Aloha SEEDS
by Robert Smith 28 Apr '08

28 Apr '08

Aloha I copied SEEDS this evening at 44 degrees el. in Honolulu. The KEPS provided by Mineo worked very well. I used an FM HT so I had to interpret the CW via graphics. There seemed to be a lot of polarity shifts. The CW sequence was: JQ1YGU SEEDS GO CDA FFF...... repeated with varying 3 letter groups following "GO." This was my first attempt with this bird so I hope my data is reliable. 73 to all and congratulations to the Nihon University Cubesat Team!!! Domo, arigato gozaimashita! Respectfully with Aloha robert NH7WN in Honolulu

Heard Delfi-C3 at 063908 UTC
by Rick Mann 28 Apr '08

28 Apr '08

I heard Delfi-C3 on the second pass (San Francisco Bay Area), but not the first. Also, it was transmitting on 145.930 MHz (the backup frequency), not 145.870 MHz. The ICOM IC-R1500 didn't have the crackling you hear in the recording when listening on the speaker, but for some reason it got into the ADC: http://roderickmann.org/stuff/Delfi-C3.mov How very exciting! Congrats to all! -- Rick

No success with Delfi-C3
by Rick Mann 28 Apr '08

28 Apr '08

Well, I went to a hilltop at the appointed time, but try as I might, I heard nothing. Was Delfi-C3 really out of eclipse at 0455 - 0510 UTC? -- Rick

Delfi-C3 - Not Heard - - - - - Yet!!!
by Bill Ress 28 Apr '08

28 Apr '08

Congratulations on what appears to be a successful launch and satellite deployment!! Listened for Delfi-C3 from 0500 UTC to 0510 UTC here in Northern California on .870 and ,930 +/- 10 KHz and heard nothing - - - - but the satellite was in eclipse until late in my pass and then it was getting near the horizon. Just listened for Delfi-C3. Perhaps Alaska will have better luck!!! Regards...Bill - N6GHz

Congratualations for a successful launch
by Sion Chow Q. C. (9W2QC) 28 Apr '08

28 Apr '08

Dear All, Just witnessed the very successful launch of Delfi-C3 and all other satellites launched from India via DD National live. My congratulations to all those involved in making this launch a success. Now awaiting the reception of the first signals some 9 hours from now. Will have to wait for tomorrow morning to copy the first signal from Delfi-C3 due to it being in eclipse during the first pass over West Malaysia. Good luck to all those in copying the downlink. 73, Sion Chow Q. C., 9W2QC.
