I would say to get on Twitter, but you need to stay on top of your feed. I don't get any political items in my feed, I only allow Ham items, and mostly Satellite. I can safely say that without Twitter I would not be where I am in my grid chase or my knowledge of operating sats. If you put post your pollical feelings I block you. If you cause drama, I block you. If you posting good clean fun items about Satellites, I will follow you. This process takes about 2-3 minutes a month and is time well spent.

The event is scheduled to begin on October 4 at 14:00 UTC for setup and operation and continue until October 8 ending at 19:15 UTC. Dates and times are subject to change due to ISS operational adjustments. (***) Images will be downlinked at 145.8 MHz +/- 3 KHz for Doppler shift and the expected SSTV mode of operation is PD 120. The main theme of this collection of images will be Satellites. Radio enthusiasts participating in the event can post and view images on the ARISS SSTV Gallery at https://www.spaceflightsoftware.com/ARISS_SSTV/. After your image is posted at the gallery, you can acquire a special award by linking to https://ariss.pzk.org.pl/sstv/and follow directions for submitting a digital copy of your received image. ************************************************************************************************************* There is a new radio on board the ISS. The Kenwood D710GA is now in use. The crossband repeater is now available when the radio is not being used for ARISS school contacts. The frequencies are 145.99 MHz up (67 tone) and 437.800 MHz down. Watch the Doppler on the downlink. ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. ************************************************* ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

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.

Re: [amsat-bb] Trouble with MMSSTV
by Steve Kristoff 07 Oct '20

07 Oct '20

Hope you don't mind that I shared your email (below) on-list, but I think you gave me a clue as to what I'm doing wrong and I would like folks to see a good example if they need it. Your screen shows the single peak at 1200, then essentially nothing until the picture info between 1500 and 2300 , then down to nothing again. I also noticed that the little green signal strength (?) bar just to the left of the FFT display is quite low. I think maybe I've just had the input level up too high. I've got signal in the FFT portion all the way from 1200 to past the 2300 and the green bar about 1/3 of the way up it's range. Would that be enough to throw off the sync? I may be able to clean up the signal just by turning down the volume. All helpful comments and suggestions are still very welcome. Steve AI9IN ----- Original Message ----- From: Greg D (ko6th.greg(a)gmail.com) Date: 10/07/20 13:54 To: Steve Kristoff (skristof(a)etczone.com) Subject: Re: [amsat-bb] Trouble with MMSSTV Hi Steve, The SSTV signals from the ISS yesterday were kind of garbled. Multiple stations reported this, so it's not your (or my) station's problem. Take a look at a video of a (good) pass on Monday last that I did for our club: https://www.youtube.com/watch?v=Z_SkJ8_mtA4 The FFT display should show the specific peaks in the signal around the line sync on the left, and a separate band for the actual picture to the right of it. If it looks like an amorphous blob, that was the interference we all heard. Hopefully they'll get it sorted out upstairs and we can grab a few more pictures today. Next pass in just under an hour here... Greg KO6TH

Trouble with MMSSTV
by Steve Kristoff 07 Oct '20

07 Oct '20

I've been trying to use MMSSTV to receive the ISS pics, but I'm having problems. I think the problem is with syncing. I can see that I am receiving strips of various colors, but they are not lined up to make a coherent picture. I downloaded the latest version of MMSSTV yesterday so that's up-to-date. I'm using SDR# to decode the signal from a dongle. The output of SDR# is to the input of VBCable and the input to MMSSTV is from the output of VBCable. Once I've downloaded the picture I can hit the "fix slant" and "fix sync" button and the picture straightens out some but still not enough to see the details. The op system is Windows 10. I've read through the MMSSTV help and can't find a fix.I must be missing a setting somewhere. If anyone has ideas to share on how to fix this, I'd appreciate your help! (Is there a better SSTV decode program?) Steve AI9IN
