ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor [at] amsat.org You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ ANS-015 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2023 Jan 15 FalconSat-3 Nears Re-entry A number of amateurs and satellite watchers have put forward predictions concerning the date and time of re-entry for FalconSat-3. While all re-entry predictions are something of a guessing game, due to the large number of variables affecting the upper atmosphere, one thing that can be said for certain is that the end for FS-3 will be coming very soon, quite possibly within the next week. AMSAT Board Member and FS-3 control operator, Mark Hammond, N8MH, has stated that he will try to have the bird operational for its final hours. The satellite has only been available for approximately 24 hours each weekend due to weak batteries. FalconSAT-3 was built in 2005 and 2006 by cadets and faculty in the Space Systems Research Center at the US Air Force Academy in Colorado Springs, Colo. It is the fourth in a series of small satellites designed, built and operated there as part of a capstone course and which brings together about 30 cadets each year from several different academic departments. Since its launch on an Atlas V from Cape Canaveral in March, 2007, it has been through three mission phases. The first mission phase was operation of the science payloads. In the second it was used as a tool for training cadets in the space operations squadron and students in both undergraduate space training in California and graduate students at the Air Force Institute of Technology. Finally, it’s third mission phase was as an on-orbit resource in the Amateur Radio Service (ARS). Operation as an ARS satellite was being managed by AMSAT-NA. In amateur service the downlink is at 435.103 MHz transmitting 1W into a ¼ whip. The uplink is at 145.840 MHz and the receive antenna is a ¼ whip on the opposite side of the satellite. All UHF and S-band equipment on NTIA licensed frequencies has been disabled. The ARS VHF receiver is very sensitive. Modulation is 9600 bps GMSK for the uplink and downlink. The broadcast callsign is PFS3-11, and the BBS callsign is PFS3-12, Unproto APRS via PFS3-1. The core avionics were designed and built by Mark Kanawati, N4TPY, and Dino Lorenzini, KC4YMG at SpaceQuest Ltd. and have performed remarkably well for nearly 16 years on orbit. Jim White, WD0E, was the lead engineer for FalconSAT-3 at the Air Force Academy (USAFA) and managed the design, construction, testing and early operations of the satellite. Nearly 700 cadets at USAFA obtained their amateur radio licenses as part of training to operate FalconSAT-3 and other USAFA satellites. They have taken that knowledge and understanding of the value of the ARS into their Air Force service and many on into industry. Since FalconSAT-3 the USAFA Astronautics Department has built and operated one additional satellite and has two more queued for launch. The space operations curriculum and the ground station are being rebuilt and configured for these new space assets. The success of FalconSAT-3 is an excellent example of how amateur radio can be integrated into the curriculum of an education institution for the benefit of the students and the amateur radio service.

Pilot Warren "Woody" Hoburg, KB3HTZ; Commander Stephen Bowen, KI5BKB, and Mission Specialist Sultan Al Neyadi, KI5VTV, will join Mission Specialist Andrey Fedyaev on board the SpaceX Dragon spacecraft, Endeavour. The spacecraft will be atop a Falcon 9 rocket and, while a launch date has not been selected, the earliest date would be mid-February 2023. All crew members have learned about Amateur Radio on the International Space Station (ARISS), received guidance on studying and testing, and learned how to operate the ARISS radios and the basics of on-the-air protocol from ARISS team members at NASA's Johnson Space Center. The crew will be able to participate in ARISS, using the ham radio station on the ISS to contact schools and other educational institutions. ARISS is a cooperative venture of international amateur radio societies and the space agencies that support the ISS. In the US, participating organizations include NASA, the ISS National Lab, ARRL The National Association for Amateur Radio, and AMSAT.

It is not necessary and takes up valuable air time. If there are no QSOs ongoing, AND there is no station you heard that you want to call, you can key up and give your call and grid ONLY and unkey. But, please, do this sparingly! Instead of doing it over and over, listen and wait for another station you might want to work. In other words, you have to give others a chance to get in there. I have heard many passes where it was constantly one station after another CQing or announcing their call and I couldn't get it to call anyone! And if there is a rover on the pass giving out a rare grid, it is customary to let them have the air and work as many stations as they can until they have worked them all who are seeking them. (Which will changes as the sat passes over new territory and new callers wanting to work the rover come into range.) It may mean you get only one QSO that pass (or none of you don't need the grid he is in) but it's about sharing a resource wisely and giving everyone the most benefit. A pass full of CQs or a pass of contacts where everybody makes one QSO with a rare grid. If you add up all the seconds spent by people CQing, or continually announcing themselves you'll see what a significant percentage of a pass is wasted. They say, 'Well no one else was on.' Right... because they couldn't get through due to all the CQing! Satellites is like HF DXing... listen, listen and when in doubt, listen. Then there is the simple fact that CQing has NEVER been a thing on the FM mode... not on repeaters, not on simplex. The longstanding custom on FM, because of the nature of the way the audio works, is to simply announce your call. Such as, 'N4UFO listening 52" on 146.520 simplex, or 'N4UFO monitoring' over a 2m FM repeater... the 'CQ' part is implied. That said, why is CQing on SSB not only okay, but necessary? FM birds are one channel and you can hear everyone plain as day right there. With linear birds, there is a passband and stations are spread out... CQing is for catching everyone else's attention as they tune around. They will hear either your high pitched squeaky voice or low rumbling voice speaking in the familiar rhythm of 'CQ, CQ, CQ' as they tune around. In short, they use your 'CQ' as a way to tune around and FIND you, then TUNE you in. This is not necessary on FM. And also not necessary to CQ on SSB once the station starts making contacts. There is also a tendency on linear birds when a rare grid station is expected to be on a pass to start blind calling. Please do not do that either! I have a short writeup on my rover page to explain it... it's on the bottom of the page here: https://www.qrz.com/db/N4UFO/P (also pics & stories of my roving adventures & my gear) And THANK YOU for ASKING!!!

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.

Upcoming ARISS Contact Schedule as of 2023-01-13 02:00 UTC

12 Jan '23

Upcoming ARISS Contact Schedule as of 2023-01-13 02:00 UTC Quick list of scheduled contacts and events: Escola Secundária de Lagoa, Lagoa, Azores, telebridge via IK1SLD The ISS callsign is presently scheduled to be OR4ISS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Josh Cassada KI5CRH Contact is go for: Thu 2023-01-19 18:20:34 UTC 55 deg (***) Nizhny Novgorod, Russia, direct via TBD The ISS callsign is presently scheduled to be RSØISS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is TBD Contact is go for 2023-01-24 TBD Krasnodar, Russia, direct via TBD The ISS callsign is presently scheduled to be RSØISS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is TBD Contact is go for 2023-02-TBD TBD 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. ####################################################################################################################################### 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 2023-01-13 02:00 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 2022-12-17 02:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf The ARISS webpage is at https://www.ariss.org/ Note that there are links to other ARISS websites from this site.

As some of you have links to my website, I want to let you know the domain has changed. ivok.home.xs4all.nl changed to ivo.digiterraan.nl. So for the most popular sat pages: The G-5500 Elevation Rotor Repair page: Old: https://ivok.home.xs4all.nl/pa1ivo/G-5500.html New: https://ivo.digiterraan.nl/pa1ivo/G-5500.html The portable satellite setup page: Old: https://ivok.home.xs4all.nl/pa1ivo/portable_satellite_setup.html New: https://ivo.digiterraan.nl/pa1ivo/portable_satellite_setup.html The old pages are at the moment redirected to the new pages, but the old pages will disappear in the (near) future. Happy experimenting, 73, Ivo PA1IVO

Mark, I tried with MIR-SAT 1 (MO-112) but was off in spite of expert advices by over 24 hrs, guess it is a lottery, point of re-entry not accurate as spanned over 4 hours. I therefore suggest that we all keep an watch +/- one day of expected re-entry and it would be nice to capture its last signals and determinate its re-entry approximate location. To motivate all to try to capture the last telemetry of F3, in my capacity of MARS President I wish to inform all that MARS will issue a special Award for last formal telemetry received from F3 and you will also receive a MO-112 national first day cover (our first 3B8 HAM bird being honored with a 3B8 national postal stamp, for your collection). Mark, we will liaise on the side to validate the winner data. I take this opportunity to thank Mark for is great work maintaining F3 for the benefit of the HAM community worldwide for many years, personally I enjoyed working F3 many times, I believe that there are many others who will join me to give a great applause to Mark for his great contribution. I will try to be at the F3 passing away just to say good bye (orbit depending), but thanks also to all the team who designed and build such a successful bird. 73 Jean Marc (3B8DU) > On Jan 10, 2023, at 4:00 PM, Mark L.

Hi Vince. I've only been a member for less than a year but this QUIET email reflector seems to be the norm. When I questioned that myself, I was told by others that Satellite ops "all" communicate via Twitter. I have checked that out and see there IS a lot of satellite-related traffic there. But I simply can't get used to the mechanics of Twitter so I rarely look at it. IMHO it would be nice to have a nice well-attended email reflector like the ones the guys who do VHF, Contesting, Moonbounce (EME), Boatanchors, etc. etc. have. 73, Barry K6RM On Thu, Jan 5, 2023 at 11:24 AM Vince Fiscus, KB7ADL via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > Testing here, > I've haven't seen any Amsat-BB activity in > three to four days. > > Just testing to see if my email provider > is filtering it as spam. > > KB7ADL > > > ----------------------------------------------------------- > > Sent via AMSAT-BB(a)amsat.org.

Upcoming ARISS Contact Schedule as of 2023-01-06 17:00 UTC Quick list of scheduled contacts and events: Escola Secundária de Lagoa, Lagoa, Azores, telebridge via IK1SLD (***) The ISS callsign is presently scheduled to be OR4ISS (***) The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Josh Cassada KI5CRH (***) Contact is go for: Wed 2023-01-18 17:32:02 UTC 41 deg (***) 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. ####################################################################################################################################### 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.

Hello everyone: According to my latest simulation, FalconSat will reenter on Jan 22, 2023 at 16:6:6 EST. Just wanted to let people know. It's not super accurate because things speed up unpredictably during the end, but it's a fairly good estimation I think. 73! VE3SVF

You are going to run into serious trouble if you live near high power transmitters, especially FM. The front end of the RTL-SDR has poor large signal handling capabilities.

AMSAT NEWS SERVICE ANS-008 In this edition: * Story of SuryaSat-1 (SS-1) Nano Satellite * VUCC Satellite Standings as of January 1, 2023 * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over The AMSAT News Service bulletins are a free, weekly news and information service of AMSAT, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor [at] amsat.org You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ ANS-002 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2023 Jan 08 Story of SuryaSat-1 (SS-1) Nano Satellite This afternoon 6 January 2023, at 07:50 UTC, there will be the culmination of the long journey of Surya Satellite (SS-1) Nano Satellite project that started in 2016 after a presentation of amateur radio activities by ORARI (the Indonesian Radio Amateurs Organization) to students of University of Surya. In early 2015 ORARI made a presentation to University of Surya Robotic Club, and one of the amateur radio activities that got their interest was high-altitude ballooning due to the telemetry aspect, such as sending temperature, altitude, voltage, as it relates to their robotic interest. I showed them a couple pictures of my past activity in ARHAB as the faculty advisor of amateur radio society at Texas Tech University in early 2000. This started the high-altitude balloon planning, including designing the balloon payload (APRS utilizing OpenTracker mini board). Late 2015, with the successful launch and activation of LAPAN-A2/ORARI (which becomes IO-86) satellite, the students grew interest of building a satellite as it is only a couple of kilometers higher they said. So in 2016 the ORARI team visit them and shared the experience in designing a satellite, as I myself was part of the ORARI team that involved in the design of the amateur payload in the LAPAN-A2/ORARI. As this would be their first effort in building a satellite from scratch, they said we will start with APRS then next satellite would be a voice repeater satellite. They submitted the design in a competition by UNOOSA and won. The student got more excited after seeing the POC (proof of concept) worked and they continue with building the prototype, conducted various tests with LAPAN (the aeronautical and space organization) and complying with the necessary paperwork/approvals. But the road wasn’t easy as they got funding problem (at one time they were selling T-Shirt to raise funding), change in faculty advisor and university leadership and their own graduation and transition into the professional world (some of them got employed in commercial satellite companies). Finally they got back in the last 2 years to finalize the payload, had the payload verification with ORARI team and shipped the payload to Japan (JAXA), integrated with other payload and shipped to the US, then lifted up on Space-X CRS-26 rocket to ISS last November and now today is the deployment date from the Kibo Module of ISS. Apologize for the long posting but I got really excited today as the deployment of SS-1 Nano Satellite is coming up shortly. Update: SS-1 has been deployed at 08:03 UTC on 6 January 2023 please monitor APRS beacon at 145.825 MHz [ANS thanks Yono Adisoemarta, YD0NXX / N5SNN, ORARI HQ, Head of Satellite Division, for the above information] +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ The 2023 AMSAT President's Club coins are here now!

Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/ At the request of CAMSAT and the XW-4 (CAS-10) team, AMSAT has designated the satellite as Hope-OSCAR 119 (HO-119) as of January 1, 2023. For details, see Drew Glasbrenner, KO4MA and OSCAR Number Administrator's announcement entitled "OSCAR number assigned for CAS-10" in AMSAT News Service Bulletin ANS-001 (dated January 1, 2023). Therefore, the following satellite has been renamed in this week's AMSAT-NA TLE distribution as follows: HO-119 NORAD Cat ID 54816. (Formally CAS-10). The following satellite has decayed from orbit and has been removed from this week's AMSAT-NA TLE distribution as follows: TW-1A NORAD Cat ID 40928. (decayed from orbit on 12/29/22 per Space-Track). Finally, AMSAT is pleased to announce the new daily two line element bulletin available at https://www.amsat.org/tle/current/daily-bulletin.txt. Members of the Sci-Tech Radio Society (STARS) have worked with AMSAT Information Technology to automate this process. Seventeen year old STARS member Ryan "RJ" Fitzgerald, N1BGA, enjoyed exercising skills he learned in his high school computer science class. "It was cool to do something for the real world beyond just homework assignments, plus it forced me to learn stuff not covered in class" said Fitzgerald. STARS is part of New England Sci-Tech - a non-profit STEM education center and makerspace dedicated to project-based, hands-on learning for youth and families across the New England community with a strong Amateur Radio focus. Visit www.nescitech.org for details. Thanks to Joe Fitzgerald, KM1P, for this update on this new innovative approach to AMSAT TLE distribution. [ANS thanks Ray Hoad, WA5QGD, AMSAT Orbital Elements Manager, for the above information] --------------------------------------------------------------------- ARISS News Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide. No upcoming contacts currently scheduled Special thanks to our ARISS telebridge ground stations. Approximately 38% of the ARISS school contacts are handled by the ARISS telebridge stations. Thanks to following stations: AB1OC, IK1SLD, K6DUE, NA7V, ON4ISS, VK4ISS, VK4KHZ, VK5ZAI, VK6MJ, and ZS6JON. 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. 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.

This launch carried 114 satellites to orbit. The article says "The Transporter 6 launch also placed into orbit... an amateur radio CubeSat from the Czech Republic." I assume that is a reference to BDSAT-2, which is supposed to carry a AX.25 GFSK G3RUH 9600 baud digipeater with downlink at 436.025, according to http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=866 This is confirmed by https://www.bdsat.cz/ That website shows "VHF Downlink frequency: 145.850 MHz," but the IARU says the VHF frequency is an uplink. (Thanks to Mark Johns, K0JM, SpaceFlight Now, and the IARU) + The TJREVERB are seeking a couple of stations skilled in communicating with satellites using APRS. The Thomas Jefferson High School for Science and Technology's TJREVERB satellite was deployed from the ISS on Dec 29th, and the team is still trying to successfully make contact with it. Please contact Curt Laumann, K7ZOO, if you're interested in assisting. His email address can be found on QRZ.com + Congratulations to Hector Martinez, W5CBF, who finished his Satellite Worked All Zones (WAZ) award through QSOs using IO-117's MEO digipeater. Only about 16 CQ zones are workable on LEO satellites from his QTH in Louisiana, so the MEO digipeater was able to fill in the rest. His award is the 42nd Satellite WAZ issued. Satellite WAZ requires confirmed QSOs with 25 of 40 CQ zones and is sponsored by CQ Magazine. Confirmations through LoTW are accepted. + Want to try something different? FO-118 carries a linear transponder with a 70cm downlink and a 15 meter uplink. The 15 meter uplink is very sensitive. This week's editor made a couple of QSOs using 5 watts from his FT-817ND to an AlexLoop Walkham Portable Magnetic Loop and was able to access the transponder with strong signals through the pass. + UVSQ-SAT will mark 2 years in space on January 24, 2023. In celebration of this milestone, the FM transponder will be activated. The uplink is 145.905 MHz and the downlink is 437.020 MHz. No PL tone is required.

SS-1 Satellite - First 24hr Report
by P. Suryono Adisoemarta 07 Jan '23

07 Jan '23

Quick SS-1 (Surya Satellite 1) Report after a meeting with the SS-1 Satellite team an hour ago:- SS-1 was deployed at 08.03 UTC on Jan 6, 2023- Right on schedule, 30 minutes after deployment first packet was heard. This packet was digipeated via ISS as it is still close-by- From the telemetry bits, both VHF and UHF antennas were properly released- Battery voltage was observed at 3.83 volt- At around 13.00 UTC SS-1 went quiet, the team concluded it went into "hibernation mode" due to low voltage- This morning at around 00.30 UTC one observer in Bali received a direct (not digipeated) packet, so it came out of hibernation mode with high voltage as the radio power is high- Consecutive packets were received direct by various APRS satgates- At around 07.00 UTC telemetry shows a critical low battery voltage and SS-1 went into hibernation again- As the SS-1 team concluded that the satellite is working as designed, 2 hours ago when SS-1 pass above Jakarta, the team uplink commands to reduce the beacon rate, to raise the battery voltage, and gather more data points on the power budget model. 73 de Yono - YD0NXXORARI HQ - Head of Satellite Division

There is also a new TLE set for SS-1, not very accurate but it should be better than following ISS TLE: SS-1 1 99369U 23006.23627038 .00000000 00000-0 25952-3 0 07 2 99369 51.6447 51.3209 0004899 231.6381 242.1444 15.51123116 06 Source: https://community.libre.space/t/iss-deployment-jaxa-j-ssod-24-2023-01-06-07… 73, fredy On 1/7/23 10:31, Jean Marc Momple via AMSAT-BB wrote: > Thanks Fredy for having confirmed. > > 73 > > Jean Marc (3B8DU) > >> On Jan 7, 2023, at 11:37 AM, Alfredos (fredy) Damkalis via AMSAT-BB <amsat-bb(a)amsat.org> wrote: >> >> Yes this is the callsign of SS-1. >> >> By the way SS-1 is active on both UHF and VHF, but difficult to catch it on VHF as it is still close to ISS and its APRS repeater.
