Some mode on 40 meters noise wide band
 

Hi Folks;
I'm hearing a super-wide noise, sorta sounds like MT63 but it's
almost 10kc wide! I'd say it's 3.999mHz LSB that extends to 3.991.
It's not letting up! It's steady and strong. A little multipath
distortion, but Screamin' in Jersey.

I don't know what MT63 sounds like, but you might be hearing DRM on
3995 from Radio Deutsche Welle.

Hi!
Thanks for the reply! I think you're right! I found the same
stuff under 9.8mHz. I found a site http://www.drm.org/ that talks
much about it. It's amazing how they can squeeze this much data into
only 10kc of bandwidth with enough reliability to work on HF! I can
see all radios, even AM broadcst band going to this. I would pretty
much obsolete a lot of current equipment..
