C3 packets

Anyone have any short audio files of C3 they would care to share that I could use for an upcoming satellite presentation? I haven't had the time yet to catch and record any myself. 73, Mike N1JEZ AMSAT #29649 "A closed mouth gathers no feet"

Delfi-C3 and Seeds over West Malaysia
by Sion Chow Q. C. (9W2QC) 01 May '08

01 May '08

Dear All, Below is a pass of Delfi-C3 and Seeds over West Malaysia. Time was 0958 Local or 0158 UTC, Maximum Elevation 21 degrees. Seeds was heard at first and then I moved to Delfi-C3 on 145.930 MHz. Good to hear Delfi-C3 transmitting again over West Malaysia. Below are some data: Brief Seeds CW before I moved to Delfi-C3: http://www.9w2qc.net/amsatbb/seeds02may0958.mp3 There were some audio problems towards the end of the file. This is due to my PC and has nothing to do with the satellite. Throughout the transmission, CW sounded nicely via the IC-910H's internal speaker. Screenshot of RASCAL receiving Delfi-C3: http://www.9w2qc.net/amsatbb/delfi02may0958.JPG Some 170+ packers from Delfi-C3 as decoded by RASCAL: http://www.9w2qc.net/amsatbb/delfi02may0958.txt Seeds was tracked using Object J and Delfi-C3 using Object E. 73, Sion Chow Q. C., 9W2QC.

Hello All, Pass at 0035 UTC. SEEDS was transmitting packets in 1200 baud AFSK packet - didn't have the TNC hooked up so I didn't get anything. Heard CUTE and COMPASS but not Delfi-C3. 73 de David VK5DG

Steady Tone 145.930 USB
by D. Mynatt 01 May '08

01 May '08

I have a steady tone at 145.930 USB; approximately 1500-1900Hz. Orbitron shows Delfi should be coming over soon. Is steady tone normal? Dave ===== http://sciencecenter.no-ip.org SID ID: S-0258 APRS IGate KA0SWT LAT: 38'16.278" N LON: -104'40.537" W Alt: 4780ft DM78

Cute-1.7 very low elevation pass very good !
by Henk, PA3GUO 01 May '08

01 May '08

Today, May 1st, tirst opportunity in the evening was an only 1.0 (!) degrees elevation pass. Using the latest kepler sets, HamRadioDeluxe (automatic doppler correction) and the TS2000X, my 2x8 elements beam (no pre-amp) picked up the signal beautifully, all the way from AOS to LOS ! Sound bite: http://home.vianetworks.nl/users/hamoen/pa3guo/cute_17_01may08_1725utc_pa3g… Again: less then one degree elevation, no pre-amp, from a 100mW transmitter in space. Fantastic satellite ! Henk, PA3GUO ps: the 75 degrees pass later the evening, showed the kepler set was good also: I used a 500Hz CW filter, and HRD automatically tuned perfectly for doppler.

DELFI-C3 rx report 2008-05-01 (PA3GUO)
by Henk, PA3GUO 01 May '08

01 May '08

Hi Rob, Those are indeed very interesting results ! Here are is another analysis I did on the spin rate, today during a 17 degrees maximum elevation pass (19:00utc). Measurement started just before the max 17 degrees elevation moment. At the end of the pass the TX went off, then on, and then stayed off (see the white arrows in the picture). I extrapolated the envelope of the signal. With the latest kepler sets auto doppler correction worked perfect. The graph: http://home.vianetworks.nl/users/hamoen/pa3guo/dc3_01may08_pa3guo_rotation.… Results: There seem to be two different periods: - one of 1:04 seconds - inside those: one period of 30 secs, followed by a period of 34 secs.
