<-- Just an update folks; I've been experimenting with the auto-patch
stuff on my own system (node 2182), which is connected to a repeater -
but since I use an external controller, my node is also running as a
half-duplex node (duplex=0).
So with duplex=0, the patch does not work, there is no PTT activity on
the local transmitter - yet remote transmitters (i.e., nodes that are
connected to me) do have their TX keyed (regardless of whether they are
half-duplex or full-duplex).
I changed duplex=1; no difference.
Changing duplex=2, did the trick - there was PTT activity on the local
transmitter and my own audio was also going out over the local
transmitter (plus remotes as well) - no problem there. I need to
experiment a bit further to see whether I can sustain the duplex=2
setting with an external repeater controller, or whether I have to say
b'bye to the controller and connect the app_rpt box directly to the
This also leads me to believe that a simplex node (duplex=0) will not
work with an auto-patch. Can someone confirm this?
Also, is anyone using duplex=2 with an external repeater controller?
