[Allstar Digital] MMDVM analog

OK I was reading this guys webpage about a setting called muti-mode that
MMDVM will switch automatically to the mode it receives.
http://ve1cra.net/main/dmr.html So that's why I ask the question. I don't
know much about the MMDVM and how it would work with ASL..

Thanks, David
