None of the TGs are strapped. Consoles have the choice of turning on or off ENC on the fly for Interop purposes. DNREC as well as other LE fleet maps have the fire and EMS TGs in them. Responses in the water where Fireboats are responding have an automatic DNREC notification. DNREC can switch to and operate on the Fire tac channel and communicate directly with Fireboat units.
Lets not forget that county or state owned radios have the keys while the independently owned FD units do not. There is numerous times where County medics inadvertently switch on Enc or DSP turns off. Its a small switch, it can get flipped easily and accidently.
DNREC falls under DSP and is dispatched out of the Kent Center. They are overworked there enough already. Regardless of if they have ENC on or off, the console will hear it.
They also have temps in the summertime that look young enough to be in college still... I'm sure they don't know the difference between ENC on or off.
