SSTV EVENT ARISS 40th Anniversary event starting Dec 16
by christy 15 Dec '23

15 Dec '23

to All, https://ariss-sstv.blogspot.com/ ARISS is celebrating 40 years of human tended operations from space. STS-9 was the first time amateur radio was operated by a person while on orbit back in late 1983. To commemorate that beginning, an SSTV activity has been scheduled to start on Dec 16 about 10:15 UTC and run until December 19 around 18:00 UTC. Operations will be on the standard 145.800 MHz downlink using SSTV mode PD120. Received images can be posted at the ARISS Gallery <https://www.spaceflightsoftware.com/ARISS_SSTV/index.php>. You can also apply for the an award at the ARISS SSTV award <https://ariss.pzk.org.pl/sstv/> site. 73 Christy KB6LTY

(***) Watch for Livestream at https://www.youtube.com/channel/UCVW_nsutRMEfS2e8tURrltw and also at https://linktr.ee/zipariss2023 ARISS teams worldwide have come together to prepare an SSTV event for the 40th Anniversary of STS-9. SSTV from the ISS will be sent on 145.800 MHz using the PD120 format. Schedule is Sat 2023-12-16 at 10:15 UTC through Tue 2023-12-19 around 18:00 UTC The crossband repeater continues to be active. 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. 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 2023-12-14 18:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-12-14 18:00 UTC. (***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. 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.

Re: Coax length and connector style for M2 LEO antennas
by mikflathead＠aol.com 14 Dec '23

Welcome to the sat world, lot's of fun. I only operate RS-44 due to a high noise level on 2 meters. I would recomend a preamp for 435. It's a big help. The radio uses Pl's on 2 so I would not worry about that. Good luck see you on RS-44.

AO-73 back in transponder mode
by David G0MRF 13 Dec '23

13 Dec '23

After a year long period of 'battery management', AMSAT-UK and AMSAT-NL have restarted the transponder on AO-73. After 10 years in orbit, the battery on the satellite has reduced capacity and until recently, has been unable to charge to the nominal 8.3V.Following some careful battery management, where the transmitter was off during eclipse, the battery status has improved and the transponder has been reactivated. Although the battery voltage is varying between 8.13 in sunlight and 7.8V at the end of eclipse, this is much improved on the situation earlier in the year. Low power BPSK telemetry is transmitted on 145.935MHzThe inverting mode U/V transponder input is 435.130 to 435.150MHzThe transponder downlink is 145.970 to 145.950MHz At the moment the satellite has a high spin rate of apx. 30 rpm and if you've not used AO-73 before, the downlink can be Doppler tracked successfully, but the input on 70cms is best tuned manually due to temperature drift of the receiver. 73 David G0MRF - AMSAT-UK

ARISS conducts 60-80 of these special amateur radio contacts each yearbetween students around the globe and crew members with ham radio licenses aboardthe ISS. The Primary School of Zipari is located on the island of Kos in the Dodecanese in Greece. The Islandof Kos, with a population of 35,000, is in the southern part of the country.The school serves 400 students aged 6-12 and 45 teachers, and participates ininnovative programs such as European Erasmus+ programs and often takes part inPan-Hellenic competitions. This year an Astronomy School Club was formed toprepare students for this ARISS contact. Other student activities includeparticipation in the ESA Moon camp challenge (2nd and 6thgrade students), robot building, how to track the ISS, and amateur radiocommunication (including morse code). This will be a direct contact via Amateur Radio allowing students to ask their questions ofAstronaut Andreas Mogensen, amateur radio call sign KG5GCZ. The downlinkfrequency for this contact is 145.800 MHz and may be heard by listeners thatare within the ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contactis on the island of Kos in the Dodecanese in Greece. Amateur radio operators usingcall sign SV5BYR, will operate the ground station to establish and maintain theISS connection. TheARISS radio contact is scheduled for December 14, 2023 at 3:17:31 pm EET (Greece)(13:17:31 UTC, 8:17 am EST, 7:17 am CST,6:17 am MST, 5:17 am PST).

Does training prepare you? 12.How do you talk to your loved ones and how often do you get to? 13.Do you ever feel lonely or get bored on the Space Station? 14.What is the main danger you might encounter there? 15.How do you get treatment in space if you get sick? 16.What is your favorite sport? Can you play that in space? 17.What do you do for fun in space? 18.Which is your favorite planet and why? 19.Do you ever have to make repairs in space, and do they always go as planned?
