The only full-time users are Sacramento County Local Government (Rangers, Public Works, Probation, etc.).
That does not include the Sheriff. However, you will hear some Sheriff, Fire, and West Sacramento Police talkgroups active on the system because someone has a radio tuned to one of the channels on the P25 side (you can see this watching Unitrunker, a full P25 radio ID joins the P25 system and talkgroup which will cause the analog side to simulcast to the P25 system).
