Now Jerry, how'd you know I was going to come over here and read this thread about CW?
For my digital upgrade I will be using serial PTT rig control in Fldigi. A year ago I made the CW keying circuit found in the Fldigi Manual and added a relay module for solid sounding keying of the radio. And I hope this new control scheme work equally as well. Check out this link for the VOX style CW keying circuit. It does require a particular balance of combined volume controls (side tone on radio out, received signal, output tone on right....).

If all I wanted was a simple way to drive the Bitx40 for CW, I'd add an extra 10k resistor and skip all the FLdigi stuff.
If you already have the FLdigi stuff somehow dealing with this PTT thing, that's great.
