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?

Congrats to the DF2ZC and DH7FB on making a CW contact using the ISS as a passive reflector!
It's interesting that in the article Bernd discusses the problems with using PSK due to doppler, as well as manually having to set az and el. It seems to me that a couple of well equipped computer-controlled earth stations should be able to do this using One True Frequency principles with PSK. Wish I had the equipment to give it a try.
