The other factor is P25 Phase II. While that's not currently needed for the OP's location, it may be needed for areas that are traveled to or through, whether for business, pleasure, or visiting relatives. Here in the DFW area,we currently have two Phase II systems (actual Phase II, not one
capable of Phase II, but currently using Phase I, like Plano's
PAWM). Those are the Irving layer on
FWWRS and
Forney. But, by this summer, Carrollton wil move to Phase II. In the next 12 to 18 months, maybe sooner, Grand Prairie will switch to Phase II (as a layer on FWRRS), and Garland and Mesquite will combine their systems into a new Phase II one (both are analog Motorola Type 2's at the minute). There are more announced and/or in the planning stages.
