I am successfully using it with FT8. Using a raspberry pi and wsjt-x. I made PTT with a USB to serial adapter and made a circuit for the RTS signal. Had a little problem because there was some sort of ground leak and the bitx40 ?stayed keyed after the push to talk released but I worked around it and if you use the proper audio interface kit that has a ground isolator you shouldn't have a problem. It's my best use of my bitx so far. I would like to add agc next. It needs it.?
