John (vk2fak),
You said "Is there any details on the web about this type of helix, have
never seen
it with a ring reflector in books."
I've also never seen a helix ring reflector design in any antenna books. My
first home brew helix followed AF9Y's design exactly from his site
http://www.af9y.com/helix.htm which used a ring reflector.
My second build did not use PVC boom (too heavy) or copper tubing (too
expensive) but a 1 in. square metal boom and aluminum clothes line wire. I
kept the ring reflector.
This is the first time I've seen two reflectors used. It would be
interesting to discover who NASA's supplier is for this antenna and see the
spec's.
Regards, Mike

ARISS HamVideo Currently Not Transmitting
The HamVideo digital Amateur Television (DATV) transmitter aboard the
International Space Station (ISS) Columbus module recently ceased
transmitting. The unit's indicators show it is functioning but its signal
cannot be detected on the ground. The ARISS team's efforts to get the
transmitter working again have been unsuccessful, thus far.
A series of steps are currently being undertaken to try to diagnose the
problem. However, if an actual failure occurred, only a ground-based
evaluation will fully diagnose the problem. The ARISS International team is
working diligently to bring HamVideo back to full operation as soon as
practical. We have started coordination with our space agency partners and
with our sponsors to expeditiously troubleshoot the issue on-board and, if
necessary, troubleshoot and repair the device on the ground.
The HamVideo DATV transmitter has become a very valuable educational asset
that astronauts enjoy employing as part of the ARISS connection. Astronauts
Tim Peake, KG5BVI; Paolo Nespoli, IZ0JPA; and Thomas Pesquet, FX0ISS,
regularly utilized HamTV to inspire students and educators during ARISS
contacts scheduled as part of these astronauts' ISS missions. Australian and
European HamTV ground stations have been operational for receiving and
distributing DATV signals from the ISS, and in the US, HamTV stations are
under development. Several hams in Japan have set up ground stations that
have received HamVideo.
As more information becomes available on the HamVideo status and on any
potential repair plans, we will keep you informed through future news
releases and via messages on the ARISS web site www.ariss.org.
ARISS relies on its sustaining sponsors, along with many devoted individual
donors and ARISS volunteers, to support the day-to-day operations and to
help with related expenses. These supporters are instrumental in developing
and funding the build of our new radio systems. For everyone interested in
helping ARISS inspire, engage and educate youth, hams and the public through
amateur radio on the ISS, please donate to ARISS at www.amsat.org or
www.ariss.org.
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 the 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 infor
mation, see www.ariss.org, www.amsat.org, and www.arrl.org.

Subject: [amsat-bb] Upcoming ARISS contact with University of the
Philippines Integrated School, Quezon City, Philippines
Message-ID: <767A64B0EC2A4839AC78CAA424002EAF@???>
Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at University of the Philippines Integrated School, Quezon
City, Philippines on 15 May. The event is scheduled to begin at
approximately 08:22 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 W6SRJ. The contact should be audible over the west coast
of the U.S. Interested parties are invited to listen in on the 145.80 MHz
downlink. The contact is expected to be conducted in English.
The UP Integrated School (est. 1976) is the laboratory school of the UP
College of Education. It offers an integrated curriculum from Kindergarten
to Grade 12. It is one of the country's pioneer integrated schools and has
been offering an integrated curriculum from Kindergarten to Grade 10 since
its inception until the mandatory implementation of the Department of
Education's K-12 program in 2012. The UPIS is the product of the merging of
three schools whose functions it inherited. These are the UP High School
(est. 1916), the UP Elementary School (est. 1936), and the UP Preparatory
High School (est. 1954).
Age of students is 14 and 15.
Participants will ask as many of the following questions as time allows:
1. What are the challenges that astronauts face while working inside the
international space station? How are these issues addressed?
2. What can you give as an advice or words of inspiration to young aspiring
Filipinos dreaming of becoming involved in NASA's (or International) space
programs?
3. The Philippines is one of the most disaster-prone (typhoon, earthquakes,
and volcanic eruptions) countries in the world. What researches does the
ISS have to help these countries (or the Philippines, in particular)
minimize risks related to such disasters?
4. Which of the recent breakthroughs/discoveries in your research in the ISS
is your team's favorite and why?
5. Given the latest discoveries/experiments your team has done in the ISS,
which field in science and technology do you think has the most promising
advancement in the upcoming years?
6. How can the youth have a more active participation in space programs?
(Skills training, seminars, etc.)
7. How long does it take to get use to the weightlessness in space?
8. What did you do before you became an astronaut?
9. Compared to Earth-based monitoring programs, how does the ISS facilities
and equipment help in monitoring environmental disasters?
10. What can the Philippines do if it wants to participate in international
space programs?

Thanks for the info!
Adding some details and one question.
IRAZU telemetry is FSK9k6 at 436.500 MHz source: [1]
UBAKUSAT telemetry is GMSK9k6 at 437.325 MHz source: [2]
1KUNS-PF telemetry is FSK9k6 at 437.300 MHz source: [3]
The question is about UBAKUSAT, in some sites like IARU's one [4] refers
that CW is at 427.225 MHz, while in other sites like amsat-uk's one [5]
refers it at 437.225. Any idea which is the right one?

Hey Graham,
So, it is 437.225 MHz. Thanks for making it clear!
73,

Following the latest ISS TLE it seems (need confirmation from the
satellites teams) that:
IRAZU is alive and transmit FSK9k6 [1]
UBAKUSAT not heard yet [2] but the only observation until now was
probably too close to deployment.
1KUNS seems to be alive but it doesn't seem to transmit FSK9k6 [3][4]
except if this is a drifted signal from UBAKUSAT that should transmit
+25KHz from the observed frequency.
I guess soon we will need new tle, please share any news/updates.
Thank you,
fredy
