I noticed the compass jumps back and forth by about 5 degrees for no clear reason, as if it is using two different sources for direction. It is really noticable when attempting to calibrate to the bow after moving the SCX-20 to a new location on my boat, however I suspected this was happening in the prior location as well.
I confirmed this by tying the boat to the dock and watching over a period of two hours it went back and forth three times between 109 and 114 degrees, the same two directions. Changing sat constellations made no difference. Setting to US only for example. Choosing elevation 30 did not make a difference. The SCX-20 plot is showing many sat's are observable.
