CAS-6 Beacon?
by Hasan al-Basri 23 Dec '19

23 Dec '19

Has anyone from Stateside heard TLM from CAS-6? (not expecting xponder on, just want to hear its heartbeat) I see a couple isolated reports from other areas of the world. There was no signal on the 5 deg EL earlier pass, and now waiting for teh 10;57 a.m. 16:57z pass with an EL of 64 deg here in central USA 73, N0AN I'm guessing that even the beacon may not be on while out of range of China 73, N0AN Hasan

Re: [amsat-bb] ANS-353 AMSAT News Service Special Bulletin - SMOG-P and ATL-1 Designated Magyar-OSCAR 105 (MO-105) and Magyar- OSCAR 106 (MO-106)
by Peter Horvath 22 Dec '19

22 Dec '19

Hello, on this happy occasion I'd like to add some more info about MO-105 and MO-106, hoping that more people will be tune in and listen to the telemetry received from the satellites. SMOG-P (MO-105) is a 1p PocketQube (5x5x5 cm, 250 grams), a fully redundant tiny satellite with an actual scientific payload: a flying spectrum analyzer. It measures the scattered RF energy over the UHF band (specifically, in the digital terrestrial TV band) that can be detected in space. ATL-1 (MO-106) is a larger 2p PocketQube featuring the same spectrum analyzer experiment. Both satellites transmit almost identical telemetry data. In addition to basic CW telemetry carrying callsign, battery voltage and temperature, there is a digital telemetry with variable data rate and coding scheme. Most frequently, modulation is 1250 or 5000 bps GMSK. The data is encoded either by the well-known "AO-40" FEC, or a shorter, proprietary variant of it, but they can also use a more powerful, state-of-art repeat-accumulate (RA) coding scheme. Some practical information about receiving the telemetry: A GUI telemetry receiver is available for Windows and Linux (soon for OS X as well), and a command line receiver can also be used (Linux only). Both can be downloaded from https://gnd.bme.hu:8080/index The programs are able to submit the received packets to the central telemetry data base. This requires a quick registration, the login credentials can be used with either of the decoders. There are some issues with the GUI software that hopefully will be resolved within a few days. These decoders assume either a USB receiver connected through the sound card or an rtl-sdr receiver. Thanks to Daniel Estevez, EA4GPZ, a high quality, full decoder and packet uploader is also available for GNU Radio 3.8 within the out-of-tree module gr-satellites. For uploading to the received packets, it uses the same login as the "official" programs do: https://github.com/daniestevez/gr-satellites/tree/maint-3.8 This decoder can unleash the full potential of the RA FEC. You'll need to put an FM demodulator in front of the flowgraph. I'd be glad to see many submissions on the "Leaderboard" from around the world: https://gnd.bme.hu:8080/leaderboard Having many receiving stations around the globe could greatly improve the global picture the spectrum analyzer payload can offer. 73 Peter HA5CQA/AK4RP

question on g5400 controller
by mikflathead＠aol.com 21 Dec '19

21 Dec '19

I am trying to help out someone with a controller. The control box works manually but does not work with his Sat32 controller. I am not familiar with the software but am trying to diagnose the control box. I am assuming a few volts on the DIN connector that correlate with the relay switching transistor should cycle the relays. If my thinking is correct how many volts would I apply to the DIN pins to prove out the controller is working correctly? Hope this makes some sense. Thanks Mike WB8PFZ

Message to US Educators Amateur Radio on the International Space Station Contact Opportunity Call for Proposals Upcoming Proposal Window is February 1, 2020 to March 31, 2020 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS is happy to announce a proposal window will open February 1, 2020 for contacts that would be held between January 1, 2021 and June 30, 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The proposal window for contacts between January 1, 2021 and June 30, 2021 will open on February 1, 2020 and close on March 31, 2020. Proposal information and documents can be found at www.ariss.org. Two ARISS Introductory Webinar sessions will be held on November 7, 2019. The first is at 6:00 PM ET and the second is at 9:00 PM ET. The same material will be covered during both sessions, so choose the session that best fits your schedule. The Eventbrite link to sign up is https://ariss-introductory-webinar-fall-2019.eventbrite.com . The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations' volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio. More Information For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org. Please direct any questions to ariss.us.education(a)gmail.com. 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.
