Lyle's guidance is on the mark -- after all, he wrote the code, so he 
knows what it does!  

In CW mode, I'm nearly always working at bandwidths less than 400 Hz, 
and I've rarely found NR very useful In SSB mode, NR greatly reduces 
the noise when there's no signal, so it allows me to crank the gain 
higher when I'm just monitoring or tuning arond, without a lot of 
fatigue from the noise. That's a good thing, but I've not often found  
situations where NR improves the readability of a signal. 

On the other hand, I DO find that the Noise Blanker helps if I don't 
overdo it, and also find that it's easy to overdo it. :)
