FUNcube Data Warehouse Operational
by David Johnson 20 Jan '23

20 Jan '23

Hi, We are pleased to announce that FUNcube1 data is being successfully processed again. We had a roll-over of a counter on board that caused processing of a data element in the warehouse to be disrupted. The realtime data is being displayed, the fitter messages and WOD will take a few orbits to be displayed. Thank you all again for you patience and the continuing uploads, upload scores are not affected and will continue to count from the failure. 73 Dave, G4DPZ On behalf of the FUNcube Team

Thanks for the report. I expect we have at least another 12-24 hours of battery if we are lucky. So keep listening! Also note the info in the telemetry. I last uploaded the satellite OS over one year ago, as the “375” days of uptime states. Also note the clock on FS-3 runs “fast” and gains time. So be sure to note local host time when copied. 73, Mark N8MH On Fri, Jan 20, 2023 at 5:30 AM Apostolos Kefalas via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > Hello, > > One packet received during a 2 degree pass this morning > > > PFS3-1>TIME-1:PHT: uptime is 375/18:09:33.

If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## 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. Watch for future COVID-19 related announcements at https://www.ariss.org/ The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools **************************************************************************************************************************************** Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-01-19 19:30 UTC.

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.

Hi all, Current predictions for Falconsat-3 reentry seem to converge around late (UTC) 21 Jan 2023 to early (UTC) 22 Jan 2023. Therefore, I plan to command TX ON about 1910 UTC today, 19 Jan 2023, with battery management OFF. In recent weeks, it has survived this for 24-30 hours--at which time I have turned it OFF. So, this will be right on the margins for battery vs. reentry, but we're going to "flame out" either way :) Good luck with listening over the next couple of days..

Re: Falconsat-3, the end is near! TX to be turned ON 1910 UTC 19 Jan 2023

Mark, Thanks for the infos. On my side I am already on a 24/7 watch for F3 re-entry. For all, I wish also to confirm that the Mauritius Amateur Radio Society (MARS) will issue a special Award for the last formal (AMSAT Leaderboard/Satnogs) reported signals from F3, additionally a MO-112 postal first day cover will be sent to the winner with the certificate. The purpose is to encourage all to get the maximum of information and try to locate the approximate re-entry location of F3 and compare same with calculated one. Good luck to all with F3 last signals. Jean Marc (3B8DU) > On Jan 19, 2023, at 4:01 PM, Mark L.

Re: Yaesu 5400b azimuth pot

Replace the small wire and it > will work another 10 years or so. Thanks to everyone for advice on the azimuth pot, I'll give Yaesu parts a call and cross my fingers. Amazing the rotor worked this long with no problems or maintenance. Has anyone found a video on the web of disassembly and re-assembly of the rotor, with important points to be aware of? I only want to disassemble just enough to work on the pot and its connecting wires. From my testing I'm sure it's a combination of bad pot and connecting wires. Issue only manifests itself from around 300 to 0 degrees azimuth with it occurring at different spots in that location depending on whether it's rotating clockwise or counter clockwise . The ohms reading across pins one and three drops from 500 ohms to around 200 ohms or less. Testing resistance between pins 1 and 2 when rotating, smooth 0 to 500 ohms, Between pins 2 and 3 when rotating is where I get the resistance hiccup. It won't keep me off the birds, but I'll mainly only be able to do satellite passes that are east of me until fixed. KB7ADL
