Ok Guys
I have the IC 9700 working on sat32 using the setup:
IC 9100
19200
address of A2H and cat speed 50
The radio frequencies were reversed but after a few times of flipping them
on the radio it started tracking the program ok. It appears to be working
just waiting for a operational sat to come over now.
As for the radio it seams to be ok on fm and dstar. You have to load
memories using cloning software. I loaded a couple local repeaters and found
the icom CS 9700 is not transferring some data such as tone and duplex
setting. I plan to ask Icom next week.
Lots to learn yet.

I fixed the issue. Download the new version at the usual place or directly
here:
http://www.g0kla.com/pacsat/PacSatGround_v0.22.zip
This just corrects the problem on some versions of Java. It also fixes
some issues with small fonts on high DPI displays. Let me know if there is
any issues with font sizes.
thanks

Hello All,
Another weekend in the parks.? During Sunday the 14th and Monday the
15th of April,
I intend to operate from more national parks in VK3 in grids QF23 and QF24.
These will be Greater Bendigo, Barmah, Lower Goulburn and
Heathcote-Graytown National Parks.
FM and linear birds, depending on what is above my horizon at the time.
Hope to catch you on the birds.

Runs perfectly on Ubuntu 18.04 (on an old HP laptop).
However on my Pi 3 running Raspian Jesse, I get the "unable to download or
write TLE's" error. This is the same pi that I have running FoxTelem
24/7, if that matters.

I wanted a simple program that showed when target spacecraft would be above
the horizon. I remembered a picture of an old program that Rob Bruninga
posted on AMSAT-BB some time ago. I could not find that picture, but I built
something similar and it looks like this:
http://www.g0kla.com/klatrack/klatrack_dark.png
It's a simple program that plots the elevation of upcoming satellite passes
as a horizontal display and then updates it in real time. It does a one
time calculation to fill its buffer of positions, then its pretty efficient
because it just calculates the next position it needs in the future.
The details and the download are here:
http://www.g0kla.com/klatrack/index.php
Thanks again to Dave Johnson (G4DPZ) for his port to Java of John
Maglicane's (KB2BD) predict library.
The is made available under the Gnu GPL and I will upload the code to github
when I get a chance.

Subject: [amsat-bb] Non standard APRS implementation in AI SAT

There was a discussion, in another group, about why nothing from AISAT was
getting showing up on aprs.fi.
K4KDR provided some samples of the signals so they could be analyzed.
The direwolf "-dp" option was used to produce a hexadecimal dump, of the
frame, so we could see what is going on.
---------------------------------
Notice the extra comma after the last address.

digi 1 AISAT* 0 h=0 res=3 last=0 <-- The ?h? bit indicates that the
digipeater address has been used
It should be 1 in this case.
There should NOT be
the * character in the address

digi 2 0 h=0 res=3 last=1
I reformatted this so the bytes would be in groups of 7 so it is easier to
read.

-----------------------------------
This is my analysis:
(1) Digipeating does not work normally. A digipeater should only change the
via path. The information part should not be changed. Why is it converted
into ?message? format?
(2) Only the needed digipeater fields should be present. If they are not
needed leave them out. Don?t fill them with blanks.
(3) A station address should never contain the * character. That is only in
the human readable standard monitoring format. The * after a station
indicates that the H bit is set.
(4) When a digipeater uses up an address in the via path, it must set the
?H? bit to 1. If it responded to an alias, it should substitute its own
callsign.
Here is an example of expected behavior:
K4KDR-6>CQ,ARISS:=3747.66N/07736.67W`de K4KDR scott23192@?????.??? Virginia
FM17es
K4KDR-6>CQ,RS0ISS*:=3747.66N/07736.67W`de K4KDR scott23192@?????.???
Virginia FM17es
- ARISS is recognized as an alias by RS0ISS.
- RS0ISS substitutes its own call and marks that digipeater field as being
used.
- The * is not a character in the address. It is the human readable way to
indicate that the ?H? bit is set.
- Only the via path is changed.
- The Information part is not changed at all.

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
https://ariss-proposal-webinar-spring-2019.eventbrite.com
