That is interesting; but mine has been "professionally calibrated" :-)

    I played clarinet in the 6th grade -- hated
    it.  I was a mathematician (programming a lot
    of mathematical applications and other
    things).  And I still love mathematics because
    Mathematical Physics is my primary hobby
    (or, passion).  Ham radio comes second except
    in the summer ham radio could count as third
    to woodworking as second.

    I learned CW when I was 9 years old.  By the
    time (much later) when I took my Novice
    test, I was probably copying more than the
    13 wpm required of the General class.

    This is off-topic so far -- but my tone
    frequency of choice is 640 Hz.
