Some data mode applications will do RTTY in USB by inverting the
mark/space. If using one of those, stay in DATA A submode for RTTY.
But do follow the instructions in the documentation for the software you
are using. Most DATA modes (other than RTTY) will operate from a
waterfall display where you click on a signal of interest and that
signal is decoded. The bandwidth controls on the receiver would
normally be set wide to see a wide waterfall with many signals.
Most using RTTY prefer MMTTY which would normally be used with AFSK A
sub-mode on the K3/K3S (LSB on other transceivers). You would normally
tune to the RTTY signal with the VFO knob, and operate with a narrow
bandwidth.

This is grossly oversimplified, but it's a place to start: the software
makes noises, the transmitter transmits them, the remote receiver
receives them, and the software at the other end turns them back into
letters on the screen.
Different noises for RTTY, PSK-31, Olivia, Throb, Hellescriber, etc. but
the technique does not change, and once you get a program working, you
likely don't need to change anything but the VFO to change modes.
I'd start with PSK-31 because it's popular. DATA A will do fine.

I'm also interested.
Are you saying that the K3 should be set to DATA A and the controlling
software on the PC will handle TX/RX, whether it's PSK, RTTY etc.?
