FreeDV

Ever tire of the whistles crackles and poor audio we take for granted with HF phone?
It doesn't have to be like this if you use freeDV, free Digital Voice. Yes, it really is free, as in beer. There are no restrictions as to what you do with the freely dowloadable code. Make it better, if you can.
Details are at https://freedv.org/ with lots of info and a downloadable manual.
It works a bit like other digital modes, in fact the freeDV website claims if you can use WSJT-X, you can do freeDV.
A soundcard or interface is used between the computer USB and the rig, just the same. The only difference is that you need another soundcard, maybe the one already in your computer's sound to join a mic and speakers to the computer.
Hook it up as they show, and enjoy, but remember the PTT is not on the rig's mic, but is now the keyboard spacebar -because you are now talking through the computer, and the computer controls the rig.
It's a lot of fun. Listen around 14.236 USB for a rasping sound digital QSO, which become clear speech with the freeDV software. (The nearby rhythmic sounds on 14.230 are most likely SSTV, rather than freeDV.)
