Some of you were interested in what the Filters and such did on the K3 so I
wrote this little bit of information up to help you out. I hope you find it
useful. If you have any questions feel free to ask off the reflector. Thanks;
In brief:

Have you read column 2 of page 25 in the manual?
What it says is very close to what you have requested - except for
explicitly stating that 'some experimentation is required'.
It does say which noise sources the IF Noise Blanker is better suited
for, and which the DSP Noise Blanker attacks

At least for myself, it
There was "straight talk" about NR from Lyle Johnson (who designed and
implemented the algorithms) in his reflector posts of 8/25/09 and
8/27/09 as well as the information in the Firmware Release Notes for
version 3.30 (avaliable using the K3 Utility Help pulldown).
Page 25 of the K3 manual has
Excellent thread, several fine responses.
This is one for Wayne and/or Eric to weigh in upon with Elecraft concise,

"this is how to use the NB and NR."
Over to you guys!

Jeff,
I see you have gotten a few helpful answers. Let me add something to
your questions about shift and width.
The shift and width are mostly helpful for CW and possibly DATA modes -
the SHIFT centers your receive passband. A rough estimate of the
passband is shown in the lower left graphic
Thanks Gary and "The Smiths" (great 80s band, BTW!) for those very helpful
pointers! Can't wait to try those techniques out tonight!

I can help with some of these (though I'm clueless on the NB...)
It helps if you visualize the "passband" of the receiver as a small part of the
entire RF spectrum that the radio lets into your speaker (or headphone.) This
would be similar to a movable and resizable window on your house - so yo
Hi, I've been searching for some operating tips on how to strategically
employ the following K3 controls:
- NOTCH
- NR
- NB
- WIDTH
- SHIFT
As good as the manual is, I still feel like I don't understand how these
really work and when I should use them to get the best possible results. To
