[Elecraft] KNB2 Noise Blanker Problem?

[Van W1WCG]

Greetings all,

Just finished the Noise Blanker for the K2.  In trying it out, I can't =
see that NB1 makes any appreciable difference
to a high AC-type noise level, although the NB in my FT-1000MP knocks it =
out fairly well.  NB2 somewhat attenuates
signals and noise about equally.  Changing the threshold makes no =
apparent difference. I'm afraid there may be
a problem with the KNB2.  I've checked all the solder joints (reflowed a =
couple of 'em) and made sure components
were properly placed and oriented.  Question: is it normal for the the =
NB-2 mode to somewhat attenuate everything?  Has
anybody else had the same type of problem and found a fix for it??

TIA,

Van, W1WCG
