[Elecraft] Noise Blanker

[ron]

Hello all;

I push on a CW "filter" and it does the same thing!
I also press attenuate with same results!

Unh? Noise blanker and/or filter does same thing?

Why?
Because filters and NB may "appear" to remove atmospheric noise, but 
it's still there, because it's attenuated. (There's a little more to 
that but not here)

Noise blankers work more effectively on man-made noise such as 
automobiles, lights, motors, hair dryers (pulse type noise) etc.
Not atmospheric noises.

Oh,
after you did that, you probably had to turn up the volume a bit 
like I did.
It make for easier listening though.

Regardless, I love me K1.
