Description
It’s true that analogue radios are still playing a role in mobile communications today. But the future is unquestionably digital, and the new NEXEDGE® NX-740H/840H demonstrates why, offering increased effective coverage area, low noise for superior clarity, and inherently secure voice communications. As you would expect from KENWOOD, intuitive operation, high-powered performance, and round-the-clock reliability come as standard. But there’s more. This mobile radio has a dual personality: it operates in both analog FM and NXDN® digital modes, enabling smooth migration from legacy systems.

NXDN® DIGITAL AIR INTERFACENEXEDGE® radios employ NXDN®, an FDMA digital air interface with AMBE+2™ voice coding technology, unique filtering and a 4-level FSK modulation technique with low bit error rate (BER) even at weak RF signal strengths.
SWITCHABLE DIGITAL AND ANALOG DUAL MODES
The NX-740/840 Series is effectively two radios in one – analogue and digital – operating on 12.5 kHz in analogue zones, and on 6.25 kHz NXDN® in digital zones.* For convenience, a PF key can be used to switch between zones. *12.5 kHz in digital zones and 25 kHz in analog zones are not covered.
EXTERNAL D-SUB 15-PIN INTERFACE
The radio’s D-Sub 15-pin terminal can be used to connect peripherals, enabling Ignition Sense, External Switch, Horn Alert, etc. Molex interface compatibility is provided by the optional KCT-60 cable.
ENHANCED AUDIO QUALITY
AMBE+2™ VOCODER technology accurately replicates natural human speech nuances for superior voice quality, even in noisy environments. Additionally, the powerful oval speaker delivers up to 4 watt (4Ω impedance) audio output, providing undeniably clearer and crisper audio.
6.25 kHz NXDN® DIGITAL CHANNEL
Digital communications are more spectrumefficient and offer wider area coverage than analogue.
ULTIMATE PERFORMANCE
Maximum RF output power is 50W on the NX-740H VHF model, 45W on the NX-840H UHF model. Additionally, the UHF frequency coverage on the NX-840 Series is 70 MHz.
NXDN® DIGITAL CONVENTIONAL
Compatible with NEXEDGE® Digital Conventional Mode, this radio offers 64 RAN (Radio Access Numbers) and individual & conference group calling to ensure expeditious communications.
32 CHANNELS / 2 ZONES
This radio can be used with two conventional zones, offering up to 16 channels per zone.
GPS FEATURE
Connecting a GPS unit to the NX-740/840 Series enables you to transmit accurate vehicle location (GPS) data to the central base station for fleet management purpose.
