I noticed today that a had a few, small white spots on my green painted map.  I got to watching the direction arrow and noticed it would try and flip momentarily.  I unhooked the radar to see if that was causing any issues, but didn’t change.  I watched my row clutches in the diagnosis page and didn’t see any rows get a white box around it, indicating the clutch was momentarily shutting off.  The tractor is a Case Magnum 275 with 372, NAV II and Pro 700.  Radar signal stays stable and GPS signal appears to stay locked onto RTK.  Any other ideas?

Edit:  baud is 38,500 and the GGS and the other two are set at 5 hz.
