[CA] [CA11] Wind readings become incorrect after a few hours of sailing

[Adventurous]

Hi Chuck. I have a similar problem, however it is intermittent, and corrects itself at some point, typically after I have re-calibrated.
I display in Apparent on the ST60, and every so often the Axiom (apparent wind on the compass rose on the sailing data page) and ST60 wind will both be in error by about 60-80 degrees from the masthead wind indicator. Reboots didn’t ever fix the problem, so now I immediately re-calibrate on the ST60. At some time down the track (hours or days) it corrects itself, and displays the error in the opposite direction. I then have to re-calibrate again. It doesn’t happen that often, but as a full time cruiser, it’s a pain.

Any thoughts please?
