[Elecraft] k2 noise blanker

[Jack Brindle]

The noise blanker on my K2 is _very_ effective at eliminating the  
power-line noise in the area. Many time with it off the noise level is  
around S9 or higher and unless signals are very loud I just can't hear  
them. Turn on the NB, and the noise disappears and I hear signals.  
When I first got the K2 with the NB several years ago I had the same  
questions as you. Then the power-line noise problems started, and I  
quickly found out. I just wish whoever is responsible for the PL noise  
would be just as responsive in getting rid of them...

I haven't found the setting yet  for the K3 blankers that provide the  
same effect, but it should be there.

Keep looking at various periodic noise environments, you will find a  
use for the blanker.
