The top priority is always repair of down stations.
NM problem stations
ET problem stations
Be present in your work and pay attention to safety. Don't fall off the end of your rope.
The MKTA node was destroyed by lightning induced fire on Aug 22. The replacement plan includes three phases: 1) get the node back online with the six digital stations currently on cell modems, 2) convert the seven analog stations to digital with cannibalized geobits, 3) replace the geobits with standard Depot hardware. Working on Phase 1 first and need to find funds for Phase 2. Note, RVAR noise is probably analog so don't close it.
ET trip scheduled for week of 9/21 to include finishing MGNC DM26 upgrade and GFM service with new batteries. Brittany volunteered to help haul equipment up GFM.
DM26 for LRVA is on deck.
FPST and MFRT passed telemetry tests and are ready for DM26 upgrades. RELT repeats through MFRT. It is a good station if not in an ideal location. Consider converting it to digital as time and resources permit (e.g. close the analog epoch but keep the station open in hopes of a new digital epoch).
Eric may have several nanometrics sensors that were supposed to be used for upgrades to the SLU network. He is generating a list and we will need a site visit to fetch them. August update: the list generation is going rather slowly.
Can close: NMDM, WALK.

Old note carried forward. USGS is moving forward with their SLU adoptions. Unfortunately they haven't yet changed any stations from NM to GS. Mitch will continue pushing for this after the shutdown ends. See this map for plans and progress.
The last two sets of DM26 hardware from ASL shipped Aug 10.
Congress approved Helene Disaster relief funding in December 2024 and it included funds to upgrade/harden 13 NM and ET stations in disaster declared states (TN, NC, SC, GA, and VA). We upgraded 4 stations in 2025: ASTN, CCNC, VHTN, and WMTN2. Upgrades in 2026 so far are ETT (May), ARPT (April), CMGA (June), DSNC (Aug) and TVNC2 (Aug) leaving two ET (LRVA, MGNC) and two NM (FPST, MFRT) to complete.
The budget includes: Supplies $5600/station = $44,800, Travel $5312, and Gas $2,038.
MKTA server upgrade is complete. LNXT is next. NMAD, High Peak, and MTTN also need upgrades.
MTTN supermicro is moved from our rack to the College's racks and the rack was returned to CERI.
Jim reports Cody and Nick have 60% of NM/AG PMs, 50% of ET, and 55% (5/9) of AG complete.
NMAD node building has a leaky roof. Need to hire a contractor to make the repair, clean, and paint.
Remove abb hardware from water tower at Peckerwood Point.
CVTN/CVMS. Vaults are ready to reoccupy. Bob is installing a cell modem for CVMS so we can reinstall CVTN and piggyback. The station CVTN is still active in SIS but it has no active channels.

GMG needs a new cable for the titan.
LRVA is closed due to Helene damage. A crew was able to make it to the site and found a nearby clearing formed by the storm that could be suitable. It won't make the telemetry shot so will need to be a cell modem.

Etowah utilities is running fiber up to Starr Mt. They seemed amenable to sharing bandwidth with us if it can be made to work with our router. Could then get the camera going again. Camera is damaged and needs replaced. And we can bail on the Dalton link.
Need to complete PMs.
