Faint UNID Spanish Chatter 8272.7USB UTC June 13 0105

Heard from the Caribbean region. Very faint chatter so exact frequency is hard to tell. Seems to be in Spanish.

8195 kHz to 8815 kHz is the 8 MHz HF marine band so you likely were hearing fishing fleet communications.  8273 kHz is one of the ITU HF-SSB marine mobile 8 MHz band channels (technically a duplex channel, 8273 kHz is supposed to be paired with 8797 kHz but chances are they were just using it as a simplex channel as fishermen tend to do).  That, or they just picked a frequency and used it (as they also often tend to do!)
