I just saw this RCA rotor on sale, I don't know that is is precise enough, because it is programmable for every 10 degrees. I haven't read the manual
far enough to see if you can precisely set direction to null your noise sources or if you can fool it to ever 5degrees by only turning 180 degrees.
It is $89 on sale with rebate.? $14 shipping, at least to me in Fl.

Here's the manual,
