The marine radios manufacturer Codan has a new series of radios called Envoy, wich seems to be a very advanced HF transceiver. It is based on SDR technology and has 2 types of modern interfaces (one for use as a base station and a more compact one for use as mobile), it is IP capable and can be reprogrammed remotely via internet and has an internal software modem that supports high-speed data, chat and email.

 The list of specifications as well as other details about the Codan Envoy can be found on the Codan website, but here are the specs for the RF side:

Frequency range
– Transmit:    1.6 to 30 MHz
– Receive:    250 kHz to 30 MHz
Frequency Stability: ±0.5 ppm from –30°C to +60°C
Modes    Single sideband (J3E), USB, LSB, AM (H3E), CW (J2A), AFSK (J2B), F1B (FSK) (software controlled filter bandwidth)  
Output power: 125 W PEP ±1 dB (two-tone or voice), user-programmable (low / medium / high)  
Duty cycle: 100% Voice / Data with optional Fan  
RF output impedance: 50 Ω  
Filter bandwidths: 2.4 kHz standard (500 Hz, 2.7 kHz optional)
Wideband software programmable filters available on EnvoyTM X2 model  
Transmitter specifications
– Spurious and harmonic emissions: Better than 64 dB
– Intermodulation products: 33 dB below PEP
– Carrier suppression: Better than 60 dB below PEP
– Sideband suppression: 70 dB below PEP
Receiver specifications
– Sensitivity:    0.12 μV, –125 dBm for 10 dB SINAD
– Selectivity:    > 70 dB at –1 kHz and +4 kHz ref SCF USB
– Blocking:    > 95 dB at ±50 kHz
– Image rejection:    > 70 dB
– Spurious response:    > 70 dB
– Intermodulation: unwanted signal 92 dB below desired signal
– Switching speed: below 25 ms (RX:TX and TX:RX)

Unfortunately for us amateurs it doesn’t have a VFO mode, wich makes it a very high-tech useless piece of equipment.
