others require a TNC or sound card to generate the tones. FSK on

RTTY should be used in the LSB mode regardless of the band.
I don't use software for RTTY so I cant tell you a thing about that.
If the radio has RTTY as a mode, as does the TS-940 for
example, it means (1) there is an input on the back where
you put in a baseband signal and FSK comes out the antenna,
and (2) for receiving it will use a narrow filter and
center the filter up around 2.2 KHz. (By baseband I
