An International Space Station school contact has been planned with
participants at Templestowe Valley Primary School, Templestowe, Victoria,
Australia on 19 Mar. The event is scheduled to begin at approximately 08:43
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 VK4KHZ. The
contact should be audible over portions of Australia 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.
Templestowe Valley Primary School is located in the Eastern suburbs of
Melbourne (about 17km from the centre of Melbourne). We have approximately
460 students from age 5 to 13 years. We have about 45 on our staff which
includes 19 grades. Our students are loving learning about Science and STEM.
They have a strong love of sports especially soccer, cricket, and
basketball. We have a friendly and inclusive community.
Participants will ask as many of the following questions as time allows:
1. If you could take 5 personal things to space what would it be? Did you
take your guitar?
2. How fast do you need to go in a rocket to break through the Earth?s
atmosphere?
3. What is the most extraordinary thing you have seen in space?
4. Have you ever been in a space emergency or felt scared?
5. How does the space ship move without hitting something?
6. How many astronauts can work in the space station and what do they do?
7. How did the space station get into space?
8. What is the greatest risk to your space station?
9. Have you discovered anything new?
10. How do they fuel the spaceship?
11. What are you researching in space?
12. How does your body feel when you re-enter gravity?
13. What do you have to do to train or prepare to go to space?
14. How do you have a shower and wash your hair?
15. What do you eat?
16. Why do you need to exercise?
17. When you use amateur radio in space are conditions better or worse?
18. How long does it take for ISS to orbit Earth?
19. How long can you stay in space?
20. Is the ISS at risk of being hit by a meteor?

About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the Center for the Advancement of Science in
Space (CASIS) and National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,
teachers, parents, and communities learn about space, space technologies,
and amateur radio. For more informa
tion, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,

Not only is the equipment to get on linear satellites more expensive, they
also require more skill to operate OR even more equipment for automatic
control (if your equipment can be controlled). That is why the FM
satellites are so busy, inexpensive hardware + lower skill requirements =
more people will try it.
The SDR market will surely help on the receiving side, but it is the
transmission side that causes the big hurdle.
Hopefully with the coming warmer weather I'll be able to get more
experience with my linear setup. It is not all that great standing out in
below freezing temperatures with wind and attempting to learn how to
operate two radios and hold an arrow at the same time.

Why not use the new LimeSDR Mini and do a SDR-based design for satellite
work? It already has separate TX and RX paths, ready for duplex operation.
One simply, for various values of simple, needs to design a
receiver/transmitter design to go into the Altera FPGA, bolt on a
suitable CODEC (might I suggest the MAX9860?), and then add some
filtering and a PA.
[Mic/Spkr] <---> [MAX9960] <---> [FPGA] <---> [Limechip] <--> PA/Filter
I'd bolt on a LCD, rotary encoder, and a few buttons for user I/O. No PC
needed for control. Add antenna and you're done.
You'd have a complete all-mode (SSB, AM, FM, etc.) solution for perhaps
$200.
(This is a back-burner project for me -- I won't be offended if anyone
gets there first. hihi)

Does FoxTelem automatically check for new Keps periodically, or only upon
startup? I have an unattended station running on a Raspberry Pi, and I'm
wondering if I shouldn't close and restart FoxTelem every couple of weeks
to refresh TLE's. Scrolled through the command terminal and didn't see
any updates occuring, but you can see keps being updated upon startup.

Hi Daniel,
I also find it a bit hard to believe that the current Outernet goal can
be made to work: a 30kbps stream from a GEO Ku-band satellite that can
be received with a bare LNB or small patch antenna. This is not
necessarily impossible if you run the numbers, but its feasibility is
pretty borderline. I'll believe it when I see it working.
As I understand, one of the main issues they're having is co-channel
interference. This goes as follows: if you look at link budget alone
(free space path loss, the gain of an LNB and so on), maybe things can
look OK. However, in the real world what happens is that your LNB has a
wide beam, so you receive the signals from over a dozen different GEO
satellites. The signal you want to receive is now interfered by DVB-S
transponders (or other signals) from many different satellites and now
you have a problem (as before the main contribution of noise was the LNB
noise figure, and now you notice that the noise floor is much higher due
to interference).
This is not a problem when using a dish, since the beamwidth is rather
narrow and your dish only sees a few satellites at a time, so
interference is unlikely. But when you look at many satellites instead,
the spectrum is extremely crowded.
The fun thing about this story is that they claim that the are
experimenting with LoRA to fight co-channel interference (since LoRA is
spread spectrum). In my last talk about Outernet I commented that this
is nonsense and that they don't understand properly how spread spectrum
works.
If you think about it, spread spectrum (in comparison to a narrowband
signal) works very well against narrowband interference, but it doesn't
make any difference against wideband interference. In this case, the
co-channel interference is DVB-S and other wideband signals. For all
practical effects, they just look as an elevated noise floor and there
is no way to fight against them, spread spectrum or not.
Since the Outernet topic has come to this mailing list once again, I
take the liberty to remind you that while Outernet can be interesting
from the technical point of view, they have always kept secret their
modulation, coding, protocols and so on, and the key parts of the
receiver are closed-source. This is no good for Amateur Radio and
experimentation in general.
Thanks to my work and the help of some other people, now there is a
fully open-source receiver for the (now defunct) L-band signal, as well
as public specifications for everything. This was done by reverse
engineering, without any support from the Outernet team (which don't
seem to like this open-source receiver).

Don,
Be careful about making suggestions about increasing activity on the
Linear SATs! You may get personally ATTACKED in direct e-mails like
I did. There are people out there that hate Gridders and feel the Linear
SATs are to be held aside so they can have them to themselves for having
chats with each other day after day.
I won't reveal the gentleman's ID, but you can read excerpts of some of
the e-mails that came to me directly for merely suggesting something to
increase activity on his private Linear SATs. Or, save your blood pressure
and skip his comments below. (So much hate!)
73, Bob K8BL
---------------------------------------------------------------
Simply stated you are the problem with this hobby today.
Go get in your car and prove the laws of propagation again and again
from strips of dirt only people like you care about. Yeah that?s real modern
HAHAHAHA
Talk to your same cronies over and over yelling a new grid at them. You call
that
fun ?eh. Sats work, get over it, you don?t have to keep proving it. It
simple to
understand that.
Once again I say we don?t need your kind on the linear sats. Stay on FM and
do us
all a favor.
The mess I refer to is the operating practices of those on the FM birds.
People calling
over one another, not allowing someone to get a confirmation of their
contact before yelling
their call and grid out once again, and now I hear you have a jammer on 91
and 92. What
frustration do you think is causing that ?
I don?t care what other hams do. Each have their own preferences,.. What I
don?t like is
someone coming up with a great ?idea? to get more activity on what is now an
enjoyable
aspect of the hobby that I enjoy. I have to put up with nonsense contests
every weekend
on HF but I can go to WARC bands to get away from it. Don?t be looking to
crap up my
linear sats and turn them into the mess that?s on the FM sats. Its
disgraceful what goes
on there. Honestly I don?t think it will come to that since people have to
use more that
a pair of $25 boufangs and an arrow to get on linear sats.

>>> I read the bb almost thoroughly throughout the day. A small common
denominator is subtly appearing. I read, "I was on the bird all alone", or
something like, "no one to talk to". The unusual conclusion, we have too
many satellites! I never thought this ham would even think of it. If I
look at Satpc32 with "only" a dozen listed, in fast forward a bewildering
barrage of circles floats across the screen. I am not saying this is a bad
thing, it just spreads us out and at times, there is, "no one to talk to".
I do testing like try different power levels, talk to myself til as close to
AOS as I can get. You know the drill. From what I read there are more on
the starting block. I'd like to see more L band time, maybe a bird with a
S band DL a MEO, a HEO- I know, idle comments. We have the five & dime
coming at us, which sounds like a whole other world, I'm looking forward to
it. Then there is the massive off air time making all this stuff work.
Currently testing between t
wo
>>>L band antennas and between two different 70cm antennas. At this time I
have my Satpc32 talking fine with the radio but not with the rotor. A com
port issue which currently I can not figure out. Assistance solicited. On
the ISS it would be fun to see one of the "hams" up there have that
"burning in the belly" to yuck it up, get WAS, VUCC, DXCC or whatever.
Again, just idle comments not a criticism of the ARISS system. Sunny day in
Seattle, xyl says yard work.

Hi Bob,
> You may get personally ATTACKED in direct e-mails
Yeah, sometimes there is a bit of boorish behavior, it seems more via the
internet than in direct conversations. I've shrugged off, or laughed off
some interesting replies over the years ...
When I reported in the ANS bulletins AMSAT-DL's success using their big dish
to accomplish the Earth-Venus-Earth path I received an e-mail from an
Official Observer citing me for promoting poor amateur radio practices. No
regular ham has a 20 meter dish and temporary authority to experiment with a
few kilowatts on S-band.
When I mentioned that ARISSat-1 was in a way a Russian satellite since it
had a Russian callsign, the experiment on board was by a Russian university,
it was deployed by Russian cosmonauts on a Russian EVA ... I was warned by
private e-mail that he was considering suing me if I kept promoting such
un-American thoughts like that.
A private e-mail informed me that AMSAT had been taken out of that
individual's will because of stuff I said.
I hear you on the satellites often. I spend most of my time tweaking my
telemetry reception but I still hear the voice traffic ... you keep handing
out the grids :-) Since telemetry doesn't count for Field Day I'll be
switching over to voice on the linear sats so there goes the neighborhood
for sure!
