During the pass of 09:30 UTC over Europe, we have performed successful\ndatabase dumps again, some of you may have heard these since the frames\nsound quite different compared to normal housekeeping / payload frames.\nThese frames are also captured by RASCAL, displayed in the terminal and\nuploaded to our server\n\n2. During this same pass, we have successfully switched the spacecraft to\nits primary radio on 145.870MHz temporarily, after this switch, the\nsatellite came back on on the 145.930MHz downlink. Telemetry indicated that\nthe primary radio on 145.870MHz is healthy and working fine so that is good\nnews.\nNote that the satellite will normally transmit on 145.930MHz for the time\nbeing, unless we command her to go to 145.870MHz. This might occur more in\nthe coming days when the s/c is in range of our groundstation, so listeners\nin Europe might want to check the 145.870MHz transmitter also when the\n145.930MHz transmitter shuts down. We have noted that the 145.870MHz\ntransmitter is a little (1kHz) low in frequency so actually on 145.869MHz.\n\n3. Yesterday (April 30) we were able to successfully command on our backup\ncommand uplink so we have both command uplinks working nominally at this\nmoment.\n\n4. We are currently investigating the rotational behaviour of the satellite,\nyour observations w.r.t. spin rate / signal strength are more than welcome,\ncombined with telemetry we should be able to fully assess how the s/c is\nrotating. We suspect that this may actually give a clue to the TX dropouts\nexperienced.\n\n5. We have successfully gathered raw data from the wireless sun sensor\npayload\n\n6. Note that we have locked the bootcounter value so it will always display\n2273 from now on until we unlock it again\n\n7. Although TLE's for object #32787 are listed on our webpage, we are not\nentirely sure that this is in fact Delfi-C3. We probably won't have\nconfirmation until after a day or 3-4 when the satellites have separated a\nbit more. For now, object #32787 should be fine for tracking though, but\nyour observations w.r.t. AOS / LOS times are welcome\n\n8. Following the report from VE2DWE about the TX sounding distorted, we\nwould like to ask everyone to record a wav if possible when this phenomenom\nis heard, you can send the wav files to [email protected] . Our\ninbox has no problem with large file sizes.\n\n\n73 on behalf of the Delfi-C3 team\n\nWouter Jan Ubbels PE4WJ\n", "attachments": [] }
