Update for summer 2021:
As many mentioned, all the fire departments (15, 46, 49, 51) on the island are running on the county TRS Fire Operations 2. BLFAS (Squad 12) is on EMS 2. BHFAS (Squad 14) and SCFAS (Squad 49) are still on Island Wide 2 (I need to confirm SCFAS, but I am fairly confident I heard them the last time I was down).
I do think it's a little odd that Station 49 and Squad 49 don't both use TRS, but again, I need to confirm this.
LBT Lifeguards are still using the FirstNet PTT which is supposed to be rebroadcasted on DMR 453.2625 TS1
.
BLFAS still uses DMR 155.35500 TS1
as an Ops channel, so I am not sure what portables they are using that do both DMR and P25 (maybe they are using 2 separate radios).
Fire Operations 2 and EMS 2 is not on Broadcastify, but they were on Broadcastify Calls. The Calls feed has since gone dark though.
