Ed,
It would seem that N1MM+ and MMTTY are fighting for the RTTY operation.
Normal RTTY operation is on lower sideband, and that is the default of
AFSK A. If it is set to upper sideband, the ALT button will switch
sidebands for you.
Make certain that you do not have "reverse" or "invert" or anything that
would change the sideband for AFSK A mode set in either MMTTY or N1MM+.

My K3 seems to be all set up for RTTY – DATA Mode, AFSK A selected, I am using
Line in on the rear panel (selected in the MENU), I use MMTTY/N1MM, and I use a
microKeyer III. All appears well except that I need to switch the K3 into USB
mode to actually transmit RTTY. If I have the K3 set to DATA mode, the PTT is
working (K3 TX light comes on) but the K3 is not transmitting tones.
This must be something simple I am overlooking. Any ideas for what to check?
