[Elecraft] K3 and DATA Mode Transmit Question

[Don Wilhelm]

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+.

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.
