There is some DMR activity in the area, including Local Businesses and Schools/Universities. Most are encrypted, but some are still in the clear.
There is also the Florida FleetTalk NXDN system, which has clear activity on the Daytona Beach site. Local businesses operate on that system, too.
Finally, There is some ProVoice Active on the County EDACS system daily. Unfortunately, it is all encrypted, so I'd say that is a moot point.
