Kenwood NX-3720HGK/3820HGK

VHF/UHF Digital Transceiver Multi-Protocol Digital and Analog Portable Radios

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.

  • Active Noise Reduction (ANR) for Supressing Ambient Noise

    KENWOOD’s advanced ANR technology performs complicated noise reduction, which normally requires two microphones for processing, using single microphone.

  • Built-In Bluetooth

    Hands-free operation is vital for many NX-3000 users. The radios’ built-in Bluetooth® module is compatible with Headset and Serial Port Profiles (ver. 3.0) and keeps your hands free.

  • Encryption Equipped

    Secure communications are an essential requirement, especially for public safety applications. NX-3000 radios are equipped with 56-bit key Data Encryption Standard (DES) encryption. For even higher protection the radios can support 256-bit Advanced Encryption Standard (AES) encryption with optional module.

  • Full Dot LCD & Backlit Color in White

    Full Dots Matrix (256(W) x 82(H)dots, Monochrome) can display 4-Line Basic Frame and 4-Line Text Message Frame.

  • GPS to Transit Your Position

    Featuring an integrated GPS module and antenna, NX-3000 portable radios can transmit positional data, enabling effective management when used with tracking applications like KAS-20 software. Mobile models can support GPS with the optional KRA-40G.

  • MIL-STD Environmental and Ingress Protection Standards

    while the mobile radios comply with IP54/55 dust/water ingress protection standards.

  • Sensors For User Safety

    Man-down Detection, Stationary Detection, or Motion Detection will be automatically engaged when the embedded acceleration and tilt sensors detect unusual behavior. Lone Worker function automatically places the radio in Emergency Mode if it is not operated for a certain period of time. The bright orange Emergency Button is located at the top (portables) or front (mobiles) of the radio for high visibility and instant access when needed.

  • Tough and Robust

    Stringent test to develop tough radio withstanding harsh operational conditions.
