Jim,

I'm sorry to say I don't know the answers to the spectrum question. The 
spectrum display is created by the KiwiSDR radio, and it does not 
display those specs like you see in Argo or Spectrum Lab.  I had no luck 
from a search of the Kiwisdr User forum. I think it is a question for 
the developer.

I will say the waterfall has a rate control (slow, medium, fast), but I 
think that is simply the speed at which a new line is painted. I don't 
believe any integration is occurring.

I have had the radio for a little over a month, so I am still learning 
about it myself.
