Anyone know what groups deleted in June?
You posted this in the general CA forum, but I recognize you're talking about San Diego RCS. We got a big dump of confirmed Imperial County talkgroups entered which created a bunch of duplicate uses with other legacy talkgroups carried over from the old Motorola Smartzone system. It was clear that at some point when those Imperial County talkgroups were updated in the RCS they obsoleted other older talkgroups, but nobody on RR caught it at the time. For NorthCom, I believe it wiped out:
Elfin Forest Command 1
Elfin Forest Command 2
Elfin Forest Tac 1
Elfin Forest Tac 2
Elfin Forest Tac 3
Elfin Forest Tac 4
Those were analog talkgroups on the old RCS, which I believe were eventually replaced with a single digital Elfin Forest "EFF TAC" which is still in the DB on the new system.
The RCS talkgroups on the RR database are from at least three generations of system re-programming:
1. The original analog talkgroups.
2. The combination analog/digital talkgroups (there were some police departments where they had legacy analog talkgroups and then higher numbered digital talkgroups that superseded them).
3. The migration to P25 and resulting divide by 16 talkgroups.
Note that talkgroups were added and deleted between #1 and #2 as well as between #2 and #3, so without your guys help through submissions along with tips from people with actual Northcom fleetmaps, we won't catch these big changes.
