Well if there is any provoice, never heard it, the JCSD , Fire, Rescue, EMS, Selma, Smithfield, County Services,, all hear analog in the clear. That has bee my experience. Overall the system performance / design is not great. I'm an Engineer (wireless RF design) and see that the other counties and VIPER in the area perform much better. Even Harnett seems to work better than this one.
I promise you, the system has pro voice. JCSO is using it on their main dispatch channel, so is Clayton and several other departments. It is in fact, hybrid pro voice and analog.
