[Elecraft] Will the K2 noise blanker help with this QRM?

[Don Wilhelm]

  Chas,

The K2 noise blanker works well on impulse type noise (like gasoline 
engine impulse noise or lightning static), but it is not effective on 
noise that has a slower rise time such as general atmospheric noise.

I would suggest the KDSP2 noise reduction algorithms as a potential 
better solution for the noise you are encountering.
