[Elecraft] Compare: K3 to Collins S-line receiver

[Bill]

Discounting the digital capabilities such as memories, DSP, etc. and 
only considering actual signal reception: I have had S-lines in the past 
(dark dim past), so certainly am familier with them. However, as a point 
of curiosity, how does the S-line compare to the K3 (only interested in 
SSB). Basically, I am interested in how a top of the line analog 
receiver does compares to a K3(S)? The question comes from a QSO 
regarding the microprocessor noise of modern rigs covering and/or 
distorting received signals. Offline response might be good for this, as 
I am sure not many would be interested in the subject.

Thanks, Bill W2BLC K-Line
