  Carl,,, this is kind of off topic, (my reply, not your post, that =
is..) =20

      Practically speaking, yes, sometimes the SAT isn't picking up what =
it needs where it sits, and you have to adjust it's position. It's the =
same for all the Accu-tuners, by the way. =20
      Your post reminds me of radio, or electromagnetic radiation. The =
higher frequencies, like micro-waves for instance, don't bend around =
corners, even around the curve of the Earth. The lower frequencies go =
every which way.  The rules of wave propagation are pretty much the same =
whether it's light or sound, I believe..

  Kevin.

    Another factor could be (i'm just speculating) a bounce off the rim =
at a particular angle that would cancel with another one and if they =
were out of phase shifting the position would then solve the problem.

    John Ross tipped me on how to get around this, but curious why
    it happens. Occasionally a " note", and not the same one, will not
    activate lights unless I move Sat. to another location on piano. I
    have my own theory as to why it happens, but wonder if someone
    has the definitive answer. I'm not sure how to "splain" my theory,
    but it's based on why you don't hear tweeter signals from a high
    fidelity
    speaker if you stand to the side, where bass signals are heard quite
    readily in most any place you stand. High , or tweeter sounds are =
very
    directional as opposed to low frequency signals. What say ya'll.
