[Elecraft] KNB2 Noise Blanker - doesn't?

[Fred (FL)]

On my K2's NB (KNB2,  May 2006) -  It seems no matter
what type of random, or periodic band noise is present
- activating the KNB2 doesn't affect the noise
in any fashion?  It doesn't get louder, or quieter,
or no noise goes away, and "noise" doesn't get any
better.

So I guess, besides the OK TESTS, when I built it -
it isn't working as it should.

I know when I built it in April or May 2006 - I
complained to Elecraft's support group - that the
KNB2's Circuit Board - seemed poorly made.  Almost
like whomever makes their boards, blew it on my
KNB2's board.  Elecraft offered to take it back,
but I built it and put in into service into my
K2 #5422.

I wonder if I couldn't send in just the KNB2 to
Elecraft's support group, for a checkup?

Thanks,
Fred N3CSY
