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 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
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?

Wish my SBRAC dish was fully operational. I'd actually be able to *track*
it--I've got 400MHz feeds, and
a WBX-based receive chain. So much coolness, so little time :-(
I tried earlier today with a handheld Arrow II yagi connected directly
to WBX. I could hear it but it was too weak to decode. A bigger yagi
should give sufficient signal.
In case you receive, it is very easy to decode the telemetry. It uses
1200 bps AFSK FM modulating the carrier, so a simple NBFM receiver and
the audio fed to e.g. multimon
(http://www.baycom.org/~tom/ham/linux/multimon.html) works. Decoded
telemetry can be submitted to the ops team at
http://beacon.engr.scu.edu/Submission.aspx
Have fun!
Alex
