I'm attempting something similar to what you did and have a question or two.
1. When connected through echolink for instance, will the transmission be received on all the ASL nodes and broadcast to the various digital modes?
2. Is each instance of mmdvm_Bridge Analog_Bridge and DVswitch running on the same machine?
3. What is the process used to connect to the system with DVSM?
4. Do you have setup details that you can share?
