Hi Team,
Listened yesterday evening (04-10-2016) and tonight (05-10-2016) no
signals received.
Not on 145.980/CW nor on 437.455/AFSK
The satellite was in eclipse on both occasions.
With regards,

What are your plans?
When is the ISS Tour of NASA?
I plan on renting a car a week before the symposium, and staying a week

AMSAT tinkerers?
OUTERNET is a free worldwide Geostationary Satellite downlink system
designed to bring content to remote areas all over the globe. They have
six geostationary birds covering the entire globe EVERYWHERE. All you need
is a small 18? (or 36? in some very remote areas) to receive content via
your own home-made receiver based on a TV dongle and Rasberry Pi.
Is there anyone on AMSAT-bb that is already receiving this content? We?d
like to hear about how easy it is to set up a receiver.
We have some ideas on how this can be used to augment Ham radio in our
Emergency Response and remote operations missions. See

Hi Bob & everyone.
I have a partially obscured view at the angle required for geostationary
satellites but was curious to see if I could get Outernet's signal from
Inmarsat 4-F3, which is where Outernet's transmission originates from in
this area (USA East Coast).
For background, I had used a variety of antennas (patch, vivaldi, DirecTV
dish repurposed) to receive some of the various data streams from Inmarsat
4-F3 in the past, with varying results.
I ordered the combination patch antenna / LNA / SDR that Outernet has
assembled optimized for L-Band. That left only the software side to
configure.
The first option was zero-cost, which was to attempt to decode the Outernet
feed using their guided software install for an existing Linux computer.
This consisted of a number of apps working in concert.
The "receiver" portion worked properly - I did see a reasonable SNR and
mostly error-free data stream. Unfortunately, I never decoded any content
with the other apps either due to their alpha or beta stage of development
or my lack of linux expertise.
However, at the same time I was corresponding with a couple of other hams
who saw similar results with the "add on" apps for a working linux computer.
I have not dug any deeper with that method so as of now, for all I know that
branch of the software might have improved.
In stark contrast to my lack of success with the linux method was a turnkey
boot image that Outernet makes available for you to write to an SD card for
use in a Raspberry Pi. Consisting of a fairly lite linux OS, plus all the
apps required and optimized for Outernet use, this solution was very much
ready for production use.
I would say within 2 minutes of booting a new Pi-3 with the Outernet image,
content started downloading to the local storage on the Pi. I didn't have
to do a thing but figure out how to log into the web interface that is your
portal to the Pi. (web as in http; there is no internet connection,
naturally) It was as plug-and-play as you could possibly get... turn on the
Pi and point the antenna. Period. Content just starts downloading if you
have a decent signal. You connect to the Pi from another computer and any
files that have downloaded are available for you to view.
Of course the antenna / LNA / SDR was attached before I powered up the Pi
and positioned to have decent visibility in the right direction. And of
course it's easy to see that the better your RF receive situation, the
better will be the rate at which content is received.
Finally, using items already on-hand for other experiments, I replaced the
patch antenna with the TP-Link 2.4 GHz dish
(https://www.amazon.com/Directional-Parabolic-Connector-Resistant-TL-ANT2424B/
dp/B003CFATOW?th=1)
that you often see used by amateurs for experimentation. Never mind that
it's supposedly for a higher frequency and never mind that it's not
circularly polarized, I found that in conjunction with the LNA & SDR from
Outernet, I received a much stronger signal than with the patch antenna.
But in fairness, I have not made a comparison with a 100% clear view of the
sky.
I hope those very early and limited observations of Outernet's solution are
useful to you.

I took delivery of my outer net eq last night
We qualified the patch antenna, amp and dongle
Dongle is very stable
Picked up INMARSAT on the bonnet of my car just on patch
Lots of new signals
I now need to get frequencies and decoders going
Look on my website I have just added photos
Signals - are quite strong
about 45 degree beam
mine is 145 deg
Will report back when i decode

An International Space Station school contact has been planned with
participants at Sekolah Kebangsaan Jalan Pasar 1, Kuala Lumpur, Malaysia on
06 Oct. The event is scheduled to begin at approximately 18:24 UTC. The
duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be direct between OR4ISS and 9M2RPN. The contact should be
audible over Malaysia 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.
Total of students: 746 students
Total of teachers: 43 teachers
There is no amateur station in the school. The school is invited by National
Space Agency Satellite Ground Station with a call sign of 9M2RPN in
conjunction with "National Space Challenge Prime Minister's Trophy 2016" as
in past years.
Participants will ask as many of the following questions as time allows:
1. Is orbit speed always 17,300 mph?
2. What is the escape velocity to reach ISS?
3. When you have achieved orbit what is the first thing that you do?
4. What is microgravity ?
5. Can you weigh yourself in weightlessness?
6. How does one get treated in case of sudden sickness in space?
7. Does a shuttle orbit continually trace the same path across the earth?
8. Can shuttle change its orbit?
9. Do you sweat in space?
10. Can you grow seeds in space?
11. Can you see other satellites from the ISS?
12. What time zone do you observe in space?
13. How many sun rises and sunsets do you see in space?
14. How often you get to speak to your families in space?
15. How is garbage disposed in space?
16. How do astronauts train for launch, orbit and reentry?
17. How would a candle burn in space?
18. Can you blow your nose in space?
19. Do your ears pop when you launch?
20. Can you see stars in daytime when you are in space?

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
information, see www.ariss.org, www.amsat.org, and www.arrl.org.

Never mind that it's supposedly for a higher frequency and never mind that
it's not circularly polarized, I found that in conjunction with the LNA &
SDR from Outernet, I received a much stronger signal than with the patch
antenna. But in fairness, I have not made a comparison with a 100% clear
view of the sky.

I have not dug any deeper with that method so as of now, for all I know that
branch of the software might have improved.

much ready for production use.

naturally) It was as plug-and-play as you could possibly get... turn on the
Pi and point the antenna. Period. Content just starts downloading if you
have a decent signal. You connect to the Pi from another computer and any
files that have downloaded are available for you to view.
