The NX-340U16P 16 channel 5-Watt portable radios operate in either analog FM or NXDN digital modes, offering a cost-effective way to migrate smoothly from legacy systems while discovering the benefits of advanced digital technology - including increased effective coverage area, low noise for superior clarity, and inherent secured voice. All this comes in a tough, compact radio that is easy to operate, delivers high-powered audio, and ensures round-the-clock reliability. Effectively two radios in one - analog and digital - operating on 12.5kHz in analog zones, and on 6.25kHz NXDN in digital zones. A PF key can be used to switch between zones. The radio employs NXDN, an FDMA digital air interface with voice coding technology, unique filtering and a 4-level FSK modulation technique with low bit error rate (BER) to improve reception in fringe areas. Users can program a ProTalk to any of the pre-stored frequencies, QT/DQT analog codes, RAN digital codes, assuring compatibility with other brands. This 16-channel model has 99 pre-stored frequencies with 39 Qt. tones and 168 DQT codes in analog mode and 64 RAN codes in digital mode. For licensing information, please contact the FCC via their web page. To help 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. The wireless cloning feature simplifies the setting up of multiple ProTalk radios for identical functions.
