        Hmmm...in trying this with the 100-110 Hz DSP
filters, I noticed a rather drastic gain change (-18 dB) as I
adjusted taps from max to min (199 to 32).  There is a very
noticeable +6 dB jump from 104 to 99 and then back down
from 99 to 94.  Tuning off-frequency, I believe I can tell the
shape factor changes, but the gain change makes it difficult
to tell what is really happening.  Think I'm going to stay with
199 for the time being.

73, Bill W4ZV
