To be short and clear this is from the latest How2. And Steve shot me this when I had my issues.
What I found at the heart of my issue was that I assumed many things not described would not have a value and the problem with that is,
it's dead wrong. Some things have default values loaded when nothing has been described.
Not normally a issue if we were only using allstar nodes, you would not hear or effect anything.
But the usrp-analog-mmdvm is always "ON".
So start with this + your link to link / duplex etc
but if anything crates output on the dmr side, you will not realize what is happening but disruption tx on the dmr side. You can use BM's pipeline to monitor tx's by id and duration for some added insight. Set it for the TG you are working with in your connection.
Set logs to '5' and check files for added info.
