Barrett Communications Barrett 4050 HF SDR software-defined radio

Barrett Communications has announced the Barrett 4050 HF SDR, its HF transceiver which includes software-defined radio technology. The product features a 24-bit colour touch-screen interface and is designed for use by law enforcement and security organisations, as well as NGOs and commercial businesses.

The device’s adapter ensures simple integration with existing networks, while for vehicle and remote installations, its wireless access point (built into the control head) allows mobile cellular handsets and tablets to connect directly to the transceiver. Advanced network configurations are supported by the Barrett 4050 Breakout Box (BoB), which also provides Wi-Fi and ethernet connectivity.

The product’s Secure Digital Voice option, with variable vocoder rates of 600–2400 bps and DES and AES digital encryption standards up to 256-bit, delivers continual good communication performance and security. The digital signal processor (DSP) provides clear, intelligible voice communications on analog circuits through the digital removal of interference. The standard DSP noise reduction system provides good voice quality by reducing radio-frequency interference and the effects of electrical interference by enhancing audio signals to provide easier listening.

Multiple data waveform options are provided, including MIL-STD-188-110A/B (STANAG 4285, 4415, 4481, 4529, 4539), CLOVER 2500 and the forthcoming CLOVER NG standard. Multiple languages are available, including Arabic, Chinese, English, French, Russian and Spanish, with additional languages being added progressively.
