I'm getting something here with signal just above the noise at 2340 UTC. OMCS? Sounds like some strange music and extraterrestrial sounds. Tough propagation with all these solar flares over the last few days. Possible man talking at 2351 UTC but not sure...could be pesky splash.
I think they signed off sometime around 2350 UTC and after that was pesky bleeding over from 6933 LSB as JFarley posted.
