> > These antennas will have no metal parts except the active elements and the purpose is to be prepared or the future Lunar and eventually Mars repeaters, but also for own experimentation. > > How would a mars repeater work, being that the closest it will ever be is 3 minutes away by way of light speed (each way)? Everybody is a lid when nobody can hear themselves on the downlink. Not sure even a store and forward system would work. And that's even IF we can build a yagi thats short enough to fit in our sub-acre plots (and has enough gain). :D --Roy K3RLD

Gridders, Thanks for all the SO50 & RS44 Q's today from EM21/31. However, I had mic trbl during the CAS4B pass and I only recorded a lot of static covering much of the Calls. Send me an email and I'll compare to what I have so I can log you properly. K8BL(a)ARRL.NET. TNX/73, Bob K8BL

The main page for Applying to Host a Scheduled Contact may be found at https://www.ariss.org/apply-to-host-an-ariss-contact.html +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ARISS Contact Applications (United States) The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between July 1, 2021 and December 30, 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is November 24th, 2020. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-fall-2020.eventbrite.com The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio. Please direct any questions to ariss.us.education(a)gmail.com. For future proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org. 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 ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ARISS Contact Applications (Europe, Africa and the Middle East) Schools and Youth organizations in Europe, Africa and the Middle East interested in setting up an ARISS radio contact with an astronaut on board the International Space Station are invited to submit an application from September to October and from February to April. Please refer to details and the application form at www.ariss-eu.org/school-contacts. Applications should be addressed by email to: school.selection.manager(a)ariss-eu.org ARISS Contact Applications (Canada, Central and South America, Asia and Australia and Russia) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Organizations outside the United States can apply for an ARISS contact by filling out an application.

Doppler Not Correcting
by crohtun＠aol.com 25 Nov '20

25 Nov '20

I have followed Erich’s procedure for setting the Doppler correction again and again but still can’t get CAS-4B to be stable. It is only that one satellite that’s a problem. My transmitted signal wanders from one end of the passband to another. If corrected using uplink calibration buttons at TCA and saved, it will all be wrong the next pass. ...???

Re: [amsat-bb] Fiberglass Cross-boom Alternative?
by MICHAEL WILLIAMS 24 Nov '20

24 Nov '20

My first cross boom was a clothes closet rod from Home Depot or Lowes. Being very strong, it was a good substitute. It supported a 14 element KLM for 2 meters on one end and a 11 turn helix (70cm) on the other. I gave it a coat of paint and used it for many years. GL, Mike, K9QHO
