On site: Golubieski, Semmer, Militzer, Maclean. Dave Gochis was
also at the tower site, installing soil sensors.
Installed splint at ding in tower upright.
Reinstalled TRH transducers in ventilation units at all levels.
Started installing Licor 7500's. At 43 meters, S/N 1167, port ttyS17.
Measured total power draw at data system, prior to and after unit 1167
was installed:

the adam:

Tried to prepare units 813 and 1163 for installation at 30 meters, but could not get them to boot and run with required length of cable. Red LED at circuit board would stay on, or blink on and off. It is supposed to go off once the unit is running. Measured 8 V at the end of 30 meter cable with unit attached. Need to reduce this loss.
Installed S/N 1163, and 1164 at 30 and 16 meters, but witout data/power cables.

DC power supply in power enclosure is rated at 3 A, which will not be large enough to drive system with 5 Licor 7500s, since each Licor needs about 0.9 A.
The beacon was running off a battery with an inverter. Connected the beacon directly to AC and added the battery to the 2 that power the data system and tower sensors. So the beacon is not a load on the DC supply anymore.
Installed CNR1 net radiometer. Data is being received. Distance from top of CNR1 boom to top of tower base plate is 22.38 meters. Chris said that per the bubble level indicator the unit is quite level.
Distance from top of CNR1 boom to top of 16 meter sonic is 6.31 meters.
So the top of this sonic boom is at 22.38-6.31 = 16.03 meters.
Moved network switch from adam to power enclosure. Dave Gochis will
probably use one of the ethernet ports for his Tsoil CR1000.
After this switch, the fiber/copper media converter would not
connect - even after several power cycles of converter and switch.
Had to power cycle the media converter in the seatainer. This
may mean that the fiber network will not always come up after
a power outage.
Untaped pressure inlet (13:33 MST).
Updated NIDAS software on adam.
Installed anti-climb cage on tower.
