Re: ATV from Space?



Why not start out with a simpler FSTV downlink of real-time video of  
the Earth?

It might get boring after a while, but it would be a good opportunity  
to learn about link characteristics, etc for FSTV in space...

Cloud cover and geography could be viewed, and maybe ham information  
could be broadcast in-band via Closed Caption! ;-)
