The Barrett PRC-4090 HF SDR Transceiver is the 
centerpiece of the Barrett range of tactical 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 PRC-4090 transceiver provides
secure email, data transfer and telephone connectivity
within a HF network and outwards to international
telephone and internet networks.

The Barrett PRC-4090 transceiver can be controlled 
from all major mobile and desktop platforms including
iOS, Android and Windows devices for wireless voice
and radio control via the 4000 series HF remote control
app.

Digital Voice 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. Voice can be
improved markedly to the point where barely usable
frequencies can be made clear. 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.

Advanced Frequency Hopping
(optional)
Available hopping rates of 5 or 25 hops per second,
the use of an 8 digit hopping encryption key, with
a user selectable hopping bandwidth to suit a
variety of antenna types means that the system
provides excellent protection against electronic
warfare (EW) attacks and can be operated for 
extended periods in the field without
synchronisation.

Integrated GPS
Barrett's integrated GPS is built into the handset.
The integrated GPS enhances emergency call features
and position information on all deployed
equivalently equipped HF assets. Combined with
Barrett's GPS Push tracking solution, Barrett can
provide unrivaled asset tracking performance over
HF radio.

Data Modem Compatibility
Multiple data waveform options are provided in
the Barrett PRC-4090 including MIL-STD-188-110A/B
(STANAG 4285, 4415, 4481, 4529, 4539), 3G Packet
Data (STANAG 4538), CLOVER 2500 and CLOVER 3000.
Combined with Barrett's latest data transmission
software and intuitive user interface, these
waveforms provide unparalleled performance with
"throughput" rates up to and in excess of 19,200 bps.

IP Network Connectivity
Built into the PRC-4090 System Docking Station,
the Ethernet accesspoint allows the HF network to
connect directly to PCs. This allows the HF network
to integrate with Barrett's tracking and data 
options.

Advanced Calling Features
The Barrett PRC-4090 transceiver provides four and
six digit selective call features, including
telephone interconnect, SMS text, GPS tracking,
status calling, point to point and/or multipoint
secure call and remote transceiver disable
capabilities.

2G & 3G ALE (optional)
Backwards compatible 2nd generation (2G) Automatic
Link Establishment (ALE), based on MIL-STD-188-141B
(JITC certified) and FED-STD-1045, is available as
an option for automatic point-topoint 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.

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. Automatic antenna tuner
Whips and un-tuned wire antennas are accommodated
with the inbuilt, fully automatic antenna tuner.
Various lightweight broadband and tunable tactical
antennas are available.

The Barrett PRC-4090 HF Tactical Manpack Package is
ideal for extended portable field operations providing
the tactical user with effective, secure and
comprehensive communications with remotely sited
command locations. The HF Tactical Manpack Package
includes all necessary antennas, smart battery
and backpack carrying system.

The Barrett PRC-4090 HF Tactical Mobile Package provides
a convenient rapid docking system and transmitter power
amplification to 125 W PEP. With options for either 12 V
d.c. or 24 V d.c. power supply and the flexibility of
dismounted use of the PRC-4090 transceiver when not in
the vehicle (additional accessories may be required),
the PRC-4090 HF Tactical Mobile Package can be installed
in a wide range of vehicle types with antenna options to
suit.

The Barrett PRC-4090 HF Tactical Base Package, like the
PRC-4090 mobile package includes the system docking
station. The PRC-4022 AC Power Supply provides 24V
d.c. which increases the RF output of the PRC-4090
transceiver to 150 W PEP. The HF tactical base package
can be installed in a number of temporary base and
fixed command configurations powered by a variety of
a.c. and d.c. power sources. A range of antenna options
are available to suit different installation
configurations.
