Re: [amsat-bb] FoxTelem bug fix release 1.08y
by Chris Thompson 08 Feb '20

08 Feb '20

I'm not familiar with the program that is opening the archive. That seems to be the program throwing the error. If you unpack it at the command line does it work? The commands are: gunzip FoxTelem_1.08y_linux_tar.ga tar xvf FoxTelem_1.08y_linux.tar That should create a folder will all of the files in. Run those and let us know what error message they throw. The program you are running is almost certainly just running those commands for you. 73 Chris On Fri, Feb 7, 2020 at 5:15 PM David Padilla <subsitall2(a)yahoo.com> wrote: > Greetings.

HuskySat-1 in nasa.all has a space in its name
by Ronald Parsons 08 Feb '20

08 Feb '20

In today's nasa.all file, HuskySat's name has a space in it: "HuskySat 1" Spaces in satellite names can cause problems for some applications. nasa.bare has it correct: "HuskySat-1" Ron W5RKN

Message to US Educators Amateur Radio on the International Space Station Contact Opportunity Call for Proposals Upcoming Proposal Window is February 1, 2020 to March 31, 2020 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 is happy to announce a proposal window will open February 1, 2020 for contacts that would be held between January 1, 2021 and June 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 proposal window for contacts between January 1, 2021 and June 30, 2021 will open on February 1, 2020 and close on March 31, 2020. Proposal information and documents can be found at www.ariss.org. Two ARISS Introductory Webinar sessions will be held on November 7, 2019. The first is at 6:00 PM ET and the second is at 9:00 PM ET. The same material will be covered during both sessions, so choose the session that best fits your schedule. The Eventbrite link to sign up is https://ariss-introductory-webinar-fall-2019.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. More Information For 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. Please direct any questions to ariss.us.education(a)gmail.com. 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.

EM31/32
by Bob Liddy (K8BL) 07 Feb '20

07 Feb '20

Gridders, On my 1709Z pass today on AO-92 from the EM31/32 Line in LA, I logged the following Calls: K5DCC, K0TLG, N0JE, KI7UNJ, N3GS, WA5KBH, K9UO, W7JSD, K3RRR, AA6DY, KB6LTY, N8RO, N5UP, K7TAB On my 1745Z pass today on AO-91 from EM31/32 in LA, I logged the following Calls: WD9EWK, WA9JBQ, + 12 minutes of chaos!! In spite of it being an almost directly overhead pass at 1745Z, there was so much chaos and rude behavior that it was nearly impossible to complete a QSO. I've been operating Satellites since 1979 and I've never experienced anything like this. I can't even imagine what it must be like on weekends. My plan/hope was to do a lot of roving to adjacent Grids while here in EM32 until 3/5-ish, but I don't think I can tolerate such obnoxious activity. Perhaps, I'll only spend my time on the Linears. As long as I'm in the commenting mode, here are a few more. When it's busy and you are calling someone, use THEIR Call when you call them. Otherwise, no one knows your intention. When traffic is light, that's not much of an issue. Use Phonetics as much as possible, including saying individual numbers. Say 6-7 or 5-7 instead of 67 or 57 which sound almost exactly the same. Finally, for now, try not to jump into the middle of a QSO attempt before it completes. It eats up the short time available since they may have to try again and so will you. Next thing you know, the Satellite will be gone and nobody has made their contacts. If I botched your Call or missed it during my transcription, let me know and I'll re-check my recording. Will upload to LoTW soon. (No eQSL) 73, Bob K8BL (AMSAT #6593, since 1979)

HuskySat-1 Telemetry Doppler Adjust rate?
by Roy Dean 06 Feb '20

06 Feb '20

What are all all the computer controlled stations using for doppler adjust interval? I had previously tried 100ms, and was getting about 45 frames per decent pass. I just had a 50deg pass and increased the interval to 500ms, and got almost 70 frames. I wonder if there is a sweet spot? --Roy K3RLD
