JAXA announced Guatemalan 1st satellite Quetzal-1 deploy from ISS
1520z 28th April.
The live will be on YouTube JAXA channel at 1445-1540z.
https://www.youtube.com/watch?v=7M39SjJJsEc
Quetzal-1 is 1U CubeSat. She operates on amateur band.
http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=653
This is J-SSOD#13 mission. G-Satellite is also J-SSOD#13 mission.
There is no her deployment info.
G-Satellite is 3U CubeSat. She does not operate amateur band, but very
interesting satellite. G-Satellite deploys miniature figures of Mobile
Suite GUNDAM and Char ZAKU in orbit and sends messages from space
about the Tokyo 2020 Olympic Games.
It might be postponed until the Games.

Gentlemen, just getting back into Satellite work - used to work AO-13
regularly with a pair of KLM twists, GASFET preamps, Yeasu 726R and Mirage
amps plus a KCT tracker. Now trying to get my newly built LVB tracker to
work with SAT32PC
I?ve read the post and response in the archives from 2018 concerning
interfacing the LVB tracker to Sat32PC which was a big help (thank you!),
but my issue is that while Sat32PC can now control the azimuth via GS-232
commands over a serial port, the tracker is ignoring elevation commands. I
have calibrated the (90 degree) elevation rotor multiple times and stored to
EPROM, but no joy to any of the GS-232 elevation commands, even when I issue
them directly from a Putty ap via the com port. I can read back the
calibration offset values and the rotor position, but none of the commands
to the rotor to change elevation work. I know the elevation rotor interface
is working because I can move the rotor with the LVB push buttons.
Although I just built this interface (from an AMSAT UK kit), the design is
>15 years old and emails to the designer have gone unanswered. Any help
would be greatly appreciated as I?m out of ideas.
Thanks and 73

Hi,
End of day and we have a working server in a closed environment.
All UI elements are working but we have to test upload. Will do that in the
morning and if all goes well we should be collecting data again by midday UTC
As you can imagine we have moved quite a lot of data but it went smoothly.
Once again thank you for you patience.

Out of curiosity - what is the status of this bird? It shows up in the NASA
orbital info, but not in the Amateur in the SatPC32 tracking selections.
The German Orbital Systems site does not elaborate on some of the details.
particularly if one wished to configure a D-Star rig and try it. With
IC-9700's proliferating I would expect some noise if it is accessible.
Any info or help would be appreciated.

Following up on the previous discussion, I too heard a ragchew on AO-92
during the 4/26 15:20 pass, and others heard it on the 4/27 02:00 pass. I
checked for repeaters in New England with a 67 Hz CTCSS tone, and W1RJC in
New Bedford comes up. Its output at 145.110 MHz also uses a 67 Hz tone and
would have a third harmonic at 435.330 MHz, just about right for AO-92
considering doppler. It is also consistent with hearing a NH callsign and
discussions about sea vessels :)

AnInternational Space Station school contact has been planned
withparticipants at NorthernVirginia Schools Group, Woodbridge VA on30
April. The event is scheduled to begin at approximately 13:35 UTC.It is
recommended that you start listening approximately 10 minutesbefore this
time. The duration of the contact is approximately 9minutes and 30 seconds.
The contact will be a Multi-Point Telebridgebetween NA1SS and AB1OC.
Amulti-point telebridge contact means that each student will be on
thetelebridge from their own home. Thecontact should be audible over the
state of New Hampshire andadjacent areas. U.S. Interested parties are
invited to listen in onthe 145.80 MHz downlink. The contact is expected to
be conducted inEnglish. Watchfor live stream at: https://youtu.be/Cu8I9ose4Vo
Story:
Weare students from Northern Virginia. We are ages 5-10 years old andwe are
in K-5th grade, in Woodbridge VA, just outside of DC. Ourschool year was
ended on March 13th and we have been home learningmany things using distance
learning methods. We have been learninghow to get along in small spaces with
little contact with the rest ofour community. We are learning quickly how it
must feel to be on theISS!
Participantswill ask as many of the following questions as time allows:
1.What does the sun look like from outer space?
2.How comfortable is it to sleep in space?
3.What is one thing you want to eat when you get back to earth?
4.I've heard that stars are red, yellow and blue. Can you see thosecolors in
space when you look at the stars?
5.Besides your family, what do you miss most while being in space?
6.What are your thoughts on our Covid-19 situation right now? Does theEarth
look differently over the last 3
monthsnow that many people are inside and not creating pollution?
7.How often do you get to go out of the ISS? Have you been on anyspace walks?
8.Who makes the rocket that takes you to the ISS?
9.What does it feel like to float all the time?
10.Do you use flashlights on space walks?
11.How do you exercise in space?
12.How do you get out for space walks safely without the air from theISS
coming out into space? How does it
feelto walk in space?
13.What do you wear in the space station?
14.How did it feel when you first got to space?
15.How is space different from Earth?
16.What do you study in school to become an astronaut?
17.What do you like the most about being in space?
18.Were you nervous when you launched into space?
19.How do you communicate with loved ones while you are in space?
