The Barrett 4050 HF SDR transceiver is the centrepiece of the
Barrett range of HF communications equipment. It combines
Software-Defined Radio technology with the intuitive "ease
of use" that has become synonymous with the Barrett name.
When teamed with other Barrett HF products, the versatile
Barrett 4050 transceiver provides secure email, data transfer
and telephone connectivity within a HF network and
outwards to international telephone and internet networks.

The Barrett 4050 transceivercanbe controlled from all major 
mobile and desktop platforms. The Barrett 4050 remote control
app supports iOS, Android and Windows devices for wireless 
voice and radio control.

Flexible Configuration Options
The transceiver mounts easily to the Barrett 4022 power supply 
for base station operation or the front panel can be removed 
for installation in a vehicle.

The fully featured Barrett 4050 control handset provides
streamlined radio control particularly in vehicle and marine
installations. The handset can be used as the primary control
interface, completely replacing the standard 4050 front control 
panel or as a secondary interface in conjunction with the 
standard control panel. IP/WiFi connectivity can be achieved 
with the optional USB Interface.

Advanced Calling Features
The Barrett 4050 transceiver is fully interoperable with advanced 
digital selective calling systems commonly used by many 
peacekeeping and non-government organisations globally. 
2nd generation (2G) ALE, based on MIL-STD-188-141B (JITC certified) 
and FED-STD-1045, is available as an option for automatic 
point-to-point and/or multipoint calling including telephone 
interconnect, AMD text messaging and GPS position. For superior 
fast link setup (FLSU), robust packet data and greater penetration 
on noisy channels, 3rd generation (3G) ALE based on STANAG 4538 
is also available.

Multi-Language Menu
Change the Barrett 4050 language setting at the touch of a button. 
Each radio ships with multiple language menus including English, 
French, Spanish, Arabic, Russian, Turkish and Chinese.

Software-Defined Architecture
The Barrett 4050 transceiver's advanced Software-Defined
architecture provides complete software control of RF
modulation and bandwidths, providing unprecedented
flexibility and reliability with ease of upgrade. Custom
emissions and filter bandwidths of up to 24 kHz (wideband
HF option) can be enabled with a simple swipe of the

High Resolution Touch Screen Control
Access to the most intuitive HF Radio interface on the market
is via a super bright high definition 24-bit colour touchscreen
providing maximum view ability under all lighting

The 4050 SDR software has four separate theme modes for use in different 
ambient light conditions. The screen can also be turned into landscape format 
via the user interface, if required.

Digital and Secure Digital Voice (optional)
Digital Voice (DV) can improve the reliability of
communications over noisy channels where reception of
analogue voice can be very poor. Secure Digital Voice (SDV)
allows users to encrypt their communications over HF radio
providing a secure HF network. Barrett offer two SDV
encryption standards. A non-export controlled DES 56
vocoder with rates of 700, 1200 and 2400bps or an export
controlled AES 256 vocoder with rates of 600, 1200 and
2400bps. Both deliver cutting edge voice communication
performance and security at all times.

IP Network Connectivity
Built into the 4050 control head, the wireless acesspoint
allows mobile cellular handsets, tablets and desktop PCs to
connect directly to the transceiver over Wi-Fi using the
optional Wi-Fi adaptor. Ethernet connectivity to additional IP
configurations is provided for by way of a standard RJ45
ethernet socket on the rear of the 4050ip transceiver.

Frequency Hopping (optional)
The frequency hopping* option requires no central
synchronisation station, has no entry or late entry time delay
and requires no handshaking. Available hopping rates of 5,
15 & 25 hops per second and can be operated for extended
periods in the field without synchronisation. 
* Subject to export controls


Data Modem Capability
Multiple data waveform options are provided in the Barrett
4050 including MIL-STD-188-110A/B (STANAG 4285, 4415,
4481, 4529, 4539) & CLOVER 2500. Combined with Barrett's
latest Digital Transmission software and intuitive user
interface, these waveforms provide unparalleled
performance with "throughput" rates up to and in excess of
19200 bps.

Enhanced DSP Noise Reduction
The digital signal processor (DSP) provides clear intelligible
voice communications on analogue circuits through the
digital removal of background noise and interference. The
DSP noise reduction system provides outstanding voice
quality by reducing radio frequency interference.
