I arrived about 9:45 with Siyan. It was warm and sunny with some high thin clouds. There was almost no wind when we arrived but there was a little breeze from the west when we left. Everything is very dry. Tonzis pond is just a mud puddle. There were lots of animal tracks in the dust on the road. The trees still have some leaves but they are mostly brown and waiting for some rain to knock them off.

I put the tram back. On initial start up it stopped and started a bit. Tapping the box got it running smoothly and led me to think there was a loose connection some where. It completed one pass successfully and then I checked all the screw terminals. The only one that was loose was the ground on the CR10X power plug. The tram ran again later and data was collected by the tower computer.

I serviced the z-cams.

I swapped the 7500 on the Floor - sn 0041 came off and sn 0976 went on. Siyan swapped the 7500 on the Tower sn 0073 came off and sn 0035 went on.

I replaced a spade terminal for the 7500 analog lines in the Tower PSU box with a screw terminal and fastened the power terminal to the back plane.

I reinstalled the LED sensor. It was a real pain getting the cables through the split loom most of the cable ties broke being brittle from sun exposure. I put the LED data lines back on the AM16/32 in differential mode, but jumped the common low to the analog ground.

I cleaned the Tower top radiometers.

I forgot to turn the screws on the tipping bucket 1-1/2 turns CW.
