Tech Staff Meeting Notes February 3, 2020

The top priority is always repair of down stations.
NM problem stations
ET problem stations

Duty Table updated August 2019

Duty Table updated February 2020 to add Giddings and Ditchwitch O&M.

Priorities

• Station repair and routine maintenance
• FDL cleanup
• GFM replacement TC test and install
• New valve for propane tank on the Money Pit
• AMTS FCC applications

Please verify lat/lon with each station visit. Four digits past the decimal are required (~10m).

News & Highlights

Both SLU O&M and DM20 supplements can't begin until after the DM2019 no-cost extension ends. The planned start-date of April 15 may thus be ambitious. Mitch will speak with USGS mgmt about a June 1 start.

SLU O&M supplement will include the same eleven stations as proposed last summer in the seisnet proposal: CBMO, CGM3, FVM, MGMO, MPH, PBMO, PLAL, PVMO, SIUC, UALR, UTMT.

Need to schedule a visit for Eric Haug for discussion on assuming operations of SLU stations and Q330 data flow and maintenance.

DM2020 supplement proposal will include 10 analog-to-digital conversions in the NM network. We will request 6-c Centaurs with Titans for ten stations. Three of the components will connect directly to the existing shortperiod ISIS sensor package. The Titan is necessary to make them compliant with ANSS RSN performance standards. We'll also include several pairs of Xetawave transcievers to replace Freewaves and GE radios where possible.

GFM TC replacement shows differences with a second TC in the CERI test vault at frequencies less than 0.1 Hz. The differences are very small and only noticiable on background noise (i.e. very low signal to begin with). It likely is not a sufficient issue to prevent installation. We'll add two more TC's for a more complete huddle test.

Mitch is working on a new agreement for the Tower at New Madrid. Horizon Tower Group (HTG) has closed on the tower and the land lease is formally transferred to them. The new CERI lease with HTG is winding it's way through the University.

Mitch is also working on a renewal to the agreement with WASL for the tower at Lenox. Done.

SIS

XP retirement. ET will be entirely digital by summer 2019 if all goes as planned (hahaha). Spring 2020? Need a plan for NM.

RTCC on Ubuntu 16 is able to get /parameters but fails with /status-control on loopback and RTPD hangs. It works in Ubuntu 18 but openvpn does not. Wait for that fix then leapfrog OS to 18.

A p-plant Contractor performed a detailed review of the two lieberts in room 218. The report is under review and a PO is being issued by p-plant to complete the repairs.

NMSZ

Need to assist Pat Lane in installation of telemetry tower at new Red Cross HQ on Madison near Cleveland. Their old premises had a tower for emergency two-way comms but their new facility does not.

NMDown

Make permanent, repair receive mast for WYBT at HOPT install four 52 watt panel.

Strongmotion stations NAIT, SEAR, and NHIN are having trouble moving up the priority list. of the three, SEAR is most valuable. NHIN is probably a fuse but can wait until there is a new obisidian to replace the 5TD.

NHIN shortperiod channels are working now that the internet connection is restored. The strongmotion channels are still down. It'll be second priority when new DM2019 hardware arrives from ASL. We will also decommission the PC currently used to digitize the sp channels (Windows XP) on install a modern, low end PC to be used solely for a swarm display. It'll then be just 3-c of strongmotion (Etna2) sent directly to Memphis.

NODE Tasks

DBB:

MKTA:

LNXT: Generator propane tanks needs a valve. The tank will need to be emptied to replace it. It's currently about 40% full so we'll need to top it off after the repair. The last fillup was August 2016 and cost $1623 for 725 gallons. Jim's Generator expense summary is here.

NMAD:

DBB at NMAD loses connectivity when the node is running on battery (i.e. when the AC power is down).

AZTN/HDBR: Need to pull the 200' sensor at the weigh station. Probable water damage. There is no budget for this. Should we try to repair the sensor at MPHB and put it at HDAR2 (MPHB is over two decades old, possibly closer to three)? Should we turn off the HDAR2.*.20 channels until the sensor can be replaced?

CERI:

ETSZ

GFM needs to have sensor replaced and sand-filled conduit installed for the short-term (February). It will get a new vault in the long-term.

CPRT needs new VPN creditials to connect to new server that replaced rhydra4. Currently udp is sneaking through on the reftek rdp but need the credential to make direct connections with two-way communications.

DYTN GPS pod needs a firmware upgrade. Done.

Camera at Star Mt no longer has a supported web interface. Steve is looking into a new one as well as basic cameras for all the other nodes.

John is working on FCC applications for the Choctaw links using the 10/13 study done by L&G.

ASTN-MTTN had antenna upgrades and the GE radios were replaced with Freewaves. It remains unclear why exactly the GE radios did not work though they appear much more sensitive to degraded signal strength. This links repeats 9 channels and MTTN has a lot of RF noise so the GE radios should be less problematic on strong links with a single station. We will try Zetawave radios there.

Replacement station for GTTN and RBNC needs a new plan. A cell modem would provide more options.

Need to remove antennas, coax, and any other hardware from the tower at Greentop. Done.

ETDown

STAR Node

Needs a new camera.

BCRT had an intermittent 40Hz spike.

Move PMTN due to excessive noise and vandalism. John has a site and sent a draft MOU to Mitch. The University did not ask for changes and asked for the WMA director to sign first, its currently in Nashville for approval. A portable was installed and shows no surprises, it should a good quiet site.

HPNC Node

MTTN Node

GPS

New station near Clifton, TN was installed the first week of December, 2019. There is currently no telemetry. The plan is to telemeter to a nearby water tower, then to a local community college on public internet. James is requesting a formal station name but needs a lat/lon for it.

RLAP NetR9 is dead.

MAIR not tracking satellites.

AG Network

FDL

FDL needs better battery storage (should be on contained platform rather than the floor).

FDL cleanup continues. Rather than obsolesce the old mk2/serial fire-wire CMG6TDs, we'll put them in long term storage instead (fdl attic, mcgoldrick garage attic, or house 3 cedar closet are all good candidates).
