You aren't going to find any stations on L/V that aren't more active on
U/V. So you aren't going to work anyone new on L/V. The population of L/V
users seems to be a small fraction (less than 5%, possibly much less) of the
total population of U/V users.?And I don't think anyone finds L/V mode
easier to work than U/V mode.?
The only advantage to L/V is that you will have access to AO-92 (and some
future satellites like Fox-1C) during those 24-hour intervals once a week
(Saturday evening to Sunday evening) when L/V mode is active. I initially
got into L/V mode solely for this reason, although it did turn into a good
opportunity for me to do some experimentation with antennas and operating
ergonomics.?

Everyone:
A genuine newby to satellites, I plan to get QRV with U/V bands as soon as
I can (likely few months yet) due to difficulty procuring the orbital ring
rotors required to clear the trees at my QTH.
My goal is to work as many DXCCs over time as possible (and probably WAS
too).? Given this goal, is L-band helpful (will there be even 1 or more
new DXCC QRV on L-band that is easier or not workable on U/V) vs.
conventional U/V bands or should I stick with U/V given my
interests/goals?
Thank you 73,

Graham,
Thanks for keeping us posted. Really appreciated.
Will continue to upload the Rx data to the data warehouse when possible
(same as for other many birds).
As always, the birds signals quite strong and reliable TLM received this side.

Does anyone know if the radio configuration of voice and packet are
still mutually exclusive? I.e., if you are hearing packet on 145.825,
you will know not to bother listening for voice on 145.800?

International Space Station Astronauts are Calling CQ ARISS Students
??? ARISS-US program?s education proposal window open Oct. 1 - Nov. 30, 2018
?
September 25, 2018:? ARISS is seeking proposals beginning October 1, 2018
from US schools, museums, science centers and community youth organizations
(working individually or together) to host amateur radio contacts with an
orbiting crew member aboard the International Space Station (ISS) between
July 1 and December 30, 2019.
?
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. ARISS has been pleased
of late, to be one of many possibilities of interest to educators during
NASA?s A Year of Education on Station, which celebrates an almost 12-month
presence of a teacher aboard the ISS.? 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 October 1, 2018 and the proposal deadline is
November 30, 2018.
For proposal guidelines and forms and more details, visit:
http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html
?
Proposal webinars for guidance and getting questions answered will be
offered October 11 and October 23, 2018, both at 8 pm Eastern Time. Advance
registration is necessary. To sign up, go to:
ariss-proposal-webinar-fall-2018.eventbrite.com/

Graham,
Hope you don't mind that I copied your post to my club's website. We have
a (growing) number of satellite operators, and I passed the news to them
about AO-73 going off amateur mode a few weeks ago. We will be having a
special event station at a hamfest this weekend, and it's great to know
there are a few additional satellites available!

Hi Ron,
I'm using a Comet 18 el yagi.? Signals do fade and circular polarisation
would be an advantage.
As for power you don't need much.? I use 5W without any problems.

If they are using the D710 in the sevice module for voice the packet on the

Subject: [amsat-bb] Upcoming ARISS contact with Ashford School,
Ashford, CT
Message-ID: <F1014E1FCEFC4D40873D115FEECBA025@???>

An International Space Station school contact has been planned with
participants at Ashford School, Ashford, CT on 10 Oct. The event is
scheduled to begin at approximately 18:39 UTC. The duration of the contact
is approximately 9 minutes and 30 seconds. The contact will be direct
between NA1SS and KZ1M. The contact should be audible over the state of
Connecticut 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.
Students at Ashford School are busy learning about Space in preparation for
their ARISS contact. The sixth graders made model rockets while learning
about force, the elementary students are coding robots on a Giant Mars Map
(thanks to the Share Space Foundation), middle school students are creating
robotic arms that can take simulated rock samples, and all the students will
get to build an FM radio with snap circuits to learn more about how radios
work.
Participants will ask as many of the following questions as time allows:
1. Do you wear sunscreen on the International Space Station?
2. Do butterflies just float on the International Space Station or do they
use their wings to fly?
4. What is strangest thing you have ever seen in Space?
5. How do you protect yourself from meteors on the International Space
Station?
6. What food is the most fun or the messiest to eat in Space?
7. What inspired you to become an astronaut and who do you look up to?
8. What is the hardest thing about having zero gravity?
9. If someone becomes sick, then what do you do?
10. Have you ever been in an emergency situation on the ISS and what was the
solution to that problem?
11. What powers rockets?
12. Do you think humans will go to Mars?
13. How long before we go to Mars?
14. What kinds of technology do you use on the Space Station?
15. What does it feel like emotionally to be in Space, and to see the world
from such a unique perspective?
16. How many flips have you done in a row?
17. Can you get dizzy in Space?

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 informa
tion, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,
David - AA4KN

Olde Antenna Lab makes a "wheel" style omni for this uplink.? I have one
mounted and fed with 7/8" hardline but have not had a chance to wire in
my 80W amp to give it a try.? I don't think Dave, W6OAL, has put it on
his web site yet so you will have to give him a phone call.
