I thought of doing this back in October, when all the Sputnik-1 / early satellite discussion was happening. Echo-1, and all that. But, I would think that NASA (if not the crew) would frown on a bunch of folks on the ground hurling a few megawatts EIRP at their home in outer space. If Bob had to have a bazillion levels of safety in place for the little PCSAT-2 transmitter, I would think this would be right up there in the safety category, no?
I haven't done the math yet... Are we far enough away that 1/x**2 saves us?
