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 36mm-diameter speaker delivers up to 1 watt audio output, providing undeniably clearer and crisper audio.
ULTIMATE PERFORMANCE
RF output power is 5W for both VHF (NX-240) and UHF (NX-340). Additionally, the UHF frequency coverage on the NX-340 is 70 MHz.
ERGONOMIC DESIGN
The slim contours and ergonomic design of the NX-240/340 make it comfortable to hold, while the dimples on both sides ensure a firm grip.
32 CHANNELS / 2 ZONES
The NX-240/340 can be used with two conventional zones, offering up to 16 channels per zone.
SWITCHABLE DIGITAL AND ANALOG DUAL MODES
The NX-240/340 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.
6.25/12.5 kHz NXDN DIGITAL CHANNEL
Digital communications are more spectrum efficient and offer wider area coverage than analog.
NXDN 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-240/340 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 small-scale digital trunking system.
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.
GPS CONNECTIVITY
The optional KMC-48GPS Speaker Microphone will enable GPS tracking applications to work with the NX-240/340. GPS data can be transmitted at programmed timing, or upon receiving a request.
