[Elecraft] K3 on-channel strong signal overload?

Yes, but then you'd mask the weaker signals underneath.  Anything that 
requires computation, reaction, and delay (variable or otherwise) to 
stretch the dynamic range is a non-linearity of one type or other (time 
or level or both) that negatively affects the signal handling ability 
(either in terms of sensitivity or distortion) somewhere within its range.

The thing that puzzles me about this entire thread is ... why do people 
want to take a world-class communication rig like the K3 and make it 
function like an FT-817 or a BC-455 or a Hammarlund Super-Pro or a Radio 
Shack Scanner or a 1940's radio for listening to NPR?  Did people buy 
the K3 simply because it was the "in" rig without considering what they 
really needed?  That's like buying a race horse to plow a field.  If 
someone wants to do that, that's fine with me ... as long as they don't 
mess with the breed to turn that race horse into a mule.

I'm honestly puzzled by some of the comments I've seen here lately ...
