International Space Station Astronauts are Calling CQ ARISS Students
??? ARISS-US program?s education proposal window open Oct. 1 - Nov. 30, 2018
?
September 25, 2018:? ARISS is seeking proposals beginning October 1, 2018
from US schools, museums, science centers and community youth organizations
(working individually or together) to host amateur radio contacts with an
orbiting crew member aboard the International Space Station (ISS) between
July 1 and December 30, 2019.
?
Each year, ARISS provides tens of thousands of students with learning
opportunities about space technologies, communications, and much more
through the exploration of Amateur Radio and space. ARISS has been pleased
of late, to be one of many possibilities of interest to educators during
NASA?s A Year of Education on Station, which celebrates an almost 12-month
presence of a teacher aboard the ISS.? The ARISS program connects students
to astronauts on the ISS through a partnership between NASA, the Radio
Amateur Satellite Corporation, the American Radio Relay League, other
Amateur Radio global organizations and the worldwide space agencies. The
program?s goal is to inspire students to pursue interests and careers in
science, technology, engineering, and mathematics (STEM) and in Amateur Radio.
?
Educators report regularly that student participation in the ARISS program
stimulates interest in STEM subjects and STEM careers. One educator wrote,
?Many of the middle school students who took part in and attended the ARISS
contact have selected science courses in high school as a result of that
contact.?? Educators are setting up ham radio clubs in schools and learning
centers because of students? interest.
?
ARISS is looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed, exciting
education plan. Students can learn about satellite communications, wireless
technology, science research conducted on the ISS, radio science, and other
STEM subjects. Students learn to use Amateur Radio to talk directly to an
astronaut and ask their STEM-related questions. ARISS will help educational
organizations locate Amateur Radio groups who can assist with equipment for
a once-in-a-lifetime opportunity for students.
?
The proposal window opens October 1, 2018 and the proposal deadline is
November 30, 2018.
For proposal guidelines and forms and more details, visit:
http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html
?
Proposal webinars for guidance and getting questions answered will be
offered October 11 and October 23, 2018, both at 8 pm Eastern Time. Advance
registration is necessary. To sign up, go to:
ariss-proposal-webinar-fall-2018.eventbrite.com/

Mark, you suggested that you would ". . . avoid the diplexer like the
plague." Why exactly?
I use a Comet CFX 4310C at each end of 60' of cable.
.3dB not 3 dB of insertion loss.
CFX-4310C
2M/440/1200MHz Triplexer
Band Pass Loss Max Power
1.3-150MHz .25dB 1000W PEP
350-500MHz .25dB 500W PEP
840-1400MHz 0.3dB 200W PEP
Isolation: 50dB
One run of cable and one surge protector with three antennas. In operation
for 25 years with no problems.

Subject: Re: [amsat-bb] Station advice: coax
With that kind of coax run, you'll definitely want the lowest loss feedline
you can afford, and you'll probably want the pre-amps sooner than later. If
hard line is out of the picture, LMR 600 is a good alternative. Several
outlets will sell custom lengths with connectors attached. You can get by
with LMR 400 or Belden 9913 on the 2 meter side, but loss at 435 MHz will be
greater. I would avoid the diplexer like the plague.
As GEO mentioned, you really only need the flexy stuff at the point where
things are rotating. I run LMR 600 to the pre-amp, just below the rotor, and
ultra-flex from the pre-amp to the antenna. A good, moderate-cost
alternative for pre-amps are the "Mini" pre-amps from SHF Elektronik in
Germany http://www.shf-elektronik.de/en/

Triplexer/Duplexers work quite nicely for most satellite operations. At
least for the LEOs and AO-7.
Comments like "plague" paint with too broad a brush and are not
technically sound.

International Space Station Astronauts are Calling CQ ARISS Students
??? ARISS-US program?s education proposal window open Oct. 1 - Nov. 30, 2018
?
September 25, 2018:? ARISS is seeking proposals beginning October 1, 2018
from US schools, museums, science centers and community youth organizations
(working individually or together) to host amateur radio contacts with an
orbiting crew member aboard the International Space Station (ISS) between
July 1 and December 30, 2019.
?
Each year, ARISS provides tens of thousands of students with learning
opportunities about space technologies, communications, and much more
through the exploration of Amateur Radio and space. ARISS has been pleased
of late, to be one of many possibilities of interest to educators during
NASA?s A Year of Education on Station, which celebrates an almost 12-month
presence of a teacher aboard the ISS.? The ARISS program connects students
to astronauts on the ISS through a partnership between NASA, the Radio
Amateur Satellite Corporation, the American Radio Relay League, other
Amateur Radio global organizations and the worldwide space agencies. The
program?s goal is to inspire students to pursue interests and careers in
science, technology, engineering, and mathematics (STEM) and in Amateur Radio.
?
Educators report regularly that student participation in the ARISS program
stimulates interest in STEM subjects and STEM careers. One educator wrote,
?Many of the middle school students who took part in and attended the ARISS
contact have selected science courses in high school as a result of that
contact.?? Educators are setting up ham radio clubs in schools and learning
centers because of students? interest.
?
ARISS is looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed, exciting
education plan. Students can learn about satellite communications, wireless
technology, science research conducted on the ISS, radio science, and other
STEM subjects. Students learn to use Amateur Radio to talk directly to an
astronaut and ask their STEM-related questions. ARISS will help educational
organizations locate Amateur Radio groups who can assist with equipment for
a once-in-a-lifetime opportunity for students.
?
The proposal window opens October 1, 2018 and the proposal deadline is
November 30, 2018.
For proposal guidelines and forms and more details, visit:
http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html
?
Proposal webinars for guidance and getting questions answered will be
offered October 11 and October 23, 2018, both at 8 pm Eastern Time. Advance
registration is necessary. To sign up, go to:
ariss-proposal-webinar-fall-2018.eventbrite.com/

Hi,
We are starting to commission the warehouse and it should be appreciated if
all users of the Nayif-1 Dashboard
would point the dashboard URL to http://data2.amsat-uk.org
We will mop up any data that is sent to the existing warehouse and update
the scores appropriately (may not be
immediate as we have a lot on our hands).
As FC1 has significantly more data to migrate we are going to hold off on
that.
