Have listened to the mysterious sounds at 10.512. They seem to be audible at
any hour. I have heard them at all hours of the day and night. I have no idea
what they are but the do sound interesting. There is also a similar but not the
same type of noise on 10.580. Does anyone know the origin of this noise it
almost sounds like RTTY while you quick adjust the BFO back and forth. It could
be something common. A quick google search didn't produce anything of interest.
Maybe someone out there knows.

The signal you hear on 10.580 MHz might be the so-called 'squeaky
wheel'. This signal usually exists in the lower bands (3-4 MHz) though.
What's on 10.512 MHz is called 'Backwards Music'. 'The Squeaky Wheel'
doesn't seem to be as strong a signal as 'Backwards Music' Read about
these signals at http://dspace.dial.pipex.com/brogers/page3.html.
