I have a Raspberry pi node configured ASL to DMR Bridge. I do not have any radio on this node 505501. The node is stand alone, used to connect to other remote base nodes to our DMR Local TG 315136. As such, I am not clear on the best practice for the node parameters. For example, should the rxchannel = SimpleUSB/usb_505501 be commented out. As if so, what other recommended parameters should be made.
