Summary: Ground turned by cows' hooves, Rebooted Trailer LRG, Solar power to permanent tower data loggers failed.

Sherman
1/28/2010

Arrive about 9:30. Cold, wet, foggy, little to no wind. Field is very wet. I barely got across in hiking boot from usual gate. Another gate in south-east corner a little less muddy but corn bales block vehicle access. Cows have been fed in the area south of the tower. The ground there has been turned by hooves. Lots of mushroom seen last time are gone along with most of the pepper weed. Still some annual grasses.

Trailer LRG locked up on restart from some system error. It rebooted on a hard reset and initially seemed okay but then started acting strange. Ring time all over the place 3 to 27usec, -1 and bad readings for concentrations. Shut it down and brought it in for check out. Hooked up our second ch4 only analyzer and changed CR1000 program. This seemed to run well.

LGR: 12:08pm, 2.592ppm, 8.68C, 142.26Torr, 14.396usec

Solar power to permanent tower data loggers failed (soil moisture was already on mains). I removed a redundant power line with an original power connector for a Li7500 and replaced it with a generic 12V line. This is connected to a power strip in the main data logger box that feeds CR10X1, AM25T, AM16/32, and CR10X2. I Left the solar panels connected to the battery.

Copied data and swapped cards.

Looked at changing the way the fast radiation data is recorded. Might be able to put everything on a single CR10X. Might be better to use a 23X.
