Let's see....

The first step in the firmware upgrade should be to save the current 
configuration in the event that there is an unanticipated adverse 
outcome.   Reader of this list can recall many examples.

Saving the current configuration is the first step in the case of the 
prudently skeptical user.  I am one of those users.  There may be few 
among us K3 owners.  My view is there should be more of them.

This first step must of necessity be performed with the then existing 
firmware installed in the K3.

So, my question to you Dick is:

How do I get the 'current MCU revision' loaded into the K3 without 
ignoring the configuration save step?

...and then there is the first principle of software engineering:

     "BACKWARD COMPATIBILITY.  Subsequent releases are always fully 
compatible with all previous releases."

Perhaps that plaque needs to be dusted off and put up over the entrance 
to Elecraft.
