[Elecraft] KDSP2 versus KNB2

The KNB2 is designed to suppress pulse-type noise.  The KDSP2 is designed to
suppress background noise and heterodynes, as well as provide additional
filters.

The two products complement each other, but neither does the job of the
other.

So, you should have both for maximum effectiveness.
