The New Crownsville site has structure delivered, and what appears to be a new fiber optic leg installed along Hawkins Road - perhaps they made a deal with the state to share fiber since they are co-locating the new tower alongside the existing MIEMSS / First site.

The Davidsonville site has finally got some tower construction happening:

And the Lothian site has completed erecting the tower structure, and has even mounted one RF antenna. You can see the transmission line race on the ground waiting to be installed. The shelter is in place, along with a backup genny mounted on top of the fuel tank - I don't think I've noticed that before, but it's a good idea if vibration in minimal.

Tower structure complete at Davidsonville; that leaves only the monopole at Brooklyn Park and New Crownsville yet to be completed.

Anne Arundel units have been running a disturbing number of positive PUIs this morning. Merry Christmas.

PUI responses continue to wreak havoc with transport units and hospitals today. Annapolis area is being covered by transfers; most area hospitals are on condition red and yellow; both county hospitals are on reroute:

The county has posted a sign where the Herald Harbor VFD is moving to - the site of the old Wawa on Generals Hwy at Sunrise Beach Road. New name too: Crownsville Fire Station. Completion date Fall 2024. The new Jacobsville station is nearing completion, and the relocated Woodland Beach station will be located at Rt 2 and Rt 214 in Edgewater

Truck 39 has been testing Repeat 3 on Mike in a structure somewhere in the Annapolis area this morning. They were also testing RINS 1 as a direct channel - not sure if RINS 1 always uses a repeater - I don't know why they would be using RINS in a structure if it relies on infrastructure. Perhaps testing a BDA? Just a note when you hear a tone burst in front of a transmission, it indicates that a VRS channel is being used.

RINS does not use repeaters here.

The county's RINS license WRCC324 confirms this, but also indicates a Temporary Fixed mode. Perhaps the county's MCP (or SOW if there is one) has a capability to repeat these channels? /speculation.

Hotel has been added to the working tg list. Not sure if the outage is related to being in the AECC in Glen Burnie (if they are still there.)

Seems like a console issue, however I looked at my logging software this morning, and it had dropped the AACo system at 10:59 last night. The software typically runs 24/7 for weeks at a time without failure, so I'm not sure if it was coincidental or not. Seems related, particularly since it was also logging FIRST which was not interrupted. The post at 12:52am was made after a long tone sequence announcing the problem.
