The top priority is always repair of down stations.
NM problem stations
ET problem stations
Jim has shoulder surgery Friday and will be lifting and tower climbing with his finger for the following 4-6 weeks.
Review of travel claims is delaying reimbursements by a month or more.
The Fish Fry was cancelled.
NetOpsXI is Nov 1-3, 8-10, 15-17. More info here.
COVID-19 protocols are lifted beginning July 1:
2021 PM's are 73% complete.
Batteries at NM nodes are 5 years old and need replaced. MKTA is done.
ISIS5 upgrades are waiting on the enclosures that are currently scheduled to arrive at the beginning of September. Telemetry tests are complete; CWPT will need to move. First round of ISIS5 upgrades are:
MPHB continues to hang; it's an old serial to inernet DM24 system. The sensor hasn't been calibrated in three decades and has been in the borehole for nearly two of them. It is not being archived at IRIS and there is no metadata (Mitch has the original Guralp documentation though it is likely no longer accurate). We discussed whether to turn it off. It doesn't cost anything though isn't useful either. It is a nice borehole in a very noisy location so also not particularly useful from a monitoring perspective. It can be obsolesced as time permits.
WALK needs to move, Dave has a new site selected.
STAM needs to move. Landowner is prepping a new site for us.
CWPT needs to move. It doesn't have a digital path and suffers from access and other issues. Jim has a good prospect.

LNXT:
The money pit is thirsty again. It failed the load bank test and started shimmying at 60%. We may not need the full 100KW anymore but still need to do better than 60%. We have a quote of $3600 from Cummins to complete the work but Dave is having trouble getting Cummins to schedule it. He'll become a squeeky wheel.
NMAD:
AZTN/HDBR:
CERI:
NC is next up for digital conversions. These will all be Geobit/Trammel Links.
RCGA needs to move. John found a City Park in Chattannooga that is a former ammo dump. He's trying to get a permission to do a noise study to relocate the station into one of the bunkers. The city is willing to let us use the park internet.
John found a school near TRYN (Isothermal Community College) that may host internet for us. NC now wants a written agreement and provided a form to request a no-cost lease. The lease is approved by legal but finalizing is waiting on an engineering study for the new hardware on the tower; this is signficantly delayed by the engineer required to do the study.
GFM has a recurring power problem combined with poor cell coverage. This was repaired but weak cell signal remains. Jim has a new 4G FirstNet cell router on order.
Replacement station for GTTN and RBNC needs a new plan. A cell modem would
provide more options.

STAR Node
GRBT and DYTN are Tramell links to single radio at Star Mt. The signal fads causing outages in the morning. It ins't likely to get better. The DYTN path is long but solid. Is long and has obstacles. We can either switch DYTN to a 900M link or GRBT to a cell modem. A cell modem is preferred but Mitch would like an estimate for all stations likely to need cell modems so we can plan for the costs to the whole ET network rather than add them one at a time.
Freewave upgrades at STAR. There are about 4 or 5 links to the STAR node that use freewaves. These need to be upgraded to Xetawaves. The configs will require some TLC after the ugprade to get them tuned to the path. This is done and the Xetawaves are working well.
The PC is no longer needed at STAR except for SOH. But those weren't working when the crew was there last month for Centaur upgrades.
John will send the STAR SOH hardware to James to figure out how to send alarms.
Move PMTN due to excessive noise and vandalism. The new site, CATN, is permitted and ready to install.
HPNC Node
Convert all HPNC stations to digital using Geobits and Trammel Links.
MTTN Node Move the atom to the host's rack and remove our rack.
Bob has DM funding for new enclosures. He has travel and staff support but they need to be installed by the end of the GPS fiscal year on Feb 28, 2022.
Clifton needs the receiver replaced with a Septentrio and a new antenna (done). Need to make a recon for the telemetry, especially at the school (done). All the hardware needs to be assembled and mocked up (done). Install is scheduled for 8/18.
FCAR has a borrowed T120. It also has a telemetry upgrade to do. It is also scheduled for a Centaur upgrade and all three will be completed when the hardware arrives from Nanometrics.
WHAR can be put back on the local network.
Permanent portables are becoming a problem. Stations in place more than 18 months should be installed using permanent station procedures to assure the civil works are capable of long term stability.
