[Elecraft] NB effective?

[Merv Schweigert]

Heres one I really dont want to bring up as I have seen so many
reports of how effective the NB is on the K3. 
In fact one of the key factors that tilted me over the edge to buy
the K3 was reports that it had the best NB people had used. 

This morning the long silent (at least on 40 meters) Chinese or
whom ever buzz saw was on again.  Not the one that was called
the dragon but one that sounds like power line noise buzz.  
The NB on the K3 was not only totally inefective, but actually
increased the noise by several S units.   There is no setting of
either blanker that even touches the noise, and if using the IF
blanker as you increase the setting the noise increased also to
the point of at a setting of 7 it was 2 s units stronger. 
I have also had almost zero effect on power line noise which is
very similar type buzz sound. 
I turned on the other brand X radio which has two blankers,
a standard NB and a wide NB,  on either setting the buzz was
completely eliminated at a low setting of the blanker control.

Perhaps there is a way for Aptos to hear that type of noise and
twiddle software to make it work on the K3.
Sure need some major help on this one,  makes the 40 meter
band unusable when its on and the blanker does not work.
