Robert, fldigi on linux does CW and in my tests received as well as cwget. It allows for AFSK and hardline keying via the key input on your radio. There was a bug with hardline keying in the older alpha versions so it is best to run the latest code from w1hkj.com. Of course, full source code is available, and there is an active user and support base.
It seems to receive best with machine generated code at > 10wpm. Like most programs it seems to lose sync with slower or farnsworth code - I think it would be a lot of fun with digital ops at each end at 20 wpm or so running QRO hardline keying. 73 de Brett VK2TMG
