Another sunny day. We split up today, with John and Liz heading to Sedgwick to work on the ISS3 wind profiler, and Gary, Lou & I to work at ISS1.
John and Liz did a lot of testing and switching around of equipment to diagnose the wind profiler issue. This included swapping out all of the electronics with the ISS2 profiler and other tests. The quick summary is that there is a problem with the switching relays. It is not clear how to fix it, so they are considering their next move.
At ISS1, we got the wind lidar connected and running. I ran it for about 3 hours using the old database (at CFACT in Utah, the database on the internal computer became full and would not clear which caused difficulties running the system). I then performed the factory reset that the manufacturer had suggested (and had warned might take 3 days and might not work). Fortunately the operation went much faster than expected and how the system is much more responsive and has plenty of space for SWEX. The air is fairly clear so returns were somewhat limited, but with a 100 m pulse it was seeing 3 - 4 km horizontally at times, although less with the 50 m pulse. We also leveled the lidar trailer, worked on networking, system updates, reran some power, and started installing cameras. The Modular Profiler continues to work well. In the 2.7% duty cycle mode it is giving winds to 3 - 4 km AGL. It's drawing 2.60 A on the 50V and 1.671A on the 31V supply.
