[Elecraft] FLDIGI with K3s

I recommend reading the FLDIGI manual.  It states that USB is used for digital modes, including RTTY.  The K3 uses USB for Data A and LSB for Data AFSK. 
In my first contest I was having problems getting reliable decoding and not many responses to my calls. I asked a friend who is an PVRC RTTY expert for help. He monitored my transmission and determined my signal was reversed. He said some operators would see that and change mode to answer me. Enabling Rv (reverse) on the lower FLDIGI control panel solved problem. However my logging software sends a mode command to radio when I select a spot and change frequency and it turns off Rv. A better solution is Data A mode which uses USB. 
There may be a way to change the FLDIGI RTTY  default however I have not found it in the menus. Has anyone found it?
