I just want to say how incredible proud I am that Delfi-C3 received
its OSCAR number DO-64!
Working on the spacecraft and with the spacecraft is very rewarding.
After Wouter Jan Ubbels PE4WJ tested the transponder I also had a go
and therefore was the second person to work the transponder!
Thank you amsat-BB members for all your great posts about Delfi-C3 and
thanks for receiving telemetry and sending it in. Over 130000 frames
of data in our database is a great achievement!
** Please note that we only tested the transponder. DO-64 is still in
telemetry mode on 145.930 +/- doppler! See
