Kurt,

I have been doing this for a while now, here is an example:

https://www.nk7z.net/rfi-site-survey-part-ii-interpretation/

Go down about 3/4 of the way down, and you will see a videop player, it 
is the only one on that page.  Hit play...

The original file is far more detailed than the player I'm using will 
allow...

You will see a movie of the HDSDR waterfall, running across a 24 hour 
period, and covering the entire 40 meter band.

You can see all the CW stations start the CQ WW CW contest at 5 PM... 
If you use chromecast the cast will send the full resolution file to the 
TV, which on a 50 inch device looks pretty impressive...

If anyone wants the full file let me know and I'll stick it on dropbox.

73, and thanks,
Dave (NK7Z)
