Tech Staff Meeting Notes November 6, 2018

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

Duty Table updated October 2017

Priorities

• Station repair
• Annual preventive maintenance
• BCRT rebuild (Drywall John needs assistance to dig up the sensors)
• Choctaw Short Term Plan

News & Highlights

Both Chris and Dave had other obligations which prevented their attendance at this meeting. We decided they can draw straws to see who will be digging up the sensors at BCRT.

There may be funds available next year for another round of Deferred Maintenance. Conversion of the NM network to digital is the obvious choice with Ogweno's EEW map as a guide for setting priorities. What other needs are there? Mitch needs a bulleted list by the end of the month--it need not be detailed.

NetOpsX will be March 5-6 at the University of Memphis.

USGS funding is in place for our three approved Deferred Maintenance items.

• AQMS upgrade: replace obsolete AQMS systems with new redundant linux/postgresql developed at PNSN. GOAL: Linux/Postgres in production parallel to Solaris/Oracle by the end of August 2019.
• New transfer switch for NMAD and new resets for each of the NMSZ nodes
• 4 ET analog to digital conversions (6 channel) for GRBT, ETT, CCRT, and GFM. Three will stay shortperiod and add a sm. GFM will convert to broadband. Hardware will be Centaur DAS, Titan sm, and a Trillium PH for GFM. Hardware orders are in process now.

NC is reviewing the GFM agreement

There will be a GPS week rollover (max week count exceeds 1024) in April 2019. Some of our clocks may be affects. Dave Wilson at ASL is taking the lead to contact vendors for information on expected behavior.

Mitch asked Chris To delay his retirement to May, 2019 so assist with the ET conversion to digital.

SIS

SIS areas of responsibility

• NM shortperiod: Dave Steiner
• NM broadband: Dave Steiner

• strongmotion west: Dave Steiner
• strongmotion east: John Parker
• AG network: Chris McGoldrick

The Choctaw short-term plan is on schedule.

XP retirement. We are moving ahead with the Choctaw Short-term Plan. It is important stay on schedule. Phase I replaces the radios at DYTN. Phase II builds a new Raspberry Jam (RJ) prototype and upgrades TVNC2 to digital.

Metadata Update	12/3/18	12/7/18	Davis, Withers
Station Certification	12/3/18	12/7/18	Withers, Davis

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.

NMSZ

NMSZ Routing service is just over half complete.

NMDown

There are 1 of 7 ISIS3 upgrades remaining (NHAR).

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

I40 Bridge comms.
Done. All channels are available on lawworm--need a web page for the helis.

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.

NODE Tasks

DBB:

MKTA:

LNXT:

Adjust startup delay in transfer switch settings to give generator time to warm up.

NMAD:

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:
Server room power is unbalanced. Need to balance when three new AQMS machines are racked.

ETSZ

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. John and Chris will schedule a trip.

ETDown

CPRT has many gaps though the telemetry is solid. This is Phase I of the Choctaw Short-term Plan

STAR Node

BCRT took a lighting hit. Needs new sensors and electrical ground upgrade.

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

All GPS sites need PM visit.

There was a miscommunication with the Clifton site and internet access. Bob is looking at alternatives.

There was an internet "upgrade" at MACC. Need to reconfigure GPS networking configs; James may be able to do it remotely.

AG Network

Z41A has a leaky vault. It will need to be replaced with a CERI style vault.

HHAR needs a bigger solar regulator. The new one should last a year.
