That's it - you must turn compression off, one of the virtues of DATA A is that it does this for you automatically. With compression off it should work fine.
See pg. 31 of the K3 Owner's Manual where it says: "Soundcard-based data communications can be done using LSB or USB mode. However, DATA modes offer several benefits not available in SSB modes. If you prefer to use LSB or USB, you'll need to manually set CMP to 0 to prevent data signal distortion..."
