Hi all,
Another status update on the Delfi-C3 satellite:
1. During the 10:40 UTC pass over the Delfi-C3 groundstation on Thursday 15th of May, the linear transponder was successfully tested and activated for a short time. The CW beacon was received well and subsequently good signals using SSB were received. An audio file of the test can be found at:
http://www.delfic3.nl/photoblog/wp-content/uploads/2008/05/pe4wj_transponder...
2. We are currently performing tests while the spacecraft is over our groundstation in order to address the downlink dropout issue. Since we take it step by step, the satellite may still experience downlink dropouts over the coming days.
3. TLE's for object G match best at this moment, we are becoming more and more confident that G is in fact Delfi-C3.
4. Up to this date, we have received over 130000 AX.25 frames from all over the world, thank you very much for your efforts and observations so far!
5. Delfi-C3 has been given an OSCAR number by AMSAT, and is now Also Known As DO-64, which stands for Delfi-C3 OSCAR 64 or Dutch OSCAR 64. It is a true honour for all team members to have Delfi-C3 join in the long tradition of OSCAR satellites.

Hi all,
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 http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&a... for details.

Congratulations!
The team and the satellite clearly deserved it.
Keep up the good work.
