They are mostly encrypted, especially law enforcement. Some encryption on fire units, but dispatch is clear on fire talkgroups. You will sometimes hear law enforcement in the clear, but not that often.
LCSO and LCPD are mostly encrypted. Sometimes I hear some in the clear, but not often. Lenoir City Fire, Tellico Village Fire, are both on TACN and are mostly in the clear. Loudon PD and FD are DMR but are clear. EMS, County Fire and Greenback Fire are analog UHF and clear. THP, Blount, Roane are all on TACN and mostly in the clear.
