Tech Staff Meeting Notes November 3, 2006

Current Top Priorities are:Station Maintenance, and ET Stations. (Also wish to get INV populated.)

There are four levels of priority.
<, tr>
PrioritiesWish to try to get these done (or make progress on) before the next meeting (yeah right)
Second TierFit this in too if an opportunity arises. May be good to do instead of priorities but check with Mitch. Likely to be a priority in a previous and/or subsequent month
As Time PermitsFit these in when you can but not instead of first or second priorities
OtherStuff we hope to get to and don't want to forget about

This task list as of September 12, 2006. Note that everyone is still needed to work on essentially all tasks. There is however, a single person who is primarily responsible for each one. Mitch of course, is ultimately responsible for everything. Mitch is going to update this shortly.

Greg's todo list is incorporated into these notes.


Lenox Agreement. Jim noticed the 12 year agreement for the LNXT node is about to expire. Mitch will renew.

BB network upgrade.
Done. RP's, next friday, 4pm, nuff said?

James will coordinate with Bill or Chris when he will be going to the field and needs assistance. Notes from James:

Firstly, the radio tests in and around Tiptonville are complete. We'll likely do a relay shot from RLAP to New Markham, and then bring both sites back to the highschool in Tiptonville. We have permission from the school to use their 50' tower on-site. We'll need a second shot from our site at the Corrections Complex (NWCC) to the highschool. For this, we'll need either a roof or building mount antenna at at least 30' height. The MIS building itself (where out stuff is) can give us almost twenty feet. We'll need to buy high-gain antennas and mounting hardware, and some _serious_ lightning protection.

The second set of radio tests will be at Steele, Missouri, hopefully on 10/20. I visited this last Friday and spoke again with superintendent Mitchell Fisher. WREG has a short mast on one side of the administration building of the Steele schools for their weather station. I'm going to email our contact there to see if we can mount our antenna on that mast. The building's mechanical room has roof access and plenty of space for our radio equipment enclosure. Bob seems to be waiting for the results of this test before he buys radios and antennas.

We've not been able to secure permission to get back inside the terminal building at RLAP. To winterize the station, we need to replace the five aircells with another solar panel, battery, and a charger that will take two panels. Sure, we could trench AC power out to the station, but that would be wasted effort if we _do_ get permission to move back inside. Meanwhile, having the charger, battery, and panel hardware on-hand would be nice for one or both of our new sites around Tiptonville. Mitch and I are in agreement that we can't keep sponging off the seismic networks. We'll have to buy our own stuff.


The map shows stations with yellow triangles being new ones.
SMNC may be getting interference and the gain channel is showing up on the vertical (but doesn't look right). Turns out its interference with a nearby digital transmitter. Need to switch frequencies.
SMNC4done (see note above)
BHT8move (eventually)
ETT has some breaks in the coax. Should probably replace entire length.
Flat gap, Van hill, and GMG are on deck. Prep week of 10/23 and Chris and Greg will meet John the week of 10/30.
This was postponed to the week of November 13 and Bill will go with Chris instead of Greg. Chris got an insurance letter, need to make copies and put them in the vehicles.
TZTN needs a gate and have episensors swapped. The one there now belongs to SLU. Sensor has been swapped, John will ship the the replaced one back to SLU.
GFM has a cable problem.

Bill is getting familiarized with these so he can take them over.
John upgraded gps firmware at 2 of 3 gps. Mitch doesn't recall which ones. John says Knoxville and 2 in charleston still need upgraded. This is the list from before:
SWET-3H52, ADSC-5657, and CSTN-5637 need to have the leap second corrected. SHTN-5648 and TRSC-5662 might also but need a site visit to verify.
MSS power cycle at ADSC didn't work. John will need to visit.
CVTN and ASAR optical isolation. Need to upgrade to year 3 hardware. Hardware ready. James brought back some nice pictures from CVTN to help figure out how to do it (e.g. the conduit is way too small).
These stations are currently incommunicado:
Jim reports that frequently its just gcf2ew that needs restarted. Mitch thought he fixed this but apparently will need to revisit.
Jim provided the following regarding MVKY: Bob sent me and email recently indicating that he was planning on visiting MVKY soon. He had also had contact with Jonathan McIntyre with the Kentucky Geologocal Survey (at U of K) about being a local contact/help with this site. Since MVKY is closer to other stations that he Bob maintains he has sort of taken it under his wing.

Routine Maintenance.

Unscheduled Maintenance
These stations have lots of glitches on them (mitch took them out of the sta/lta trigger subnets),

Second Tier Priorities

NCCU Done.

Steiner Brain Dump Seminar Greg is ready. Mitch will acquire a voice recorder and Voice-to-text software. Then we'll take digital photos of anything significant on the white board. Combined, with Greg's drawings, documentation, etc, this should make a nice searchable document. Some still want to video but Mitch questions the cost/benefit.

FDL. Mitch needs to talk with Horton about what to do about FDL laptops. Bill is in charge of everything in the fdl. He'll be developing SOP's to keep track of who has what where.

3904 Power Need to draft an updated wiring diagram of 3904. Need to update the diagrams on the circuit panels. Greg put up signs on the panels with a call down list.
Greg will put an SOP for dummies on the transfer switch.

As Time Permits

Mitch needs to write an ew module to monitor the environmental channels newly installed at the nodes. Done. Its a shell script that runs twice a day. Computes several minute averages. Emails when there's a problem. Its in /gaia/home/mwithers/Projects/ENVMonitoring. The ew modules are complete and under testing on lnxtworm and mainworm. Greg and Al added the env channels to mudworm so testing will begin there shortly (much shorter trip to force a test alarm condition).

Generators Old generator needs an exhaust pipe.

Inventory Jim has all the broadband sensors defined and is working on additional equipment (e.g. isis) and the connections. Mitch will install Bill's account in mysql and inv so he can start building stations.


Ten pc's are acquired and Steve will order 5 more. All node pc's will be replaced in the coming year. We'll upgrade to ew v7.1 at the same time. This means we'll be using scnl instead of just scn. Steve, Al, and Mitch are working on the details (headaches) of that.

Many of the air cells in storage are ancient and bad. Bill will go through them and dispose of the old. Greg has method for safe and legal disposal. Done.

I-40 Bridge.
Greg will arrange and supervise regrading of HDBT. Digitizers and sensor are on order for HDBT/borehole upgrade. Greg and Steve will work out details and design. Should probably use 5GHz aironets to avoid conflicts with aztn access point and should probably use 2port and 4port terminal servers instead of a single 8 port since the surface and borehole DAS's are at physically different places. Also need to have a fence installed (after any pad, gravel or whatever is installed). Cost is $1100 installed (must be real silver).

Steve is getting a port number to establish rt continuous.

MPHB. Withers needs to determine current orientation so we can pull it and orient correctly. Helicorders look strange. Need to verify the data.

VBMS. ASL crew will install sensor, das, and vsat in November.

Leap Second. SHTN is the only one left to be fixed, all others have been verified and/or fixed. Mitch will modify the affected data.
