• NM two 2024 DM upgrades
• ET station repair(ETDown is growing)
• Preventive Maintenance

News & Highlights

We are working with Swazoo Claybon a Liebert replacement plan. The small liebert is currently downm with high head pressure on the compressor and the big liebert only has one good compressor. We'll likely be using the open doors and fans method of cooling this summer.

The CR approved by congress last month includes funds to upgrade 7 ET stations and 6 NM stations over 24 months. Upgrades are targeted to states with states with federal Helene disaster declarations (TN, NC, SC, GA, and VA). Replacing geobits is a priority. Do not wish to do NM stations slated for closure as part of the conversion to digital. Original plan would require a March/April proposal with a July 1 start date. It is unclear if that's still true given the current state in D.C.

Painting 3904 room 212 (James Davis' previous office) is stalled. They found lead in the paint and asbestos above the ceiling. They'll be replacing the ceiling then painting. No estimate on timeline.

Need an alarm to send an sms message when X stations exceed Y latency. X and Y are to be determined but a first guess is 12 stations out for more than 15 minutes. Winston may not be the best metric, maybe the seedlink servers? Mitch had a slinktool based tool a long time ago but it was a pig so never implemented. Or mustang?

Need to schedule a Wiki demo and a SIS demo.

Need to get an ET trip scheduled. A new compact is on the way for GMG. Need to tackle those long term outages that aren't hampered by continued Helene impacts (e.g. MGNC and VHTN are inaccessible at the moment).

Need to update the task list. Cody is primary on GPS and AG.

NMSZ

GILT is down. Gill Center is closed for renovations and the station has no AC power. It's rarely used and very noisy: close it in SIS then remove the hardware as time permits.

Need to review station list to reduce reduncancy (e.g. PLAL) and the number of urban strong motion stations (e.g. GILT).

DM24 upgrades. CATM is complete. STAM has a better shot to New Madrid. ARPT will get done with Helene upgrades and we'll do LRAR instead.

Need six new Scala antennas to accommodate a wider field as we upgrade stations to digital. Need four for mkta and two for luxo. They are $1150 each. New account has the budget for it.

Luxora building still under construction. Good call moving our equipment to a temporary location. Several mkta upgrades will need to repeat through Luxora instead of a node. Do we need to turn it into a "node"?

CVTN/CVMS. A contractor, A2H, was hired to design and build the new school. They're aware we're there and are willing to work with us to restore those stations when the time comes.

Both UALR pipe vaults were full of water. Will replace them with a CERI style surface vault.

The City of Cape Girardeau sold the building housing sm station CBMO. Mitch has been unable to get in touch with the real-estate agent. Dave discovered the buyer is a philanthropist possibly converting it to a museum. He'll periodically check on it when in the area to keep track of changes and establish a new agreement when the time comes.

FVM. Mitch contacted Joe Davis ("Joe Davis" ) on Feb 10 to open discussions on a new agreement, sans electricity. Haven't heard back; may need to ping him again. Can probably get MO Seismic Safety Commission to help grease the skids if needed.

NMDown

ETSZ

MGNC is inaccessible.

LRVA is closed due to Helene damage. Need to recover the equipment and find a new site.

GMG and VHTN single-component problems are also long lived and need to be addressed. If disaster recovery and hardening funds become available they may be able to be upgraded to broadband. We only want to dig them up once.

ETDown

The Dalton link is dead and we're currently using a cell modem. It works but it would be nice to get the Dalton link working again. Jim has made multiple attempts to contact them but they don't return calls.

GPS

Lost contact with RLAP. Needs a site visit. GPS status page
