EXCEPTIONAL DIGITAL AND ANALOG VOICE CLARITY
Codan’s second generation Digital Voice (DV) technology provides a quantum leap in voice communications. It completely eliminates the hiss, crackle, pops, and multipath effects typical of HF. The vocoders used provide voice quality experience that is similar to cellular phones, and the modem technology ensures continued operation in degraded and fading channels. 

When analog SSB mode is needed, Envoy’s patented EasitalkTM DSP algorithm works to actively remove background noise and interfering ones. During transmission, Codan’s TalkPower feature dynamically compresses and shapes the frequency response of the voice signal to maximise transmit power and intelligibility. A syllabic squelch only opens the speaker mute when speech signals are present to eliminate background noise.

SOFTWARE-DEFINED ARCHITECTURE
Envoy uses latest-generation high-performance Digital Signal Processor (DSP), Field-Programmable Gate Array (FPGA) and microprocessor technology. This provides market-leading performance and future upgradability through software updates to install new capabilities and support evolving standards.

IP / ETHERNET / USB CONNECTIVITY
Envoy IP / Ethernet connectivity enables centralised programming, maintenance and operation of network connected stations. Envoy handsets and consoles include USB ports for convenient programming and maintenance via conventional USB cable connection or via attached memory stick.
