Howdy gang, I copied cw beacon from a satellite on 437.325 just before the ISS AOS 03222021 0212Z TA1KI ITUPSAT1. I looked it up and discovered their webpage link is broken. It was launched in 2009 with 6 month life according to Wikipedia. Does anyone know where I can report this information ? Bill K7MT DN46 Helena, Mt

ARISS anticipates that the contact would be held between January 1, 2022 and June 30, 2022. 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 deadline to submit a proposal is March 31st, 2021. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on February 25th, 2021 at 8 PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-spring-2021.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.

Means works better at low power received?, or needs more > power to transmit?? For a given BER and a given noise power, GMSK will require more signal power as compared to BPSK. However, the GMSK signal, when viewed in the frequency domain, will have a narrower bandwidth than the BPSK signal. A completely AWGN (additive white Gaussian noise) system is assumed here, as there isn't much in space to produce significant multi-path fading. (This is also why the JTxx and WSPR multi-tone systems are not at all energy efficient for VHF+ space communications, while they excel at ionospheric bounce on HF.) --- Zach N0ZGO

ARISS is the groupthat puts together special amateur radio contacts between students around theglobe and crew members with ham radio licenses on the International Space Station (ISS). This will be a telebridge contact via amateur radio and students will take turnsasking their questions of Astronaut Shannon Walker, amateurradio call sign KD5DXB. Englishis the language that will be used for this contact. The downlink frequency for this contact is145.800 MHz. ARISSteam member David Payne, using call sign NA7V in Portland, OR will serve as therelay amateur radio station. The ARISS radio contact isscheduled for March 24, 2021 at 6:21 pm ACDT (Salisbury), (07:51 UTC, 3:51 am EDT, 2:51am CDT, 1:51 am MDT and, 12:51 am PDT). The School ofInformation Technology & Mathematical Sciences, Southern Hemisphere SpaceStudies Program is a large (765 students) R-7 primary school located in aMawson Lakes suburb in the City of Salisbury. The school’s Space StudiesProgram is jointly organizedby the International Space University and the University of South Australia. It is a unique, five-week live-inexperience focusing on an international, intercultural and interdisciplinaryeducational philosophy. In addition, the school’s STEM program (including the AdvancedTechnology Program) incorporates space-related studies that include theirISS-astronaut project, offering students a chance to understand how the ISSfunctions, how astronauts live and work in space, and student activities thatinvestigate small satellites using the CubeSat classroom kit through HEPTA (Hands-on Education Program for Technical Advancement).HEPTA is a hands-on study with intensive practical lessons of small satellitedesign and engineering. The hands-on activity focuses on establishing theknowledge of systems engineering by going through the whole process of systemintegration. The public is invited to watch the live stream at: tinyurl.com/ISSLinkup2021 _____________________________ Astime allows, students will ask these questions: 1.What do you do to entertain yourself in such a small space for a long time withso few people? 2.Do you have travel sickness or feel suffocated while you are in there? 3.How do you protect against radiation on the ISS? 4.Have you seen any suspicious activity (like extraterrestrial creatures)? 5.Are there any health risks when you are in outer space? 6.How long do you think that it would take to discover another universe? 7.Does space debris affect the ISS? 8.When Is space radiation more harmful to astronauts? 9.Is the possibility of a fire on the ISS more terrifying when you are on the ISSor when you are training and preparing to be on the ISS. 10.How long can the present International Space Station (ISS) be used for? 11.What are the benefits of exercising in space? 12.What is your workout routine? 13.How does it smell in there? 14.What does it feel like in microgravity, especially when brushing teeth or hairor even having a shower? 15.What inspired you to be an astronaut? 16.Can you tell us some more information about the ISS? 17.Does warp speed exist? 18.What simple tasks on Earth requires the most work in space – and what, otherthan floating, can be done easily in space but is difficult on Earth. 19. While in the ISS if someone gets sick, willnormal earth medicine work in micro gravity? 20.Have you done any Covid-19 related research on ISS? 21. Can we see the far side of the Moon from ISS?Or will we be able to see it from the new planned station orbiting near themoon? 22.How do you get rid of the smell in the space station 23.How serious is the problem of space debris and what is being done about it?

Contacts with N6DNM from CM79 Mar 20-21
by Dmitry Mizin 22 Mar '21

22 Mar '21

Hello again, Was great catching a lot of you from this rare grid. Rare due to challenging conditions. One of those is the signal attenuation due to thick evergreen vegetation. Unfortunately this translates into some issues with audio recordings and decoding - a very weak signal my recorder really struggled with. I know I have missed in logging a few contacts because of a faint signal. Still going though those a few more times trying to isolate calls. However, if you do not see our contact logged in LOTW (all that I could decipher have been uploaded) and know we had it - please send directly to me pass details and I will concentrate on listening for it. Better yet, if you have a recording as well - please provide as it will help tremendously. This is a very rare grid and I would hate to see it being lost for you because of my (i guess) subpar recorder. Just for information - one I use is Sony PX-333 MP3 recorder. It does ok under normal conditions, but MP3 recording of faint signals just doesn't cut it. Thanks for all the contacts and will catch you from the next one! Dmitry N6DNM

FUNcube1 Transponder Status
by David Johnson 22 Mar '21

22 Mar '21

Hi, The FUNcube team put FUNcube-1 (AO-73) into full time high power Telemetry mode on 9th March, to test out the response of the Battery and PA temperatures as the satellite starts to enter an eclipse period. This has thrown up some interesting thermal responses within the satellite (nothing threatening). The battery temps have gone down in response to the PA consuming / dissipating more energy. We will be reviewing the move back to transponder mode in the next few days and will publish the timeline here and on other social media channels. As always we should like to express out thanks to all those who capture data packets and upload them to the data warehouse: http://data.funcube.org.uk/ui/fc1-fm 73 Dave, G4DPZ on behalf of the FUNcube Team
