Hi Gary,
Please remember that this is a -beta test- release and not a formal
final K3 f/w release.
The purpose of any beta test release is to test new features and gather
constructive feedback. It is not something you should be using to form a
final judgment or complain loudly about, sine we

I'll also send this directly to Elecraft.
What I'd like to have is the ability to adjust through the various NR
settings without having to hold in the NR button then scroll through the
settings.
Would it be possible to have a menu selectable choice so that if RIT/ XIT is

I found the NR in v3.25 to be excellent to my ears and a big improvement to
previous versions, but I'm having a lot of trouble finding a NR setting with
v3.27 that I'm comfortable with -- everything sounds like it's coming
through a tunnel, even the x-1 settings. I generally prefer minimal DPS
Make sure and try it with AFX on and off.

With the 2.8K filter and using F/W 3.25, by far the best copy was obtained

Elecraft says they are planning on bringing that low end audio back as
a feature rather than as a bug. I'm very glad it was there as a bug

Did that, Brett - should have mentioned it in my last post. The tunnel effect
that I'm hearing is actually less objectionable with the AFX on.

Is it still the case that the interpretation of the NR parameters is

The manual states:

through noise reduction, from 1 (50%) to 4 (100%)
If so I'm confused by the identities:

Sure, I know what to do in practice, and I'm not looking for a one
size fits all solution. However, it's nice to know if the behavior is
