Hi Domenico,

Delfi-C3 has been in amateur transponder mode from the end of July 2008 till
mid-October 2008, after which we sadly have had to conclude that the
transponder had failed. We do not know the exact failure cause, but it is a
failure in the receive section of the transponder. Sad but true, it is the
only component to have failed on the satellite so far... :( everything else
is running ok apart from some minor quirks like regular downlink drop outs
which are related to the databus and are not critical. I have only been able
to make a handful QSO's on the transponder myself, would have loved to make
many more!
After this sad conclusion, we have decided to switch the satellite back to
science mode, a mode in which it transmits payload data on 145.870 1200Bd
AX.25 BPSK to at least give it a useful life which will hopefully last for
many more years to come!

73,

Wouter Jan Ubbels PE4WJ
