That's not my understanding of the manuals description of the pinouts.

FSK works fine with N1MM but AFSK doesn't. So, it's not a software issue since 
AFSK doesn't work with fldigi, either.

And yes, the rig is being keyed on pin 13 and not by CAT. When I used FSK I 
keyed the rig with ACC2-9. As I previously stated, AFSK does not work when 
using ACC2-9, also, and my understanding from the manuals description of the 
pinouts I'm suppose to use ACC2-13 anyway. Either I have a rig config problem 
or I have a bad ACC2 jack or something internally wrong with the rig.

BTW, I'm testing on 20 meters and USB and using my Icom 706 to monitor what's 
being transmitted by the TS2000 into a dummy load.
