NX-3720-3820

 

UHF/VHF Multi-protocal Digital & Analog Mobile Radios

The adaptable mobile radio supports both NXDN® and DMR digital protocols as well as mixed digital & FM analog operation, enabling it to serve with distinction in a wide range of enterprise and operation critical applications. Designed with flexibility in mind, it’s packed with convenient features like Bluetooth® for hands-free operation and built-in GPS. And providing greater freedom of installation, the radio’s front panel can be used as a remote control head (this requires an optional upgrade, to be available in the future). Additionally, for expansion capability a software license certification system facilitates extensive customization.

Features:

 

  • Multi-protocol digital radio: Designed to operate NXDN or DMR digital, and FM analog protocols
  • NXDN® Conventional and Type-C & Gen2 Trunking
  • DMR Tier II & Site Roaming
  • Mixed Digital & FM Analog Operation allows gradual migration at your own pace
