Hi Harvey,
This is for you. As I said before on this list, If you are having QRN, try
turning on the KNB2. On some types, particularly anoying kind kind that
sounds like frying bacon, it works superbly. But it doesn't work for all
kinds of QRN in my experience. No noise blanker does.
I always try changing the threshhohd as well. Most of the time I notice no
change, but sometimes it makes the difference between being able to copy a
signal and not. Of course, this assumes that your KNB2 is correctly built.
73,
John (W2GW)

Hi Bob. I tried switching the NB threshold and it has no effect on the NR
on my K2 s/n 5022.

Subject: [Elecraft] K2 Noise Blanker Problem (Feature?)
Hi Gary, I finally discovered what the NB was doing on every other
threshhold change. What I had perceived
as a drop in level was actually the DSP Noise Reduction being turned on
and off. Each time the NB is switched from
low to high threshhold, the DSP NR is either turned on or off depending
on its present state. I guess I should
consider this a bonus, since I only have to push one key (albeit twice)
for NR instead of pushing Display
and Band+. Now though, I'm wondering if this behaviour is unique to my
K2 or if any with both Noise Blanker
and DSP installed exhibit the same? You said you didn't hear any change
on yours when cycling NB threshhold, but
did that K2 also have DSP installed?
I'll post this to the list also - maybe someone else can verify whether
this is unique to mine or common to all...
