The top priority is always repair of down stations.
NM problem stations
ET problem stations
2023 DM request was awarded. It'll take a few weeks to get an account number. Funded were continued O&M of adopted SLU stations, pgrade of five NM analog stations (cascadia PH w/ Centaur), continued migration of pAQMS (funds to put secondary aqms with replication into production), upgrade remaining six antennas at NM nodes, upgrade DBB (cradlepoint system), and acquire a 1MHz-6GHz cable and antenna analyzer.
Matt Huebner from TVA will be visiting on July 20. We hope to learn about upgrades and new instrumentation in their monitoring and gain real-time feeds where appropriate.
New AG contract is in process. The old contract expired June 30.
Need to review duty table at the next staff meeting.
Storm damage was quickly repaired last month at SFTN and the MKTA node. Several mkta stations still have weak signals which may indicate damage or mal-oriented antennas as the station. Need site visits.
CVTN is down for the current after the Covington Tornado destroyed the school. James will close the current equipment epoch but keep the station open to help avoid excessive downtime for the station. Nothing can happen until construction is well underway or complete at the school.
Discussed NM digital upgrade plan What to do about stations that need major work but are to be closed as part of the plan. Need to have a prioritized list of station upgrades and target the ones near problem stations first. So that as we do the uprades, we can close those nearby that are scheduled to be closed.
2022 DM.Z41A is on deck. Need to rent a backhoe to dig the hole for the new vault. All the hardware for SFTN is in-house and ready to go. All other DM is complete.
HOPT2 needs an antenna upgrade at the node receive. So do PENM and PGVM. Eventually all node 900MHz antennas need an upgrade to allow sharing digital bandwidth. Have the antennas and need to install.
We operate 18 cell routers and there are seven remaining upgrades to FirstNet. Only GFM remains. Have the router. Dave and Pat will plan a trip to install along with the work at fgtn.
WYBT and CWPT (replaced by CWPT2) are now closed.
Note, there is still one ISIS2 station: TMAR.
Replacement batteries are in house for DBB nodes at Wilder, MKTA roof.
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.
HOVM has telemetry interference at the Luxora repeater. No good workaround. Convert it to digital. Done, got Centaur, I5/titan upgrade Oct 2022.
Both UALR pipe vaults were full of water. Will replace them with a CERI style surface vault.

QUAR needs a tower.

CERI:
411 is stuck in 2-wheel. Needs repair.
MGNC needs more solar and a new antenna. Done, may need even more solar.
Need to test the internet at PARI. Done, works great.
BCRT replaced radio; now back online. Landowner dispute is troublesome and got one of our locks cut even though it was daisy chained with others. Power is now coming from a local radio station with a tower at the top of the mountain. John will put up a flood light in at the circuit box we get power to help defray the cost of the power we use (though the light will probably use more power than the station).
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. This lead is a bust, looking for a new location.
fgtn needs a solar upgrade. Built up and ready to go. Waiting on a break in the weather.
Replacement station for GTTN and RBNC needs a new plan. A cell modem would
provide more options.

WSNC - random interference bars approximately 5 minutes long
DYTN.EHN &.EHE -see image
LRVA & VHTN -intermittent dropouts at night
TVNC2 - intermittent dropouts
CVVA may need a cell modem.
STAR Node
Star Mt special use permit with USFS is expiring. Mitch sent in paperwork for the renewal. Will probably cost $147 one approved.
John is working on the special use permit renewal for CCNC.
Got a past due notice for internet at FPAL. We had an agreement for no-cost internet and never received a bill. John will look into it.
DYTN owners are allowing us to stay. They asked for a load of gravel for the access driveway.
The Dalton link is dead and we're currently using a cell modem. The cell modem is doing a very good job but we still would prefer to use it as a backup not primary. Long story short, Dalton thinks their stuff is working and correct but we still can't connect. Discussed options but the Dalton link is still the best option so need to figure it out and make sure what they have configured is the same as what we think they have configured. John reports, "Mr. Watts is going to let me know the next time he is heading up to Starr Mountain so I can meet him there to figure out what is going on with our connection to their network."
John will send the STAR SOH hardware to James to figure out how to send alarms. If this isn't in production soon, we're going to bail and get something off the shelf. The GX620's need to be retired. What is the status of this? It's almost there.
Move PMTN due to excessive noise and vandalism. The new site, CATN, is permitted and ready to install.
HPNC Node
WSCN noise appears to be a local source not telemetry; appears to be a pump-like source. We would like to identify the noise but it is a heavily used repeater site for multiple parties. There may be nothing that can be done. It's a good enough station that we may need to just tolerate it if a source can't be identified and mitigated. If it is a pump could we offer to pay to base isolate it?
MTTN Node
Move the atom to the host's rack and remove our rack.
VHTN seems to eat sensors. There isn't a pattern in needed repairs.
PIGT is down. Can get to the web page but it's not populating due to no data from the receiver. Have a cable analyzer to help troubleshoot.
SCCS needs a signal booster.
NWCC needs a new buried hardline.
PIGT has a cut hardline.
FCAR has it's repaired original sensor back and shiny new cables, radios, etc. This is fixed the nightly outages and the long-period noise.
Have a spot to try for a new station near Batesville.
