Hi Clive,
Good to hear you are listening for our satellite!
We have not published the telemetry format and conversion equations at this point. The reasoning behind this is that all this has been incorporated in RASCAL, so you can just read if off the screen there.
Unfortunately, tuning and getting RASCAL to lock properly turned out be harder than we thought. Therefore we have written a small manual on our website and you can find it at http://www.delfic3.nl/rascal/ under 'instructions'. The audio clip on our website is perfectly suited for this purpose and has in fact been used by ourselves and many radio-amateurs to get their set-ups up and running. Please note that this audio clip has been recorded at an exact frequency in order to get RASCAL decode and does not contain any Doppler shift.
Good luck!
Best regards,
Gerard Aalbers, Delfi-C3 team
