[Elecraft] KNB2 Noise Blanker - doesn't?

[John Reiser]

Hi Fred,

My KNB2 works superbly on a certain kind of noise that I only get once in a 
while.  I don't know what causes it, but it sounds like frying a big pan of 
bacon.  It's a nasty crackling sound.  The KNB2 takes it out completely. 
I'm building my second K2 right now, and of course, it will have a KNB2.

Hope this helps.

73,

John, W2GW
