Montgomery & Prince George's Cells are now showing up as peers to Anne Arundel on Unitrunker.
I just drove from Gaithersburg to Annapolis around 10PM and did not see the sites actually on the air - I check my programming to see if they were enabled.

Better coverage along I-495 in the White Oak area from the Montgomery simulcast site - not sure if this issue was addressed earlier. PG simulcast is good until the Annapolis Waterworks along 450. The only channel grants that I saw were on the PG simulcast from FIRST techs - enc of course. The Area 8 -> Area 7 patch is seen on both Montgomery and PG sites. So far it seems that Charles, Montgomery and PG sites are spitting out RF. The last schedule had Zone 5 going live (with operational traffic) in April, so I expect some more GOS testing on the network side; RF coverage testing was completed earlier in the deployment process.

According to Budget testimony....

-The last of five geographical implementation phases, which includes Montgomery, Prince George’s, Calvert, Charles and St Mary’s Counties, is scheduled to go-live for operational users in April of this year, completing the scope of the original MD FiRST project.

-In 2022, new sites were added at Taylorsville and Sykesville in Carroll County, as well as at the Maryland State Police Barracks in LaVale (Allegany County).

-New sites in Davidsonville (Anne Arundel County), Greenbrier State Park (Washington County) and Swallow Falls (Garrett County) are in progress and scheduled to go live in 2023.

-Our fiscal year 2024 capital budget request is for $18,440,000. This funding will support four major efforts: new radio sites, fiber, geographically diverse control sites, and in-building amplifiers.

-The new sites are planned for the following locations: - Cumberland (Allegany County) - Patapsco State Park (Howard County) - Queenstown (Queen Anne’s County) - Elmer School Road (Montgomery County) The Patapsco and Queenstown sites are being built in partnership with the local county jurisdictions.

-Also introduced in fiscal year 2024, is funding to support the addition of Geographically Diverse Control Sites to the network. The MD FiRST system is comprised of 22 cells, each with a single primary site that is responsible for controlling and managing information for that specific cell, while also connecting that cell to the rest of the network. Adding a second and geographically located prime/control site within each cell provides redundancy in the event the primary controlling site is disabled due to planned or unplanned events including power and backhaul outages, reducing the risk of a large-scale radio coverage outage directly impacting operational users. The budget request supports funding one geographically diverse control site to be added each year.
