SLPD was never on SLATER, it's always been on MOSWIN. I looked at the database and the dispatch and main car to car talk groups are still listed as DE or De, so no good on those. Looks like a bunch of ops talk groups were recently added, which can't be broadcasted on broadcastify so I am betting they don't really care since the general public can't listen in on the app, which was a lot of the reason for encryption on SLC's side anyway.
Most of the newly highlighted talkgroups are the same as before, just different names or descriptions, the talkgroup numbers themselves existed already.
What was in the clear before is still in the clear today and what was encrypted is still encrypted.
Nothing much was really added when I compared the old with the new. I had a couple TGs entered in as unknown that now have a name so I guess those could be considered new for those that scan only from the RR database and don't search out unknown or unlisted or new talkgroups.
I do wonder where the new names or descriptions came from and if they are accurate as many of the renamed talkgroups have been around for ages (think analog smartnet days) and seemed to carry the traffic their old names implied.
