[Elecraft] KNB2

[David N.]

Ok I have gone over my KNB2 Board twice now to see why
it will not blank any noise. I had a friend of mine
come over here with his and we used my noise source. 
(1948 Ferguson Tractor) Noisy ignition. He set his for
nb1 and badda bing badda boom all gone mine still
there. NB2 Still there. I asked hime if he did
anything to his and He said nope just the way it came.

I did research through the archives and found a note
about scratching the surface of Q22 But that is not
possible on mine it is under the NB2 Board. So What
can I do to troubleshoot mine.
Thanks
