I thought this might be interesting for folks to think

I won't take a lot of time on this list on this topic
(hopefully just this e-mail), but thought I'd share an
interesting strategy that is presently being employed
by the "Next Generation" of automatically-reporting
RF-based propagation-tracking systems.

If you can agree that you know as much about
propagation by *not* having any as you do when you
*do*, then it is important to know who is active, but
not being heard.

Here is a 20-meter propagation map (superimposed on a
sunlight/weather map) from the past hour, using a
system called PropNET (based on PSK31):


Compare that to 10-meters:


Here is a 20-meter propagation map from the previous
24-hours, using a different underlying map:


Compare this to 10-meters (over the past 24 hours):


Participants send Internet-streamed reports that are
gathered and displayed.  Callsign, but no vector?  No
