Kurt and I went to the bao site to fix the EC150.  Swapping cables, reseating the terminal block connectors, and swapping EC100 electronics boxes didn't help.  Changing from a titan to an emerald port did.  This sensor is now on port 8 (this required Kurt to change the jumper on this port).  Gordon made the config changes from Boulder.  A detail: we also added a screen to the (new) EC100 temperature inlet.

In the process of lowering and raising the mast, the mast height shifted.  We moved it back, but it now is 1-2cm higher than before.  Also, the boom angle may have changed.  I took two photos to try to document the new boom angle.  Using the previous GPS location and resolving what the photos see on the horizon using GoogleEarth, I estimate 54 degrees rel N for one of the 2D sonic paths and 142 degrees rel N into the CSAT3 boom.  (These <should> be 90 degrees apart.)

I estimate that the mast was down from 1030-1110, then we messed with the mast height until 1130.

Conditions were snow flurries, T ~ -4C, wind 4 m/s.  Not great for this type of work!
