It's kind of a semantic definition today. I would define it as feeding the
radio a pulse stream at the appropriate bit rate and letting the radio do all
the work. How it does the work, assuming it does it well, is really not the
point.
If the interface between your computer and radio is digital, then it's FSK. If
it's analog it's not.

Then exactly what is the true definition of FSK ?
