Just grabbed and plotted 8 hours of data from today to start looking at things. Got data from stations 2,3,4,9,10,12,13. (Only a partial file from 12, since it apparently was restarted in the middle of the day.)
In general, everything looked okay (see below). I looked at the variables: spd, dir, w, tc.5m (should be changed to .3m), T, RH.2m, Spd, Dir.10m. The only issue was that birds definitely interfere with the Gill at stations 10 & 13 – perhaps at 2 as well. I entered the boom directions for the csats, but not the gills, so I see the Gill at s4 different (but close to correct with respect to north) from the others by about 180 deg, which is expected.
I also note that the vertical velocities are quite small and don't vary, indicating both that the set-up crew did a great job of leveling the towers and that a turbine wake is not visible (expected since the winds were generally from the wrong direction).
HOWEVER, the Gill at s12 is bad. When I rserial to it, I get binary gibberish. I have now checked (using minicom) that this isn't a baud rate issue. I've also verified that "tp4" shows the same settings (120ohm termination, normal slew) as for s13, which is working. I conclude that this is not a problem with DSM settings, but a cabling issue or something in the Gill itself.
