Firstly, that's one of the most aesthetically pleasing ISS sittings I've seen, almost looks like a lawn sculpture (well, at least to this weather geek).
So, when you say "moved", where was it before, on the roof? How long have you had "wild swings" and what do you base that on? Also, curious why you have a DFARS cover on your transmitter box with a 24hr ISS?
