Is Grimes, Brazos and Washington County Phase 2 or 1 or both.
I'm not in that area, but so far, the database indicates that all three are still Phase I. The system itself is capable of Phase 2, but still has a number of Phase 1 talkgroups in use.
I do remember seeing comments before, that in the not too distant future, users in the Houston metro area will be required to upgrade to Phase 2. No idea if that requirement will also apply to the other areas on the system.
