Tech Staff Meeting Notes December 9, 2019
The top priority is always repair of down stations.
NM problem stations
ET problem stations
Most of the meeting was focused on updating the Duty Table. Duty Table updated August 2019
Please verify lat/lon with each station visit. Four digits past the decimal are required (~10m).
UofM paid holidays are 12/24-1/1. Most people will be in town.
We learned at NetOps that other networks are light years ahead monitoring SOH.
Discussed the GFM installation and emphasized the need to mock-up hardware end-to-end and burn it in, prior to installation. This is necessary to avoid unnecessary surprises and tailgate construction. Sensor is most likely bad and vault needs better thermal insulation. Mitch will get data and request a replacement from ASL. We will also install a conduit around the sensor and fill with sand to lock into place. Accelerometer will not fit into existing vault so will be installed in the spring with a new vault. Patrick volunteered to carry the concrete.
A trillium posthole would fit nicely in the existing S-13 vertical vault at PWLA. That could render PLAL redundant.
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.
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.

TNMT - sporadic drop outs- battery?
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.

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:
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.
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.
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.
WMTN2 was upgraded and was supposed to repeat through ASTN to MTTN. But the link between ASTN and MTTN wouldn't associate using the GE spreadspectrum radios. So they were replaced with freewaves which don't have sufficient bandwidth to xmit both ASTN and WMTN2. So WMTN2 is down until John get's back to troublshoot this week (9/17/19).
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.

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
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.
