[Elecraft] K3/K3S noise blanker performance greatly enhanced (at my QTH) -- need testers

[drewko]

I'm glad that noise solutions are being investigated. I think advances 
in NR/NB would be of more importance to many hams than close-in dynamic 
range, however useful the improvement in those attention-getting figures 
are. On a day to day basis noise is the top culprit for many of us.
