I noticed with only four panadapters open, each about 100-150 kHz wide, the noise floor is between 100-90 dB.  If I set the preamp to 20dB of course it lowers accordingly.  Before the update my noise floor was around 120 dB without the preamp.  I just tried this with just one panadapter open even at only 20 kHz showing and the noise floor is still about 90 dB.  

What happened?

    Doing ANOTHER database reset brought it back to normal.  Getting old doing all these resets. :)

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu.
