Introduction
The Barrett 950 transceiver is a sophisticated yet easy to operate, 450 channel HF SSB
transceiver with a frequency range of 1.6 to 30 MHz. Designed to operate in the most arduous
environments, as encountered in off road vehicles, vessels and aircraft, the Barrett 950 will
provide many years of efficient and trouble free service.
The Barrett 950 supports features such as selective call (Selcall), direct dial telephone
connection to base stations fitted with telephone interconnect systems (Telcall) , GPS location,
ALE (Automatic Link Establishment), data transmission and remote diagnostics. These
features make the Barrett 950 HF transceiver one of the most economical and versatile HF
transceiver available today.
The Barrett 950 transceiver, has catered for the increased use of HF data transmission for
Internet email access and point to point data applications, by providing a comprehensive data
modem interface port, high speed transmit to receive switching, a high stability frequency
standard option and an efficient inbuilt cooling system option.
The Barrett 950 transceiver is available in a local (desktop) configuration for base station
applications or in a remote control (trunk mount) configuration for mobile applications. A
combination of both of these configurations allows the 950 to be controlled from two positions,
simultaneously if required.
Operating from 12 volt (13.8 VDC) DC supplies, the transmitter is rated at 125 watt PEP in voice
mode and is protected from over-voltage or reverse voltage application.
All 450 channels are available to be field or workshop programmable. Auxiliary features such as
selcall, telcall, scanning, mute status, alarm system etc. can be individually enabled or disabled
for every channel as required to suit your operation.
Teamed with other matching Barrett 900 series products which include antennas, power
supplies, vehicle tracking packages and HF modems , the Barrett 950 HF transceiver becomes
a powerful tool, providing solutions to many long distance communication requirements.

Operation
Front panel description
The Barrett 950 transceiver is turned on by rotating this control clockwise. Turn the control
clockwise until volume is set to correct level.
The microphone supplied with the Barrett 950 is inserted here.
This group of LED's indicates the mode currently in use. When receiving the green Rx LED
is illuminated, when transmitting the red Tx LED is illuminated. The operating mode of the
transceiver is indicated by the remaining LED's. (i.e. USB, LSB, AM).
