[ARC5] Sweating the detail - "Q" {was apples and oranges}

[Leslie Smith]

  Hello List-readers!
  Writing in the context of attention to detail, but involving "Q", not
dB and hearing levels, I want to mention a web-site that impressed me a
good deal.

  Start here:  http://www.crystal-radio.eu/index.html

  Then choose either dutch or english language and experiments with
"experiments with LC circuits".
  These pages describe a well-thought-out set of experiments that seek
to improve "Q" (decrease losses) and record the improvement gained -
from a lowly "Q" value of 150 or so up to a "Q" of around 1000.    The
page that impressed me most discusses "ripple" observed on the CRO
during measurement - an audio 'beat" between his lab equipment and a
distant powerful transmitter leaking into the experiment.  How many of
us would have noticed this detail, and taken the trouble to
investigate.  This is surely science at it's best!

  All this proves what you say below, Dennis - that if you don't sweat
the detail you probably won't get the best possible result.
  In these experiments each improvement is only a few "Q" points - 20
here, 100 there - but in the end the result is both instructive and
impressive.
  I wish I could think like this!

  Dennis - thanks for you posting.

It does make sense, Bruce.  A lot of sense.  It's a human behavioral
thing.  If you don't sweat that detail you probably won't sweat the
other two or three sub dB details either and that will eventually add
up to something that truly matters.
