Hi David:
If you don't already know about it, may I refer you to a scanner's enthusiasts website at
www.radioreference.com where there is a wealth of information on hobby scanning. You will probably find the Florida state forum to be most helpful in your quest, but you may find that a lot of the modern LE comms systems have switched over to digital operation with full encryption.
When I was in Wyoming back in the day, I contributed a fair amount about the new WyoLink statewide system, so much so that I was "honored" with being a sticky, under my W7LES callsign, you're welcome to check that out including a posting that explains about encryption & a little about my contribution in helping the stakeholders eschew fulltime encryption for the most part.
Regards,
