Pretty well covered by others.
One more fact to consider is the K3 is a SDR which means the firmware
can continually be improved or embellished, thus keeping the radio
from obsolescence. The promise of SDR is that it can continually
re-invent itself with new sw (firmware). With ten years under its
belt a lot of ideas have already been incorporated. Recent
improvement in AGC is an example of continual product
improvement. Elecraft is the only organization I see this coming
with any regularity. The typical mfr rolls out a whole new piece of
hardware requiring you to dispose of the old radio and spending a lot
of money on the "new stuff". Have you noticed that Elecraft new
firmware is free!
In time the hardware is replaceable with new technology, so
eventually there will be better components for building SDR's and
that might lead to a successor to the K3. In a manner of speaking
the KX3 is that.
I hope the idea of replacement through new modules is followed. That
is where a radio built with daughter boards on a master mother board
is more amenable to hardware upgrades. The tradeoff is reliability
issues with daughter board connectors (over time).
Those of us that like to experiment with new stuff like the modular
approach. Think of new firmware as new modules!
