 ENVOY X2 model
Codan's Envoy HF Radio delivers dependable, clear, trouble-free voice, messaging and data communications, without dependence on existing infrastructure. With second generation Digital Voice technology, Envoy provides outstanding voice clarity in conditions where competing HF radios fail. Codan's second generation Digital Voice (DV) technology provides a quantum leap in voice communications. It significantly reduces 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 Easitalk DSP algorithm works to actively remove background noise and interfering tones. 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.
Envoy uses latest-generation high-performance Digital Signal Processor (DSP), Field-Programmable Gate Array (FPGA) and system on chip (SoC) technology (DSP: 456 MHz, 32-bit. FPGA: 500,000 gate. MCU: ARM9, 300 MHz, 32-bit). Built upon a proven SDR platform with thousands of hours of operating in the field, Envoy delivers market-leading performance and future upgradability through software updates that support evolving standards and ensure sustainability. Two models are made available:
|Feature||ENVOY X1||ENVOY X2|
|Contact list entries||250||500|
|Accessory serial port||N/A||Standard|
The Envoy base station solution consists of an Envoy radio (RFU), desk console, 3020 power supply, 411 Terminated Folded Dipole broadband antenna and cables. The Envoy is the only HF base system with a purpose-built smart desktop console that provides maximum operational flexibility and full remote control capability of all HF radios on your network. Quick to setup, an Envoy base station solution provide provides a rapid link into your HF communications network.
CODAN Envoy Mobile and Base configurations
An Envoy mobile solution consists of an Envoy radio (RFU), handset (and cradle), speaker, vehicle installation hardware kit and cables. The antenna options for a mobile solution are the 3040 Automatic Tuning Whip or the 9300 Automatic Tuning Whip Antenna. The space saving design allows for the handset and radio to be mounted separately with a quick and easy install setup. Other features in short:
