[Elecraft] DSP Noise Reduction and contesting

[Arie Kleingeld PA3A]

Hi Pete,

The NR of the K3 is not a feature that shines. That's why I never tried 
it in contests. But in a few weeks there's the CQWW CW again. Maybe I 
will give it a go.

My two cents worth on the NR of the K3.
When applying NR I woud expect a better S/N ratio of some kind on a 
weaker signal (that's why it is called NR). On SSB I never found a 
setting that increased the S/N ratio or readability of the signal to MY 
ears (settings F5-1 to F8-4)

CW works better (F1-1 to F4-4)  but I seldom use it. For good S/N ratio 
I rely totally on the K3 filtering with APF as last resort. The only 
time I really loved the NR, was when I worked on 160m in the 9L5MS 
dx-pedition (in tropic thunderstormy Africa) for the whole night. It 
kept the fatigue of constant static noise away.
