I was tuning around the band after I noted activity on 6739 kHz, so I switched up to 8992 and noticed these guys. I have logged 8989 kHz USB before, with similar sounding traffic. Spanish speakers, although this time I hear more than one station. I think they're talking about fishing, heard a couple mentions of "el barco" (the ship or the boat). QRM from another QSO on 8990 kHz (probably another group of fishing boats...)
