it started off at 1900z with a carrier for a few seconds then an OM yelling "anybody out there ? can anyone hear me ? no one is listening"
since then, ive been hearing interesting outtakes/demos from the beatles.
the transmitter in use has the same signature as others OP's i have seen posted, most of the audio is on the LSB side of AM, frequency shifts a bit with modulation, seems to be slightly FM, wide audio band pass (no brick wall filter).
id take a wild guess its a "LuLu" transmitter being used.
2005z - "its the nutty professor!" with unintelligible talking "thanks for listening bye!" - off at 2007z
thanks for the outtakes/demos from the beatles, it was different and enjoyable
