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. A paper QSL will be sent to those who submit their transmissions.

(***) 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 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.

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.

I use mine mostly for satellite work and its designed to do this well. CAT control can be a bit touchy and most software which talks to it is pretty outdated by now.

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 2023-05-26 23:30 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 2023-05-26 23:30 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 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.

Realizing it's a 30 year old > radio & there are some documented issues with it, I'd like to hear from > anyone on the list who's owned and used one..the good, the bad & the ugly. Hello Robin, I have used my FT-847 for terrestrial VHF/UHF and satellite work, but not in more than a year or so now. I have not used it on HF. It also survived a lightning strike on the power line that seems to have hosed the speaker output (but not the headphones) -- I'll fix this someday. In general, I'm pleased with it. It is not an IF DSP rig like my IC-746Pro, nor is it a full SDR, but with the the 400 Hz CW crystal filter from INRAD (http://www.inrad.net/product.php?productid=158&cat=18), it works like a champ. It also has audio-stage DSP, which, when enabled, works wonderfully to clean up the post-IF crystal filter output. You'll likely want to put in a crystal reference heater. I have some bookmarks, but I'm not sure which one I used. Here's one that looks familiar: http://www.frenning.dk/OZ1PIF_HOMEPAGE/QH40A.htm Something I dislike: The RS-232 CAT control messages have no checksum (unlike Icom's CI-V), so any stray RF may/will cause the radio to interpret CAT messages from the PC incorrectly. This means it might change modes, bands, etc. during a QSO on the bird with Doppler tracking enabled. I've heard that the fix to this is to change out the RS-232 connector on the back with a USB dongle that uses a FTDI USB<->Serial chip. This means that all the serial CAT traffic is protected by the USB's CRC protection on the cable and the actual UART signals only travel on the PCB within the rig. Plugging a USB<->Serial adapter right into the back of the rig, skipping the intervening cable, might also solve the issue, but that depends on how well the USB serial adapter's electronics are shielded. This FAQ will come in handy, in general: https://www.supercontrol.de/cat/ft847faq/ft847faq.htm 73, --- Zach N0ZGO

I bought one of the first ones new....A solid radio. Only problem ever is the pots become noisy over time and I clean them with DeOxit....Not todays SDR type radio but a very good VHF/UHF radio....I have not used mine of HF but twine or twice...Diff RF outs a plus...I built a keying box for amps because keying for each band is brought out on a diff pin on the rear. Neat idea...The mod of replacing all band switching diodes with Schottky diodes is a plus...

TEVEL-3, 6 FM transponder activation
by david.greenberg＠bezeqint.net 26 May '23

26 May '23

Hello All, TEVEL-3, 6 FM transponders have been activated, starting from 26.05.23 18:35U for 72 hours. Downlink frequency = 436.400 MHz Uplink frequency = 145.970MHz NO PL tone. All Tevel sats transmit a telemetry beacon every 20 seconds. When the FM transponder is on beacons are off. The transponders are selected while we try to have minimal footprint overlapping ( TEVEL-1 and 8 are not functional). 73, David 4X1DG

RX-Only FT-817 for sale
by Barry Pfeil 25 May '23

25 May '23

Have you been wanting to pair up a second FT-817 as a downlink RX to go with your first 817/818? This radio has virtually no RF output but the RX works fine on all bands, HF/VHF/UHF. It is in EXCELLENT cosmetic condition, and includes all the original Yaesu accessories including the microphone (in case you want to repair the TX?), rubber-duck 2M/70CM antenna, shoulder strap, FBA-28 internal holder for eight AA cells, user manual and even the original shipping box.. It is equipped with a Powerpole adapter for the 12VDC input. I don't remember any FT-817 tuning knobs that are free-wheeling (spin under their own weight?) and this is no different but easily turns with two fingers. I'll ship anyplace in the U.S. for a price of $350. Let me know if you would like to see pix or have questions. email: barrypfeil(a)gmail.com text: 650 450 1053 Thanks ES 73, Barry K6RM

(***) Peggy Whitson John Shoffner KO4MJC Ali Alqarni 7Z1AJ Rayyanah Barnawi 7Z1RB 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 2023-05-25 16:3 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 2023-05-25 16:30 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 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.

About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ARISS Contact Applications (Europe, Africa and the Middle East) Schools and Youth organizations in Europe, Africa and the Middle East interested in setting up an ARISS radio contact with an astronaut on board the International Space Station are invited to submit an application from September to October and from February to April.
