Hello all,
As a part of a student satellite project from India, I have a few questions
regarding how can i improve my reception of data on the ground station. We
have a TS2000 and have designed a few yagi antennas for uhf and vhf band. I
would like to know some satellites on which we can practice receiving any
signal. We are totally new to this system and have practiced some failed
attempts of the same. Further, we would really appreciate If anyone could
help on how we can increase our reception power. Any other help or advice
would also be appreciated. Thank you.
Aayush Yadav,
Team Pratham,
IIT Bombay.

Dear Aayush,
There are plenty of amateur satellites you can try to receive. Head over
to http://www.amsat.org/status/ for the list of the "most popular" ones,
together with status reports. Also, there's a huge list in
http://www.dk3wn.info/p/?page_id=29535
I would mention a few of the strongest ones, but if you're using
circularly polarized yagis on a rotator (as you should be using on a
serious groundstation), you should be able to receive any satellite indeed.

Dani M0HXM/EA4GPZ.

An International Space Station school contact has been planned with
participants at Dragonskolan, Ume?, Sweden on 25 Nov. The event is scheduled
to begin at approximately 09:44 UTC. It is recommended that you start
listening approximately 10 minutes before this time.The duration of the
contact is approximately 9 minutes and 30 seconds. The contact will be a
telebridge between NA1SS and VE4ISS. The contact should be audible over
portions of Canada and adjacent areas. Interested parties are invited to
listen in on the 145.80 MHz downlink. The contact is expected to be
conducted in English.
Dragonskolan is one of the biggest upper secondary schools in Sweden and is
located in central Ume?. Currently hosting 1820 students aged 16-19 and 300
staff; it has recently been renovated to meet modern needs in a stimulating
learning environment.
At Dragonskolan, we have an ethos where we believe we can offer our students
three meaningful and enjoyable years. Our core values are "open and bright",
referring not only to the physical surroundings but also to the social
climate.
Dragonskolan is the biggest meeting place for young people in Ume?,
A wide range of 3 year programs, college preparatory and vocational, are
offered here, ranging from natural science to humanities and technological
science.
At the core of the school is the Dragonskolan Technology Center where
everything is taught from industrial welding technology to electronics,
automation, computer science, CAD and much more.
With its close ties to the industry, the school keeps in pace with the
latest industrial technology ensuring the students get the best education
available within their chosen field.
Participants will ask as many of the following questions as time allows:
1. How would you describe the smell in space?
2. Is going to space what you expected it to be?
3. How dark is it dark in space?
4. Have you ever fantasized about seeing an alien life form?
5. Do you have access to internet and social media on the space station?
6. What is the first thing you want to do when you get back home?
7. What is the annual salary as an astronaut?
8. When are humans expected to go to Mars?
9. How does one feel in size aboard the space station?
10. If a person is in the middle of a room in aboard the space station
without reaching the walls. How would that person move from that
position without throwing something in the opposite direction?
11. Where does the oxygen come from?
12. How has your vision of life changed from being in space?
13. Which time is correct in space?
14. How do you take a shower in low gravity?
15. Do you ever get tired of each other on the space station?
16. Don't you miss your family and friends?
17. Do you think people get another view on our problems on earth after a
trip to space?
18. What does it feel like to sleep in space?
19. Was it worth all the training to go to space?
20. What is the best experience you have had so far going to space?

Next planned event(s):
ARISS is an international educational outreach program partnering the
volunteer support and leadership from AMSAT and IARU societies around the
world with the ISS space agencies partners: NASA, Russian Space Agency, ESA,
CNES, JAXA, and CSA.
ARISS offers an opportunity for students to experience the excitement of
Amateur Radio by talking directly with crewmembers on-board the
International Space Station. Teachers, parents and communities see, first
hand, how Amateur Radio and crewmembers on ISS can energize youngsters'
interest in science, technology, and learning. Further information on the
ARISS program is available at ariss.org.

Hello Aayush,
Starting out with very strong signals is probably a good idea even though
you can probably get any satellite
that you wish with a good ground station. Start out with AO-85 for FM
reception and AO-73 for SSB
reception. AO-73 is especially strong during local day time during
Mon-Friday (UTC). There is not
transponder turned on then, so all the power goes into the telemetry.
Both of these can be received with an HT (handheld with a simple antenna)
so you are very likely to receive
them on any station you have and optimize from there.
I would also suggest that you might find local colleagues in AMSAT-India
who would be able to tell you
things of local interest (what parts are available where, for example).
73,
Burns W2BFJ

I have recently bought a second hand ICOM ic-821h, that doesn't seem to be

sub band, I have no receive on the main one. Does anybody have any idea as

In addition to what others have said, don't forget the packet radio
digipeater aboard the International Space Station. It puts out 5 watts and
is on most of the time except for when they're doing EVAs. You can pick it
up with a handheld radio when it's overhead.

Do you have the Squelch level on the side you are receiving on all the way

Did I read somewhere that a particular set of commonly used Keplerian
data sets did NOT include AO-85 - due to the fact that that mission's primary
payload was "military" in nature?
If so - which set does NOT include AO-85?

Hi Clint,
I think that the only set that INCLUDES AO85 is the one produced by AMSAT.
ftp://www.amsat.org/amsat/keps/current/nasabare.txt
I have not found AO85 yet in any of the Celestrak or Spacetrack lists that I
used previously.
I am happy to be proven wrong of course!

You are correct. Only the AMSAT keps and those sourced from AMSAT will

Thanks Drew,
Just tried to turn off the sub audio and in the satellite mode it indeed
completely mutes any receive. While when I have the sub audio on and tx in
the sat mode, I still hear some noice, but never a signal that is there on
the frequency. I ruled out a desensing as I have also transmitted into a
dummy load and have the same behaviour.
