So I think I went off on the wrong track, what I need to connect to is

DMR+ not Phoenix, sorry real new to DMR.

In the script I have to change to BM this command is implemented

/opt/Analog_Bridge/dvswitch.sh tune passw0rd@...:62031

What I am looking for is a similar command but to switch to DMR+

As always appreciate support and time and effort involved.
