After checking several remote SDRs (due to an extremely strong local carrier parked right on 6764 kHz making copy impossible no matter what the bandpass settings are) I found one where I can sort of tune the signals on 6762 kHz. Tried 6762.2 kHz USB and its still distorted. I'm beginning to think this has more to do with the language being spoken vs. the frequency and mode. That, or there's two QSOs going on, one in LSB and the other in USB and that's why I can't seem to tune it in completely.
At 0032 UTC, I heard a clear transmission on 6762 kHz USB, in broken English (very thick Caribbean-sounding accent) "yeah okay" and "yeah batty boy". Possibly coming from Jamaica??
