements becomes a reality. The compact modular design of the TX3820U incorporates a rugged die-cast aluminium chassis which allows it to
withstand constant vibration and extreme temperatures.

The TX3820U provides a full 25 Watts of output power without compromising the size of the radio.
The length of the chassis has only increased by 50 mm compared with the existing TX3600.
When used with the optional remote conversion kit, which separates the controls from the main body of the transceiver, the TX3820U becomes possibly
the smallest 25 Watt commercial radio in Australia.

Taking advantage of the full die-cast chassis and top cover, this design allows the unit to dissipate the heat generated by the 25 Watt output power
whilst providing a very rugged and robust radio. GME is so confident in the design we offer a full two (2) year manufacturer's warranty.

Installation is simple. Measuring just 128 mm (W) x 165 mm (L) x 29 mm (H) the TX3800 easily fits into the confines of modern vehicles.
For traditional DIN sized console mounting the MBD001 DIN adaptor kit allows the TX3820U to be easily installed or removed.
The built-in speaker can be mounted facing either upwards or downwards for clear audio.
