[Elecraft] K3 noise reduction

Continuing from my previous message -- I just loaded the current  
Firmware 2.02. I think NR works better now, but I'm not really sure.  
In the process however, I found that I was being distracted by the  
more "powerful" ranges of 3-x and 4-x.

For SSB, the best setting seems to be "1-3". Before, I didn't think it  
was so effective. The 1 range maintains good volume equalizing between  
on/off. Higher ranges cause too much distortion. Maybe they are OK on  
CW, but any advantage seems to be not worth the time to continue  
experimenting. For now, I'm going to use "1-3" and forget about the  
higher ranges of NR.

A good improvement would be if the NR processing could reduce  
automatically with signal strength, to avoid unnecessary distortion on  
strong signals. I trust we'll see some further improvement eventually  
but meanwhile, I can enjoy using it on low signal/noise ratio  
conditions and switching it off on stronger signals.
