Something missed in this discussion.
When you change a NB/NR setting, don't expect a instantaneous change.
Count to five and then conclude whether a setting change helped or not.
In some past posting, this was pointed out by Elecraft.

Arlen,
One thing to keep in mind regarding NB and NR is that only the NB can
actually (sometimes) reduce the noise floor to the point where you will be
able to hear weak signals that are far below the noise floor that you
would have when NB is NOT engaged. In other words, when engaged and
There is no 'secret recipe'.
As has been pointed out by several others, the NB settings must be
adjusted to best deal with the noise you are encountering at any given
time on any given band. Also, when dealing with the DSP based Noise
Blanker, give it a little time to build the filter that
Greetings Elecrafters,
I’m new to the K3 (and HF in general), and I’m trying to sort out how to get
useful results from the Noise Blanking (NB) features.
I’m looking for strategies, tips, techniques, etc. for selecting the settings
for NB. With over 14,000 possible settings between the IF NB
As no one has responded yet, I'll throw in my most recent experience:
I assume you meant to say Noise Reduction - a mistake I made a couple of
months ago. Although I was quickly informed of my mistake, I never did
receive any really useful information regarding the many settings
available on
Hi Arlen - I, too, seek just such a general guide for using the
various noise reduction features on modern transceivers, but have yet to
find one. Transceiver user manuals are typically pretty lean on real
world explanation - they enumerate the features, point out what button
or knob makes
I'll try. The short answer, in case you're not into an explanation is:
It all depends on your circumstances, the character of your noise, the
strength of the signal you're trying to copy, how much distortion you're
willing to tolerate ... and sometimes the phase of the moon. No one
can give
Fred Cady's book has more the approach you're probably looking for.

Have any of the Field Testers with working K3s had a chance to
look at the combined performance of the hardware (firmware?)
and DSP noise blanking abilities to suppress key clicks from
other stations?
During some contests, that would sure be handy.
Thanks and 73
