Yes JO-97 has been sending its SSDV (Slow Scan Digital Video) since launch 24/7 and it seems its images it sends down gets updated every few months or so which is not very frequent. Unfortunately there has been no communication on what the status of the transponder it or if it will ever be activated. AO-73/EO-88 do not send down SSDV like JO-97 does. Also we haven't even gotten a telemetry format to even see the telemetry properly, if you look at the dashboard while decoding telemetry from JO-97 you will notice its all invalid/nonsense data. To my knowledge the dashboard does save in the images in the program somewhere, you will have to do some digging to find them (I think it saves to app data directory). 73 Nick KE8AKW

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. 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.

JY1SAT Images?
by Hasan al-Basri 15 Dec '19

15 Dec '19

All this time, I've been collecting and reporting telemetry from JY1 and I just noticed that it is also sending images (at least some times). Some info please: 1. Can the program be told to autosave images. (Looks like it does in AppData subdirectory) 2. Is JY1 always sending down image data? 3. Do either AO-73 or EO-88 do the same thing? I thought image was a special mode only turned on now and then. Perhaps that is true and I just got lucky bumbling around this morning! Tnx any info. 73, N0AN Hasan

Hi Peri, SatPC32 has to send the commands as required by the Yaesu GS-232 protocol. There is a single command that causes both rotors to run to the calculated target positions, the format is Waaa eee. 73s, Erich, DK1TB Am 14.12.2019 um 22:07 schrieb Peri Cosseboom AA7WB: > Hi, Attached is an email thread in which a problem affecting Satpc32 due to Yaesu changing the G5500' motors from AC to DC mid 2019 is discused.Satpc32 sends the A & E commands simultaneously. This worked with the old AC motors, it does not work now. I've asked Yaesu and EA4TX, Pablo to address the problem. They were uninterested. The emails were sent mid September. I've waited until now hoping that I wouldn't be the first to report this problem. I purchased Satpc32 from AMSAT of which I'm a member. I've yet to be able to use it.

I referred the problem to Yaesu but it is obvious to me that they don't have a g-5500DC in the shop so they can test for the problem in California.
