ESE, Earth-Sun-Earth bounce? Possible? Maybe....

ThaDood:
Ya know... If we have EME, (Earth-Moon-Earth.), bounce, could we possibly have Earth-Sun-Earth bounce? Possibly. I remember back in the 80's and 90's where ops would swear that they would hear their signal on a same FREQ that they've keyed up on 20min earlier. There was that subject with Art Bell on C2C AM over 20 years ago, where someone either called-in, or was the interviewed guest, where they talked about like a 20min delay signal coming back to them. Art then said, "That happened to me! I was on 15M, (21MHz), and about 20min later, I heard my voice key back to me from my last transmission!". Weird, but no one seemed to explore this subject after that. Now, doing the math, what's out in space that would take the time period of about 20min at the speed of light, about 10,000,000 meters per sec, to bounce an RF signal. Why not the Sun? You might argue, "That's too F'n far!", but consider just how much bigger of a reflector it could be than the Moon and Earth, or any of the planets in the known solar system. Could the Sun's atmosphere be attenuative? Maybe... But, just how reflective is the Sun's surface on various RF FREQ's? And, just where is the data that supports, or dispels, that? Passing though here... Ya think that this is a questions to pose to Dr. Tamitha Skov? She now has her amateur radio ticket.  http://www.spaceweatherwoman.com/

Yeah no it's not like the ability to record audio and play it back hasn't been around for ages now, or that anyone would ever dare to do that to bell.

secretlab:
It's an experiment that's almost certainly been done with high powered radar by now. There would be numerous applications if the sun or its magnetosphere turned out to be radio reflective. Even if that's so, the sun is an incredibly loud noise generator that would tend to drown out any reflections (just try watching your satellite dish during a solar outage). Calling Dr. Skov!

WHOA!!!! Ask, and you shall receive. THANKS!!!! Interesting, but did Stanford UNI ever follow up on that? That would be neat to do such a study with today's tech.
