What a digital voice vocoder can offer

4050 SDR and Base station setup

Whether you’re on a tactical operation or a humanitarian mission, you need to be confident that your team can understand each and every word you say. A digital voice vocoder, like the one on the new 4050 HF SDR transceiver, makes just that kind of consistency possible.

The advantage of digital voice

With Barrett’s digital voice, you get telephone-quality communications and a nearly unmatched level of consistency. The system digitises voice signals with a vocoder and transmits then through a data waveform. The waveform is then decoded at the receiver with a voice message that is clear, crisp and secure.

To ensure consistent transmission and prevent variations in path quality, the vocoder uses data rates ranging from 2400 bits per second (bps) down to 600 bps. It also employs Digital and Advanced Encryption Standards (DES and AES) up to 256 bit. Data waveforms use throughput rates that reach beyond 19200 bps.

A clear understanding of communications by all parties is essential, whether on the battlefield or in the aid tent. The digital voice feature on the 4050 HF SDR transceiver ensures crisp communication each and every time.

Moving forward with the 4050 HF SDR transceiver

Advances in digital voice technology aren’t the only reasons the Barrett 4050 HF SDR transceiver represents the pinnacle of communications equipment. From secure email, data transfer and telephone connectivity to an easy-to-use layout, this transceiver can get the job done in nearly any kind of mission.

Some of the other key features of Barrett’s newest generation of transceiver include:

• High-resolution touch screen control
• Advanced software-defined architecture
• A multi-language menu
• Integrated GPS interface
• Automatic link establishment
• IP network connectivity with other devices
