NO84 in safe mode

Hi Bob, Just listened to the 03:05 UTC NO-84 pass on 6-12-19. Glad to report the PSK31 transponder is acting normally again! Had a quick qso with Scott K4KDR and it sounded like its usual self again. Also heard many beacons on 145.825 and looks like most of them were picked up by the igate on findu. Glad to see NO-84 back to its somewhat usual self again. Im sure it will be a valuable asset to use on field day also. 73 - Nick KE8AKW

Upcoming ARISS contact with Peninsula Grammar, Melbourne, Australia
by n4csitwo＠bellsouth.net 12 Jun '19

12 Jun '19

An International Space Station school contact has been planned with participants at Peninsula Grammar, Melbourne, Australia on 13 June. The event is scheduled to begin at approximately 11:10 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and VK4KHZ. The contact should be audible over portions of Australia and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Peninsula Grammar is a day and boarding school for approximately 1400 students from three-year-old Kindergarten to Year 12. At Peninsula Grammar we see learning not just as a path to university and a career, but also as a path to wellbeing. The books we read, the science we absorb, the languages we learn, the artistic, sporting and musical skills we acquire are the tools that enable us to fulfil our potential. Participants will ask as many of the following questions as time allows: 1. Although you are in quarantine before going to space, if someone was to get sick or injured in space, is there always a qualified first aid person when it happens? 2. How long will it take to recover and will you miss the space station when you come down? 3. What is your favourite thing to do in space? 4. What was your first thought during lift off when you travelled to the space station? 5. What kind of science experiments are you doing? 6. Why did you choose to be an astronaut? 7. How do you use the Internet on board the space station? 8. When you were first selected to go to the ISS in 2013, were you thinking about how much your research might affect the future on Earth and did that help you cope with leaving your family behind, getting into a space craft with people you don't really know and possibly risking your life? 9. What training did you do to become an astronaut? 10. Have you ever had a major issue with any of the technology on board the space station? 11. What is currently being done to try to help your life in space become easier? 12. How has your understanding of the universe changed now that you have seen it from space? 13. What do you miss most about Earth? 14. Can you have baths or showers in space? 15. Did the air force help you with what you are doing in space now?

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 (STEM) 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.

Launch weight (mass) of Phase 3-E (Express)?
by Nicholas Mahr KE8AKW 11 Jun '19

11 Jun '19

Hi Greg, That is hard to say exactly for sure as it actually has not been done yet. Maybe somebody else out there knows? I do know AO-10/13 was around 140kg at launch with fuel and is 90kg without fuel. So it would be significantly less as the fuel does weigh a lot (50kg?). Also a quick search shows that a 400N motor weights around 9.5 pounds, so minus that.Unfortunately that launch opportunity for the direct launch to a Molniya type orbit was scrapped. Hopefully AMSAT find some sort of a affordable launch opportunity for it here soon in the up coming years. It is difficult enough now a days just to get a 1-2kg cubesat into LEO unfortunately. 73 - Nick KE8AKW

I understand that the Phase 3E spacecraft frame is currently in Germany (AMSAT-DL). https://amsat-dl.org/en/amsat-phase-3-e-express/ What was the planned launch weight of P-3E? (preferably weight without 400N kick motor). greg w9gb Sent from iPad Air

NO84 in safe mode
by Nicholas Mahr KE8AKW 11 Jun '19

11 Jun '19

Hi Bob, Yes me and Scott K4KDR has observed this both with NO-84 the past few days. Here is a video Scott has on youtube of NO-84's 70cm PSK31 downlink acting crazy https://www.youtube.com/watch?v=8XqcUNJumSE . The 70cm downlink has been either a ticking carrier, not transmitting at all, or will transmit properly for a few seconds before going crazy again. I hope this is not the last we hear of the PSK31 transponder as I have really enjoyed it. The APRS downlink with the beacon telemetry has been observed by both me and him as either off completely or on for a limited a time. I hope to see NO-84's condition improve soon and to see the launch coming up in a few weeks of NO-84s replacement, PSAT-2 on the next Falcon Heavy Launch! 73 - Nick KE8AKW

OUTERnet becomes OTHERnet (APRS geo feed)
by Robert Bruninga 11 Jun '19

11 Jun '19

Since about 2 years ago, the APRS satellite ground station captures have been made available worldwide via three GEO satellites for reception anywhere on earth. But I recently found that the OUTERnet system has changed to a new GEO satellite constellation and no longer uses INMARSAT L band satellites but is now using a KA band downlink over the USA. And that they are now selling a new receiver kit for this satellite. Has anyone kept up with them? Here is my original WEB page but with the links changed from OUTnet to OTHERnet: http://aprs.org/othernet.html If anyone has one of their receivers or is receiving the downlink and/or wants to help me get my web page all cleaned up to what has changed over the last two years, let me know. This is a powerful capability. I hope we can keep it working. Bob, Wb4APR
