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.

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

Unusual ISS SSTV signal
by Loren M. Lang 06 Oct '20

06 Oct '20

During one of the SSTV transmissions today, I heard an unusual signal overlaid on top of the regular SSTV signal. It started just after the original SSTV signal, and was initially quite strong, but eventually lost out to the regular SSTV signal. It sounds similar to SSTV, but not quite the same. This started at 2020-10-06 02:54:32Z. You can hear it here: https://www.dropbox.com/s/abcizkoly8rn1ij/funny-sstv-signal.mp3?dl=0 You can see the waterfall during the initial decode here: https://www.dropbox.com/s/dxmy4rhruiit84v/funny-sstv-signal.png?dl=0 It does look like a separate signal on top of the original SSTV signal and it looks more centered on 145.800 MHz than the Doppler shifted ISS transmission which makes me thing it might be terrestrial, but I have no idea where it would be coming from. It definitely looks like it was targeting 145.8 and it sounds SSTV-like. The signal poped in several more times as can be seen in this waterfall: https://www.dropbox.com/s/gwh4h4b1d8qtnbv/funny-sstv-signal2.png?dl=0 Any ideas what this came from? Here's the image I received during that pass: https://www.dropbox.com/s/j11wj6yo9s2ceg9/sstv-202010060311.png?dl=0 I do have the raw baseband signal if anyone's interested. -Loren K7IW

Re: [amsat-bb] Fox Telemetry antenna?
by Kevin 06 Oct '20

Steve, I run the same antennas here, maybe something I do to my rotors make a difference. I clean and grease them with a marine grease, the old wire on the slider style pots have been replaced with the newer style closed back ones, I added thermal switches to the inside of the motors so if something snags they shutoff rather than burn up, an interesting note is that it looks like Yaesu had planned for a cutout as the pc board inside the motor has a spot where you move one wire and then there are two holes that line up perfectly with a spot to slip the cutout into the motor and solder to the board, I also Loctite the drive screws. For me when they do finally fail it is the pot that gets erratic, a new pot and re-grease and away they go. If yours were dying every 4-8 months I can see where spending the bucks for the Spid makes perfect sense, It's also possible you guys track way more sats than I do, with AO-92 going dark I only track 4 sats on a daily basis now. 73, Kevin WA7FWF On 10/6/2020 1:29 PM, Stephen E.

Since he is a dedicated telemetry collector like you, and since he is a control operator for the Fox satellites, he replaces his rotors when they fail. He had a volunteer to repair his broken rotors, so I transported 6-8 rotors from his garage in North Carolina (not near salt water either) to Indiana.

You can buy the AlphaSpid rotors without the controller (my recommendation for heavy duty use) and use a Green Heron instead. > > Still: YMMV > > 73, Steve N9IP

Fox Telemetry antenna?
by Bob Hammond 06 Oct '20

06 Oct '20

I'm going to get set up to monitor Fox telemetry. For those of you who already do so, what antenna are you using? I'm set up with 2M, 70cm, and 23cm CP antennas on a G5500 rotator but I understand I can also use a fixed antenna such as a Lindenblad or quadrifilar. Suggestions? Bob W7OTJ

Fox Telemetry antenna?
by Stephen DeVience 06 Oct '20

06 Oct '20

During my time in Chicago, I collected telemetry with a QFH (no preamp) that was actually designed for the NOAA satellites. It did an OK job but wasn't going to put me on top of the leaderboard. A Lindenblad would probably be better for the lower passes. You could probably make a phased array of either type if you wanted. -Stephen N8URE

I've been using a 3/4 wavelength ground plane (vertical with 4 equal length radials) in my attic for the last couple of years, and have usually been in the top 60 on the leaderboard for the fox satellites. Lately I've been having FoxTelem stability issues, though (pretty regularly getting a usb access error). --Roy K3RLD > I'm set up with 2M, 70cm, and 23cm CP antennas on a G5500 rotator but I > understand I can also use a fixed antenna such as a Lindenblad or > quadrifilar.

I also noticed a lot of fading. I heard you and KB2M but not very clearly. I made a QSO with KI5DVX near the end of the pass, but it was rough going. Maybe the satellite antenna was just in a bad orientation this morning. -Stephen N8URE

ARISS News Release No. 20-19 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org FORIMMEDIATE RELEASE ARISSContact is Scheduled with McConnell Middle School, Loganville, GA October06, 2020—Amateur Radio on the International Space Station (ARISS) has receivedschedule confirmation for an ARISS radio contact with astronauts. ARISS is thegroup that puts together special amateur radio contacts between students aroundthe globe and crew members with ham radio licenses on the International Space Station (ISS). This will be a Multipoint Telebridge Contact via Amateur Radio between the ISS and students fromMcConnell Middle School in Loganville, Georgia. Students will take turns askingtheir questions of ISS Commander Chris Cassidy, amateur radio call sign KF5KDR,during the ARISS radio contact. The downlink frequency for this contact is 437.525 MHz. ARISS team member Jan Poppeliers, using call signON4ISS (from an AMSAT amateur radio clubstation in Aartselaar, Belgium), will serve as therelay amateur radio station. Each student asking a question of Cassidy on the ARISS radiowill be teleconferenced in from home or social-distancedat school. Youth and faculty and the publiccan watch the livestreamed action from home. TheARISS radio contact is scheduled for October 7, 2020 at 10:18 am EDT (Georgia) (14:18UTC, 9:18 am CDT, 8:18 am MDT, 07:18 am PDT). McConnellMiddle School (about 2,300students ages 11 to 15) is a Gwinnett County public school near Atlanta.The district’s career-planningcurriculum group integrated lessons into established science, math and languagearts classes before the contact in order to increase student interest andawareness related to space science, expand student experience with researchmethodologies, and inspire them to pursue studies and careers inscience-related fields. The school’s McConnell Radio Club, in its 6th year,is mentored by members of the Gwinnett Amateur Radio Society who provide radioclasses and equipment for student use, and guided the ARISS project, a part of thefaculty’s efforts toward becoming a STEM-certified school. ARISS invites the public to view thelivestream of the upcoming ARISS radio contact at: https://youtu.be/pHOM15BLRSo. _______________________________ Astime allows, students will ask these questions: 1. Are there specialactivities designed for you to help relieve the stress of living and working inspace? 2. Describe whatsurprised you about earth when you got to the ISS. 3. Do you seeevidence of the recent West Coast wildfires or other environmental situations? 4. As a middle schoolstudent what can we do to prepare ourselves for the job you do today as anastronaut? 5. In the movie TheMartian, Mark was trained as a botanist. What is your area of interest and whatexperiments are you doing in your field? 6. How long is yourmission and how do you expect it might impact your body? 7. What was thehardest part of training prior to going to space? 8. How often do youneed to do repairs on the outside of the ISS? 9. Describe yourmedical training that would help if an astronaut becomes ill or seriouslyinjured while on the space station. 10. Standard airpressure on earth is 1 atmosphere. What air pressure do they try to maintain onthe ISS? 11. Whatqualifications do you have that enable you to be assigned to more than onemission or similar? 12. Have you evertried growing carrots or root vegetables in space? 13. Are there anytimes where any shipments of food or drinks are running late, or have spaceflight troubles, and you run out of food or water for the time? 14. How does foodtaste when you don't get to smell it? 15. How is the ISSdesigned in case of a collision with space junk or a meteoroid? 16. What is theprocedure if spills, liquid or solid, occur during experiments? 17. How do youmaintain clean hygiene while in space? 18. What is yournormal schedule on the ISS?
