[Elecraft] NB/NR Noise Blanker/ Noise reduction

[Steve Ellington]

This is amazing....We have some who complain about NR increasing the audio 
and some complaining about it reducing audio!
I think the K3's NR is the best I've seen thus far. Contrary to some 
"experts" opinion, it works great with narrow cw filters and not only 
reduces noise but "Peaks" the CW signals. Someone said it makes CW "mushy". 
I say it does just exactly the opposite. It sharpens the AF response and 
enhances CW, especially weak signals that are down at the noise floor.
Have had a lot of rigs, the IC-7800's NR is pretty good too. The PRO series 
NR is terrible. Keep in mind I'm talking about CW here. Keep that AGC 
threshold up high and the SLP low....It makes the NR really bring up those 
CW signals nice and LOUD like they should be.
