I have been seeing a lot of activity on TGID 830 on the County System, without any voice coming over. Wondering if anybody has any information on this TG, may be an encrypted channel.
830 has been around for a long time, and yes it is fully encrypted.
Note that every encrypted talkgroup on the Morris County system ends with an E when looking at the HEX value of the talkgroup IDs. It's a clear pattern that they've been using since day one.
There are at least four secure talkgroups that are active on the system, but have not been identified, and therefore aren't in the database.
