David, I am a mostly CW operator with only an occasional SSB contact or contests. I find that I can copy signals on my K3 that I cannot copy on my TS-850, but only a few very weak ones. The most effective control against noise that I have found is the Width control and in 160 and 80 meter very noisy contacts I find myself at 50 or 100 Hz width. I find that the signals all sound noisy unless they are very strong, above S9 which are rare in today's propagation. I can make the signal sound a bit less noisy with the NR, but at the expense of copy ability, especially with code speeds above 20 wpm. I have never found the NR to be useful for a CW contact. SSB contacts, even with a setting of F1-1 are distorted enough to be difficult to copy. For noisy SSB contacts turning off the AGC and reducing the RF Gain seems to be the effective tactic.
I have been reading what people have to say on this forum and I get further confused about how to properly set up the AGC, NB and NR to make them work to my advantage. I find both of my 20 year old Kenwoods more pleasant to use (a TS-440 and TS-850) but I can work signals with the K3 that I can't work with the others. The NB is more effective with either of the Kenwoods. I still think I am doing something terribly wrong with the K3 and I need more contacts to figure it out. It seems that only 2,000 or so QSOs is not enough. I need more experience with Ham Radio, perhaps. Fifty three years does not seem enough.
