Visited Lettau on 2/2/2009 at 5 pm. Approximate ground time was 45 minutes.

Team: Shelley, Melissa, Kevin Emery (FSTP)
Pilots: Lexi and Rory

Upon arrival all sensors were above the surface, including the delta T (although barely). Site was off air so we rebooted the electronics box, and it came back online right away. We checked the antenna and antenna cable and everything appeared fine. We moved the electronics box and delta T further up the tower to avoid being buried. We also replaced a battery at the site, although the 2 batteries on site appeared ok (we replaced the battery registering the smallest voltage). We cut off the plug from the battery that was left there. After moving the instruments up the tower we plugged everything back in and got a transmission immediately. Verified with three transmissions.

Heights to surface upon arrival:

Delta T: 22 cm
Electronics box: 55 cm
Junction box: 94 cm
Solar panel: 198 cm
Boom: 258 cm

Heights after raising instruments:
Delta T: 57 cm
Electronics box: 137 cm

Voltages of batteries on site: 13.08 and 12.79
Voltage of power cable coming out of junction box: 13.23
