TX3820U UHF 25W local mount commercial radio

  

Rugged, Australian Made commercial radios

UHF 450-520MHz WB/NB local mount 25 watt radio incorporates a rugged die-cast aluminium chassis which allows it to withstand constant vibration and extreme temperatures. The TX3820U provides a powerful 25 Watts of output power from a very small package.

For traditional DIN sized console mounting the MBD001 DIN adaptor kit allows the TX3820U to be easily installed or removed and has a flash' upgradeable microprocessor and flexible programming. The TX3820U has many calling options including CTCSS, DCS, MDC1200, DTMF and multi-tone selective calling which makes it an ideal network radio.
