Delfi-C3 1822 - 1835Z Pass - Not Heard
by Bill Ress 29 Apr '08

29 Apr '08

Signals not heard in Northern CA on this pass (on .930 or .870) which should have been much better than the least pass (less trees that way at my QTH). The next pass should be right over Delft and then to my West. Will try then. Maybe they're giving it a rest?? Regards...Bill - N6GHz

Delfi C-3 tracking an keplerian elements
by Jens Kirsten 28 Apr '08

28 Apr '08

Hi Dave, for satellite tracking I use "orbitron". It's easy to use and freeware. You can find it here: http://www.stoff.pl/ The Keplerian elements needed for tracking can be found on the Delfi C-3 web page: http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&Itemid=1… Simply copy and paste the 2-line format in a txt-file and save this file as *.txt. This txt-file can then be loaded into the satellite tracking program, for example "orbitron". Don't worry about Az/El rotor. I could receive almost every cubesat on VHF with my general groundplane antenna. Even with my HT TH-F7E reception in the field is possible. You can also download the RASCAL telemetry decoding software from the Delfi C-3 page. See here: http://www.delfic3.nl/index.php?option=com_content&task=view&id=94&Itemid=1… Best 73! from JO40ja Jens - DL2FJK D.

Delfi-C3 heard in Holland.
by Cor 28 Apr '08

28 Apr '08

Hello All, First of all congratulations to the Delfi-C3 team!!! Today I have monitored 3 passes, and the last pass was at 21:13utc - 21:26utc which gave good loud signals. I could not get the data decoded cause I made a mistake with my interface connected on my soundcard. I recorded the pass and here you can hear a short moment (which I have cut out). http://pd0rkc.ontwikkel.nl/28April2008_Delfi_1low2.mp3 73's Cor PD0RKC Ham Radio In Space: http://iss.ontwikkel.nl

Delfi-C3 heard on pass 2115UTC over TU Delft Groundstation
by Wouter Jan Ubbels 28 Apr '08

28 Apr '08

Hi all, we heard Delfi-C3 again on the 2115 pass over the groundstation and heard the spacecraft boot during the pass when she got out of eclipse. Actually, PA3WEG and I are sitting at home controlling the GS via VNC/Skype... worked fine:) Strong sigs again. We can confirm the earlier reports by G0MRF and G8ATE of the sudden dropout of the TX at 145.930. We have observed this on previous passes, usually, the TX comes up on again after a few secs but not so this time. But the "free reset" we got when getting out of the eclipse that followed got it running ok again. We are receiving quite some telemetry on our server, thanks a lot to all of you listening!!! Time to go to bed now:), more updates tomorrow. 73 Wouter Jan Ubbels PE4WJ
