I observed an interesting symptom of my APRS installation where it shows position reports all over the place quite a distance away from where we were in reality. It creates a very ugly track on the map. I had seen this before but never thought a whole lot of it until the latest flight:

After thinking about it more, I can directly correlate the bad positions to time periods of moderate turbulence. This flight for example was in very smooth air to the east of Georgetown. However, later, to the west of Georgetown out at Lampassas it was very bumpy. I'm going to go out and see if I can secure the GPS connector better with a glob of RTV or something.
