Isn't hand sent Morse Code a jittery PAM / PWM combo? A computer can generate a less jittery code.
But machine reception is something else. PAM is the simplest, but the worst to decode reliably digital modulation in the presence of noise and interference, which are the rule at least on HF. 73, Jose, CO2JA --- J.
