The NX-340UP is effectively two radios in one – analog and digital – operating on 12.5kHz in analog zones, and on 6.25kHz NXDN® in digital zones. For convenience, a PF key can be used to switch between zones.


NX-340UP 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. As RF signal strength weakens with distance, analog reception becomes increasingly noisy and intermittent. NXDN®’s low BER improves reception in fringe areas, thereby “effectively” increasing coverage as much as 20% over analog.


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.


Users can program a ProTalk® to any of the pre-stored frequencies, QT/DQT analog codes, RAN digital codes, thus assuring compatibility with other brands. The ProTalk® digital UHF (NX-340UP) 16-channel model has 99 pre-stored frequencies. It also has 39 QT tones and 168 DQT codes in analog mode and 64 RAN codes in digital mode.


Both PF Keys can be programmed for any of the many functions available, permitting customization to suit your specific requirements.


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 with 32,767 selectable digital modes.

Site Search

Move between multiple sites seamlessly by using the Site Search functionality on your EVX-530 series radio. Manually or automatically initiate Site Search to identify the signal of the closest site with the strongest signal strength. The EVX-530 portable will dynamically change its preprogrammed home site to the site with the strongest signal in range. Great for operations with multiple locations or multiple floor buildings.
