Kenwood NX3720/3820 Mobile

The NX-3720E is a VHF digital analogue hybrid mobile radio from Kenwood. A multi-protocol digital radio, the NX-3720E is designed to operate under NXDN, DMR or analogue protocols allowing for it to be used in a transition stage of radio systems. Built to military standards (MIL-STD-810 C/D/E/F/G) the radio is rugged and reliable, continuing to operate in weather conditions from as low as -30’C through to 50’C.

Description

Kenwood NX-3720 is a VHF mobile Two-Way Radio that can be programmed in analogue, NXDN or DMR (either or, not both). Available with GPS (NX-3720GE) or without GPS (NX-3720E); select when ordering. It’s important to note that a microphone is NOT included with the radio and the microphone option must be selected if required.

This 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 future). Additionally, for expansion capability a software license certification system facilitates extensive customization.
