Newbie Questions - ISS
by Jackie Dander 14 Feb '20

14 Feb '20

1. Is this the best way or place to post such questions? 2. I have studied past posts and other sources but can't find answers to questions below. 3. I am trying to listen to ISS. N2Y0 and HeavensAbove list the same pass for my location today (FM14be, 16:39 local time, elevation 56 degrees) but AMSAT predictor says 4 degrees for that pass. Why the difference? 4. N2Y0 says up/down is 437.550/437.550, ASFK, inactive. HeavensAbove says 145.825/447.550 FM active. Who is right? How can I get correct frequencies to listen to? thanks Isaac

Re: [amsat-bb] Leo Bodnar ICOM IC-9700 Reference Injection Board
by Mark L. Hammond 14 Feb '20

Hi Bob, I have this setup. It works great--and in fact so well, it's hard to see! The "setup" didn't do anything for me unless I ran the numbers WAY off to one side or another. Then the radio acted weird--it was effectively messing up the proper oscillator freq. and sounded warbled. I've put coarse and fine in the middle of the recommended ranges and leave them there...the "tuning" is broad. Don't fret over adjusting uch here... How can you see it working? Here's what I did--use the waterfall to watch a stable, steady signal (even a "Birdy") on 2M, on SSB. Zoom in the waterfall, so it's like +/- 2 kHz. Now, using the software for the freq. standard, toggle the reference signal ON and OFF, slowly....you should be able to see the "birdy" move just a little, back and forth as you toggle off and on. With the freq. standard "on", it's in the right calibrated place. With it OFF, it's showing you how far off freq. your radio is without correction. Hope that's clear! I spent some time convincing myself it was working--and did what I tried to explain above. check it out, let me know how you make out. 73, Mark N8MH At 06:03 AM 2/14/2020 -0800, Bob Hammond via AMSAT-BB wrote: >Anyone in the US use this board (along with a GPSDO) in their 9700? > >http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=… > >How do you know it's actually working?

SDR Recommendations
by Mike Lucas 13 Feb '20

13 Feb '20

I'm thinking of acquiring an SDR unit for the station for downloading sat telemetry etc. I'm new to the SDR world but learning. I'm currently using a Yaseu 736R which has served me well. Not sure how you configure SDR for Doppler tracking etc. so looking for links to info I can educate myself on what all I need etc. Are there any particular SDR radios that lend themselves best for satellite work more than others? The SDR Play boxes look solid, are they recommended? Regards, Mike N7ASZ

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.
