6760 kHz very busy, both LSB and USB active at once. 6760 LSB has the stronger signals - noted use of "cambio" ("over") proword on 6760 kHz LSB. One of the stations has clipped audio or is slightly off-frequency...heard mention of Venezuela at 2137 UTC on 6760 LSB. Seems to be 2-3 operators having a ham radio like ragchew QSO.
