I don't go where I can hear the system much but from brief monitoring and reading other posts it seems like it will be a statewide zone and primarily be used for RIPTA. I don't believe it is in full operation and only then will outsiders have a better idea of the plans.
Now, there are likely areas where this simulcast site will be stronger than the 4 older zones. Will a poor RSSI allow use of the 700? It is still phase 1 so not adding a huge increase in capacity.
My guess is the public safety wide area groups may be allowed on it but day to day PS operations will not
Putting RIPTA primarily on their own zone will improve capacity for the other zones but only once everything is finished
