The Envoy™ is a next-generation digital HF transceiver built on the latest advances in radio communications and digital signal processing. It is designed for digital and analogue voice and for data transmission. Thanks to its built-in IP technology, the Envoy can be controlled regardless of the user’s location — in practice, from anywhere in the world with Internet access.
This makes remote programming, software updates and changes to the transceiver configuration and settings possible without sending engineers to the radio site or returning the radio to a service centre.
It also simplifies remote diagnosis of faults in the transceiver, power supplies and antennas.
As a result, operating costs fall significantly and staff are used more efficiently.
A user interface with Cyrillic support and a smartphone-style control panel make the transceiver quick to learn and intuitive to operate.
The transceiver has a built-in two-antenna switching system, which matters when the same radio works both in a local tactical network and on long-haul links to headquarters.
These tasks normally require two different antenna systems at the same time.
In the Envoy, the antennas are switched automatically as the radio moves from one network to another, including while scanning.
Codan Envoy™ digital transceivers provide reliable communications with excellent voice quality and data capability where no other means of communication are available.
HF communications with the Codan Envoy™ need no infrastructure: stations communicate point-to-point and point-to-multipoint without intermediate nodes.
The Envoy™ is a scalable system solution for building both local tactical and long-haul HF networks.
Digital signal processing and digital voice deliver excellent speech quality even in the noisiest conditions. A vocoder designed specifically for HF removes noise and interference on the channel, including deliberate jamming.
One of the key advantages of the transceiver is that it requires no special HF operating skills.
Codan Envoy™ transceivers include built-in IP capability for remote control without additional devices or accessories.
