But... if all you want to monitor is Santa Barbara County, then you're probably good to go with what you have for now. The fire department(s) will likely remain conventional analog high band VHF, the sheriff's department will likely use a trunked UHF Phase II system, that I bet will be encrypted (so you won't be able to monitor it anyway). But... if you want to monitor general county government services like Parks, Roads etc. it looks like they will be Phase II conventional 800, so then you would need to upgrade. And, it will probably be three and a half years before this is fully implemented.
