[Elecraft] KDSP2 and KNB2 together

Hello,

I was wondering if the esteemed field testers tried combinations of the 
noise reduction filtering in the DSP with the analog noise blanker. I wasn't 
sure if the combination would play together well or if that might be too 
much signal manipulation. If it's better to use one or the other, then I 
would think the analog noise blanker might still be the preferred method for 
some repetitive noise, allowing the DSP to concentrate on bandpass, 
auto-notching etc.. Any thoughts?

p.s. A little off-topic question: I am moving back to "9-land" Indiana at 
the end of this month so my callsign will be legitimate :) (Well the real 
reason is opening a hobby shop) Anyway, I have heard comments made on 
reflectors about 9-land being an "RF black hole". Has anyone else heard this 
and have any word on if there is some truth and if so, why? I am trying to 
understand propagation better, but my memory is such these days that I have 
to keep relearning the same information :)
