by Peer-Axel Kroeske, DL2LBP Radio Rebelde from Cuba and WDHP from the Virgin Inslands can be heard regularly with audio here. The weak wide carriers from 16-21 UTC could possibly be Australia. The Brisbane Perseus receiver picks up carriers on these. The strong ones are probably pirates, QSOing (dotted) and broadcasting (05-07 UTC). The scale shows frequencies +0.5 Hz. If you move the mouse over the graphic the labels will show the right value. The clusters of 10W service stations from the USA do not seem to get through.
