Tech Staff Meeting Notes July 8, 2019
The top priority is always repair of down stations.
NM problem stations
ET problem stations
Duty Table updated October 2017
New hire is in process with HR
USGS RFP is out for next 5 year cycle. LDEO and SLU were not included.
Benz would like to install a posthole sensor as a test for a replacement of the NM analog stations. GLST/GLAT is a good candidate.
Brewer will submit work order to retire cell phone 5152.
USGS funding is in place for our three approved Deferred Maintenance items.
USGS may provide 2019 DM funds that would essentially replace all remaining older digital hardware.
NC is reviewing the GFM agreement. Mitch will contact Sue McBean, the park superintendent, to check on it.
The Trimble GPS pods for some Guralps will be impacted by a gps week rollover issue on July 28. Assuming 2019 DM is funded, replacement unit will not be available before then. Site visits will be required.
There was a discussion on the accuracy of station locations, particularly for older stations. A handheld garmin accurate to 4 decimals in degrees (about 10m) physically at the station is still the preferred method.
SIS areas of responsibility
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.
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.

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.

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:
IT scans flagged nori and folkworm, primarily due to apache. Turned it off on nori. Need to upgrade the Ubuntu OS but not while in production. We have four machines for the AQMS linux migration. If we used only two of these using VM for the rt and pp instances, then we'd have two machines to use to upgrade nori/folkworm. Mitch will check. We'll use a two machine config for AQMS and then use the third as development. The 4th will be used for the new nori.
The upgrade at CCRT still has loose ends.
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
Geobits are working well
DYTN and GRBT are using the new AMTS spectrum model with a single 50KHz channel. There is a power splitter on the radio at Star Mountain to connect two antennas and receive both stations, 6-c each, on the same channel. The web ui for the radios is a pig (use ssh instead) though it works well with the geobit web UI.
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.

Down
BCRT.HN* - ?
GFM- sporadic down interference
LRVA - sporadic down interference
Misc Problems
GMG.HNN
CPCT.HNN
VHTN- interfernce spikes
CPCT.HH* - sporadic interference - spikes
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
New station near Clifton, TN is nearly ready to install. All hurdles have been passed for the permit and it's awaiting signatures. Telemtry is complicated and has to repeat at a Water Tower before getting onto public internet at a local school. As soon as permit is signed, install monument and recon the rest. Bob will order a Septentrio but we can use an NetR9 in the meantime. Still awaiting final permission.
Eleven receivers for 2018 Deferred Maintenance arrived. But they consume significantly more bandwidth than the older receivers. Bob is attempting to get cheap radios that provide the bandwidth though the user interface is much less useful and will require more maintenance time. Proposals for new cooperative aggrements are due the end of August at which time more tech staff time will be needed in the GPS proposal.
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.
