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
at the moment(?)

Hi Alex /Marcus & All

I have exactly the same result as Alexandur (not only once)
I guess we used almost the same RCP antenna

Yesterday nite NanoSail passed FI at zenith, I could not hear anything
from it (once the signal jumped but staid only for < 2 sec so I'm not sure
what it was).
I thought, my system is erroneous? I cross checked against ECHO(AO-51)
today and it seems to work

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?

Once 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.
