Don,
Are you using DATA A mode (AFSK A for RTTY)?
You may have difficulty like that if you are running in SSB mode with
even a little compression enabled.
DATA Modes automatically turn off compression and TX EQ.
Is your soundcard line out cabled to the K3 Line IN jack? If you have
it plugged into the rear panel mic jack you would have excess gain in
the K3, use LINE IN.
Most users seem to have good luck with the soundcard line out set at
about 75%, but some soundcards do have a bit more output than others.
You do want to run the soundcard in the upper range to produce a better
S/N ratio.
You may have to settle for the 3 bars with the 5th flashing.
The flashing 5th bar is the onset of ALC, so you should not drive the
5th bar solid.
73,
