The new digital signal processor (DSP) provides clear intelligible voice communications on analogue circuits through the digital removal of background noise and interference. The standard 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 easier listening.

The Barrett 4050's Secure Digital Voice option with variable vocoder rates of 600bps up to 2400bps and DES & AES digital encryption standards up to 256 bit deliver leading edge voice communication performance and security at all times.

The unique, easy to use 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 or 25 hops per second, using a 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.

The Barrett 4050 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.

Fully backwards compatible 2nd generation (2G) ALE based on MIL-STD-188-141B (JITC certified) and FED-STD-1045 is available. For superior fast link setup (FLSU), robust packet data and greater penetration on noisy channels, 3rd generation (3G) ALE based on STANAG 4538 is optionally available.

Multiple data waveform options are provided for in the Barrett 4050 including MIL-STD-188-110A/B (STANAG 4285, 4415, 4481, 4529, 4539), CLOVER 2500 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.

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

Control the Barrett 4050 transceiver 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 unprecedented access to all transceiver functionality on Windows and OSX computers, iPad and Android tablets.
