Obviously you've never operated a contest with a neighbor running an

There are no bad radios currently on the market. Some are better
radios, but better is in the eyes {ears} of the beholder. However,
those radios of yesteryear, as compared to the current breed of radios

While I appreciate the input from Wayne on the K3's programming
architecture (as well as the facts on the power consumption
characteristics), the reality is that many of us have identified other rigs
that have implemented NR in a way that produces results that are much more
satisfactory. Comments

So you can run it from a solar panel after the aforementioned disasters.

The K3
The K3's DSP code is written in very efficient assembly language. It executes
quickly, because it doesn't need the lengthy library-routine calls typical of
the C or C++ code written for GHz-clock DSPs. The code is also extremely
compact.

Some how I just am not all that impressed by those "fantastic" DSP
numbers. What does impress me is the absolute quality of the received
signals presented to my ears by the K3.
In about 55 years, my K3 is the most satisfying receiver I have ever
used - and I have had most of them along the way
It reminds me of my computer overclocking days when bragging rights went
