Their home system is Metro-25/MRRS only two of their talkgroups are in the clear, that is Watch Center, and State-Logistics. Rest of their talkgroups are full time encrypted.
They do have talkgroups on some county systems one for Watch Center, and one for ops. From what I've see the Ops talkgroups are encrypted.
Occasionally I'll hear chatter on their low band frequencies when they are testing the repeaters, and sometimes if they are in a convoy they'll use the NYTF-2 channel or one of the low band mobile channels. But lately they've seem to be favoring their 7/800 encrypted mobile channels.
