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

Subject: [Elecraft] KNB2 Noise Blanker - doesn't?
I built, tested and installed KNB2 Noise Blanker,
in my K2 # 5422 - on 6 May 2006.
Still in the SWL mode, awaiting a stealth antenna, and
having gotten my K2 # 5422 aligned and KSB2 installed
- I've only practiced with using this
KNB2 Noise Blanker on noisy band (CW and SSB)
conditions.
The operation of the KNB2, in contrast to NB's on
various IC-706MKIIG and IC-7000 rigs I've recently
owned - doesn't seem effective at all. In fact I'm
doubting it does anything?
Today, a large propane truck sat outside, 50 feet
away from this K2 rig - plenty plenty of ignition
noise. Clearly, on 40m CW ignition noise - none
of that noise is reduced or eliminated by my
new KSB2 at all?
Aside from the simple hi/lo threshold settings -
is there any "alignment" tweaking which I could
do - to make this KNB2 come alive, and work?
And on my KNB2, the hi/low setting don't do
anything either?
Help & 73's
