Kenwood NX-3220 / NX-3320 / NX-3420

Enterprise fleets running across wide areas need more than a conventional repeater can offer. NXDN Gen2 trunking connects up to 1,000 sites and 24 networks, while DMR Tier III adds slot-efficient trunking with auto site roaming. Choosing between them used to mean choosing a radio platform. The NX-3000 series carries both protocols, plus FM analog, so the network decision doesn't lock you into a hardware decision.

The NX-3220 covers VHF at 136-174 MHz, the NX-3320 covers UHF across a full 120 MHz range at 400-520 MHz, and the NX-3420 handles 700/800 MHz. All deliver 5 W on VHF/UHF, with 260 channels and 128 zones standard, expandable to 1,000 channels via software license. Built-in GPS transmits positional data compatible with Kenwood KAS-20 fleet tracking software. Bluetooth 3.0 supports headset and serial port profiles for hands-free operation and accessory connectivity. Standard DES-56 encryption is included; optional AES-256 is field-upgradable.

The IP67 rating is genuine: 30 minutes at 1 meter depth when equipped with the 2-pin connector cover, meeting MIL-STD-810 C through G. An embedded accelerometer and tilt sensor trigger man-down, stationary, and motion detection alerts, with Lone Worker adding a timer-based auto-emergency backup. Active Noise Reduction provides single-microphone noise suppression equivalent to dual-mic systems. The 7-color top-panel LED is individually configurable per channel, and the dot-matrix LCD handles 4-line basic and 5-line text message frames.
