[Elecraft] Regarding the K3 and high QRN levels

I'll probably get lynched for saying this, but for my ears I've never found 
a DSP system that is as good as a pure analog system when there is rough 
noise. The K3 is much better than my Orion I, but I strongly prefer full 
analog IF's with rough noise or when a signal is right at noise floor and 
the floor is a little rougher than white noise.

To me it sounds more like a little intermodulation or mixing of the noise 
and signal.  I've even considered building an analog IF system just to see 
if I like it better. :-)
