Tony,
If you want to split hairs, no signal that is transmitted by RF
(or light in fiber optics) is truly "digital." Electromagnetic
signals are analog media. However, RTTY and CW certainly belong
to the family of digital modulations (on/off, mark/space, phase
reversal/no phase reversal, etc.). The coding format used is
immaterial - if the carrier can take only one of two states the
emission is considered a "digital" signal (this also applies to
each carrier in multiple carrier systems like MFSK, COFDM, etc.).
CW and RTTY are most certainly digital modes.
