Tech Staff Meeting Notes March 1, 2019

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

Duty Table updated October 2017

Priorities

• Station repair
• GPS 2018 DM upgrades
• Install Cambrium radios at RCGA
• Lenox: Reinstall reconfigured Atom
• After Lenox Atom proves stable
  • Marked Tree: Install iBoot and reconfigure to have Atom replace NetGear Dual WAN router
  • New Madrid: Install Atom and remove NetGear

News & Highlights

The Nth Annual Fish Fry will be Friday May 3, 2019.

We will retire cell phone 5152 and use employee cell phone allowances instead.

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.

USGS may provide 2019 DM funds that would essentially replace all remaining older digital hardware.

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.

SIS

SIS areas of responsibility

• NM shortperiod: Dave Steiner
• NM broadband: Dave Steiner
• ET: John Parker
• strongmotion west: Dave Steiner
• strongmotion east: John Parker
• AG network: Chris McGoldrick

XP retirement. ET will be entirely digital by summer 2019 if all goes as planned. We 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.

The four wheeler is now in ET--a new one for NM is in house.

NMSZ

NMDown

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

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.

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

2018 DM GFE is in house and Centaur tests are going well.

Conversion to Digital

We have 4 USGS funded upgrades, and will have 9 remaining under the Choctaw project. USGS deadline is 1/31/2020 so the Choctaw upgrades are the priority

Need to determine the revised budget and acquire funding.

Geobits are working well

Still having trouble with the Cambium radios though John has a working pair. James will take another crack at it with John's configs. The GE links at RCGA and DYTN seem to be working well.

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 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

Bob has funds for a GPS station in ET. Because sky view is in short supply, we need Bob to identify a few sites. John will then scout those sites on the ground.

Eleven receivers for 2018 Deferred Maintenance arrived. Need to replace as trips allow. Funds (including travel) need to be spent by the end of May 2019.

All GPS sites need PM visit.

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

AG Network

Vilos is not in the allowed list of IP's for AR park internet access. Mitch will check with Cramer on shutting down smeagol and enabling its IP on a third NIC.

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.
