Tech Staff Meeting Notes February 24, 2015
The top priority is always repair of down stations.
NM problem stations
ET problem stations
Duty Table updated June 2014
The fish fry will be sometime near the end of the semester (last day of classes is Wed April 29 followed by a week of final exams). Mitch will get it scheduled. Jim suggested we could use it as an opportunity to congratulate Josephine on her retirement this summer.
The new seisnet grant is in place. Mitch sent the new account number to Jim and Steve.
Gary will meet the landowner at X203 on Friday 2/22 at 10:30 am. John will meet him there and they will decommission the station. It will be redeployed at the proposed new site for GFM. At that point it will become X204.
Breaking News Update on previous note about prolonged overcast causing station outages. CCAR, WHAR, and WLAR now have AC backup to the solar. HHAR and LCAR had upgrades to add additional solar. FCAR is supposed to get a portable building near the Firing Range that will have AC. We can run AC from there when its available. LNXT and PWLA also had solar expansions.
Breaking News Update on previous note about rtpm on hector being slow. The plan is to convert one of the rhydra machines to Ubuntu and run rtpm on it. James got the new software from Reftek but hit a speed bump with the Ubuntu install. Its should be ready soon (we'll need to switch the rtp2rtpd currently on achilles to send to the new machine instead of hector).
RTPD on starworm failed. That's twice. Need to keep an eye on this.
freewave serial reset installed at 9 of 11 broadbands.
We have not had a significant event so pulled the data from here: /gaia/smeagol/dat2/Working/NM/201502/20150224_050505_MAN
SJBM - dropping out
FPST- dropping out-spikes
SFTN - see image
CVTN - see image The noise at CVTN is due to newly installed monstrous condensor units for the HVAC
All stations were serviced. See service summary.
Three ISIS3 upgrades remain: TWAR, ARPT, and the PLAR replacement.
James has an initial mockup of a Win7 node machine with NIDAQ and adsend. Need to make sure it has all the other necessary tools and burn it in. Will try it first on mudworm then convert the BRBC machine when its pulled so that the High Peak node is Win7. Steve is going to put a second disk in it with XP so that there's a plan B if Win7 doesn't work.
All parts in house. Will be completed when we get a break from the February Freeze.
LNXT: ABB fades on some mornings, most likely due to atmospheric inversions. Jim noticed the side band at KLUV is at 60db instead of 80db. Or perhaps there's an issue at PWPT.
The waveserver as occasional periods with gaps most likely due to missed messages. Steve will investigate.
AZTN/HDBR: Shahram submitted a proposal to TDOT to replace all the sensors with Episensors (including new cabinets, etc). We asked USGS to provide new radios so we can have a continuous buffer of all channels at AZTN. We'll then allow access to NSMP so they can extract event data.
Need to review and update the power systems in 218.
CCNC is not going through fgtn and instead repeats through ASTN. The 950MHz shot would work so it could be converted to digital.
We're still repeating CPRT through GTTN. The plan was to put a cell modem at CPRT but John found a potential internet host in the local Library.
A work order is in to upgrade the Athens DSL. Currently we're a 1.5Mbps download and about 350kbps upstream. The upgrade will increase to 3Mbps and 1.1Mbps.
Don't have any recent events large enough to carry the network so we used this teleseism for station outages (won't catch bad sm channels). /gaia/smeagol/dat2/Working/ET/201502/20150222_142800_MAN
BCRT- both short period and SM
CCRT.EHE and HN? see image for EHE
We seem to have excessive RT147 problems. Need to follow up with ASL. The FDL committeee agreed to obsolesce the K2's. Jim took possession and had them removed from inventory in about 500 milliseconds.
GFM needs to be moved to a more quiet and accessible site. Possible target for digital upgrade.
Internet, accessibility, and high noise inducing RF requires we move the
MGNC central receive. John presented several possibilities and investigated
both the PSN digitizer and the Menlo Park system. We determined that eventually
we'll need to convert all nodes to the Menlo Park system so that we can obsolesce
XP. But for now, we need to reconfigure North Carolina as in
Decommission RBNC DONE
Upgrade WSNC to broadband or S-13/Reftek and cell modem. On Deck.
Rotate CCNC to repeat through fgtn and add to MTTN node. Done.
Establish new node at High Peak.
Transmit MGNC to High Peak.
Repeat TRYN through MGNC.
Transmit GFM to High Peak.
Transmit TVNC to High Peak.
Transmit SMNC to High Peak.
Node hardware at BRBC is pulled. Waiting on Morgantown cable provider to finish building upgrades. The attennas were still on the old tower the last time John was there; they're likely having delays from the nasty winter weather.
ASTN and PMTN would benefit from reconfiguring the basalts there to record continuous buffer in addition to the 100 sps rt data transfer. Done.
PMTN needs a fence?
Jim provided a spreadsheet detailing the antenna upgrades and ethernet isolation progress at each station. Presumably Green mean done and yellow means still needs work.
CJTR is still offline. Waiting for contractors to complete work at the site.
See comments in the News and Highlights section on power upgrades.
The committee provided the completed report that was discussed at the February faculty meeting. Chuck would like to see a well equipped, well orgranized and well used FDL. All that takes is time and money of which we have neither. Outside of JerMing's class and Steve Horton's portables, the equipment isn't used much.
