BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Introduction
The Barrett 4050 Transceiver is an SDR based HF SSB Transceiver with a fre-
quency range of 1.6 to 30 MHz. The Barrett 4050 is designed using the latest
technology enabling a physically small package with a full feature complement.
Designed to operate in the most arduous environments, as encountered in off-
road vehicles, vessels and aircraft, the Barrett 4050 will provide many years of
HIÀFLHQWDQGWURXEOHIUHHVHUYLFH
The Barrett 4050 supports features such as Selective Call (Selcall), direct dial
WHOHSKRQHFRQQHFWLRQWREDVHVWDWLRQVÀWWHGZLWKWHOHSKRQHLQWHUFRQQHFW
systems (Telcall), GPS location, ALE (Automatic Link Establishment), frequency
hopping, data transmission and remote diagnostics. These features make the
Barrett 4050 HF Transceiver one of the most economical and versatile HF Trans-
ceiver available today.
The Barrett 4050 Transceiver caters for 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

applications.
The Barrett 4050 Transceiver can be controlled from all major mobile and
desktop platforms. The Barrett 4050 handset app supports iOS, Android and
Windows devices for wireless voice and radio control. Full remote control is
available via the Barrett 4050 Virtual Control Head app, providing unprece-
dented access to all transceiver functionality on Windows and OSX computers,
iPad and Android tablets.
Operated from either 12 volt (13.8 V) DC or 24 V DC supplies, the transmitter is
rated at 125 or 150 watt PEP respectively in voice mode and is protected from
over-voltage or reverse-voltage application.

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 products which include antennas, power
supplies, vehicle tracking packages and HF modems, the Barrett 4050 HF Trans-
ceiver becomes a powerful tool, providing solutions to many long distance
communication requirements.
