[Elecraft] K3S - K3 Noise Blanker and Noise Reductor

[Gian Luca Cazzola]

Don, sorry, but the NB doesnt work even on statics caused by rain or snow.
I really think that it doesn’t work well.
I tried it ON and with different settings, but in no way I could appreciate it.
If it work on impulse woodpeaker noise i really dont care: woodpeaker doesnt exist now. 
But today we have other radar noises on which the K3S doesnt work.
So it seem to me useless.
Also, the noise reduction of NR is really limited, I have not great results using  it.
But, please say me: on your K3 do you sometime need to use NB and NR? And how you regulated them in the menu?
Thanks
