I usually use FSK for RTTY, but I switched to AFSK to test this - I
can get anwhere from 7 down to 3 bars on the ALC meter, by adjusting
either the MIC control on the K3, or the output level of the
SoundBlaster card feeding it. When I reduce below the 3-bar level, it
goes to no bars in one jump. It's about right (5 bars) with line-in on
the K3 at 10, and the level on the sound card about half-way. I'm
running 3.68.

I don't have a SignaLink, but wonder if perhaps it's setup to drive a
mic level radio input?
