Hi John,
I'm at exactly this same point with my PiDV on a new Raspberry pi 3B+ install.
PiDV works with ttl to usb adaptor in wibdows and passed AMBEtest3.py fine.

Tried the "sudo usermod -G dialout opendv with no success. I still get the following errors when trying to run ambeserver@ttyS0
pi@DV3000SVR:~/ambeserver-install $ sudo systemctl status ambeserver@...

seems to be some sort of GPIO Permission denied error.

Driving me a bit crazy trying to figure this out. Any help is appreciated.
