David,

the Clifton lab's Si570 kit could work with the Minima, but the automatic
filter switching, tuning, T/R, CW etc won't work. You will be better off
spending an evening hooking up the Arduino instead.

Mathematically, CW generated as single tone of SSB is no different from a
pure carrier. It is just a way to generate CW. Perfectly legal. There's no
way to differentiate a pure carrier from a single tone SSB.
