[Elecraft] K2/100 power-out change

[Tom Hammond]

It IS in the software ALC... reflects the ALC's attempting (at about a 
1-seconds rate) to 'stabilize the output at the requested power level...

Seems I recall there being a fairly simply remedy to this problem... at 
least to remedy MOST, if not all, of it.

If I recall, it was the addition of a cap somewhere, but (unfortunately) I 
don't recall where.

Double check the archives, or maybe someone will offer it up.
