I set everything back to the default settings. Then the only ones I
ended up change was the SSB & CW gain settings. After that, when I
want to use the DSP, I would step through the different "freq widths"
that are supplied by S1(NR1, NR2, NR3, NR4), then S2(NR1, NR2, NR3,
NR4), and so on. This is the piece that I did not "get" the first
time around.
My initial tinkering had focused on the settings you mentioned. But
it seems to me, that tinkering with Beta and Decay, before you have
worked through the existing setup, that is the application of the
various filter widths to you problem noise, is going about the process
from the wrong end. Perhaps Lyle can explain it better.
I hit DISPLAY to get into the DSP settings, usually C1 .nr (for CW) or
S1 .nr .nt (for SSB) is seen at this point. If not, press RCL
untill one of them is visible. Then pressing STORE brings up C1 .nr1,
pressing STORE again, brings up C1 .nr2, and so on till you are back
at C1 .nr1. If I do not find a suitable setting in the first 4 filter
settings, I then press AFIL to take me to CF2. Now pressing DISPLAY
followed by STORE brings up C2 .nr, and I can go through these steps
again. This cycle can be continued through CF3 and CF4.
In performing these steps, I have not needed to fiddle with Beta and
Decay. I assume and changes to Beta and Decay, impact all 16 filters
per mode.
Hope this helps. It sure made a big difference in how I use the radio.

David,
Can you shared the settings you settled on, by mode? Especially include the
Beta and Decay settings.

Subject: [Elecraft] K2 - DSP - Impressive
I have had the DSP for the K2 now for some time. I have to admit, I got the
instructions out the first couple times I played with it, but I did not
quite "get it" as far as the settings and the menu choices, and just kinda
left things alone.
Over the intervening weeks, when I would get on SSB to chat with friends I
kept tinkering with it, and trying different settings (it didn't really seem
to need to be fiddled with on CW). Eventually I had the thing so screwed
up, that it was more of a hindrance than a help.
So I broke down and printed out a section of the manual (I'm more of a soft
copy kinda guy, but don't what to start that thread up again) and sat down
at the radio to try and get the DSP back to all of its default settings.
Now, as it turns out, reading through the manual, it is not abundantly
obvious (for some of us denser folks) how to do this, but when I read a bit,
and tinkered a bit, I worked through it just fine. Except for SSB #1 and
the LowPass settings, I couldn't make that happen.
Once I worked through all of the settings for each filter setup, I learned
quite a bit. As many have said before me, this is a VERY impressive DSP. I
did not fully understand the capabilities and settings till now. It is
definitely worth the investment of time to learn.
I even broke down and read through Lyle's "Design Considerations for the
KDSP".
As always, great stuff. Thanks again Elecraft. Not only do you supply
great equipment, but your documentation gives explanations of how the
equipment works, thus we become more knowledgeable operators. Thanks, and
great job!
