P-T,
If you follow the instructions frequently given on this reflector, you
will have proper power control and no flat-topping.
For soundcard Data modes, monitor the audio input level on the ALC
meter. You should have 4 bars illuminated with the 5th bar flickering.
The first bars of the ALC meter do not actually indicate ALC - the onset
of ALC is at the 5th bar, so the lower bars are used like a "VU-meter"
to aid in adjusting the audio drive level.\
The closed loop method of power control used by the K3 requires that you
fully drive the audio and use the power knob to set the desired power
output. Attempting to control the power with the audio drive will
result in "power hunting".

I found the problem.
Increased the settings of PSK/FSK Level in RMS Express TNC Setup to 600.
Now I've got full power out from the K3.
Guess I'll have to investigate proper MIC setting in order to avoid
flat-topping etc.
