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.

Need Recommendation for SDR
by Frederick Herrmann 30 Nov '22

30 Nov '22

ALOHA! We are a small school in Kailua-Kona, Hawaii, far enough away from the volcanic eruption to be safe. We have an aerospace class and club that is upgrading a satellite ground station. We have: IC-705 Transceiver GPredict 50 Ohm System Computer with Windows 11 UHF & VHF Antennas (AMSAT combo) Yaesu Rotator Delta Fox Controller We expect to be monitoring and perhaps contacting satellites in LEO via UHF and VHF. We are looking for a recommendation for SDR. Previously, we have used the inexpensive RTL-SDR dongles, but with marginal success. We feel that it is really necessary to have an SDR with SDR# compatibility. We may also need one that can transmit, not only receive. Our nominal price range is under $500. We have been considering the following: Airspy R2 SDR SDRplay RSP1A HackRF 2021 PLUTO+ SDR AD9363 2T2R However, we would definitely consider any others. We would be grateful for any advice for anecdotes from experienced operators. Mahalo! Frederick Herrmann Makua Lani Christian Academy Kailua-Kona, Hawaii

Re: GreenCube(IO-117) Questions
by Fernando Ramirez 29 Nov '22

29 Nov '22

Hi Calvin! My setup is a Yaesu FT-897D, Signalink Audio Interface, ARR SP432VDG RF switched preamp and 7 element UHF Arrow II Antenna. I have noticed the same packets that you mentioned on question #1. They show up on the soundmodem but they are not decoded in the Greencube Client. I assume they are telemetry packets, malformed packets caused by signals clashing or packets not decoded even though they are loud and clear. As for power, I can make it with the max 20W that my radio puts out. Considering I am using an antenna with less gain than the usual tracked array, 100W with a high gain antenna is overkill. The satellite team is the one that switches the bird between 1200 or 300. 73 Fernando, KF7R

GreenCube(IO-117) Questions
by Calvin McDonald 29 Nov '22

29 Nov '22

GreenCube(IO-117) Fans, For reference I'm using: IC9700 SatPC32ISS-2 ERC-M Rotor Controller Yaesu G5500DC Rotor UZ7HO's soundmodem and GreenCube Digipeater (0.17) M2 436CP30 Yagi Dell Laptop running Win11 I have some questions for those working this bird: 1. Should every packet heard and seen in the waterfall decode to a message? I get a bunch that don't decode even when the RX signal is strong. Are some packets telemetry packets? I'm trying to determine if I have a RX issue or if this is normal. 2. I'm getting RX signal fading akin to tumble fading. I pretty much quit having this type of fading on all other birds when I upgraded to a circularly polarized antenna. GreenCube will fad out and back in about 6-10 times per pass (2ish minute cycle). Is this to be expected? Are others hearing this? 3. What transmit power is appropriate? On the horizon it seems fairly clear that running the IC9700 at full power isn't excessive but what about when the bird is closer to overhead. Is GreenCube like other birds and best to run at the minimum. It has been difficult for me to tell what I need to dial back to when overhead, if indeed I need to. 4. Why is the bird sometimes in 300bd mode and other times 1200bd? Who controls this? I find I prefer the 1200bd as the packets are shorter and present less time to be corrupted by something - like a doppler update. 5. I'm finding I TX better than I RX. I'm thinking I want a LNA at my antenna. Is anyone successfully doing this? Which LNA and can it be powered by the IC9700? Thanks all Cal - N7AY

28 Nov '22

What software is required to send and receive messages via the GreenCube sat. I’m currently running SatPC32 on Win 7. I have tried Uz7ho soundmodem . I can see and hear the signal on the waterfall but no decoding. Is there additional client software that i need to download or setup procedures or links i need to follow. Thanks for the help! 73 Larry K5DNA Sent from my iPhone
