[Elecraft] K2/100 ALC

[Anthony Bowyer]

  I have a k2/100 that I want to be sure I understand
how the ALC should work.

  It seems it is more responsive than reactive; that
is power is increased if allowed, up to the maximum
rather that diminished from maximum as a response to
some factor, such as high SWR.

  When I first power the K2 on, if I send a series of
fast dots, the ALC seems to respond very slowly to
bring the power up to max. It's faster with dashes and
very fast with a dead carrier. It will basically
remain at full power then unless the SWR changes or
something similar, until it is powered off and then
back on, at which time it goes through the same
process.

  Is this how it should normally work? 

  The reason I want to be sure is because this k2 had
some damage from the wrong cable plugged in at the
DB9. I found components damaged on the KSB2 board but
everything else seemed to be fine. 
  I removed the KSB2, jumpered the correct connections
and put the capacitor back in and CW is working
correctly; just this ALC behavior is a little
different than I'm used to. I want to be sure there's
not another component bad in the ALC circuits
somewhere.

Thank you!
Anthony, NT4X
