I will be making a trip to Las Vegas to see some vendors in a couple of
weeks and am thinking about taking an ultra-lite station with me to work
the FM birds the first day while I am out there. The best day I can
hope to work the birds will be 4/28. Satscape indicates the following
passes will be available -
SO-50 [+] 28 APR 2008 09:42:48 337 26 (AZ 046)
AO-51 [+] 28 APR 2008 09:49:28 001 30 (AZ 293)
SO-50 [+] 28 APR 2008 11:23:29 322 43 (AZ 249)
AO-27 [+] 28 APR 2008 15:21:09 155 59 (AZ 073)
AO-27 [+] 28 APR 2008 17:02:11 210 15 (AZ 269)
AO-51 [+] 28 APR 2008 19:22:53 143 36 (AZ 066)
AO-51 [+] 28 APR 2008 21:02:02 197 25 (AZ 269)
The times listed are in CDT, I didnt get the conversion made for PDT
when I ran these calculations. I am planning on taking 2 handhelds -
one for uplink and one for downlink so I can run full duplex. Planning
on using 1/4 wave 2 mtr mag mount and 5/8 wave 70cm mag mount for
antennas. I used DM25 as a beginning reference for the pass calcs.
Will be within 2 to 3 hours of Las Vegas and North during most of the
passes.
I havent flown with ham gear since before 9/11. Anything I need to know
to be prepared to deal with TSA ? I plan on putting the mag antennas in
the check-in luggage and will put the handhelds in a Pelican case that
will have some recording gear I will be using to record some interviews
for a radio show that I do. No promises that I will get to appear on
any or all of the passes but I will do my best.
Thanks,
Ron

Hello Steve, K4HG,
There is 'findu_com web' for ISS APRS packet:
http://www.ariss.net/index.cgi?absolute=1
And there is 'findu_com web' for PCSAT-1 APRS packet:
http://www.findu.com/cgi-bin/pcsat.cgi?absolute=1
We want to open similarly 'findu_com web' for L/U digital mode
of AO-51 APRS packet like ISS and PCSAT-1.
Thank you.

For those who can't get enough information about this excellent
project, or those who just like high-res pictures of the construction
of satellites, there is a ppt slideshow at
http://www.delfic3.nl/forum/showthread.php?t=873
Until I saw the last slide, I didn't know what satellites were truly built of.
That slideshow shows the telemetry capture software in operation
(named 'RASCAL'?). Is there anywhere we can download this? It seems to
be based in the Warbler demodulator, so we could use that to check out
our computers and soundcards, I suppose.
Less than two weeks to go, with any luck
73, Bruce

Hi Bruce,
yes, that's a very recent presentation we gave for local Dutch hams, enjoy!
Indeed, the software is named RASCAL, and yes, the demod algorithm of
Warbler is in there so you can indeed check whether your setup is ok by
using Warbler. The rest of RASCAL (GUI, connection to server etc. etc.) was
specially developed by the team.
The screenshot is actually of the beta test we ran 3 weeks ago, with a
handful of radio amateurs. The software passed this test with flying
colours, only some minor cosmetic changes will be made. We will publish the
software on our website when we are back from our pre-launch checkout trip
from India, which will be in the week of april 14th. So stay tuned:)
greetings from warm India,
Wouter Jan Ubbels VU/PE4WJ

I have an old 416 TB, need wiring help.? It currently has been wired for use
with? the PS-4 switching box,,, instructions say that as wired, it will be LHC
when not energized,,,? RHC only when energized.
I want the opposite,,, RHC when NOT energized.??? (I am not going to
energize?? --? not going to use? the PS-4)
How do I wire it to be RHC when NOT energized...
?I do not have the original wiring harness for use without the PS-4.
or should I just go down to HRO and buy a linear? 432 antenna?? I need RHC or
linear, i dont care which.

Hi Bruce (and the rest of bb),
The presentation which is on the Delfi-C3 forum is one of Wouter (for
now VU/PE4WJ) I updated for a presentation in dutch.
If there is interest (and my guess is there is) I will switch some of
the dutch slides back with English ones and I'll post that one also
for your viewing pleasure ;).
Maybe tonight if I can find time to do that.

There is a group that is willing to give we amateurs a LEO satellite
with mode-B linear transponder on board and at no cost to us! The only
catch is that they hope we will give them our help in collecting
telemetry from their experiment for the first three months of the
bird's life. Does this sound too good to be true? Well, in fact, not
only is it true, but the satellite is due to launch in only two weeks!
For those who haven't been following the story of the Delfi-C3
satellite, that's exactly the deal that these researchers from Holland
are offering us. It's the sweetest opportunity in a long time, and
we'd be wise to respond with an overwhelming response. If we do, we'll
make it clear to the myriad cubesat developers that, by leaving some
communications hardware for us to work with after their experiments
end, they can be sure of our full support in collecting telemetry.
Delfi-C3 matters greatly to us for two other reasons. First, it is the
first time that amateur voice communications equipment has flown in
the inexpensive 'cubesat' form-factor. If Delfi shows how this can be
done, we can expect other groups to follow in their path. Delfi-C3 is
sized 30x10cm, a stack three times the size of the usual cubesat.
Maybe the software-defined transponder concept could miniturize our
hardware to the point that we could get a ham transponder into an even
cheaper 20x10 cubesat, making it even more affordable for local groups
to undertake. Secondly, Delfi-C3's experiment pertains to solar panel
technology, something we should all hope progresses to give us more
watts in space.
If you've been lukewarm on cubesats because you think they're not
'real satellites' or if you're in the doldrums because the satellite
industry seems to be keeping us from afordable launches, here's your
chance to fix things, at least on the LEO side:
1. Ensure your 2m downlink station is working well. You'll probably
need a yagi to collect telemetry. Get that low noise preamp installed
on the mast.
2. Ensure that your radio/souncard interface is working well. Test
this with some software APRS packet decoding, for example.
3. Get a software 1200 bpsk demodulator. The java program from the
lead developer of Delfi-C3 will probably work:
http://home.casema.nl/b.ubbels/Warbler.htm
then test it with the audio files available there. You might need to
fiddle with the 'stereo mixer' settings in your Win32 machine to get
the WAV file to play back into the computer. You'll want to download
the RASCAL software from the delfi-c3 people when it is available.
4. Join the cubesat chat rooms during and after the launch to help
these projects identify their birds and apply the right TLEs. This is
high drama, and its great fun to see just how good at this stuff
people like Mineo and Mike are.
5. Collect telemetry! And help out the other cube projects, too, while
you're at it.
Some of you with really great HEO-class stations can use them to great
effect here.
73, Bruce
