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.

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-240V) and UHF (NX-340U). Additionally, the UHF frequency coverage on the NX-340U is 70MHz.

NXDN® DIGITAL AIR INTERFACE

 

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.

NXDN® DIGITAL AIR INTERFACE

 

The NX-240/340 can be used with two conventional zones, offering up to 16 channels per zone.

NXDN® DIGITAL AIR INTERFACE

 

The NX-240/340 is effectively two radios in one – analog and digital – operating on 12.5kHz/25kHz in analog zones, and on 6.25kHz/12kHz NXDN® in digital zones (Ver.02 only). For convenience, a PF key can be used to switch between zones.

NXDN® DIGITAL AIR INTERFACE

 

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

NXDN® DIGITAL AIR INTERFACE

 

Compatible with NEXEDGE® Digital Conventional Mode, this radio offers 64 RAN (Radio Access Numbers) and individual & conference group calling to ensure expeditious communications.

NXDN® DIGITAL AIR INTERFACE

 

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.

NXDN® DIGITAL AIR INTERFACE

 

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.
