Barrett 4050 HF SDR transceiver
The Barrett 4050 HF SDR transceiver is the centrepiece of Barrett’s HF communications product range. It combines software-defined radio technology with the intuitive ease of use that has become synonymous with the Barrett name. Together with other Barrett HF products, the versatile 4050 provides secure email, data and telephone communications within an HF network, as well as connections to international telephone networks and the Internet.
The Barrett 4050 can be 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.
The advanced software-defined architecture of the 4050 gives full software control of RF modulation and bandwidth, providing exceptional flexibility, reliability and ease of upgrade.
Custom emissions and filter bandwidths of up to 16 kHz can be enabled with a simple software upgrade.
The most advanced, intuitive HF radio interface on the market is accessed through an ultra-bright, high-definition 24-bit colour touchscreen that gives maximum visibility in any lighting conditions.
Digital voice (DV) improves communication reliability on noisy channels where analogue voice reception can be very poor. Digital voice can improve speech so markedly that frequencies that were barely usable become clear.
Secure Digital Voice (SDV) lets users encrypt their HF radio traffic, creating a secure HF network. Barrett offers two SDV encryption standards: a non-export-controlled DES-56 vocoder at 700, 1200 and 2400 bps, or an export-controlled AES-256 vocoder at 600, 1200 and 2400 bps. Both deliver the highest performance and voice security at all times.
The digital signal processor (DSP) provides clear, intelligible voice over analogue circuits by digitally removing background noise and interference. DSP noise reduction delivers superior voice quality by reducing RF interference and electrical noise while enhancing the audio signal for clearer communications.
Change the language of the Barrett 4050 at the touch of a button. Every radio ships with multi-language menus, including English, French, Spanish, Arabic, Russian, Turkish and Chinese.
The unique, easy-to-use frequency hopping option* requires no master station for synchronisation, has no time-of-day entry or late-entry delay, and needs no handshaking. With hop rates of 5 or 25 hops per second, an 8-digit hopping encryption key and a user-configurable hopping bandwidth to suit different antenna types, the system provides excellent protection against electronic warfare (EW) attacks and can operate in the field for long periods without resynchronisation.
The Barrett GPS interface accepts any external NMEA 0183 GPS receiver for tracking applications. It extends emergency calling and position reporting to all equivalently equipped HF stations in the network. Combined with Barrett’s upcoming GPS Push tracking solution, Barrett delivers outstanding HF tracking performance. The Barrett 4050 is fully compatible with the advanced selective calling systems commonly used by peacekeeping and non-governmental organisations around the world.
The Barrett 4050 provides four- and six-digit selective calling (Selcall) functions, including telephone interconnect, SMS text messaging, GPS tracking, status calls, point-to-point and/or point-to-multipoint secure calls, and remote transceiver disable.
Backward-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 point-to-multipoint communications, including telephone interconnect, AMD text messaging and GPS position reporting. For superior Fast Link Set-Up (FLSU), robust packet data and better penetration of noisy channels, 3rd-generation (3G) ALE based on STANAG 4538 is also available.
The Barrett 4050 offers several data waveform options, 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 messaging software and intuitive user interface, these waveforms provide exceptional performance with throughput of up to 19,200 bps and beyond.
A wireless access point built into the 4050 control head lets mobile phones, tablets and desktop PCs connect directly to the transceiver over Wi-Fi using an optional Wi-Fi adapter. Advanced Barrett 4050 IP adapters provide Ethernet connectivity for additional IP configurations.
The Barrett two-port antenna switch allows two antennas and automatic antenna tuning units (ATUs) to be connected to the 4050 HF transceiver.
