Re: 144 Mhz contact made using ISS as passive reflector




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?
