Don,
Can this approach be used with the K2 in digital modes and if so what are
the suggested settings for the 'bars' when the ALC is turned on?

Snip
The K2 has operated this way all its life, but the K3 has a more 
sophisticated detection mechanism, so control can be more precise than 
the K2.  It still takes a bit of output time for the power to settle 
down, and that fact has caused a bit of 'wonderment' among users - if 
the response is too fast, the power level will oscillate because of the 
required high gain in the control loop, so it take a couple dit times 
(or equal for SSB and Data modes) for the power to level out.  The 
control loop is reset with a band change, and a few other actions that I 
cannot recall right now.
