Description :

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 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 transceiver can be controlled from all major mobile and desktop platforms. The remote control app supports iOS, Android and Windows devices for wireless voice and radio control.

Barrett 4050 HF remote head and software interface

Software-Defined Architecture

The Barrett 4050's advanced Software-Defined architecture provides complete software control of RF modulation and bandwidths, providing unprecedented flexibility, reliability and ease of upgrade. Custom emissions and filter bandwidths of up to 16 kHz can be enabled with a simple software upgrade.

Digital and Secure Digital Voice

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 by the use of digital voice modules to the point where barely usable frequencies are made clear. Secure Digital Voice (SDV) allows users to encrypt (optional) 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.

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, and the effects of electrical interference by enhancing audio signals to provide clearer communication.

Frequency Hopping

The unique, easy to use Frequency Hopping (optional) requires no central synchronisation station, has no entry or late entry time delay and requires no handshaking. 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, the system provides excellent protection against electronic warfare (EW) attacks and can be operated for extended periods in the field without synchronisation.

Integrated GPS Interface

GPS interface supports connection of any NMEA 0183 external GPS receiver antenna for tracking applications. This interface enhances emergency call features and position information on all deployed equivalently equipped HF assets. Combined with Barrett's GPS Push tracking solution, can provide unrivalled aset tracking performance over HF.

Advanced Calling Features

The transceiver is fully interoperable with advanced digital selective calling systems commonly used by many peacekeeping and non-government organisations globally. The Barrett 4050 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.

Automatic Link Establishment

Backwards compatible 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.

Data Modems 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, CLOVER 3000 and the forthcoming CLOVER NG standard. 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.

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. Advanced Barrett 4050 to IP adaptors provide optional Ethernet connectivity to additional IP configurations.
