I have the DR-2X operational with AllstarLink in the FM mode using an external SCOM 7330 controller (internal controller essentially disabled) and the RIM-SCOM 7330 on a RPi. If you want to bridge between AllstarLink and the digital then I recommend joining dvswitch.groups.io who are addressing digital to analog bridging. Having said that, I don’t know how it would interface with the Yaesu which uses an external analog controller, but I’d ask the dvswitch group if someone has identified a configuration using a bridge with the Yaesu before giving up on the idea.
Thanks,
Bob
