Any chance we can get some way to get the list of satellites as well as the
current status data in JSON? This would make it a whole lot easier to
develop our own interfaces and would also reduce overhead without having to
transfer the entire page.

Alan,
You mention documented "sweet spots"? can anybody point out where we can
find this information.??
I saw something on the AMSAT-BB many years ago but never could find that
email again.

I'm sure there is an opening for a JSON volunteer if you're up to it.

The XW's and CAS-4'S are loud and easy to use, in my opinion. I have
managed varying levels of success with AO-7, it is my linear unicorn; as
AO-85 is my FM unicorn.
Even with the lower 48 mostly being in a XW/CAS-4 pass they can be full of
dead bandpass.

If you tune the passband, you hear three peaks of noise - at
approximately 145.928, 938, and 958. Although some like to avoid them
due to noise, they are actually the most sensitive areas of the
transponder. 938 is very popular with low power rovers for this reason
since a low power signal at low elevation can be much louder there
than at the center of the transponder.

FOR IMMEDIATE RELEASE
9 US Schools Moved Forward in ARISS Selection Process
September 10, 2019 -Amateur Radio on the International Space Station (ARISS)
is pleased to announce the schools/host organizations selected for the first
half of 2020. A total of 9 of the submitted proposals during the recent
proposal window have been accepted to move forward in the processes of
planning to host a scheduled amateur radio contact with crew on the ISS. The
primary goal of the ARISS program is to engage young people in Science,
Technology, Engineering, Arts and Math (STEAM) activities and raise their
awareness of space communications, radio communications, space exploration,
and related areas of study and career possibilities.
The ARISS program anticipates that NASA will be able to provide scheduling
opportunities for the 9 US host organizations during the January to June
2020 time period. They are now at work completing an acceptable equipment
plan that demonstrates their ability to execute the ham radio contact. Once
their equipment plan is approved by the ARISS Technical Mentors, the final
selected schools/organizations will be scheduled as their availability and
flexibility match up with the scheduling opportunities offered by NASA.
The schools and host organizations are:
Celia Hays Elementary School
Rockwall TX
Golden Gate Middle School
Naples FL
J.P. McConnell Middle School
Loganville GA
Kittredge Magnet School
Atlanta GA
Maple Dale Elementary School
Cincinnati OH
Monroe Carrell Jr. Children's Hospital at Vanderbilt
Nashville TN
Oakwood School
Morgan Hill CA
Ramona Lutheran School
Ramona CA
River Ridge High School
New Port Richey FL
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 ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

My plan was to volunteer to develop a mobile app, the status page isn?t the
easiest to use on a phone. There are also other features that could be
incorporated like automatic grid field population, alerts on status changes
(think AO-7 mode flip), etc.
Web development is one of my weaknesses but I?ll do it if I have to.

Cool! I've been working on seeing how mobile friendly we can bulletin
display. Your idea for an operator-focused app seems very timely. So far the
bulletin display on mobile devices that we've got hacked out is whatever
WordPress does to color within the lines.
Android Studio has been limited usefulness to me ... perhaps I'll need to
get smarter.
Let's see what cooks up :-)
