I have picked up a Trunking Control that I think is part of the FL SLERS. It is not listed in the database, becuase I can not confirm it's from the SLERS. See what you can hear, 851.9375 and SID 39
The licensing vs. actual transmitter installation for SLERS is not perfect. It seems like they work from a pool of Statewide frequencies. Sometimes actual transmitters are licensed, sometimes the licenses don't have transmitters, sometimes everything is licensed and on-air. TT
