[Elecraft] Setting bias current on KPA-100

[Doug Person]

How important is it to set the bias current accurately.  None of my meters
seem to do very well in the necessary range.  They all tend to go 0 to 200ma
and then jump to 10 amps.  At the higher setting resolution isn't very good.
I think I'm OK and near enough but wonder whether to err over or under.

I also notice that KPA is very sensitive to SWR.  It starts to back down
power at 1.5:1 or more.  Are the finals really that sensitive?  I notice too
that the fan doesn't seen to run much.  Is it better to set it so it runs in
slow all the time? Or is it fine to just leave it in the normal position?
