[Elecraft] K3: pwr out - does this sound right?

[Don Wilhelm]

Doug,

You are testing the regulation capability of your power supply.
I would say that is fairly normal - most of the drop will occur in the 
initial part of the I-V output curve for the PS, then will flatten out 
as the current becomes greater.
You are indicating a regulation of 3.7% over that current draw range 
which is quite good.

73,
