While I hope that someone can still answer Kirk's
question...

I thought this might be interesting for folks to think
about...
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):
http://propnet.findu.com/catch.cgi?zoom=2&geo=http://w2ev.rochesterny.org/PropNET/images/findUmaps/rectangular_1600.geo&band=hk&last=1
Compare that to 10-meters:
http://propnet.findu.com/catch.cgi?zoom=2&geo=http://w2ev.rochesterny.org/PropNET/images/findUmaps/rectangular_1600.geo&band=hy&last=1
Here is a 20-meter propagation map from the previous
24-hours, using a different underlying map:
http://propnet.findu.com/catch.cgi?geo=http://w2ev.rochesterny.org/PropNET/images/findUmaps/GeomagneticLatMap.geo&band=hk&last=24
Compare this to 10-meters (over the past 24 hours):
http://propnet.findu.com/catch.cgi?geo=http://w2ev.rochesterny.org/PropNET/images/findUmaps/GeomagneticLatMap.geo&band=hy&last=24
Participants send Internet-streamed reports that are
gathered and displayed. Callsign, but no vector? No
one reported hearing them...even though they are
active.
