Codan Digital Voice for the Envoy HF smart radio

Codan Radio Communications has announced the launch of its second-generation Digital Voice technology for the Envoy HF smart radio. Digital Voice provides voice clarity on the HF band, providing an experience that is similar to mobile phones and ensures continued operation in degraded and fading HF channels.

Codan’s voice coding technology provides greater clarity of voice over a range of rates from 2400 bps to 600 bps, proving optimum performance in varying conditions. The technology supports STANAG 4591 (MELPe), MIL-STD-188-141B ALE and AES-256 encryption, while including a propriety vocoder mode which is said to provide superior voice performance compared to MELPe.

Additional Envoy enhancements include: GPS navigation, now using waypoints for measuring distances between radios and set locations; and its user interface, with a new missed-call feature and the ability to group contacts for better management of communications channels and large networks. The Envoy now also supports the connection of external audio recording devices for safety, traceability and auditing requirements. Standard features include a colour screen, IP capability and multilanguage support.
