Considering that FT8 is done with 8-tone frequency-shift keying (8-FSK)
at 12000/1920 = 6.25 baud. I'd like to know how you can get that tone
in CW?
As far as the S/N threshold of the various WSJT-X modes (from the
protocol specs in the WSJT-X user guide):
FT8 : -21
JT4A : -23
JT9A : -27
JT65 : -25
QRA64A : -26
WSPR : -31
More protocol information can be found in section 17:

If you knew the code you could work that signal on CW. Quicker too.

I worked D41CV on 6 meter FT8 a couple of weeks ago. He was running
15 watts and was -18dB here. If that’s not sub-noise floor, I don’t
know what is.
