I may have missed this in the recent posts but what is the name I would look for if downloading keps and data for this site. I updated my Nova and would like to see this on my map. Fred VE3FAL

Hello All, I received DelfiC3 19:57UTC (orbit nr. 25). I think I received DelfiC3 a bit earlier than my trackings software predicted. Signals where good when DelfiC3 was at south, at north signals dissapeared. Here is a photo/screenshot of Rascal: http://pd0rkc.ontwikkel.nl/29April2008DelfiC3_TLE_orbit25_B.jpg Below you see raw telemetry data. Received with Yaesu FT-897 7el. M2 yagi with horizontal polarisation. I only controlled azimuth because I have no elevation rotor yet. 73's Cor PD0RKC Ham Radio In Space: http://pd0rkc.ontwikkel.nl from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 5f

DelfiC3 heard 29-April 18:23UTC - 18:29UTC.
by Cor 29 Apr '08

29 Apr '08

Hello All, There was a low elevation pass in range of Holland (29-April-2008). I could hear the BPSK signal direct at AOS. Signals was somethimes a bid weak (which is normal) and somethimes strong. At 18:29UTC signal stopped direct, maybe mission control team knows why. I could not get data visible on RASCAL because it refuce to accept the audio, the RASCAL audio level meter does not respond. I did select my AC93 soundcard in RASCAL but it does not work. When DelfiC3 was LOS, I have checked PSK signals on HF which decoded fine. Who has some tips? 73's Cor PD0RKC Ham Radio In Space: http://iss.ontwikkel.nl

Re: ao27.org possible schedule error?
by Henk, PA3GUO 29 Apr '08

29 Apr '08

Hi ! Same observation here this weekend. The satellite is a few minutes ahead of the website (it changes mode earlier as the website indicates) Henk, PA3GUO ------------------------------------------------ Hi Sam! > From what I see, the schedule on ao27.org seems to be 8-10 mins off > from actual time. The bird doesn't seem to have changed schedule at all. Can anyone else confirm this? Your observation appears to be correct. I have seen this about a month or so after the satellite gets a new schedule uploaded to it. It appears to be a glitch on the web site. AO-27 should be turning on during afternoon passes when it crosses approximately 29 degrees North latitude.

Dear All, Finally managed to copy some signals from SEEDS this evening (29th April 2008) after missing it this morning. Some CW telemetry decoded by myself are as follows: Time:2248 Hours Local/1448 Hours UTC Max Elevation: 57 degree 064030 ... JQ1YUSEEDSG4001166B7D69FFE008009000008008007A3E945A3BA0010 ... D064030 ... JQ1YUSEEDSG400116AD2D1BFFE ... 58A4FAAD1100000001000100010A8E0 Time: 2115 Hours Local/1315 Hours UTC Max Elevation: 3 degree 2343BD64FFE007009007007008008A02A059F9A511100000001000100010AC3064030 i ... 8007007008A18A1AA0EA67110000000...........00100010AC4064030 ... JQ1YGUSEE...........4001244DAD61FFE008009000000009008A55A58A5EAAD11000000010 001.....064030 JQ1YGUSEEDSG4001248E8D68FFEO.....00900800800796AA6B9629C31100000001000...... ..... Also tried to listen to the other satellites during the first pass but did not manage to hear anything else. Listened briefly for Cute-1.7+APDII on the second pass but did not hear anything. Concentrated on SEEDS as it was very loud and also I was operating from out of the shack via VNC/Teamspeak and did not want to mess things up. For both passes, object C keps were used. Signals were strong with occasional QSB. Equipment used was IC-910H, 2x15 Element vertically polarized yagi with SP-7000 preamp. Due to my poor CW copying skills, I will post a recording of both passes shortly in case I copied some letters wrongly. 73, Sion Chow Q. C., 9W2QC.

Delfi-C3 HEARD over the Delfi-C3 groundstation 08:53 UTC pass - s/c in EMERGENCY mode
by Wouter Jan Ubbels 29 Apr '08

29 Apr '08

Hi all, we just heard Delfi-C3 again over the Delfi-C3 groundstation on the 08:53 pass. Signal was strong, NORAD Object #32786 seemed to fit best, but we are not 100% sure. Judging from the downlink, the spacecraft is in emergency mode. TLE's for object #32786: 1 32786U 08021D 08119.87805543 .00000721 00000-0 10000-3 0 115 2 32786 097.9993 179.9103 0012861 292.3044 067.6803 14.80984919 100 Frequency: 145.930MHz Downlink signal in emergency mode are 2 tones, of 500Hz and 900Hz each, modulated DSB onto the (suppressed) carrier, use USB to receive this signal. These tones themselves are modulated with 100Bd FSK each with raw payload data. If you hear this signal, please record a wav file if possible. If you hear Delfi-C3 please send your reports to missioncontrol(a)delfic3.nl stating AOS, LOS, frequency, signal strength If possible, please record and attach a WAV file Thanks!

Delfi-C3 HEARD again in SCIENCE mode over the Delfi-C3 groundstation 10:30 UTC
by Wouter Jan Ubbels 29 Apr '08

29 Apr '08

All, Delfi-C3 was heard again with solid signals in SCIENCE mode on 145.930MHz BPSK :) over the TU Delft Groundstation. Everything looked nominal again. We seem to have had an issue with our databus, but the next eclipse solved it. Furthermore, we verified the command uplink functionality and were able to talk to the satellite, we even got an on-board database dump upon command. Awesome. pfewwww.... interesting days these indeed Thanks all for listening and submitting telemetry!!! Wouter Jan Ubbels PE4WJ
