I was one of those kids, too, though from a more remote perspective
here in Canada. The early space program was one reason I studied
engineering in university. I wanted to do that stuff myself.

An International Space Station school contact has been planned with
participants at World Genesis Foundation (WGF), Goodyear AZ on 11 Jan. The
event is scheduled to begin at approximately 16:10 UTC. The duration of the
contact is approximately 9 minutes and 30 seconds. The contact will be
direct between NA1SS and W6FOG. The contact should be audible over the
state of Arizona 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.
There are two non-profit organizations based in Quartzsite, Arizona,
coordinating this ARISS contact. The World Genesis Foundation operates with
a mission to "leave no child without hope for the future." Quartzsite in
Motion is a public/private partnership with the town of Quartzsite that
operates to "promote health, education and community' in Quartzsite and
surrounding towns. Students participating in the event come from six small
schools in five town towns in rural western Arizona.
The coordinating organizations have provided training and support materials
to administrators and teachers at every participating school. The contact
is part of a year-long program designed to encourage students to study and
pursue work in science, technology, engineering and math.
Participants will ask as many of the following questions as time allows:
1. What is the most unusual thing you have seen in space?
2. Did you want to be an astronaut as a kid?
3. What is it like with no gravity?
4. Can a person be in space too long?
5. What are your favorite science experiments that you have been a part of
in space?
6. What do you do when you are not in space?
7. What kinds of hazards are you exposed to in space?
8. How has Robotics played a role with the ISS?
9. Can you share a story that sticks out in your mind since becoming an
astronaut?
10. Are you able to grow plants in the ISS?
11. Has your understanding of the universe changed since seeing it from
space?
12. What kind of games or things do you do for entertainment there?
13. What are the effects of weightlessness on your body or mental state?
14. What has been one thing you have learned from your studies there that
surprised you?
15. Is there one thing that your training has not prepared you for?
16. What have been your missions outside the Space Station?
17. Have you used 3-D printing on the ISS?
18. What's your advice to young people dreaming of becoming involved in
NASA's space program?

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,

FYI - The XP20s can easily be configured for RHCP by using a power splitter
and feeding the V-pol and H-pol on a single boom with the 3db split
signal. The V-pol and H-pol elements on the XP20s are staggered by 1/4 WL
so a CP wave front will be generated for null free sat work.
The XP20 is a great antenna. With fancy switching, you can have V / H / CP.
2 x XP20s and 1kw makes a very capable 2M EME setup.
I'm just sayin'

Hi everyone.
I suppose that any deviation from the ideal setup of a near-perfectly
matched antenna & receiver will have SOME negative effect, but for a
receive-only antenna, how badly am I hurting myself to split the antenna
between two receivers?
Since frequency is probably important to answer this, I?m referring to 70cm.
Also, if it matters, I have a very good preamp (SP-70 from SSB) at the
antenna feeding 25 meters of LMR-400. Both receivers are SDR devices
(receive-only).
When I tested against a 70cm beacon, there was some small reduction in
signal strength but it wasn?t much. With voice, you might not notice but my
interest is telemetry data.
Thanks for any recommendations or experiences with a similar arrangement!

Many thanks to Bruce KK5DO, Glenn AA5PK and Erich DK1TB for your
assistance in getting SatPC32 set up with my two FT-817s. I'm looking
forward to continuing and seeing how they work together!
73 and thanks again!

Hi Guys, thank all your company on the satellites, in my last trip I made
163 contacts, activate grids DK97, DK98, DK87, DK88, EK06, EK07, EK15,
EK16, EK25 and EK26.
Now I can say that I have worked from 35 grids rare, XE in Mexico as
station "Rover". We will look for other new adventures, and return to the
previous ones for those who could not work on this trip.
Thanks also to Doug N6UA, the donation of a battery for my Handy FT-60R, to
be like my sponsor.
All records are in Lotw now.
Until the next trip ...
David Maciel XE3DX
