So alot of departments are buying Phase 1/Phase 2 radios.
How long does the county plan on staying phase 1 if everyone out the door is getting phase 1/2 radios?
Phase II is the state of the art. In fact, most manufacturers and vendors don't even actively market Phase I-only products anymore. Also consider that surrounding systems may become Phase II and interoperability will be important. I'd imagine that PSP/STAR-Net will probably transition to Phase-II P25 soon. Maryland's state-wide system is Phase-II. Chester will be Phase-II.
But yes, inevitably, there will be phase-II talk groups on Lancaster's P25 system. If certain agencies choose to buy all phase-II subscriber equipment out of the gate, perhaps they will load that agency's talk groups as Phase II to reduce system impact.
