[Elecraft] NB Verses DSP? Do I Need the Noise Blanker?

The KDSP offers Noise REDUCTION, but NOT an effective noise BLANKER!!!

The noise reduction is quite good at what it does, and that's reducing the
background noise during reception... but it's NOT a replacement if you need
a BLANKER.

As with just about any blanker, the noise blanker must 'see' the appropriate
type (characteristics) of noise before it can do a decent of of blanking it,
but when it DOES see the right noise, it will do a very nice job. It likes
to see repetitively-spiked noises, such as line noise, ignition noise, and
the noise your XYL's electric mixer or the neighbor's electric fencer makes.
