6984 USB via Indiana remote SDR [KiwiSDR]. Checked several other remote SDRs (and local RX) and can only hear these guys on the Indiana SDR.
Tuned in at 1040 UTC and QSO was already in-progress.
6984 kHz USB - Spanish langauge, right above noise floor but readable - sounds like freebanders. Faded away or went QRT at 1045 UTC.
