OK, Martin, I am not going to argue.  My first encounter with the term 
was when my Elmer, W2OKE and an EE, referred to it when I was 16 years 
old.  At first, I thought he was joking, and the vision of buckshot 
raining on a tin roof came to mind.  Some time during the next 50 years, 
I have a vague recollection of coming across the term in a text or other 
technical source, seeing it spelled as Schott and saying, "Oh, yeah, 
that's what Bob was talking about."

I just did a search on the Web, and found references to "Schott noise." 
It is as I described and obeys an Arrhenius relationship, as you said.  
It is spelled "Schott" though.  OTOH, I should have said either "White" 
or, as I have now discovered, "Gaussian" noise.  "Schott" was the first 
term that came to mind because it had been etched into my brain as a kid.

Sorry for the gaff on my part.

73, Joe
