TX4400 DIN size UHF radio

  

A trusted DIN size radio, built for the harsh Australian climate

The TX4400 radio is Australian designed and built and is one of the most advanced UHF Citizen Band radios available.

The TX4400 combines the very latest in electronic hardware with the most up-to-date computer aided design and manufacturing techniques to produce an extremely versatile mobile radio with outstanding specifications, performance and a 3 year GME warranty .

The TX4400's DIN sized case allows it to be conveniently installed into a dashboard or console and its strong diecast aluminium chassis makes it the most robust transceiver of its kind. With just three rotary controls and five touch keys, the TX4400's extensive features are easy to operate.

One of the a major feature benefit to be added to the TX4400 is that the extra receive channels can now be User programmed into the radio channels from 41 to 60. Once activated the user can set and store any frequency between 465 and 485 MHz This can be changed or the channel deleted at any time after initially being set, and all from the front face controls. No computer connection or software required. This feature is available on units with a serial number higher than 10803340.
