IHOP02: Site 5 Messages, 26 Entries..

06/24/02  15:45 - 16:00 Local

Purpose: Steve went to the west early today for the
	Final Trime Soil Measurement.

Cleaned RAD

Trime measurements
ISFF	17.3
P12	24.5

Remove SDR unit to install at station 9

06/21 12:05-14:45 Local

Purpose: Check RF/pwr, clean sensors, cut wheat, Install SDR
	Check RainGauge, soil sensors.

Site Maintenance:  Weed-Whacked the wheat to match the field
	appearance now that it's been harvested. 

Rain Gauge: Had an abandoned mouse nest.

Soil Sensors: Tightened connectors for tsoil 5, gsoil6 on profile.

Krypton: Cleaned; before ~65mV after ~170mV.
	Also verified s/n 1101 and file coefficients.

Goes:	Antenna was pointing down at an inappropriate angle. This
	may have been cause of drop-outs.  Realigned it and also
	installed a 3rd battery for the station.

SDR Test initiated: Shield On.  See entry 265 for times.

Move_metppf done.

EVE Problem:
	2 spurious reboots occurred while we were here.  They
	maay have been something to do with the SDR / cabling but
	that's definitely not certain.  The watchdog did restart
	things and then it seemed OK.  Did not swap cpu/etc.

6/20 17:30 Local

The site was being harvested at that time by 5 combines which were
circling in on the station.
These puppies were kicking up quite a bit of chaff into the air.
Darn it, the camera battery was dead so I couldn't take photos :-(

Decided not to visit the site at this time.  Harvesting should
have been completed by perhaps 0Z maybe.

Arrived 13:55
Recycled the propvane by unplugging and replugging sbus. Cured the problem
  of the apparent constant direction.
Down loaded /card
Departed 14:40

Noticed oil drilling rig set up ~3/8mile south of site.  Didn't appear to be
more of an obstruction than the nearest pump-jack (a rather open structure).
I don't recall seeing this before (and Tom doesn't remember it from his visits)

Arrive: 1649
[ongoing check of radiometers]
- radiometers cleaned at 1652, dessicant okay 
- converted CR10 to fast mode; 0,1,0,0,0 coefs; collected data to s5l.020607
  at 1654; shaded 2x 1min each
- converted CR10 back to normal mode at 1703
Depart: 1703

Arrived 9:15
Dropped mast, installed refurbished Kr in plastic box. Reinstalled head.
Rewired logger to third battery, PAM now has two batteries on the solar power.
Reconnected solar panels,
Copied card
Depart 9:40

[another log of this visit written later by Tony]

Visit to reinstall krypton boxes after all that Tony brought back to the lab
yesterday passed inspection and to hang them in plasic boxes.  This to be
done before a King Air PBL mission today over the Central legs.

- drove in (not too muddy)
- arrive ~0915
- dropped mast almost immediately
- reconnected solar panel
- reinstalled krypton head; installed plastic box and krypton electronics
- rewired CR10x power
- copied /card
- raised mast
- moved 3rd batter to rad stand
- depart 0940

Kr electronic boxes collected from central sites.
Site 5, arrived 9:10, mast dropped, Kr 1101 box and head removed, cables bagged
        solar panel disconnected, departed 9:45


Note (7/26/02) This visit on June 5.  See entry 204.  TWH

Arived 17:10

Installed Cu ground wire from Eve box to ground rod.

Reconnected Siamise ribbon cable connector; only power needed to be seated, 
Tsurf was already OK

Dumped /card

Departed 17:33

arrived 11:15 departed 11:55

GOES DCP returned to location inside door
Standard RF shielding procedure implimented

Soil multiplexer shields gathered for common ground with the cables associated 
with the multiplexer output

Data captured as s5.02.06.02 

.2 points added by SO
1. I think I forgot to connect a copper ground wire to replace the ground
strap that I removed.  We should do this before the next electrical storm.
2. I seem to recall seeing that the battery voltage was low.  This might be
a mis-seated AD0 connector on the EVEAD (they are hard to align!)  I should
have checked this as well.

We did a QUICK stop (1203-1205) at s5 and verified that I had left the GOES 
transmitter (SE110) off.  We left it off and did nothing else at this site.

Arrived at site 5 at ~ 13:30 and began a series of test on the GOES interference
At 13:50 began data capture, at 13:58:20 stopped data capture.  This to record
 the Tsfc and KH2O steps during a GOES transmission.  This file saved to 
 captures/s5.020530.
At 14:05 dropped mast and cleaned the Kr windows. 
 The signal increased (only) from 900 to 940 mV.  This  like a good
 level, but the dailyplots show bad data.  Hopefully, it is just a connector
 problem (though Gordon and Tom had looked at this before.)
At 14:15 demounted the Kr #1392 and replaced it with Kr # 1101. This Kr sensor
 had been brought into the base and had had the obvious corrosion inside the 
 electronics box removed and fresh silica gel in a cloth bag included. The 
 electronics box was also better sealed.
The signal changed Kr #1392 900mv to Kr # 1101 300 mv ( a decrease but hopefully
 a more stable sensor).
The TRH fan sounded fine, the Rad stand multiplexer sounded fine and the 
 propvane spun with no noise. The ports in the mast had already been duct taped  and so it was assumed that the Y cable had been inspected. 
The GOES tests result:
 noise even when Yagi deployed 10 m away 
 noise even with a dummy load
 reduction of noise on Tsfc from 250 counts to 15 counts when GOES transmitter 
 box outside the Eve box
As a result we rigged the cables out through a hole in the bottom of the box
 and placed the GOES box atop a battery box with a tupper ware cover.
We also captured the data from /card.

P.S. GOES data have stopped from this site.  We may have left the switch on the
transmitter off.  We'll have to run out again -- I don't think now, since it 
is late and Tony has left.  We'll plan on a run tomorrow -- they're planning on
flying this area anyway!

Gordon cleaned the windows on the kh2o sensor head and I opened the 
electronics box to clean the internal connectors on the bulkhead 
power connector.  The latter were heavily corroded.  

We returned to the base where Gordon repaired a broken internal connector
on the red (power) wire.  He sealed the box and connectors with Peel 
and Seal.

I cleaned the windows on the kh2o sensor head and opened the electronics
box to clean the internal connectors on the bulkhead power connector.
The latter were heavily corroded.  I sealed the box with Peel and Seal.

Gordon and Tom visted site 5 11:00 - 12:00 CDT, May 18.

We cleaned the kh2o head and the power connector inside the electonics 
box, reset the clock (from 2 sec fast to 1 sec slow), and downloaded 
the local data storage.

Gordon sealed the Y in the Sbus cable with splicing tape and Peel
and Seal.  He also filed the inside of the TRH boom and remounted
the TRH inside the boom.

The mast was down from 11:10 - 11:50 CDT.

May 12, about 19:15 CDT

Shot angles with KVH data scope (declination=6.0 east)
Sonic: 266.6, 267.3, 267.7

See entry #74 for times that mast was lowered.

after raising mast during site visit on May 12, checked the azimuths
with KVH data scope (declination=6.0 east)


From the sonic w and prop Spd data it appears the mast was lowered 
at about 18:10 CDT and raised at 18:45, May 12

Shot angles with KVH data scope (declination=6.0 east)
Prop boom: 177

Prop BD was 176, John set it to 177.  Here is the prop output:

  Closing communications

Arrived 17:30, CDT

Prop vane reporting constant wind direction, -99
Prop PO command reported jibberish.
TRH out.

Replaced TRH 104 with 704. 704 reported data.

Removing TRH was difficult, needs crossarm expansion fix

TRH704 is lashed under cross arm rather than inserted in end

TRH cable was dripping water.  Water in TRH connector.
Removed end cap of TRH housing, electronics were dry.
Somehow water is coming down within cable inside of
mast or is a result of condensation.  Shook water
drops from cable repeatedly, until, by end
of visit, cable was not dripping as much.

Tested #104 after blowing water out of connector.
#104 works, but left 704 in.

After these fixes, prop starting working - so it appears
the prop vane's problem was due to water in the sbus
cable.

Lowered mast to check for source of water entry, found
nothing obvious. Did not remove cable from mast. Raised mast.

From the sonic w and prop Spd data it appears the mast was lowered 
at about 18:10 CDT and raised at 18:55.

Note (7/17/02): Looks more like 1815 - 1850 CDT.  TWH

Shot angles with KVH data scope. See entries #75,76

Left site at 19:30

Compared logger coefficients at Site 5 to those listed in logbook entry 18.
Those for PYGIN and PSPIN were incorrect and were changed as follows

Sensor	Logger coefficient	Old	New
PYGIN	02 & 51			259.5	286.533
PYGOUT	04 & 53			80.257	110.254

It appears that this change was made around 1945 GMT, since the logger
data quit at that time.  SRS suspects that he forgot to restart the
logger after talking with it via the console port.

5/12/02, 3:50 pm CDT:

Steve returned to the site last night at restarted the logger.  TWH

Note (7/16/02):  Logger coefficient 04 corresponds to PSPIN and site 5
only had incoming radiometers, so the entries in the table above most
likely correspond to PYGIN (02) and PSPIN (04), as noted in the
preceding comment, rather than PYGIN and PYGOUT as listed.  TWH

Site 5 was completed today.
Sonic serial number: NUW 3
Sonic Height: 5.0 m
