The NPX138N Series Narrowband VHF-FM Panel-Mount Transceiver was specifically designed to fulfill USFS 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. 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 as a stand-alone unit for the single mission user.
Version NPX138N900 has a 5VDC night vision goggle (NVG) compatible lighting.
