Skipmuck and I have been hearing a very weak AM station on 6964.9 AM at various times in the evening the last few days. Often in the 2200-0200 UTC period. Always just at the threshold of audibility, and when you can hear anything, it sounds like someone talking, although too weak to even determine the language, let alone what is being said. I've yet to hear any music. Perhaps a few seconds of music around 0039, like the kind you would hear on a news program between segments. But not full songs. Last heard 0211.
There are frequent breaks in the carrier, sometimes for a few seconds, sometimes for minutes.
Most recently I heard it last night on the SDR recording. With the recent uptick in reception of pirates from Latin America, it is certainly possible it could be one of them.
Previously there were reports of the "Bird Song" pirate from Europe on 6965, which this certainly is not.
The frequent breaks in the transmission (not fade outs, but sharp breaks as though the transmitter was turned off then back on) make me wonder if it is some sort of spur or other artifact.
