3/1 might have been mine.
What I have noticed, is that if a talkgroup desciption is changed, it doesn't highlight. If a talkgroup is moved/added etc, it will show the change.
However, the two changes that I posted isn't clear.
32016 isn't an intertroop channel. Its the system wide "annocement" talkgroup for systemwide use. If the Message Center needs to send out fleetwide message (troop mobilizations, emgergenies etc) all the radios on the system will automatically revert to this talkgroup for the annocement. Its not a normal selectable talkgroup within the radio.
The 2nd one is:
20816 - This is the emergency revert talkgroup. If the emgergency button is pressed, its suppose to go to this talkgroup if not on a troop monitored channels (Disp/Car/Statewide etc). If its on some other tactical channel, it goes to this talkgroup and that message center should recieve it. At least that's how it was explained to me.
