Re: uBitx on JS8Call / FT8

​​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 µBITX can be CAT controlled as a FT-817 skipping the need for the PTT with the JT modes.
