As Don has pointed out "Note carefully -- for the KX3 (and K3) in data modes, the "ALC" meter is also used as a level indication. Adjust the mic gain to produce 4 bars on the meter with the 5th bar flickering - that is the NO ALC point.The 5th bar indicates the onset of ALC." >From Fred Cady's book Page 101 "Adjust KEYER/MIC to set the Mic gain for a peak ALC reading of about 4 bars. The ALC meter is actually acting like a VU (volume unit) meter. The onset of ALC is about the 5th bar so you should stay below that level. You may have to adjust the sound card’s Line Out or Headphones Out to achieve the peak ALC reading of about 4 bars. Avoid going higher than about 50% so that Line Out or Headphones Out do not clip. You would like to have the Mic Gain setting about the same as that used for SSB transmissions." I think this is where Don's suggestion helps is in adjusting the levels for increased sensitivity.
