Living in Hawaii gives one a real opportunity to test the NB on the 
Hainan radar on 40 meters
and other freqs as well,  my K3 #26XX has never been able to remove the 
pulses,  I can
 compare to a couple of other brand X radios and one of them removes the 
pulses
very well, the other only so - so.    So operating 40 meters when the 
radar is on, requires me to
turn on another radio to be able to use the band.  
I figure it takes a special set up of timing and algorithm to tackle the 
Hainan dragon.
