Tech Staff Meeting Notes August 4, 2008
Current Top Priorities are: Station maintenance
The fish fry will be on Friday August 15.
Chris and Jim Napors completed acquisition of a new vehicle for John. John will drive his old vehicle to Memphis the week of August 11, join us for the fish fry on August 15, and return to NC with his new truck. Chris will need to get it ready (e.g. decals, plates, roof rack, winch etc).
There are four levels of priority.
|Priorities||Wish to try to get these done (or make progress on) before the next meeting (yeah right)|
|Second Tier||Fit 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 Permits||Fit these in when you can but not instead of first or second priorities|
|Other||Stuff we hope to get to and don't want to forget about|
The task list updated February 6, 2008. 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.
Station Maintenance, NMSZ
Station maintenance is the top priority.
Several of the stations can get improved telemetry by transmitting directly
to the node. The original configuration changed enough so that there is
room in the band. Jim will investigate.
Holly's list of problem stations:
Isis Oxidation problem
Down or unusable
TIPT replacement. The permission with the TN Department of Corrections is complete. ETN
CCRT - Needs a rebuild after a bad lightning strike.
NC Node - Need to figure out how to fix GPS time drop-outs. Jim suggests making sure the clock is configured correctly and not alarming on inconsequential hiccups.
GFM - Fixed the bad channel but still needs some work to repair storm damage.
RBNC - Replace battery(s), and add another solar panel.
GMG - Need battery box solar reg mounting plate and need to fuse the battery.
Need to acquire and install new batteries for all the XLAK clocks.
Routine Maintenance Kudzu, battery check, etc, etc.
Second Tier Priorities
Most of the strongmotion stations can run at 100 sps without any modifications. We will install a router on the few that have problems (RDST will be the test case). We will also migrate the acquisition software from gcf2ew on anssworm to scream/scream2ew on a linux or ms server. The latter will facilitate stations maintenance without interrupting the data stream.
On the CMG5TD's, Mitch found that for GNAR and LNXT we must first set the
filing mode to filing and then set to dual. Otherwise trigger messages
show up in the logs but the waveforms are not stored. This trick did
not work at SFTN, RDST, GILT, or HDBT. Why not? Possibly firmware
Using the CMG5TD from HDAR as a test, we couldn't get it to trigger (neither message produced nor waveforms saved). Installed new firmware and it works fine. Bill will return to HDAR and upgrade all CMG5TD's sensors.
Need a new bottom air conditioner for mkta.
Need new RF preamps, radio align, etc, etc at MKTA.
PEBM and HENM sometimes have telemetry fades. Should reevaluate comms.
Need to knock down the jungle around the guy anchors at NMAD.
Need to finish the tower work at NMAD.
Need to swap out the old node computers at NHIN, and AZTN. Will XP do netbui with the bridge recorders (if so we could lose the windows 98 box at aztn)?
CJTR still needs comm and a service visit for data download, routine maintenance, yada, yada.
Lost line power at PTGV. Not sure why. Will run on battery/solar as long as we have good sun. Could just be a loose wall wart? Should we wire tie it or something? Chris will investigate.
LRVA - East/West channel has low amplitude and needs troubleshooting.
WSNC - (Winespring Bald, NC) - Have Special use permit from Forest Service. Need to determine details of exactly what goes precisely where. John will get some pics and discuss via phone with Jim and Chris.
Fort Payne - John found a good spot with decent odds of a permission at Desoto state park in Alabama. It will have to repeat through a Georgia fire tower and John is investigating the permit there.
The map shows stations with yellow triangles being new ones.
|SMNC||4||done (see note above)|
The recorder disks should be reformatted as a routine maintenance task next time access is available. The constant read/write to the fat file systems lead to fragmentation. Don't ya just love dos?
Lost contact with recorders 1, 3, and 6. Number 5 is unstable. Can reset all 7 recorders which implies the equipment enclosure at each node has power and that at least the reset radio and telemetry are working.
This is the point where we hop on the TDOT wireless network. Its also a strong motion station. When the funds come through, this will become an 18-component "station" like Mud Island. The surface station needs to move to where the boreholes will be. Chris met with AR DOT people and figured out where everything is supposed to go. TDOT will likely be ready for us in September.
Mud Island vertical array is operational. Not really, functional is a better word until we can get it online to qc/vet data.
Steve needs to speak with Dean Kemp at NWS. They are willing to let us piggyback on their cable internet (not .nws.noaa.gov).
Lenox Agreement. Jim obtained contact info for the person Mitch needs to call>
This is the FDL Policy.
Two firewire terminals need to be refurbished and sealed.
The CMG6's are ready for deployment but we need 3 firewire cables. Bill will contact ASL to see if they have a more cost effective option than the $500 ones from Guralp. Otherwise I guess we'll need to get them from Guralp.
Need to make ready for deployment all K2's.
As Time Permits
Can we route Pat's alarms into the earthworm digitizer? If they are just a flat -5/0/+5 voltage that monitors a state change, it should be easy to add them into the env_alarm channels.
CPCT - Re-work lighting and pest chaser. John has a pest chaser and will use some landscape or pool hardware for the lighting.
SWET - Need to seal the hinges on the aluminum Hoffman boxes with flashing tape to keep the water out.
3876 Power The power for the new lighting on the east side of the general parking lot to the west of CERI is coming from 3876. Chris will check it out to assess the added lightning hazard and see if anything can be done about it. Might be hard to do without the wiring diagram. Chris will make one if needed as time permits.
Chris is going to make a diagram for 3890. Good luck son.
Inventory Mitch needs to look at this and determine where we are and what needs to be done to make this operational.
Withers needs to determine current orientation for MPHB so we can pull it and orient correctly.
Pink Palace is working with Gary and Michelle on a new perc-like display area. We'll pull the receiver etc, when they start pulling out the old display (or sometime earlier if an opportunity arises).
Jim will switch the FCC licenses from Greg's name to Mitch.
