I've made exactly one contact with FT8 using a low power radio and crappy antenna. I played the generated tones from tinny computer speakers to the mic, just messing around. Someone responded! (Probably semi-automatically...) I thought it was pretty cool that it worked at all, but it doesn't seem like a very exciting mode to pass the time other than maybe to fill the log book and impress all my hypothetical friends. The resiliency might be useful for emergency communications in some way, but it would have to be a peculiar type of emergency.
