I was about to suggest the same.It is usual that a decayed satellite come alive again after passing sunlight (recharging).
NOAA 9 is a good examle. Most likely to hear NanoSail is on the Southern Hemisphere

Hi Alex /Marcus & All I have exactly the same result as Alexandur (not only once) I guess we used almost the same RCP antenna http://www.poes-weather.com/~patrik/AO-51/ Yesterday nite NanoSail passed FI at zenith, I could not hear anythingfrom it (once the signal jumped but staid only for < 2 sec so I'm not surewhat it was). I thought, my system is erroneous? I cross checked against ECHO(AO-51) today and it seems to work http://www.poes-weather.com/~patrik/AO-51/Jan-22-2011/ I retried on NanoSail this evning (68 deg max elev) using the new keps published on the NASA page but nothing, nada. Sumthing is fundamentally wrong how I/we do it. I guess it could be LHCP? Perhaps someone (who speak English) could query NASA on howtos? PatrikOnce they unfurled the sail, the S-band transmitter turned on, which has been draining the batteries. Transmissions have been only sporadic since then, I understand.
The radio fun might be over but there are still opportunities for visual sightings (switch to THz frequency ;-) The AL-coated solar sail is 6x larger than the reflective area of an Iridium satellite so it may produce some nice flashes under the right circumstances.
