Paul,
Thanks for the update. Without the sail deployed the 10cm x 10cm x 10cm satellite's luminance is still very low. It should be much more interesting when the 170 sq ft sail is deployed. This sail is still smaller than the ISS solar panels.
I will be in up state New Hampshire during the first week of August. I hope the sail is deployed and I see a light show.
When I return to my FN20 QTH, I hope to try meteor scatter techniques to make a QSO off the sail. I'm sure many others will try as well. Scatter QSOs off the ISS are rare.

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?

Now for a surface to be reflective, how big does it need to be in terms of wvelength?
That's textbook radar theory - see: http://slideplayer.com/slide/3927976/13/images/9/Modelling+d evelopment+&+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?
