Real subscriber radios? You mean like Maryland State agencies and various Maryland counties?
I'm certain most if not all of the radios on Maryland FiRST are Motorola (APX?)
St. Mary's County is a Harris system (and radios as far as I know) but Maryland State Police on that system are likely Motorola.
Carroll County is Motorola and probably Motorola radios.
Same for Prince George's county
In Maryland, to my knowledge, all other P25 systems are Phase 1.
Worcester is Phase 2 (system in testing with only 2 channels and 2 Sites at the moment). Harris XG15p, XG25p, XG75pe, XL200p, XG25p, XG75p, XG100p, P7200 and Motorola APX6000 and APX6500 Phase 2 Subscribers. Phase 1 limited operation with Harris P5100 and P7100 subscribers

Currently Central Site (Newark) and Nassawango (between Snow Hill and Wicomico line on MD.12) are online. The remainder are waiting on fiber and microwave work to be completed. Mystic Site (West Ocean City) is pending tower construction. All sites except for Mystic should come online over the next 45 days.Spent a little time in Snow Hill on Thursday... low power testing? I assume that's one of the two initial testing sites. Curious - where is the other one?

There isn't a lot of coordination / assignment. Motorola places all systems on the same WACN for some reason. They are the only vendor that does this. Harris, Tait, Airbus, etc all use a calculator to select the WACN either based on FCC call sign or a system name. From there the SYSID is the next lower level and outside of Motorola is generally customer assigned. Harris also refers to the SYSID as the "Region". In the Harris world each region can have its own geo-diverse high availability network switching centers (cores). In the system being discussed here, Worcester County and Ocean City will each share the same WACN but be two different regions (different SYSID).Ok - thanks.... This is slightly off-topic but it sounds like you might know... how are SYSIDs and other things like RFSS/site values coordinated/assigned? I've just always wondered....

The RFSS and Site ID requires no coordination as it only needs to be unique within the region / sysid.
