[Elecraft] K3 vs. Icom IC-7600

[Wes Stewart]

First let me say that I once owned and Icom IC-211.  It was such a POS  (using solder bridges between IC pins instead of circuit traces for example) that I gave it to a friend who also had one.  I often said that it was a measure of his character that he accepted the "gift" and we still remained friends.  So I am no friend of, or apologist for Icom.

That said, why would the second mixer in the Icom be any more susceptible to overload than the second mixer in the K3? (Disregard the other evidence that the Icom 3 KHz filter isn't really 3 KHz.)

Unlikely since thy use a high first IF with their narrowest roofing 
filter at 3 kHz. signals inside that filter will overload the first 
mixer and subsequent stages, well before any later crystal or DSP 
filtering can do any good.
