Saw some interesting behavour this weekend with the X50 on spec display. I came within proximity of a known K band sign (about 1/4mi perpendicaular, stopped at a light). At first I got a reading of 24.300 and then it flipped to 24.100. It did this back and forth for a bit and then settled on 24.122. Anybody seen this before? Normally I run in expert mode so this was the first time I came across something like this..
