K3 output increases running PACTOR

I recently began playing with PACTOR. I notice that I adjust the power
and mic gain to yield about 50 Watts and the output increases to75 Watts
or more in a minuteor so.

I set power to 95 Watts in CW, then switch to USB and increase mic gain
to yield 50 Watts, in order to avoid audio distortion. Is this not
agood way to operate? Is there a better way? Is there anything wrong
with the TNC or rig?

73, Red

Absolutely backward with the K3. As documented time and time again,
set the power to the desired level (e.g., if you want 50W set it for
50W) and adjust the mic gain (Line In level) until you see *five bars*
(four with the fifth flickering) and no more of ALC.

Red,

The K3 is not like "other rigs" which tell you to adjust the audio level
to control the power output. If you attempt that with the K3 (or KX3
or K2) you will experience "power hunting" as you describe.

Follow the instructions in the manual for DATA modes. Use DATA A
submode and adjust the audio drive to produce 4 bars solid on the ALC
meter with the 5th bar flickering (That is the onset of ALC, in other
words, NO ALC). - you may do that in TX TEST so you do not bother other
hams.

Once you have adjusted the audio drive, then use the power knob to set
your desired power level.
