The FreeDV Waveform Installer add the FreeDV mode to FLEX-6000 Signature Series SDRs - FreeDV is a free, open source, digital voice communications system for HF amateur radio, which uses the CODEC2 low bit rate VOCODER (Voice Coder Decoder) developed by David Rowe, VK5DGR.
NOTE: This version is EXPERIMENTAL code and should be used with caution. If you experience crashes, simply uninstall it using the Waveform manager in SmartSDR.

Being "experimental" is fine; I suppose FRS does not want to commit lots of manpower now. But this code seems to be a good beta version and deserves at least some documentation. It's a really neat capability that brings even more glory to the Flex 6000 platform!
Because everything is open source, anyone could take what we've done and upgrade it to use the newer waveform in addition to the one we have or expand it and serve up multiple modes. We'd help someone with the skills and desires to do this, but we've just not had the time to do it here yet.
The BER is likely in the code we have and we've just not exposed it. I think we originally added a bar graph to the client and I'm not sure we are sending out the BER though.
This is wonderful stuff, promising lots of new modes -- PSK31, RTTY, JT65 ...? And, just personally, it's more interesting than remote Internet operation. :-)
