[Elecraft] KX2 RTTY Help

Trying to get RTTY running on my KX2, but no luck, so far.

The KX2 is setup for WSJTx and works properly (TX and RX) with both 
straight audio cables to the computer and through a SignaLink USB. My 
conclusion from this is that the audio connections and audio gains must 
be set relatively close.

Receive problems:
I have both MMTTY & 2Tone (via N1MM) setup. In MMTTY, I see no receive 
trace on the spectrum scope, just a dot in the middle of the XY scope. 
In 2Tone, I have the familiar two humps, but they are in left sector of 
the display. Audio gain controls do not seem to effect the display, and 
I cannot find why the display is displaced.

Transmit problem:
Both MMTTY and 2Tone transmit; however I just get the carrier, not the 
Mark and Shift. This occurs with both the SignaLink and direct audio 
cables from the computer to the KX2. They both TX, so PTT is working.

I have tried the above in both DATA A and AFSK A modes.

Must be making silly mistake(s).  Help!

Thanks.
