Kenwood NX-840 Mobile Vehicle Station

It’s true that analog radios are still playing a role in mobile communications. But the future is unquestionably digital, and the new NEXEDGE NX-740HV/840HU demonstrates why, offering increased effective coverage area, low noise for superior clarity, and inherent secured voice. 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.The Kenwood NX-840 radio repeater mobile vehicle station is a high-performance communication device designed to meet the needs of professionals in various industries. With its NXDN digital air interface, this mobile station enables clear and reliable communication, ensuring that important messages are delivered accurately and without interference.

One of the standout features of the NX-840 radio repeater is its switchable digital and analog dual modes. This allows users to seamlessly transition between digital and analog modes, making it compatible with existing analog systems while also providing the advantages of digital communication. This flexibility ensures that users can easily adapt to different communication environments without the need for additional equipment.

Equipped with a built-in GPS function, the NX-840 walkie talkie enables precise positioning and tracking of vehicles. This feature is particularly useful for fleet management, emergency services, and transportation industries, allowing for efficient dispatching, improved response times, and enhanced safety.

In addition to its core features, the Kenwood NX-840 offers a range of other functions to enhance usability and convenience. These include programmable function keys, a large color display for easy navigation and information viewing, and a durable construction that can withstand harsh working conditions.

Overall, the Kenwood NX-840 mobile vehicle station is a reliable and versatile communication solution for professionals who require efficient and secure communication. With its NXDN digital air interface, switchable digital and analog dual modes, GPS function, and other advanced features, this mobile station ensures seamless communication, improved productivity, and enhanced safety in various industries.

NXDN DIGITAL AIR INTERFACE

NEXEDGE 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.

ENHANCED AUDIO QUALITY

AMBE+2 VOCODER technology accurately replicates natural human speech nuances for superior voice quality, even at highway speeds. Additionally, the powerful 2-1/4"x 1-3/8" oval speaker delivers up to 4W (4Ω impedance) audio output, providing undeniably clearer and crisper audio.

ULTIMATE PERFORMANCE

Maximum RF output power is 50W on the NX-740HV VHF model, 45W on the NX-840HU UHF model. Additionally, the UHF frequency coverage on the NX-840HU is 70 MHz.

HIGH SECURITY

Confidentiality in radio communications is a KENWOOD priority, and helping to maintain a high level of security in analog mode is a 16-code voice inversion scrambler, while robust NXDN encryption is available in digital mode.

32 CHANNELS / 2 ZONES

This radio can be used with two conventional zones, offering up to 16 channels per zone.

SWITCHABLE DIGITAL AND ANALOG DUAL MODES

The NX-740HV/840HU is effectively two radios in one – analog and digital – operating on 12.5/ 25* kHz in analog zones, and on 6.25/12.5 kHz NXDN in digital zones. For convenience, a PF key can be used to switch between zones.

*25 kHz is not included in the models sold in the USA or US territories.

6.25 & 12.5 kHz NXDN DIGITAL CHANNELS

Digital communications are more spectrum-efficient and offer wider area coverage than analog.

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.

NXDN TYPE-D DIGITAL TRUNKING*

The NX-740HV/840HU supports the NXDN Type-D digital trunking protocol.* With this architecture, also known as distributed or decentralized trunking, all channels can operate as traffic channels without the need for a dedicated control channel. This makes it possible to develop an efficient and reliable yet affordable trunking system. Type-D trunking is thus suitable for users considering migration to a smallscale digital trunking system.

GPS FEATURE

Connecting a GPS unit to the NX-740HV/840HU enables you to transmit accurate vehicle location (GPS) data to the central base station for fleet management purpose.

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.
