After you've done what Bill suggested, try setting the loss (dB) for
this filter, using the K3 Utility program. I believe the equivalent
filter loss is 3-4 dB. This would be normal. The K3 can compensate
for it, as long as you set the value (otherwise assumed to be 0 dB).
Be sure the filter width and offset is set correctly. Easiest way is
to use the K3 Utility program.
