Interesting, How all the articles say it is supposed to be this super bright thing. brighter than anything other than the moon or sun. like -10 mag. Yet I just checked Heavens above to see if they have it and they do, but they are saying all the passes are near 0 mag + or - a mag, sooo HUH?

That's textbook radar theory - see: http://slideplayer.com/slide/3927976/13/images/9/Modelling+development+&+res <http://slideplayer.com/slide/3927976/13/images/9/Modelling+development+&+res> ults.jpg Provided that you have enough EIRP (EME rig?), I would expect that 6m or 2m would probably be a good choice of band, since shorter wavelengths are more likely to undergo optical scattering, which might not be in the direction of your intended RX. On this subject, have any hams tried using the ISS as a passive RF reflector? 73 ZL2WRW Ross Whenmouth _______________________________________________ Sent via AMSAT-BB@amsat.org <mailto:AMSAT-BB@amsat.org>.
