[Elecraft] Understanding the KX3 Block Diagram

[David Stratton]

Hoping that I may not be the only Ham puzzled by the block diagram of the
KX3 I am asking that someone please explain it because it is so different
from the superheterodyne radio concept I have become accustomed to in
current amateur radios. I understand direct conversion radios but what is
all the stuff that's there besides the mixer-oscillator and audio amplifier
needed by a direct conversion radio? It seems to me the KX3 block diagram
looks a lot like radios put forth some time ago by Rick Campell KK7B. Pardon
my saying so but the KX3 radio looks like it has a weak front end and a
heavy back end that hopes to make up for the weak front end!
