IMPORTANT INFORMATION

FOR AVIONICS INSTALLATION FACILITIES

The NPX138 is supplied without TSO certification, as no such standard presently exists for airborne VHF/FM radio transceivers. This equipment provides what is considered as “supplemental” communications, and can be installed in an aircraft on a “Non interference” basis. Installation should be performed using standard procedures applicable to aircraft radio installation, to ensure that the newly installed equipment does not interfere with any other equipment in the aircraft.

This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.

SM41 Rev. 4.00 NPX138 Panel Mount Radio Manual

Section 1.0 Description

1.1 Introduction

This manual contains description, installation, operation and maintenance information on the NPX138 series of panel mount FM transceivers, serial numbers 1238 and subsequent.

The NPX138 incorporates NAT’s proven user-friendly operating system with on-line help, making it easy to program and use. The small size makes this radio ideal for airframes where size and weight are a factor.

1.2 Purpose of Equipment

The NPX138 panel mount FM transceiver is a stand-alone radio designed for the single mission user. It provides all the features needed to satisfy FM communications within the VHF-FM high band.

1.3 Features

The NPX138 covers a frequency range of 138.000 MHz to 173.995 MHz in 5.0/6.25 kHz increments. Each of the 100 available channels can include a receive frequency and CTCSS tone, transmit frequency and CTCSS tone, and an alpha/numeric identifier.

A SCAN function allows scanning of selected channels. Transmit power of either 1 watt or 10 watts is selectable from the front of the NPX138. Simplex and semi-duplex operations are available. An optional guard receiver is available with some models.

DTMF encoding and direct keyboard entry can be effected by the use of the DTE12, an accessory available from NAT.

Conveniently located beside the display are separate main volume, guard volume and transmit select switches. Easily identified along the bottom of the front panel are squelch test, channel up/down and display brightness controls. The aircraft dimmer buss provides control for the panel lighting.

Depending on model selected the NPX138 can provide wideband (± 5.0 kHz Rated System Deviation) and/or narrowband (± 2.5 kHz Rated System Deviation) by channel. Compensation circuitry ensures that the average receive audio level remains constant when the mode changes.
