Hi All,

Is it linear polarized, if so which?
If not, then which circular polarisation?

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

Have fun!



Yup, I knew it was 1200 AFSK FM.

Good to know you *almost* demodulated it successfully with WBX.

I rather doubt that I'll be able to get to my groups 60ft dish before
the topic becomes
uninteresting :-(

But I do have a 70cm YAGI in my store-room somewhere, perhaps I shall
dig it out, and
 wait for a pass over my city to see if I can demodulate the signal!
