On the K3, the VFO B knob may be used to select voltage, amps, time, etc. To
determine what the power draw is for portable operations, I connected a
multimeter in series with the supply and measured amps at various stages,
hence idle (receive), key down for 5 watts, 10 watts, etc.
At idle my K3 draws about .92-.94 amps, verified by two different multimeters.
However the reading on the front panel when selected with the VFO B knob,
shows .71 amps.
So, I am wondering just what it is measuring for the .71 amps and is there a
method for calibration if it is supposed to be measuring the total power draw
from the power supply.
This is not that important to me, but was rather curious about this.
