*Dr. Coleman - I beg to differ with you on that point.  If you file off
the ends of the fork you will only be RAISING the frequency of the fork
as the tines become shorter.

......If it is too flat, file off the inside edges near the base of the
fork. 

*Likewise, filing off the inside edges of the fork causes the frequency
to lower - therefore causing the fork's pitch to become even flatter.

VERY Respectfully,
