For some reason mail from this list with the above subject from Chris is
not getting into my mailbox. Luckily I check the web based archive every
now and then.
Chris, thank you for updating the PacSat software and fixing the Java
problem. Version 0.22 is starting up without any problems now. I use UDP
streaming from GQRX into direwolf and the PacSat software can read the
KISS data via TCP on port 8001 then. Every time v0.22 is starting up it
still complains that I need to set up a virtual serial port, but the
ignoring the warning seems fine. It shows a 'decoder ready' message, so
I assume that means it's working.
Reading the manual now as I have no experience with PacSat. Waiting for
a good pass of Falconsat-3 tomorrow to see if I can get some data in.
Data out is for another day.
73 and cheers,
Hans

SSTV app works great. Use ear phones and put them on the end of the phone
where the microphone is located. Adjust the audio and you can get perfect
SSTV pictures from the space station.

During his career developing techniques with his team to do Very Long
Baseline Interferometry using widely separated but not connected radio
telescopes, Tom Clark, K3IO made major contributions to Radio Astronomy
Science and Engineering.
Today, we saw another outcome. NSF, EU, and many others announced the VLBI
generated image of the 4 billion solar mass Black Hole at the center of the
Galaxy Messier object 87 (M87 for shorthand). You could literally see all
the way down to the event horizon. The used telescopes all over the world
and made the signals coherent even though they were recorded using a record
and timing process developed by Tom and his team at NASA Goddard and
extended into the modern era with better toys than Tom had when he was the
world's most accurate geodicist.
And once again, Einstein's theory of relativity was proven right in the
most violent laboratory ever "seen".

Hi!
I will have an AMSAT booth at the Arizona Amateur Radio Club's annual
hamfest on Saturday, 20 April 2019, in the morning. The hamfest is held
at the DeVry University, along Dunlap Avenue east of I-17 exit 207 in
Phoenix. The hamfest is a morning event, scheduled to run from 6am to
11am (1300-1800 UTC).
During the morning, WD9EWK will be on the air for demonstrations of
satellite operating. The hamfest site is in grid DM33, in Arizona's
Maricopa County. If you hear WD9EWK on the air that morning, please
call and be a part of the demonstration. All QSOs will be uploaded to
Logbook of the World after the hamfest. QSL cards are available on
request - no need to first send me your card or SASE; just e-mail me
directly with the QSO details for verification against my log.
I will use my @?????? Twitter feed to post updates from the hamfest.
For those who don't use Twitter, these updates are available in a web

Hi!
I will have an AMSAT booth at the Cochise Amateur Radio Association's
hamfest on Saturday, 4 May 2019, between 7am and noon (1400-1900 UTC).
The hamfest is held at the club's "Green Acres" site in Sierra Vista,
Arizona. "Green Acres" is located along Moson Road, south of AZ-90
and east of Fort Huachuca. More information about the hamfest is
available at:

A map of the hamfest site and the Sierra Vista/Fort Huachuca area is

If you?re interested in seeing what the Geochron4K clock looks like with the
real-time amateur satellite overlay, I?ve uploaded a sample picture at the
following URL:
https://on.frame.io/secuj3k8
Note that you can select which satellites to display. They are grouped first
into categories such as military, GPS, etc?and then the software offers the
ability to select individual satellites.
You can also alter the length of the ?trail? that appears behind each
satellite. The trail helps you to visualize the direction of travel.
Since Geochron is constantly updating the available overlays, and will soon
offer a software developers kit (SDK), there is no telling what kind of
information you may be able to overlay your clock.
I know that the company plans to add real-time weather, radio propagation,
and other overlays soon. If enough satellite operators chime in, we may be
able to get them to add footprints to the satellite overlays.
At $399, plus the price of a monitor, it?s a great tool for hams. I have no
financial or other relationship with the company, just a fan.
You can learn more at:
https://www.geochron.com/4k/
If you decide to buy one, please mention AMSAT in your order. Always good to
let vendors know where the business is coming from.

International Space Station Astronauts are Calling CQ Students
ARISS-US program?s education proposal window is open April 1 - May 15, 2019
?
March 24, 2019:? The Amateur Radio on the International Space Station
(ARISS) program is seeking proposals beginning April 1, 2019, from US
schools, museums, science centers and community youth organizations (working
individually or together) to host radio contacts with an orbiting crew
member aboard the International Space Station (ISS) between January 1, 2020
and June 30, 2020.
?
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. 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 April 1, 2019 and the proposal deadline is May 15,
2019. For proposal guidelines and forms and more details, go to:
http://ariss-proposal-webinar-spring-2019.eventbrite.com
Proposal webinars for guidance and getting questions answered will be
offered April 11, 2019 at 7 pm Eastern Time and April 16, 2019 at 9 pm
Eastern Time. Advance registration is necessary. To sign up, go to
