C3 heard at KM17VX at 1-5-2008 18:55 utc and it was transmitting tlm
at 145.930MHz. Transmission started as soon as the spacecraft went out
of eclipse. Tlm captured and uploaded to the server.

Hi,
Today tracked 7 passes of delfic3 all with good signals. The transmitter on
145.930 is random on
and off each pass but its always present. Tracking NORAD# 32787 matches AOS
and LOS very well.
Interesting was pass 4 and 5 with low elevation. Signals where good and I
could decode some
packets on pass 4. Received signals on pass 5 but decoded nothing because the
tx switched on to
late (just before LOS).
I noticed in RASCAL a correlation between the distortion on the downlink
system and the OBC System
bus voltage value. When the voltage showed 7~8 volts the distortion was
present. It looks like the
distortion intervals has also a correlation to the satellite spin cycle.

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.jpg
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.

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_pa3guo_
cw_437.275_01_deg.mp3
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.

I have a steady tone at 145.930 USB; approximately 1500-1900Hz. Orbitron
shows Delfi should be coming over soon. Is steady tone normal?

Hi Domenico,
Yes a long time since we made those contacts. I still have all the 24 GHz
receive equipment. The system has been upgraded with a 2 foot dish with
circular feed and 1.3 dB nf preamp.
I also have 47 GHz equipment ready.
I can't wait for P3E.

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.

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.

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:

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.

Dear All,
Has anyone successfully copied CW telemetry from AAUSAT-II on 437.425 MHz
and CANX-2 on 437.478 MHz? If so, could someone kindly point out what keps
are they using for this 2 satellites? Right now, all my time is dedicated
to Cute-1.7 + APDII, Seeds, Compass-1 and Delfi-C3. But I think I should
not leave out both of them. Quick checks during Object J and E passes for
AAUSAT-II and CANX-2 but I did not hear anything. Maybe I will pay more
attention to them later.
Also, I read somewhere that CANX-2 also transmits on 2407.650 MHz. Can
someone confirm that this is operational too?

Mike,
This one was copied this morning. About 2 minutes long and some Doppler
tuning will be heard. Cut and crop or do anything you wish with it. Hope
this will help you. Good luck in your satellite presentation.

The 0400Z pass was all OK even if it was a low one 20 packet decoded and DELFI
was in full illumination since 0342Z a good 15 minutes
before the pass and everything seems normal. I guess the problems appears just
went the satellite is emerging from eclipse and that the
power is just starting to flow in.
I will try to recheck in the evening pass if i got the same results as
yesterday evening.
At the end of the pass another carrier with doppler appear i try to check who
was the culprit but VO-52 who is on a similar orbit was on
the other side of the earth. I run a simulation on all the other active
satellite around 0400Z to see which one will be the best candidate
but none of them was in range!!! Another phantom of the opera signal? I just
hope one of the other 8 cubes does not also share the same
downlink frequency!
