??Yes -- i've done the FT-817 bit for frequency control but always just did the signalink-type PTT.? ?I have not yet done any of the KD8CEC firmware.? ??
the easy digi should work FINE -- but it lacks the volume controls and I prefer a relay to the transistor for PTT.? ?My preferences, maybe not yours.? ?I bought one early on, but didn't think it would serve the needs of our group as well.? ?
PUT A CAPACIToR BETWEEN THE UBITX PTT LINE AND GrOuND -- like 0.01 uf.??
There are LOTS of ways to do digital, nothing says that my way is any better than others -- it is just what we've done for a few dozen systems locally.? ??
I havve been using the $4.75 Adafruit 1475 --- but there are probably much better choices out there for sound card...I just haven't studied it.? ? For the raspberry pi's that we have used these on, they need a "classless" sound dongle.
More power to you!

I look forward to digging into your manual and circuit.? I've been using an easy digi board.? If you use KD8CEC's firmware the ?BITX can be CAT controlled as a FT-817 skipping the need for the PTT with the JT modes.
