K3 and DATA Mode Transmit Question

[Ed G]

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?

Ed,
     Your basic set up is correct, DATA mode - AFSK. Do use line in/out.
However, there is no need to to switch into USB. FLDIGI will take care
of everything from here. I use VOX to turn on the transmitter vice
computer control and this just works FB. And yes, K3NDM will be in NAQP
this weekend.

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+.

Did you select: MENU:MIC SEL = Line IN and set the Mic Gain
(Line In) level for four bars of ALC *AFTER* switching to AFSK A
(DATA)?

The K3/K3S Mic Gain control is overloaded (used for both mic
gain and Line In) and defaults to Mic Gain = 0 when initially
selecting data modes.
