Hi folks,
is there anything that does what trakbox does that can substitute it?
I mean something that tracks the satellite moving automatically the rotators
and
The radio frequencies?
Thanks

I presented yesterday at Tampa Hamfest AMSAT forum K3NG's Anthony Good's
arduino controller
I've built 6 of these things, they work great:
https://blog.radioartisan.com/yaesu-rotator-computer-serial-interface/
It's almost as much effort to get the 2 line display hooked up as it is to
get the 2 sense lines from the controller and the 4 (up/dn/lt/rt) drive
lines. I've never put buttons on one for up down left right because there's
already buttons on the g5400
I have built them without display also, just have to use a terminal
emulator to connect and query the measured position)
Get the yaesu GS232 manual for the command listing. That's what it's
emulating.
Did I say it can be quite inexpensive to use an arduino? Lots of fun and
satisfying to build too.
Thanks,
Mike

Restuffed the LVB tracker with an Arduino
Mega. Reused the buttons and 16x2 LCD.
Cost around $35 retail. Sun track, moon track, gps, ancillary pins
feature enabled. Drive a digital pin (preamp, relay, etc) from
Satpc32's serial console.
Simple to do. Used an IIC display for this one:

Please pardon the newbie question, but I?m trying to get active on the birds
again during the holidays after being off the air for well over a year.
During that time, several new birds have been launched. It?s hard to keep
up?and made more difficult because each satellite has multiple designations
(names.)
Depending on the application that you?re using, such as SatPC32, you may not
find the satellite using the name listed on one of the sites designed to
keep us all abreast of current activity. Adding to the confusion, many web
sites list birds that are technically active (such as in beacon mode, or
downloading telemetry) but not available for amateur use.
Can someone provide a short list of the current active satellites for both
FM and SSB/CW available for amateur use? I?d be most grateful. If the run of
launches continues, we?ll need to update the ?Getting Started? booklet
quarterly! :-) Good problem to have.
Thanks in advance. Hope to work some of you during the next few days.

Today, December 12, 2016, marks the 18th anniversary of the activation of
the MIR SSTV Amateur Radio developed System which was transported and put
aboard the MIR Space Station. The MIR SSTV System sent pictures over a
period of about 2 years and 4 months to the delight of Amateur Radio
Operators and others worldwide. (Mir was deorbited in March, 2001) For those
interested in this historical event and background, the publication Amateur
Television Quarterly (ATVQ), Spring 2015 issue has an article, ?How Did the
MIR SSTV System come into Existence?? Back issue copies of ATVQ containing
this article are available via WA6SVT@xxx.xxx. See also web address:
www.ATVQuarterly.com.
A small sampling of perhaps thousands of received pictures may be found in
web sites:

Background information and initial efforts on developing the MIR System and
early efforts to provide SSTV for the ISS may be reviewed at:

I need some help with SatPC32. I have been using it for some time (over
a year) with no problems but now it is looking for a serial port I don't
have. I am using a Yaesu G-5500 rotor which should be on port 10 but it
some how got changed to port 13. I tried to access the help for Yaesu
rotors (? - hints - rotor - Yaesu g-232) but it won't open. How do I
change it back? I'm having a CRS moment I guess.

Terry,
click on the ServerSDX symbol in the taskbar to show the program
normally. Then choose the proper COM port in the setup window of ServerSDX.
I suppose you run your controller at a USB port (using a USB-to-Serial
adapter or cable with built in adapter). The port number of the
generated virtual COM port can change when you change the USB port.

expected on 31th July 2018.
OMOTENASHI, 6U CubeSat consists of Orbiting module and Surface probe.
Orbiting module and Surface probe will separate on the moon orbit and
Surface probe will land on the moon. Surface probe will observe
radiation and soil environment of the moon surface.
Orbiting module and Surface probe have UHF TX. Frequency has just

Message-ID: <68977F5EAC8A421BBE81D4124C9D9934@xxx>
Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at Scuola Secondaria di Primo Grado "Niccol? Pisano", Marina di
Pisa, Italy on 15 Dec. The event is scheduled to begin at approximately
12:31 UTC. It is recommended that you start listening approximately 10
minutes before this time. The duration of the contact is approximately 9
minutes and 30 seconds. The contact will be a telebridge between OR4ISS and
IK1SLD. The contact should be audible over Italy and adjacent areas.
Interested parties are invited to listen in on the 145.80 MHz downlink. The
contact is expected to be conducted in English.
Scuola Secondaria di Primo Grado "Niccol? Pisano"
The Scuola Secondaria di Primo Grado (Middle School) "Niccol? Pisano" in
Marina di Pisa (Pisa, Italy) consists of 3 sections (named A, B, C). Each
section consists of 3 classes (1st, 2nd, 3rd), corresponding to student ages
of 11 to 14. Each class consists of about 20 students. The school is part of
the Istituto Comprensivo "Niccol? Pisano", which also includes another
middle school in San Piero a Grado (Pisa, Italy), four primary schools (for
ages 6 to 10) and two childhood schools.
Participants will ask as many of the following questions as time allows:
1. What inspired you to become an astronaut?
2. Which is your favorite food on board?
3. Do you see more darkness up there than on Earth?
4. How can astronauts have a shower on board?
5. What will happen to your body if you don't exercise?
6. Which planets do you see from over there?
7. Can you hear sounds and noises outside the space ship?
8. Do you know how many space ships or satellites are there orbiting?
9. How many astronauts are there on board and how long must you stay on the
space ship?
10. What kind of machinery is on board? Which is the most important? Can you
describe it to us?
11. What are your astronaut suits made of? Are they heavy? Does someone help
you to put them on?
12. How much fuel does the space ship use?
13. Why did you decide to become an astronaut instead of, for example, an
astronomer, an engineer or an astrophysicist? What are your skills?
14. We know you can see 16 sunrises and 16 sunsets per day. So, have you
ever seen other celestial or terrestrial extraordinary events?
15. What are the main aims of your mission, what is your task?
16. Last year the ISS hosted the astronaut Scott Kelly. The press, on his
return, insisted very much on the effects illustrated by Einstein as
regards the paradox of the twins. Is it really possible to detect slight
differences at a biological level? Which examples can be given to
testify restricted or general relativity?
17. Why does the ISS have such a low orbit and it is not, for example,
geostationary? Does it lose height? Should it be re-lifted? If so, how
and to what extent?
18. In space, in conditions of microgravity, there is a loss of muscle and
bone mass, because of body statism. Is the regeneration of tissue in
space different in lack of gravity? Does microgravity influence also the
behaviour of electronic devices?
19. Astronauts are exposed to solar wind because they are outside the
shelter of the magnetic field. Which effects can be noticed in their bodies?
20. Would you be willing to leave on a mission to Mars, taking into account
the dangers that you might face while eventually trying to come back to
Earth? To what extent can your spirit of exploration go further?

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 Center for the Advancement of Science in
Space (CASIS) and National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,
teachers, parents, and communities learn about space, space technologies,
and amateur radio. For more
information, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,
David - AA4KN
