While your decode level is admirable, using the SLUSB VOX to trigger the PTT is less than reliable.
I have no experience with the Signal Link unit, but I use AFSK RTTY, JT65, JT9, ISCAT, and FSK441, making thousands of QSOs in a weekend contest. I've never used anything but VOX for any voice or digital mode, whether I was using the sound card built into my laptop or a nice USB sound card. It makes life MUCH simpler, and it works quite reliably if you set it up well.
Like with any VOX setup, you start with high VOX sensitivity while you're getting modulation levels right, then set the VOX for reliable operation. There are detailed setup instructions for audio levels (but not for setting VOX) in my review of USB sound cards at k9yc.com/publish.htm
