I'm running version 3.27/2.25 on K3 #384. I live in a high noise suburb of NYC. When I tap the NR button, the noise just about disappears, and the signal remains, SSB or CW. Magic!
The difference is more noticeable on SSB, of course, because I usually have the pass band set to 500 Hz for CW. My favorite NR setting is F1-3. I seldom change from that setting anymore. I don't use EQ. I operate 90% CW and RTTY. When I do operate SSB, I'm not too concerned about audio frequency response. If I can understand what the other guy is saying, I conclude that I've got him tuned in OK. When I want hi-fi, I get out the IPod_ hi! But, don't be mad at me. That's just me. I respect all differing opinions. Maybe I'm just not as discerning as some folks. 73, John, W2GW ----- Original Message ----- From: "N2TK" <tony....@verizon.net> To: <elecraft@mailman.qth.net> Sent: Friday, August 28, 2009 6:10 PM Subject: Re: [Elecraft] K3 NR > Yeah, I agree with what you are saying.
