MMTTY [free] will provide stand-alone AFSK RTTY with your current setup.
N1MM will also use the MMTTY engine for you in a contest or when
calling DX in a pileup. Download MMTTY to someplace on your computer,
and then in the N1MM setup, tell it where to find MMTTY. Then, in N1MM
when you open the digital interface window, the MMTTY window will also
come up. MMTTY is a tad complex and obscure, but the good news is that
it works well right out of the box, so you can ignore most of the options.
Never understood the infatuation with direct FSK, but to each his own.
For RTTY, select AFSK-A. You can select audio frequency with the K3
PITCH control, there are 4 choices I believe, mine is at 915 Hz
[lowest]. Be sure MMTTY is also set at 915. Recent firmware editions
include a filter in AFSK-A which really narrows your signal. AFSK-A is LSB.
Put the K3 in TX TEST, go to transmit, and adjust the MIC GAIN for 4
solid bars ALC with the 5th flickering. Then go to TX NORM and set the
desired power. You can't control the power on a K3 with the MIC GAIN.
You won't find many casual QSO's on RTTY. "AFSK PSK31" is actually
redundant. :-)

I think I actually misworded things.
I have N1MM and use it for CW all the time.
I have the audio cables, and everything works fine for AFSK PSK31.
I just have little experience recently with RTTY, and I just want to
set it up correctly.

Apparently I haven't fooled with RTTY of any seriousness in years,
but I am starting to get interested in DX chasing with it.
So, how do you guys recommend setting up the K3. I see FSK is much
preferred by most to AFSK using say FLDIGI and audio input now
days.
I know VERY little about this. I am a CW DX'er, but just interested
in learning this and possibly doing a contest sometime.
Thanks,
