Upcoming ARISS Contact Schedule as of 2020-10-09 15:30 UTC Quick list of scheduled contacts and events: ABOUT GAGARIN FROM SPACE Conducting an amateur radio session with October 9 (World Post Day) schoolchildren of Vladivostok, Vladivostok, Russia, direct via RMØM (***) The ISS callsign is presently scheduled to be RSØISS The scheduled astronaut is Anatoli Ivanishin Contact was successful Fri 2020-10-09 08:15 UTC (***) Ramona Lutheran School, Ramona, CA, direct via N6ROR The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Chris Cassidy KF5KDR Contact is go for: Wed 2020-10-14 16:26:13 UTC 43 deg ************************************************************************************************************* 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. The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools The ARISS webpage is at https://www.ariss.org/ Watch for future COVID-19 related announcements here also.

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.

As another hurricane approaches the gulf coast with the potential to knock out power to tens of thousands, I was pleased to see that CQ published my article this month (Oct) on using an EV or plugin Hybrid for emergency power for days or weeks. With the 10 to 100 kWh batteries in EV's and the 50kW or so generators in hybrids, your car makes a great accessory for your house when the grid goes down.

Since this was after the Japanese 2011 T?hoku earthquake and tsunami, I assume the OEM suppliers to Yaesu were lost. This is a Photo of the LAST OEM switch, from Yaesu USA Parts (before 2011), now discontinued. Photos at entry #8 (QRZ Q&A Tech Forums). LOOK at photo carefully. https://forums.qrz.com/index.php?threads/g-500a-replacement-switch.664784/ The Kenpro/Yaesu used an OFFSET Lever (Pivot) on that Rocker switch mechanism. The Paddle Lever is NOT Symmetrical about the pivot axis. Kenpro designed their front panel molds (plastic injection) of the rotator controllers to work with that specific Offset Lever style. ? The old Japanese OEM switch used rivets (thru metal pin), while the NKK levers use an outside edge plastic mobs to fit into holes on the variety of paddle/rocker options. There is not a thru pin on the NKK. == In 2014, I ordered the NNK Series M2 rocker switch parts (substitute candidate) from Mouser, when Mouser stocked NKK # M202TYW01 . ($4.80 in 2014). This part was correct size for Kenpro/Yaesu G500/G550 controllers and accepts a variety of ?Paddle? styles https://www.mouser.com/ProductDetail/633-M2022TYW01 This NKK rocker switch properly fits the Kenpro/Yaesu front panels (rotator control). https://www.mouser.com/datasheet/2/295/MrockersFlatFrame-1663268.pdf HOWEVER, the standard NKK Levers (Paddles) are SYMMETRICAL. They do NOT have the proper OFFSET. NKK # AT4157C (Red) https://www.mouser.com/ProductDetail/633-AT4157C NKK # AT4157A (Black) https://www.mouser.com/ProductDetail/633-AT4157A NKK Switch Accessories https://www.mouser.com/datasheet/2/295/accessorieshardware-10910.pdf === SOLUTION ?? Someone (AMSAT member?) to design a proper ?Offset? Paddle (asymmetrical) for the standard Rocker switch mechanisms (NKK, C&K) that fit Kenpro/Yaesu rotator controllers. The Design (CAD) could then be 3D-Printed OR Injected Molded (Plastic). greg, w9gb elmhurst, IL == Date: Thu, 8 Oct 2020 12:13:19 +0000 From: "Stephen E.

It was long enough that I was able to coach a few folks who had problems one day, have a success the next. Also thank you for including English subtitles to the predominantly Russian images, and Spanish for the one I saw regarding Equador's nanosat. But a request... Is there a better font which could be used for future events? I noted several folks here who were able to grab an image, but couldn't read any of it, not even the part in their own native language. A sans-serif font would be a good starter, perhaps one with skinnier lines (less bold) would help too. Any text at this resolution is hard, and I'd rather pick a more friendly font than try to increase the size for readability. Pictures are more pleasing than text. To the general population, is there a "best" font that can be recommended for the text used for Latin-based languages at this resolution, and with this sort of "propagation"?

My recommendation is to follow AMSAT (the organization) tweets only.? Even tweets from individuals that are of satellite ops interest get retweeted by AMSAT, so it's a simple way to get what you might be looking for without following a clutter of tweeters.? They even retweet me if I tweet something about Engineering that is intelligent and useful information.? There is an audience looking for AMSAT information via Twitter, so I'm glad to share news on their preferred platform.? It would be foolish not to do so and somewhat un-hamlike, given that we're building stuff that is/will be available for satellite users worldwide.? That's why I started using Twitter. There are other worthy organizations, corporations, and government agencies to follow too for your space (and other) interests that are about news and information and not random nonsense.? I follow various NASA branches, and other space/satellite related stuff like Spaceflight, SpaceX, Virgin Orbit to name a few, the corporations/agencies/organizations that are AMSAT "job" related as well as related space hobby interests.? I follow only a handful individuals, some who are AMSAT officers and a few friends/acquaintances who know how to tweet useful or interesting info and then be quiet again, for a spell.? And let me add AMSAT-UK as a suggestion, they share in a way similar to what AMSAT does here with useful info as it comes up.? Give Twitter a try, I'd say it's worth a look.? You can ease in and add more over time.? I'd also suggest that you don't jump in and follow a bunch right off because it might be information overload rather than informative. And if you don't like it you can blame me, in a Tweet!? I'm a popular "public figure" for that type of stuff.? Then just close your Twitter account, and move on...

SSTV-friendly fonts
by Greg D 09 Oct '20

09 Oct '20

Hi folks, but mostly the ARISS team, First, thank you for hosting the extended SSTV event on the ISS. It was long enough that I was able to coach a few folks who had problems one day, have a success the next. Also thank you for including English subtitles to the predominantly Russian images, and Spanish for the one I saw regarding Equador's nanosat. But a request... Is there a better font which could be used for future events? I noted several folks here who were able to grab an image, but couldn't read any of it, not even the part in their own native language. A sans-serif font would be a good starter, perhaps one with skinnier lines (less bold) would help too. Any text at this resolution is hard, and I'd rather pick a more friendly font than try to increase the size for readability. Pictures are more pleasing than text. To the general population, is there a "best" font that can be recommended for the text used for Latin-based languages at this resolution, and with this sort of "propagation"? Greg KO6TH

NA1SS is Very Popular Today
by Robert MacHale 08 Oct '20

Looks like over half the APRSAT traffic in the past 24 hours involved NA1SS. Kudos to Frank Bauer and ARISS for the new equipment. Kudos to Robert Bruninga for creating a useful protocol.

We then had to go to get some dinner and now I am set up for the 1929 pass, EU and maybe JA this pass, I will try to stay up as long as possible before I drive down to the hotel to get some sleep. My priority will be NA and JA. the 2100 utc and the2300 utc passes should be OK for east NA. I will work SSB tonight around 435660 downlink. Adrian VA3NNA

Fwd: Coming Hurricane and power outages
by Robert Bruninga 08 Oct '20

08 Oct '20

For continuity of radio operations... As another hurricane approaches the gulf coast with the potential to knock out power to tens of thousands, I was pleased to see that CQ published my article this month (Oct) on using an EV or plugin Hybrid for emergency power for days or weeks. With the 10 to 100 kWh batteries in EV's and the 50kW or so generators in hybrids, your car makes a great accessory for your house when the grid goes down. The article is just a short condensation of some of the Emergency Power topic that is in the ARRL Energy Choices handbook I also posted greater detail from the article on this page: http://aprs.org/FrankenVolt.html Bob, WB4APR Author http://aprs.org/Energy-Choices.html

Got a note from Halvard, LA7XK, this morning. His plane was turned back yesterday due to fog at the airport in Longyearbyen. He's currently in Northern Norway waiting for conditions to clear. When I get an update, I'll post it here. Adrian VA3NNA
