Will,
I answered without reading carefully enough - most questions of that
sort are about FT8.
With RTTY through a soundcard, you should be using AFSK A mode. It
defaults to LSB and my comments about DATA A mode otherwise apply.
If you are keying the FSK pin in the ACC connector, then you can ignore
the audio levels, but you do need to convert the level to TTL voltage
levels (+5 volts and ground). If using that input, the K3 mode should
be FSK D.

Will,
Are you using DATA A mode? The normal sideband for DATA A is USB which
works with most all soundcard data modes.
If you are using USB mode instead, I suggest you change. Using Sideband
mode for data modes requires you to turn off compression and set the
equalizers flat - DATA A mode does that for you automatically, leaving
your sideband mode settings intact.
Do you have any of the audio levels set to an extreme setting? They
should all be set within mid-range. The application "power" slider, the
soundcard levels and the K3S Line level are the ones of concern.
Are you driving the K3S with sufficient audio. You should have 4 bars
solid with the 5th bar flashing on the ALC meter. See my article on that
subject at my website www.w3fpr.com for a full explanation about setting
the audio levels for soundcard Data modes.

I have a K3s (upgraded K3) and K3S (factory built).
Keying is being done with a MORTTY device. I tested with MMTTY and
N1MM+/2Tone.
The K3s is working just fine. So I understand the setup. Same
programs, same setup, but NO ONE can decode the K3S. All I see is
gibberish in the Window during TX. As far as I can tell, it is setup
identically. I have gone through the Fred Cady book.
What am I missing?? Suggestions??
