Well, EDACS has what they call 'test partition' where you can set a
channel or group of channels out of the normal rotation, then assign a
unit or group of units to that partition. But I think you can only have
the two partitions (main and test), and it's NOT meant to be left that
way long term.
You can also limit which channels can be control channels, and even
whether the CC rotates through or stays on one channel all the time
unless it alarms.
Interesting comparing systems...

Ain't that the truth! I'm trying to wrap my head around P25 trunking now.
Oh yeah, and now we gotta know things like IP, and networking!

Course, the big 6M rptr here is 240 Khz. By choice. But it's split
site-VERY split. Nearest rx to the tx is probably 7-8 mi line-of-site I
think, furthest is 70+.
