NPX Series General Description:
NAT's family of self contained panel mount FM transceivers are designed as stand-alone, mission specific radios. Their lightweight compact design is perfect for the space and weight restriction of helicopters and light fixed wing aircraft. Incorporating NAT's proven, user friendly Tac/Com II__operating system, the NPX series is simple to program and easy to use. Main volume control and a scan select switch are conveniently located beside the display. The squelch test, channel up/down, and display brightness controls are easily identified along the bottom of the panel. A separate guard volume and guard transmit select switch is provided. With no complex patterns or codes to memorize, the NPX's straight forward controls and online ""Help"" screens insure intuitive operation. PC software is available for fast, convenient programming of complete channel information. The capability to upload and download NPX channels allows users to store multiple sets of operating frequencies for quick transitions between contract assignments. These compact radios incorporate solid chassis construction, user friendly controls and are tested to stringent aircraft environmental standards. Whether the mission is forestry, law enforcement, business communications or other applications, the NPX family of radios will satisfy the most demanding operational needs.
NPX138N:
This USFS compliant radio was specifically designed to fulfill contract required functionality. The synthesized frequency-agile transceiver allows easy access to all pre-programmed channels and the ability to modify or add channels on the fly.
At less than 2"" high and 3 lb., NAT's self-contained panel mount NPX138 radios are designed as stand-alone units for the single mission user. The lightweight state-of-the-art compact design is perfect for the space and weight restricted environment of a helicopter or light fixed-wing aircraft.
Each of the 100 memory channels available can store a receive frequency with CTCSS tone, a transmit frequency with CTCSS tone, scan function and an alpha-numeric identifier on a 32 character LED display. Transmit power of 1 or 10 watts is easily selectable from the front of the NPX.
The optional synthesized two channel guard receiver allows front panel tuning of user frequencies, ensuring communication integrity during complex flight operations. Each individual channel is operator selectable for wide (5 kHz deviation) and narrow band (2.5 kHz deviation) operation. DTMF encoding and direct keyboard programming can be added using NAT's DTE12.
Panel lighting is available in either 28, 14 or 5 VDC controlled through the aircraft dimmer bus. NVG compatible lighting is optional.
