AMSAT NEWS SERVICE ANS-009 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/ In this edition: * The ARRL Foundation Grants an Award for the ARISS *STAR* Keith Pugh Memoriam Project * EASAT-2 and Hades Satellites with FM Repeaters Scheduled for Launch on January 13th * Changes to AMSAT TLE Distribution for January 6, 2022 * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over ANS-009 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2022 Jan 09 The ARRL Foundation Grants an Award for the ARISS *STAR* Keith Pugh Memoriam Project ARISS‐USA is known for engaging students in STEAM (science, technology, engineering, arts, and mathematics) subjects by arranging live question-and-answer sessions via amateur radio (ham radio) between K‐12 students and astronauts on the International Space Station (ISS). In the last two decades, over 1,400 contacts have connected more than one million youth using amateur radio, with millions more watching and learning. ARISS is constantly pursuing educational opportunities that inspire student interest and outcomes. ARISS-USA is pleased to announce that the ARRL Foundation awarded funding for the first year of a two-year project called the “ARISS *STAR* Keith Pugh Memoriam Project” with *STAR* being the acronym for Space Telerobotics using Amateur Radio. The ARRL Foundation very generously provided $47,533. The project honors the memory of highly-respected Keith Pugh, whose call sign was W5IU (Silent Key, May 2019). He was an expert supporter of ARISS for many years, a star ARISS Technical Mentor assisting schools with their ARISS contacts, finding educators who might be interested in learning about ARISS, and going to schools to lead youth in a variety of lessons about wireless radio technology. ARISS *STAR* (short for ARISS *STAR* Keith Pugh Memoriam Project), is a brand-new education program that will enable US junior high and high school education groups to remotely control robots through digital APRS (Automatic Packet Reporting System) commands using amateur radio. Year 1 focuses on systems development and initial validation of *ARISS* STAR, and Year 2 focuses on evaluation and final validation. Systems development and evaluation will be led by university staff and students who will undertake hands-on-wireless and telerobotics lesson development, learn about Amateur Radio, and support the development of the *STAR* engineering hardware and software. Next, youth teams will be selected to experiment and critique *STAR* telerobotics scenarios along closed courses and radio lessons. Some participating students will want to prepare for, and earn, their amateur radio licenses, using ham radio to learn and practice concepts in radio technology and radio communications. Overarching goals for *STAR* are to improve and sustain ARISS STEAM educational outcomes with youth. Robotics is gaining popularity among youth and adults alike. Telerobotics adds a wireless accent to robotic control. *STAR*, therefore, gives ARISS a new educational dimension to attract the attention of more education groups and their students and educators—outreach that promises to attract new audiences. The ARRL Foundation was established in 1973 by ARRL, The National Association for Amateur Radio ®, and advances the art, science and societal benefits of the Amateur Radio Service by awarding financial grants and scholarships to individuals and organizations in support of their charitable, educational and scientific efforts. ARISS-USA Executive Director Frank Bauer, KA3HDO, praised the ARRL Foundation, saying, “ARISS team member, Keith Pugh, W5IU, poured his energy into inspiring, engaging and educating youth in space and in amateur radio endeavors. What a better way to honor Keith than through the ARISS *STAR* initiative. We thank the ARRL Foundation for their vision to move this initiative forward. Maybe someday one of our ARISS *STAR* students will use their telerobotics skills to control scientific rovers on the Moon or Mars!” [ANS thanks ARISS for the above information] +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ The 2022 AMSAT President's Club coins have arrived!

As it has been noted in older posts, both satellites offer voice communications in FM and data retransmission in FSK or AFSK up to 2400 bps, such as AX.25 or APRS frames. They also transmit voice beacons in FM with the callsigns AM5SAT and AM6SAT, as well as CW, and, in the case of Hades, SSTV live images too. We thank you in advance for trying to receive their signals and of course for trying to use the repeater. EASAT-2 one will be automatically active 30 minutes after the launch although it would be a priority for us trying to have some telemetry frames first to check if all is working properly. I tell you a bit more about the satellites: EASAT-2 has been designed and built jointly by AMSAT-EA and students from the European University of Degrees in Aerospace Engineering in Aircraft and in Telecommunication Systems Engineering, with contributions from ICAI in the communications part, and it incorporates as an experimental load a basalt material from Lanzarote, similar to lunar basalts, provided by the CSIC research group on meteorites and planetary geosciences at the Institute of Geosciences, IGEO (CSIC-UCM) and that could be used as a construction material on the Moon. This project was promoted and has the collaboration of the ETSICCP (UPM). The UNESCO world geopark of Lanzarote and the Chinijo archipelago has been used for different investigations as an analogue of the Moon and Mars, also including the training of ESA astronauts. The selected basalt material meets the requirements to be used as a simulant of the existing basalt on the Moon. The purpose of the experiment is to determine its evolution in space based on periodic measurements of some of its properties. Although the experiment is limited and constitutes the first phase of this type of study, it represents an important milestone as it is the first of its kind to be introduced on such a small satellite. As for Hades, its payload consists of a miniature camera module that outputs the captured images as an audio signal in SSTV mode. The SSTV formats it uses are compatible with Robot36, Robot72, MP73 and MP115. The design of the cam module is based on the one used in the successful mission of the PSAT2 satellite, an amateur radio satellite of the United States Naval Academy and the Brno University of Technology. This camera has been operational since June 25, 2019: (http: // www.aprs.org/psat2.html). The camera chip is the Omnivision OV2640, which provides a resolution of up to 2M pixels and compressed JPEG output. The resolution is limited by the internal memory of the CPU (MCU) that controls the camera to 320x240 (typical) or 640x480 maximum. The MCU selected for the control is the STM32F446RET6, which has the smallest possible footprint with connection to a DCMI peripheral, necessary for the connection with the camera. Images can be stored in 2MB serial flash memory. The complete SSTV encoder has managed to be implemented on a 4 layer PCB with dimensions of only 38x38mm. The MCU can be fully controlled from ground stations. The firmware allows the sending of live camera images, images previously saved in flash memory, or images encoded in ROM. It also provides PSK telemetry and imaging advance scheduling with current status (event counters, temperature, voltage, light conditions, etc.) and a brief summary. The described module has been developed and manufactured in the Department of Radioelectronics of the Brno University of Technology in the Czech Republic. Both hardware and firmware designs with the source codes will be available on Github under the MIT license (https://github.com/alpov/SatCam). As noted, initially only the EASAT-2 repeater is active. Hades one will be activated by remote control a few days after launch. The frequencies coordinated with IARU for both satellites are as follows: EASAT-2 145.875 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps 436.666 MHz downlink, Modes: FM voice, CW, FSK 50 bps, FM voice beacon with AM5SAT callsign HADES 145.925 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps 436.888 MHz downlink, Modes: FM voice, CW FSK 50 bps, SSTV Robot 36, FM voice beacon with callsign AM6SAT The description of the transmissions can be found in the following document. https://www.amsat-ea.org/app/download/12530621/AMSAT+EA+-+EASAT-2+and+HADES… AMSAT-EA appreciates the receipt of telemetry, voice beacons and SSTV images.

In addition to his numerous contributions to AMSAT and the worldwide amateur satellite community, Ray was also the long time organizer of AMSAT's CW Activity Day - previously AMSAT Straight Key Night - held in conjunction with the ARRL's event on New Year's Day. In recognition of Ray's long time service to AMSAT and his keen interest in CW operating via satellite, AMSAT is pleased to announce that AMSAT's CW Activity Day will now be known as the W2RS Memorial AMSAT CW Activity Day in Ray's honor. The rules are simple - operate CW through any amateur satellite between 0000 UTC and 2359 UTC on January 1, 2023. Straight keys and bugs are encouraged, but not required. Logs are not required, but operators are encouraged to submit a report of their activity to the AMSAT-BB. Photos and video clips of activity are also encouraged - post them on Twitter and tag @AMSAT. Remember to use the minimum power required for communication as constant carrier modes, including CW, can disrupt transponder operation for other users.

On Tuesday, Dec. 27th, they pinged a passing space rock with shortwave radio waves at 9.6 MHz. This could allow them to see *inside* the asteroid. A number of amateur radio operators around the world were able to copy the signal. The signal appeared in a sequence of frequency sweep pings centered aroun the the 9.6MHz frequency in a "Ping" Wait 2 seconds. "Ping" Wait 2 seconds "Ping" pattern. That's what most ham radio operators heard last Tuesday when they received HAARP's radar transmission to asteroid 2010 XC15. Scott Tilley of Roberts Creek, British Columbia, provided a recording of what he saw. It may be viewed at: https://bit.ly/3C2YshF along with a vidoe that includes sound. The pulse was lopsided with a fast rise and a slow decay," notes Tilley. "I believe this is due to multipath propagation from HAARP in Alaska to my receiver in British Columbia." Everyone who picked up the pulse did so because Earth's ionosphere reflected some of HAARP's radio energy back to Earth. Only a fraction escaped into space and reached the asteroid. Tilley's high-time-resolution recording of the pulse shows that multiple reflections (probably with a dash of ducting and refraction) were involved. The complexity of the ionosphere, and how it modifies shortwave signals, is a key challenge for researchers who will be processing radar returns from asteroid 2010 XC15. Good luck to the radar team as we await their results! [ANS thanks spaceweather.com for the above information] --------------------------------------------------------------------- Space junk bill passes Senate unanimously U.S. Senator John Hickenlooper applauded Senate passage of his Orbital Sustainability (ORBITS) Act, a bipartisan bill to establish a first-of-its-kind demonstration program to reduce the amount of space junk in orbit. The bill passed the Senate unanimously. "From satellite communications to rockets carrying humans into deep space, space debris is a massive threat to space operations," said Hickenlooper, chair of the Senate Subcommittee on Space and Science. "I'm over the moon that our ORBITS Act passed and we can start cleaning up this space junk." Space junk, or orbital debris, currently threatens human space exploration, scientific research missions, and emerging commercial space services. There are approximately 8,000 metric tons of debris currently in orbit, including at least 900,000 individual pieces of debris that are potentially lethal to satellites. Because of the magnitude of the current debris, simply preventing more debris in the future is not enough. The ORBITS Act will jumpstart a program focused on research, development, and the demonstration of technologies capable of safely carrying out successful Active Debris Remediation (ADR) missions to create a new market for these services.

TJREVERB was launched on November 22 from Kennedy Space Center, Florida as part of the SpaceX-26 Commercial Resupply Service Mission en route to the International Space Station. The launch is the culmination of seven years of hard work for TJ Space. Led by Robotics lab director Kristen Kucko, many students from Thomas Jefferson High School for Science and Technology have had a hand in this historic launch. A statement and description of the mission by Michael Roth and Kristen Kucko of Thomas Jefferson High School states: TJ REVERB is significant because the CubeSat was designed, built, coded and integrated entirely by high school students, said Kucko. The students did not use a satellite kit, nor did they have an industry or university partnership to assist them. Building satellites is not an easy task. According to Col. Nick Hague, Astronaut, (some)countries have not been able to build CubeSats. The students in TJ Space should be proud of their accomplishments. Additional information about the project may be found at: https://tjhsst.fcps.edu/features/launch-tjreverb-culmination-seven-year-proj ect-tj-space Kirsten Kucko, the teacher sponsoring the TJ Space team wrote, "TJ Space received crowdsourced reports that there is an APRS unit digipeating within the vicinity of the ISS. The spacecraft has the orbital characteristics of one of the satellites launched during the NRCSD 24 mission. " Since TJREVEB is the only CubeSat using APRS in that vicinity, TJREVERB could very well be that spacecraft. It is TJ Spaces assertion that something went critically wrong with TJREVERBs implementation of the Iridium radio and Iridium did not receive power to turn on. The APRS radio powered on as the backup radio and started digipeating. TJ Space continues to search for confirmation that this spacecraft is indeed TJREVERB. Any help from the community would be greatly appreciated.

RTL-SDR type preamp on the birds?
by James Hickox 29 Dec '22

29 Dec '22

Hello. After many years away, I am beginning to get a shack ready to start using the satellites again. This time, I cannot go with the best hardware and will.need to do some compromises. I played with the SDR dongles awhile back and used one of the $20 wideband preamps. My question: if I were to set the preamp up with a diplexer as an input filter and 50 ohm terminations for protection along with the proper relays, could this preamp be useful if mounted near the antenna feed point? I cannot seem to find out any comparisons or testing against other homebrew or commercial units. Thanks and 73, James, AA5AO

The 70cm band is hamonically related to the 2m band. 2m into 70cm 3rd harmonic interference is more likely than 70cm into 2m.

FT-818ND and FTM-400XDR will be discontinued
by Alan 28 Dec '22

28 Dec '22

From John Kruk, national sales manager, so it is official and not a rumor: ANNOUNCEMENT - Dec.28th, 2022 Please be informed that the production of the FT-818ND and FTM-400XDR will be discontinued. We are forced to make this unfortunate decision due to difficulty we are having with the availability of some components. We appreciate your long-term patronage of the FT-818ND and FTM-400XDR. There seem to be some of both available, or in the pipeline. 73, Alan WA4SCA ----------------------------------- The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present - and is gravely to be regarded.

Re: UHF preamps

Tom, Are you relying on the transmit RF sensing feature of this 432 MHz preamp? RF sensing can be unreliable. You might use the FT-847's RF amp enable output to trigger the external preamps. Another thought. It is possible that your 2m transmit signal is leaking into the input of the 70cm preamp. It's likely that significant coupling is occurring at the arrow antenna. You might consider using separate preamps and isolating relays. 73 - Paul - W2HRO On Mon, Dec 26, 2022 at 11:32 PM tjschuessler--- via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > For my portable/temporary satellite antenna rig, I have need of using a > UHF preamp, which I have strapped to the tripod that holds and aims my > Arrow antenna.

Upcoming ARISS Contact Schedule as of 2022-12-27 16:30 UTC
by aj9n＠aol.com 27 Dec '22

27 Dec '22

Upcoming ARISS Contact Schedule as of 2022-12-27 16:30 UTC Quick list of scheduled contacts and events: 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.

In addition to his numerous contributions to AMSAT and the worldwide amateur satellite community, Ray was also the long time organizer of AMSAT's CW Activity Day - previously AMSAT Straight Key Night - held in conjunction with the ARRL's event on New Year's Day. In recognition of Ray's long time service to AMSAT and his keen interest in CW operating via satellite, AMSAT is pleased to announce that AMSAT's CW Activity Day will now be known as the W2RS Memorial AMSAT CW Activity Day in Ray's honor. The rules are simple - operate CW through any amateur satellite between 0000 UTC and 2359 UTC on January 1, 2023. Straight keys and bugs are encouraged, but not required. Logs are not required, but operators are encouraged to submit a report of their activity to the AMSAT-BB. Photos and video clips of activity are also encouraged - post them on Twitter and tag @AMSAT. Remember to use the minimum power required for communication as constant carrier modes, including CW, can disrupt transponder operation for other users.

Re: UHF preamps

I have two of the SSB preamps — one at home and one strapped to the portable tripod and they’re really solid. Using an IC 9700, they can be turned on and off from the radio. When on, they tx/rx switch just fine and they can handle anything the 9700 might throw at them on tx.

UHF preamps
by tjschuessler＠verizon.net 26 Dec '22

26 Dec '22

For my portable/temporary satellite antenna rig, I have need of using a UHF preamp, which I have strapped to the tripod that holds and aims my Arrow antenna. I find that my FT847 is just not as sensitive on 70 CM as it is on 2M. I have been using an ARR (Advanced Receiver Research ) SP432VDG which is supposed to have a maximum power pass through imitation of 25watts. I try to be pretty careful as to how much output I run through the thing, maybe limiting to 15 watts or so. Unfortunately, I have blown the preamp out several times, even with being conscious of the RF level. I sent the pre to them, they repaired and sent back. I recently discovered that I had blown my unit again. Symptom is that it adds noise to the output, but does not amplify any signals coming into it from the antenna. I have sent the unit in to ARR in the past for repair. This time I am contemplating replacing this one with a more robust device that might be able to handle more RF running through it (RF sensing means you will still hit the device with an instantaneous burst of RF before the internal relays kick in. A friend has confided that he has the higher power version of the ARR Preamps, but has had similar problems with killing the things. Thus I am in the market for maybe another option. While I oft times, will stroll over to the antenna tripod, and barrel off the cables going to and from the preamp to bypass completely from the transmit chain, this is kind of a pain, even in a portable situation. I looked at M2s web site and can find a 2 Meter amp, but no 70CM (Might be missing something. I have heard a lot of good things on the SSB preamps, but the only pace I can see them being sold, is Dolstra in Europe. Don't see a US vendor. Looking for suggestions. I would be interested in buying pre-owned, if someone had a Preamp that would like a new home. I do have a question for Yaesu FT847 users. With that radio, you can power a Preamp via the built in Bia- T power inserter, And assume that when this mode is turned on, it cuts the inserted DC to the preamp as the tranciever goes into transmit. Does this work fast enough to protect, even RF switched preamps? That might be a good safety measure as I have traditionally used external DC to power my preamps. Wisdom from the cloud here would be much appreciated. . Tom Schuessler, N5HYP

Earlier this year, nine schools and organizations were selected for contacts that will take place from January to June 2023 with the ISS. The primary goal of the ARISS program is to engage young people in science, technology, engineering, arts, and math (STEAM) activities that raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and Amateur Radio. ARISS anticipates that NASA will be able to provide scheduling opportunities for these host organizations in the U.S. between July - December 2023: - A.L. Burruss Elementary School, Marietta, GA - Augusta Preparatory Day School, Augusta, GA - Bowman Middle School, Bakersville, NC - Camp William B. Snyder, Haymarket, VA - Covenant Christian Academy, West Peabody, MA - Orangeburg Christian Academy, Orangeburg, SC - Webb Bridge Middle School, Alpharetta, GA The 16 schools and organizations selected for 2023 are now working to complete an acceptable plan that demonstrates their ability to execute a ham radio contact with the ISS. Once their equipment plan is approved by the ARISS Technical Mentors, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA. [ANS thanks the ARRL for the above information.] --------------------------------------------------------------------- SSTV Unit on ISS is Inoperable The ARISS SSTV capability is currently not operational. The SSTV card that interfaces with the ISS computer was damaged and cannot be reliably used. Also, ISS has recently switched to a new complement of laptops, which requires the ARISS Russia team to develop a new computer interface to support SSTV. ARISS Russia has been actively working this new development and is consulting with the ARISS International hardware/software team on these efforts. Sergey Samburov, RV3DR, ARISS Russia leader, has stated that they expect to complete the SSTV development effort early next year and launch the hardware on a future Progress flight later in the year. Until then, SSTV operations will be down. The ARISS International team will keep all informed about SSTV status through its web site http://www.ariss.org and its social media outlets.

The exponential growth of communities subject to private land use restrictions that prohibit both the operation of Amateur Radio and the installation of amateur station antennas has significantly restricted the growth of the Amateur Radio Service. These restrictions are pervasive in private common interest residential communities such as single-family subdivisions, condominiums, cooperatives, gated communities, master-planned communities, planned unit developments, and communities governed by community associations. The restrictions have particularly impacted the ability of Amateur Radio to fulfill its statutorily mandated duty of serving as a voluntary noncommercial emergency communications service. Congress in 1996 directed the Federal Communications Commission (FCC) to promulgate regulations (Public Law 104-104, title II, section 207, 110 Stat. 114; 47 U.S.C. 303 note) that have preempted all private land use restrictions applicable to exterior communications facilities that impair the ability of citizens to receive television broadcast signals, direct broadcast satellite services, or multichannel multipoint distribution services, or to transmit and receive wireless internet services. ARRL attempts to obtain similar relief for Amateur Radio were rejected by the FCC with a statement such relief would have to come from Congress. ARRL Legislative Advocacy Committee Chairman John Robert Stratton, N5AUS, noted that Congress, in 1994 by Joint Resolution, S.J.Res.90/H.J.Res.199, declared that regulations at all levels of government should facilitate and encourage the effective operation of Amateur Radio from residences as a public benefit. He continued by stating that "H.R.9670, the Amateur Radio Emergency Preparedness Act, is intended to fulfill that mandate and preserve the ability of Amateur Radio Operators to continue to serve as a key component of American critical communications infrastructure."

Mission Space Lab is part of the European Astro Pi Challenge, an ESA Education programme run in collaboration with us at the Raspberry Pi Foundation. Mission Space Lab teams can choose between ‘Life on Earth’ and ‘Life in space’ for their experiment idea. A panel of 25 judges from the Raspberry Pi Foundation and ESA Education assessed the submitted ideas. They were restricted in how many teams could be accommodated, as time to run experiments on board the ISS is limited, especially for ‘Life on Earth’ experiments which need time in a nadir window. The standard of the submitted ideas was higher than ever, making this the toughest judging yet. The judges were delighted are delighted to announce that 486 teams will move on to Phase 2 of Mission Space Lab: writing the code for their experiments. All the teams whose experiment ideas were selected will receive a special Astro Pi hardware kit, customised to their idea, to help them write and test the Python programs to execute their experiments. Once the teams of young people have received their kits, they can familiarise themselves with the Astro Pi hardware and then create and test (and re-test!) their programs.

[ANS thanks ARRL Letter for the above information.] + Possibly due to a micrometeoroid or debris strike, the Soyuz MS-22 capsule docked to the ISS has suffered an external radiator coolant leak. If it is determined to be unsafe for a crewed return trip, cosmonauts Sergey Prokopyev and Dimitri Petelin along with NASA astronaut Frank Rubio would be effectively trapped until a replacement could be launched. That replacement, the Soyuz MS-23 capsule, is apparently being accelerated for a potential uncrewed launch and would be remotely piloted to the ISS. This is possibly the most significant "emergency" situation in the 20+ year history of the ISS. [ANS thanks The Orbital Index for the above information.] + Another roll-out solar array was installed and deployed by astronauts Frank Rubio and Josh Cassada outside the International Space Station on a spacewalk Thursday, Dec. 22, a day later than previously planned after the space station needed to dodge a piece of space junk. The original solar panels launched on four space shuttle missions from 2000 to 2009. As expected, the efficiency of the station's original solar arrays has degraded over time. NASA is upgrading the space station's power system with the new roll-out solar arrays - at a cost of $103 million - which will partially cover six of the station's eight original solar panels.

Upcoming ARISS Contact Schedule as of 2022-12-23 17:00 UTC
by aj9n＠aol.com 23 Dec '22

23 Dec '22

Upcoming ARISS Contact Schedule as of 2022-12-23 17:00 UTC Quick list of scheduled contacts and events: 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 2022-12-23 17:00 UTC.

SatPC32ISS with DXLab
by jeff griffin 23 Dec '22

23 Dec '22

I just received this from Erich, the SatPC32 author. I made the changes to my Program Files (x86) SatPC32 directory. All is working 100%. It's nice to be able to auto log the IO-117 QSO's :-) Thank you Erich... 73 and a HNY Jeff kb2m I don't use DXLab. But have you ever tried it with SatPC32ISS? DXLab utilizes the SatPC32 DDE string. SatPC32ISS sends the same string (always or when the satellite is audible, takes that from SatPC32). Create a new sub folder SatPC32ISS in the SatPC32 program folder. Copy the two sub folders Maps2D and BM-Maps2D and SatPC32ISS.exe from the main folder into the new folder. Then rename SatPC32ISS.exe to SatPC32.exe. You can start it with a shortcut on the desktop. It should then appear to DXLab exactly like the normal SatPC32. 73s,Erich, DK1TB

RRe: Re: Transponder active CAS 10 (aka XW 4 (Hope 4))
by Pedro Converso 22 Dec '22

22 Dec '22

Hi, I do run ok tracking the birds on W10 downloading free http://amsat.org.ar/pass.exe and installing, besides downloading http://amsat.org.ar/wispdde.exe and installing/selecting as Orbitron, it's usefull to place both icons on desktop. On wispdde you can set rigs, rotor and ports either real RS-232 or bluetooth. Wispdde handles TS-2000 and many other rigs, as well as different rotors. Concurrently running both with administrator privilegies on W10, will control dopplers and rotor, many use that way succesfully for last years. What this provides is an easy and fast way to just click on any satellite in view to receive/operate, setting automatically rig freqs/dopplers/modes and rotor az/el, without any worry of loading keps, allowing watching on local time and detecting your location automatically. Additionally for reception only a generic USB SDR using HDSDR configured as Orbitron will do.

FO-118 H/U Mode
by Tony 21 Dec '22

21 Dec '22

All: The H/U mode on FO-118 seems to be working well. I noticed that the up-link is in the upper portion of the 15 meter band which seems a bit unusual since HF satellites in the past like RS-12/13 had up links that were much lower in the band i.e., 21.210 though 21.300 kHz. I wonder if there's been any changes in the rules regarding frequency allocations set aside for HF satellites. A quick glance of the FCC website doesn't show anything specific. Tony -K2MO

Changes to AMSAT-NA Mailman Message Delivery - FYI Only - No Action Required
by Matthew Alberti (KM4EXS) 20 Dec '22

20 Dec '22

AMSAT-BB, The AMSAT IT Team is aware of the inconsistent deliverability of AMSAT-BB e-mails. It affects several of our lists/reflectors. We see that some messages are only delivered to certain domains (ie. yahoo.com, but not gmail.com, etc.) It seems that this issue is more prevalent on lists with a lot of traffic, namely AMSAT-BB and ANS. This also seems to change randomly. We have been working on several solutions to try to improve deliverability. We are currently implementing one that is expected to resolve a lot of the issues noted. As a result of the changes, you may see that the "to" or "from" format of the e-mails may look different. However, the function of the lists are unchanged. You don't need to change anything on your end. This message will serve as the first test of the changes; and we hope to see that it is delivered far and wide. We will be monitoring for any indications that we have somehow made things worse. Rest assured, we will undo the changes if that seems to be the case. We appreciate everyone's patience, as we work to solve these complex problems. Feel free to always contact postmaster(a)amsat.org<mailto:postmaster@amsat.org> to register your e-mail related complaints. We also like to read when things work great and you are happy with the service(s). We are a very small (less than 5) person volunteer team, and we all have full-time jobs and families. We do our best. Thank you and Happy Holidays. ------------------------------------ Matthew Alberti / KM4EXS AMSAT-NA IT Team

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/ In this edition: * CAMSAT XW-4 (CAS-10) Scheduled for Deployment Today * CAS-5A Designated Fengtai-OSCAR 118 (FO-118) * Administration Drafting Executive Order To Simplify Space Rules * Top Ten Most Needed of the 488 Gridmaster Grids, November 2022 * Changes to AMSAT-NA TLE Distribution for December 8 * Spacewalk From ISS With Two Cosmonauts Cancelled * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over ANS-352 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2022 Dec 18 CAMSAT XW-4 (CAS-10) Scheduled for Deployment Today The CAMSAT XW-4 (CAS-10) satellite was launched into the Chinese Space Station on November 12, 2022 aboard China's Tianzhou-5 cargo spacecraft, and was launched by the Long March-7 Y6 launch vehicle from the Wenchang Launch Center in Hainan, China. It is currently planned that the XW-4 (CAS-10) satellite will be separated from the Chinese space station and enter operational orbit at 01:30 UTC on December 18, 2022. The functions of XW-4 (CAS-10) satellite include UHF CW telemetry beacon, GMSK telemetry data transmission, V/U mode linear transponder, a visible light band space camera. After the satellite completes the in-orbit test and works normally, the space camera photo download will be open to amateur radio enthusiasts all over the world. When the relevant remote control command is received by the satellite, the GMSK telemetry channel will be used to downlink the photo storage information and photo data, and the telemetry data will stop sending at that time. XW-4(CAS-10) satellite adopts a 8U CubeSat structure with a mass of about 12kg, an on-orbit envelope size of 1007x790x475mm with four solar array panels and a three-axis stabilized attitude control system is used, long-term power consumption is about 18.3 Watts. XW-4 Technical specifications are as follows: * CW telemetry beacon: Frequency: 435.575MHz RF power: 20dBm CW rate: 22wpm * GMSK telemetry: Frequency: 435.725MHz RF power: 23dBm Data rate: 4800bps * V/U mode linear transponder: Uplink frequency: 145.870MHz Downlink frequency: 435.180MHz RF power: 20dBm Bandwidth: 30kHz Spectrum inverted * Photo download remote control: Coming soon...

The order would be part of a push by the White House's National Space Council to modernize U.S. space regulation, which has failed to keep up with the increasingly ambitious pace of private-sector investment and development. The order, slated to be ready for Biden to sign by early 2023, is meant to simplify licensing procedures under existing laws for more routine space activities like launching rockets and deploying satellites [ANS thanks Reuters for the above information] --------------------------------------------------------------------- Top Ten Most Needed of the 488 Gridmaster Grids, November 2022 As of November, stations actively seeking the Gridmaster award who have reported their progress to KE0PBR -- owner of the Gridmaster Heat Map account on Twitter, and AMSAT rover page manager -- have indicated that the following are the most needed grids at this time: 1. CM79 2. DN35 3. DN08 4. CM89 5. DN27 6. DN24 7. DN26 8. DL79 9. DM86 10. DM76 Satellite operations or roves in any of these grids would be VERY popular!

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/ On December 9, 2022, CAMSAT's CAS-5A satellite was launched on a Smart Dragon-3 Y1 launch vehicle from the Chinese sea launch platform in the Yellow Sea. See AMSAT News Service Bulletin ANS-345 (Dated December 11, 2022) for transponder data. Then, at the request of CAMSAT and the CAS-5A team, AMSAT has designated the satellite as Fengtai-OSCAR 118 (FO-118) on December 15, 2022. See Drew Glasbrenner, KO4MA and OSCAR Number Administrator's bulletin (above)) for details. Originally FO-118 was thought to be NORAD Cat ID 54682, but more recent TLE have revealed that CAS 5A is actually object 54684 (2022-167C). Thanks to Nico Janssen, PA0DLO, for the update on the correct NORAD Cat ID for FO-118 (formally CAS-5A). Therefore, the following satellite has been added to this week's AMSAT-NA TLE distribution: FO-118 NORAD Cat ID 54684. [ANS thanks Ray Hoad, WA5QGD, AMSAT Orbital Elements Manager, for the above information] --------------------------------------------------------------------- Spacewalk From ISS With Two Cosmonauts Cancelled The Roscosmos Mission Control team in Moscow postponed Wednesday evening’s planned spacewalk with two cosmonauts to evaluate the situation and data from the Soyuz spacecraft. None of the crew members aboard the International Space Station were in danger, and all conducted normal operations throughout the day. Roscosmos is closely monitoring Soyuz spacecraft temperatures, which remain within acceptable limits. NASA and Roscosmos continue to coordinate external imagery and inspection plans to aid in evaluating the external leak location. Plans for an additional inspection of the Soyuz exterior using the station’s Canadarm2 robotic arm are underway. The leak was first detected around 7:45 p.m. EST Dec. 14 (0045z on Dec. 15) when data from multiple pressure sensors in the cooling loop showed low readings. At that time, cosmonauts Sergey Prokopyev and Dmitri Petelin were preparing to conduct a spacewalk. The cosmonauts did not exit the space station, and no crew members were exposed to the leaking coolant. The Soyuz MS-22 spacecraft carried NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin into space after launching from the Baikonur Cosmodrome in Kazakhstan on Sept. 21. [NOTE: All amateur radio equipment aboard the ISS is switched off during docking maneuvers and EVAs (spacewalks)] [ANS thanks NASA 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.

Kenwood TS-2000 - FalconSat-3
by Jim McCullers 12 Dec '22

12 Dec '22

Thanks to all that responded to my question concerning the Kenwood TS-2000 and 9k6 packet. Special thanks to Jean Marc (3B8DU) for his menu selection list. I was not setting menu item 56 correctly. Now I can see the data in the hs_soundmodem waterfall. Unfortunately I was not able to decode packets even with excellent passes which I believe is the result of an inadequate antenna setup and rain that was heavy at times. I'm in an area with a lot of foliage some of which are southern pine trees with needles that are natural attenuators at 70cm, especially when wet. Thanks again and we'll be back next weekend.

AMSAT NEWS SERVICE ANS-345 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/ In this edition: * CAMSAT's CAS-5A Satellite Launched, Transponders Active * AMSAT-DL Erminaz Mission Announced * VUCC Satellite Standings December 2022 * Changes to the AMSAT TLE Distribution for December 8, 2022 * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over ANS-345 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2022 Dec 11 CAMSAT's CAS-5A Satellite Launched, Transponders Active CAMSAT's CAS-5A satellite was launched at 06:35 UTC on December 9, 2022 into a 554 km x 543 km orbit with an inclination of 97.5 degrees. The satellite was launched on the inaugural flight of the Smart Dragon-3 Y1 launch vehicle. This vehicle launches from a sea launch platform in the Yellow Sea. CAS-5A carries two linear transponders and an FM transponder, which are all continuously active assuming the power budget permits. The frequencies are: V/u Linear Transponder: Uplink 145.805 MHz - 145.835 MHz, Downlink 435.525 MHz - 435.555 MHz (Inverting) V/u FM Transponder: Uplink 145.925 MHz, Downlink 435.600 MHz H/u Linear Transponder: Uplink 21.4275 MHz - 21.4425 MHz, Downlink 435.4975 MHz - 435.5125 MHz (Non-Inverting) CW Beacon: 435.570 MHz (22 wpm) Telemetry: 435.650 MHz (4800 bps GMSK) QSOs have been reported via all three of the transponders as of this writing. Reports indicate that the downlink is strong and the transponders are sensitive. Nico Janssen, PA0DLO, reports that Doppler measurements show CAS-5A to be object 54682 (2022-167A). However, he cautions that not all objects from the launch have been cataloged yet, so this identification is subject to change.

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/ The following satellites have been added to this week's AMSAT TLE distribution: Tevel-1 NORAD Cat ID 51013. Tevel-2 NORAD Cat ID 51069. Tevel-3 NORAD Cat ID 50988. Tevel-4 NORAD Cat ID 51063. Tevel-5 NORAD Cat ID 50998. Tevel-6 NORAD Cat ID 50999. Tevel-7 NORAD Cat ID 51062. Tevel-8 NORAD Cat ID 50989. (Thanks to N2YO for providing the NORAD Cat Id for the Tevel series of satellites.) The Israeli team operating these satellites is going to keep at least one of these eight satellites active all the time, so we will need TLE available for all eight of them. Tevel-3 was activated briefly last weekend. Thanks to Paul Stoetzer, N8HM, for the "heads up" on the status of the Tevel series of satellites. Note: The object named Tevel (NORAD Cat ID 50999) in past TLE data was simply a place marker for the Tevel series until the identity of this series of satellites was sorted out. Tevel-6 is the new name for the object NORAD Cat ID 50999.

All I added the CAS-5A elements (2022-167A) to the nasabare file for SATPC 32 and when I restarted the program I for this error message: ungutes argument zum codieren des datums, and now the program won't start past the error message. What did I do wrong and more important, how do I fix it? TIA Rick Tejera Saguaro Astronomy Club www.saguaroastro.org Thunderbird Amateur Radio Club www.w7tbc.org

CAS 5A identification
by Nico Janssen 10 Dec '22

10 Dec '22

Doppler measurements show that CAS 5A almost certainly is object 54682 (2022-167A). But some TLE sets for this launch are still missing. So it may change later. CW beacon frequency: 435.5700 MHz. 73, Nico PA0DLO

TQSL Support for IO-117
by Calvin McDonald 10 Dec '22

10 Dec '22

I'm getting a bit antsy waiting for the ARRL to update TQSL to support GreenCube(IO-117), I'm backed up over 100 QSO's now. Digging around a little tonight I see the satellite definitions are stored in TQSL's config.xml file. It would appear that adding a line in this file for IO-117 is all that would be needed to enable logging QSOs for this bird. My gut is telling me that doing so is over-simplifying what is needed to support IO-117, but thought I'd ask. Can a person just update the config.xml file? Why is the ARRL so slow at making this seeming simple update? N7AY

For those who would like to monitor some of the live telemetry parameters of Orion/ESM during the current Artemis 1 mission, see this page: https://hamsat1.home.xs4all.nl/Orion_tlm.txt Unfortunately the list of parameter descriptions is incomplete. Is there anyone with contacts at NASA JSC who can give us more information on these public telemetry parameters? Probably a similar public telemetry stream will be made available during the crewed Artemis 2 mission.
