Perhaps an explanation of how NR works will help you understand what you

it can define as a signal, and then builds a filter around it. The type

Indeed, this is a very subjective issue. One issue though that many will

I'm still getting my sea legs on the K3 but NR seems to work really great
on CW but on SSB, I can't use it. With it on, regardless of setting, it

Hi James,
I'd have to say that your post and the links to what you consider

This is a good example of just how subjective improvement can be.
Sure, the hash is gone, but it's replaced
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
