Fw: AO73 Mode change
by Graham Shirville 11 Jun '19

11 Jun '19

Hi folks, AO73/FUNcube is now in amateur mode for the weekend with the transponder on! Please see below for all FUNcube mission info 73s Graham G3VZV and the FUNcube team. ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula… EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 – 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

Using 1.2Ghz
by Todd 04 Apr '18

04 Apr '18

Thinking about adding the 1.2Ghz module for my 9100. Prices have dropped a little and units will start become harder to find once production ends. Anybody using this band? I read it's used as a uplink frequency for some satellites. Any input appreciated.ToddAL7PX

Outernet L-Band now carries AMSAT and ARISS weekly bulletins
by Robert Bruninga 17 Mar '18

17 Mar '18

The Outernet L-band feed is now carrying a condensed version of the AMSAT and ARISS weekly news files. (Global Geosat coverage except for Northern Alaska)... Receivers are simple: http://aprs.org/outnet.html For ARISS, I manually added a 2 char grid square to each school listed in the school schedule and am asking the outernet folks to parse out that location info and plot a 1200 km footprint on their weather globe showing where people can tune in the ARISS contacts. Then their RTL-SDR dongle could then actually be retuned to hear the contact. Just an idea...

SATPC32 doppler correction stops working
by Gabriel - EA6VQ 31 Jul '17

31 Jul '17

After years on not being on the satellites I am trying to be active a little again. I have installed the trial version of SATPC32 12.8b in order to automatically correct Doppler in the rig and it works fine for 5 to 10 minutes, but then it stops updating the frequency in the transceiver. No error message or something, it just stops updating the frequency. Some information: - Rig is an IC-9100 - OS is Windows 10 64 bit - CAT is connected using the IC-9100 USB port (Silicon Labs CP210x USB to UART Bridge) Some tests I have already made and additional information: - The drivers I had for the CP201x were old. I have updated them with the latest, but without luck. - I have tried running SATPC32 as administrator, without changes. - When the Doppler correction fails, the CAT communication is still working. For instance I can change CW/SSB using the C+/C- button. - The only way to make it work again is to reconnect the IC-9100, so that the COM port is created again in Windows, and obviously restarting SATPC32. - Years ago I remember I tried version 12.8b , in Windows XP, and Doppler correction was working. - When I use the CAT communication in the same PC with the logbook program, there are no issues. Before you tell me that I should try version 12.8c, I have already done it and it is worse: for instance, it not even changes the frequencies in the rig when changing from one satellite to another, although CAT communication has been stablished. Anyone using SATPC32 on Windows 10 64 bit together with the IC-9100, with success? Any idea of what to try next? Is there some other program that I can use for Doppler correction? 73.

Upcoming ARISS contact with VCP-Bundeszeltplatz, Großzerlang, Germany
by n4csitwo＠bellsouth.net 31 Jul '17

31 Jul '17

An International Space Station school contact has been planned with participants at VCP-Bundeszeltplatz, Großzerlang, Germany on 01 Aug. The event is scheduled to begin at approximately 18:20 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and DP9S. The contact should be audible over Germany and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. The "Bund der Pfadfinderinnen und Pfadfinder"(BdP) is a Guide and Scout Association from Germany. BdP is part of the "World Organisation of the Scout Movement" (WOSM) and the "World Association of Girl Guides and Girl Scouts" (WAGGGS). Every four years a National Jamboree (summer camp) is organized, where about 5'500 guides and scouts, in the age of 12 to 16 years, meet. Part of this gathering are also about 500 guest scouts from all over the world.In German the camp is called "BuLa" - a abbreviation for "Bundeslager". During two weeks the scouts live peaceful together and enjoy life abroad from civilization. They camp in traditional "black tents", which are a specialty of German scouts. The basic tent shape it that of a small tipi (Kothe) our a yurt (Jurte). But there are nearly no limits in combining the tent elements and the scouts build awesome constructions, which they call yurt-castle (Jurtenburg). After everything is built, the campground becomes a little city, where the inhabitants experience a unique back-to-the-roots atmosphere and share thescouting and guiding spirit. The 10 main camp days are loaded with exciting outdoor activities.But there on site actives but also excursions to the surroundings. You can climb, build pioneering stuff, go geocaching, biking, hiking, climbing, swimming, canoeing, go for a drink or snack in on of the tent coffees, etc. etc. One activity spot is the scout-radio-amateur-tent. There the scouts can do amateur radio direction finding (fox hunting), play a game with avalanche beacons, have internationalamateur radio contacts, learn about EME (earth-moon-earth) and try it out or play one of the other radio connected games. And of course, a highlight of ours is the contact with the ISS. The motto of the camp is "Estonteco 2017". "Estonteco" means in Esperanto "future". Our tent city will be a space for different walks of life, nationalities and cultures, to engage and get know each other, while we build our camp world from scratch. Participants will ask as many of the following questions as time allows: 1. What are the current research projects that you have on board the ISS? Which experiment are you carrying out? 2. What skills do you need to become an astronaut and how do you acquire them? 3. What was the most important or most spectacular scientific discovery made on the ISS up to now? 4. What if somebody gets seriously sick? 5. What was your motivation to become an astronaut? 6. What was the most critical situation on the station so far? 7. Can you see our Jamboree site from space and could it help if we shine a laser pen towards the ISS? 8. How do the constellation of the stars change compared to the view from the Earth? 9. How often are you working outside in Space? Is it dangerous? 10. How do you shower in space? 11. Is it possible to see the romantic sunsets from the ISS like from the Earth? Or even polar lights? What about rainbows? 12. What happens, when a meteorite hits the space station? 13. How does the food taste? 14. When you are looking out of the window towards the Earth, do you sometimes think of the insignificance of humanity or of your own person? 15. What is the most annoying thing up there? 16. What are you most excited about, when you are back on Earth? 17. How do you experience the day-night-rhythm? 18. Do you have plants? 19. You've been away from home for a long time. How is that for you? 20. What do you miss most? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook.

AO73 Mode Change
by MrToby 31 Jul '17

31 Jul '17

Thanks for all of the details about Funcube operations. I'm new to Sats and have a question: what is the technical reason that Sats don't operate in eclipse (when the solar panels are illuminated?). That seems counter intuitive to me as the Sat would have more power. Thanks for the help. Marshall, AA0FO (em29)

Is 70cm an option for ISS packet this time?
by Scott 30 Jul '17

30 Jul '17

Greetings everyone. Since this most recent packet failure on the ISS, I have not heard any mention of switching back to 437.550 MHz. Is that not an option this time? Has it been established that some other component is at fault now, and the choice of radio would make no difference? Thanks! -Scott, K4KDR Montpelier, VA USA

AMSAT NEWS SERVICE ANS-211 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, 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. In this edition: * Packet Module Status On Board ISS * Oklahoma Radio Amateur is First to Score Satellite VUCC from Greenland * 437 MHz Sprite Satellites Deployed * QIKCOM-1 Team Expect Eclipse Day ISS Deployment * One Radio Amateur is Part of New Crew Increment Heading to ISS * Fox-1 Operating Guide Updates for 2017 * AMSAT Presentation at the Austin Summerfest, August 5, 2017 * ARISS News * Satellite Shorts From All Over SB SAT @ AMSAT $ANS-211.01 ANS-211 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 211.01 >From AMSAT HQ KENSINGTON, MD. DATE July 30, 2017 To All RADIO AMATEURS BID: $ANS-211.01 --------------------------------------------------------------------- Packet Module Status On Board ISS ARISS has received several reports stating that the packet system on ISS is down. Here is what we know and our current forward plan. The packet system in the Columbus module started to act up late last week, sending only a beacon. The ARISS team requested a power recycle by the crew, and with that power recycle, the packet system appears to have stop functioning completely. Note that this unit has been on- orbit for 17 years. It was launched on the STS-106 Space Shuttle Atlantis mission in September 2000 and was built, tested and certified for flight about 20 years ago. The ARISS team has had some extensive discussions on the way forward. We would first like to do some additional troubleshooting with the existing packet module. It will take some time (weeks) to develop troubleshooting procedures, get the procedures approved by NASA and then conduct the tests with the crew. This includes an additional power cycle. The turnaround time is much longer than usual because a new crew will soon be arriving on ISS. The current crew is focused on the new crew arrival and there will be about a one- to two-week transition after the new crew arrives. On the positive side, one aspect of our troubleshooting—a second power cycle—will occur automatically because ARISS is shut down during crew docking and turned on afterwards. However, there will be more to our troubleshooting than just the power cycle. We have some additional plans with alternative solutions, but those are currently being discussed and prioritized within the ARISS team. All solutions will require international ARISS team coordination, additional procedures and crew interaction. People who have carefully followed ISS operations know that crew time continues to evolve with the more extensive research that is occurring on-board. Suffice it to say, it will take longer than what it has taken in the past to work through this issue. The above information is to make sure that ARISS properly sets expectations on how long it will take to resolve this. At this point, expect a few months with no ARISS packet. As you all can see, deploying the Interoperable Radio system that is currently under development by ARISS has become even more critically important. The ARISS team is laser focused on getting that system developed and deployed. We are conducting a final design review with NASA on this system next week. But we cannot get to the finish line without your help. If you can, please consider a donation to the ARISS radio fund by clicking on the ARISS donate button on the ARISS web page (www.ariss.org) or the AMSAT web page (www.amsat.org). All donations, large and small are appreciated. On behalf of ARISS, we thank you for your sustained interest and support of our program. Sincerely, Frank H. Bauer, KA3HDO ARISS International Chair [ANS thanks ARISS and Frank, KA3HDO, AMSAT Vice President, Human Spaceflight for the above information] --------------------------------------------------------------------- Oklahoma Radio Amateur is First to Score Satellite VUCC from Greenland It took just 4 days — some of that time without much sleep — but ARRL member Gabe Zeifman, NJ7H/VE6NJH, of Oklahoma City recently became the first radio amateur to earn VUCC — working 100 grid squares — by satellite from Greenland. In fact, his is the first VUCC award of any kind from Greenland. A relatively new licensee, Zeifman, 22, has managed to activate more than 300 grid squares via satellite as well as nearly 20 DXCC entities. Apart from the operating accomplishment, Zeifman told ARRL, he was attempting to inspire newcomers. “I thought it could get more people interested in satellites in general — VUCC is very achievable for anyone — and could also get more people interested in roving,” said Zeifman, who began training this week to become an air traffic controller. “I was overwhelmed by the support I got; it was really astonishing the number of people that helped!” He said one operator activated eight grids for him, while others who don’t typically rove, visited at least one neighboring grid square to give him a new one. “It was really cool to see our community throughout the world come together to help in this goal,” he said. “I really first envisioned this idea when I realized I had nearly 70 grids confirmed from Iceland, and I thought ‘hmm, OX is an even better location, I bet it’s possible.’” Zeifman said he prefers the linear-transponder satellites such as FO- 29, rather than the FM satellites. He said he may one day get into HF more seriously, but, for now, he finds VHF/UHF/SHF “more fascinating.” He said the trip to Greenland, Iceland, and the Faroe Islands with his mother and his sister, was “fantastic,” although, he noted, “they may have sometimes been annoyed by my getting up at 3 AM or several times “Sometimes it was a very nice sunny day, and sometimes it was rainy, windy, and cold,” he recounted. “But, I was happy to operate in everything, and it paid off.” Zeifman, who said he enjoys visiting in “the north,” has been to Northwest Territories twice in the past couple of years, and is hoping for an ATC assignment in Alaska. “But now that I’m a ham, I’ve really developed a passion for operating satellites while all over the world,” he told ARRL. He said a goal still on the far horizon would be to complete a “reverse DXCC” on satellite — working the US on satellites from 100 DXCC entities. “I think it’s definitely achievable someday,” he added.

On June 23, 2017 six tiny satellites were sent into low-Earth orbit as secondary payloads on the Venta and Max Valier satellites that were launched on the Indian PSLV-C38 rocket. These six satellites are comparatively dainty, but punch far above their weight. Called “Sprites,” each is a 4-gram flake of circuit-board just 3.5 centimeters on a side, packing solar panels, computers, sensors and communications equipment into an area equal to a U.S. postage stamp. One Sprite apiece is attached to the outside of each mothership — the Latvian Venta satellite and the Italian Max Valier satellite, the latter of which also holds four additional Sprites awaiting deployment into space as wholly independent spacecraft. Radio telemetry from minuscule magnetometers and gyroscopes on the deployed Sprites would then be used to track the spacecraft as they shift, spin and tumble, to better understand their orbital dynamics. Signals on 437.325 MHz from at least one of the exterior-mounted Sprites have been received in California and New York.

An International Space Station school contact was successful with participants at ISS R&D conference, Washington, D.C. on 20 July. The event began at approximately 13:23 UTC. The contact was a telebridge between NA1SS and W6SRJ. See the video at: https://www.facebook.com/SpaceStationExplorers/videos/334464240317857/ The contact was very successful with 24 questions answered. Five astronauts were present during the contact. Frank Bauer KA3HDO, ARISS International Chairperson and AMSAT VP for Human Spaceflight, said of the event, "Great day [Thursday July 20] at the ISS R&D Conference. This was a very important contact with our sponsors---CASIS and NASA SCaN at the event and many of the CASIS senior leaders in attendance. It was great to see several members of the multi-generational astronaut team, that have supported ARISS for over 20 years now, on stage and giving their perspectives of their ARISS connections from space. This ARISS contact was conducted with Youth in Aviation Program students from the East Coast Chapter, Tuskegee Airmen, Inc. (ECCTAI) attending the ISS Research and Development conference as part of the conference’s STEM day. ECCTAI is one of the largest Tuskegee Airmen, Inc. chapters in United States and serves the Washington DC area. ECCTAI is dedicated to keeping alive the history, achievements, and importance of the original Tuskegee Airmen. The term, "Tuskegee Airmen," refers to the men and women, who were involved in the so- called "Tuskegee Experience", the World War II Army Air Corps program to train African Americans to fly and maintain combat aircraft. ECCTAI strives to increase understanding of the “Tuskegee Experience” by honoring the accomplishments and perpetuating the history of the men and women who participated in the “Tuskegee Experience” and to introduce young people to the world of aviation and space through its Youth in Aviation Program (YIAP). YIAP motivates and inspires America’s youth to strive for similar excellence of these earlier pioneers, exposing them to aviation and space careers (Level I), attending FAA ground school (Level II) and receiving aircraft flight instruction or interning at an FAA certified A&P (Airframe and Powerplant) facility (Level III).

News of the award was heralded around the world by a message transmitted by the FunCube 1 satellite congratulating the group on their award. FunCube 1 was built by members of the Amateur Radio community and launched into orbit on 21st November 2013. It was built with the goal of enthusing and educating young people about radio, space, physics and electronics, and is the first satellite with outreach as its primary mission and demonstrates the depth and breadth of the hobby of Amateur Radio. The Bittern DXers' own Educational Outreach Project aims to take advantage of technology like FunCube to bring demonstrations of as many aspects as possible of their hobby to public events in Norfolk as well as reaching out to young people in schools, scouting and guiding etc. With the money provided by National Lottery players, the group have purchased gazebos, radios and demonstration equipment allowing them to take a complete hi-tech station to public shows and events that enables conversations with other amateurs around the world, as well as pick up signals live from the International Space Station, weather satellites and the many other amateur satellites currently in space. Chairman, Steve Cordner - callsign M0HET, said: “We are immensely grateful to the Big Lottery Fund and National Lottery players, for allowing us the opportunity to introduce amateur radio to people and show them what we do. “We already know for example that when young people are shown images being received live from space, that their imagination is fired up and they want to find out more. For older people it can break down barriers of loneliness and disability and allow them to communicate with others across county, country and world. “Becoming a Radio Amateur makes one more employable as well as leading to a lifetime of personal growth in the field of electronics and radio communication. Many people holding senior roles in high-tech industries today owe their careers to an early interest in amateur radio. Our project aims to provide people of all ages that 'first contact' with Amateur Radio.” Club Secretary, Linda Leavold, who has been licensed for more than 30 years with her callsign G0AJJ, is proof that it is not just a male hobby! She remarked “Being a radio amateur gives one a great sense of personal achievement especially when you make that long distance contact with someone on another continent. And its something the whole family can get involved in.” Laughing she added “Even my husband Richard joined me on the air after a couple of years! He got fed up with burnt offerings for meals and decided to discover just what it was that was occupying my time. “It doesn't matter where you come from, whether you have any disabilities or what age you are, Amateur Radio has something to offer everyone and we want to get out there and show people what they are missing.” Although they have a very busy calendar already this year, they welcome contact from any person or organisation who might be interested in seeing what they do. The contact details are available on www.bittern-dxers.org.uk [ANS thanks Julian, M0NUX for the above information] NASA Ground Station for Voyager 2 YouTube tour of Deep Space Tracking Station in Austrailia. https://www.youtube.com/watch?v=1rCrfQUcXDI [ANS thanks Zach, N0ZGO for the above information] --------------------------------------------------------------------- /EX In addition to regular membership, AMSAT offers membership in the President's Club.

I got this off another reflector. Even if you miss the deadline to purchase the lifetime senior pass at $10, it will still be a bargain at $80 later. If you go in person, it is $10, I chose to purchase mine online and save the drive. There was a $10 processing fee, still making it a bargain. 73...bruce For those of us over 62 and U.S. Citizens or Permanent Residents, or know someone who is: If you have lifetime Golden Eagle or Senior Pass, you are good. If you do not, you can still get a Lifetime Senior Interagency Pass for $10. That price is only good through August 27th, after which it goes to $80. Even the annual senior pass is going up to $20. These passes are basically good for Forest Service, and Parks Service facilities, nationwide, and covers Day Use fees. It gets you a discount on other fees, but not necessarily at the concessions. You can check it out and order online: https://www.fs.fed.us/visit/passes-permits/recreation-fees-passes A small investment if you are over 62 and don't have a lifetime pass. -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2018 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

D-SAT RX Opportunity over U.S.
by Scott 28 Jul '17

28 Jul '17

Hi everyone. Today I was included on an email from Alessio, IU5CRE, who is part of the D-SAT project team. (https://www.dsat.space/radiohams) Previously, it appears that the majority of the transmissions from D-SAT occurred when the satellite was over Europe. Alessio indicated in today's email that commands have been uploaded to D-SAT that may result in transmissions tonight over the U.S. around the UHF downlink of 437.505. He specifically mentioned 437.503 & 437.509. First, here are the approximate UTC times when D-SAT will be over parts of the U.S. tonight (UTC date: 28-July-2017): East - 0152 utc Central - 0326 utc West - 0500 utc If D-SAT is not in your tracking software, here is a web-based tracking site: http://www.n2yo.com/satellite/?s=42794#results And as always, there is good info on the DK3WN site at: http://www.dk3wn.info/p/?page_id=29535 -and- http://www.dk3wn.info/p/?cat=439 So I don't know what, if any, data we might see tonight but since this could be a limited opportunity on this side of the world, I wanted to share what I knew with anyone on this mailing list that shares my interest in cubesat telemetry. -Scott, K4KDR

INTERMITTANT DOWNLINK HEARD - CAS-4A transponder freq
by christy hunter 27 Jul '17

27 Jul '17

to All, this is to confirm my status report on the website, (in case you think it was a mistake) on July 27 2017, at about 0047UTC I could hear my downlink, although intermittently, during a pass of CAS-4A (using the published frequencies). The downlink had good audio (loud and clear), and I could only hear a few words of my transmission at a time. I was able to sustain for only a portion of the pass. Using 5Watts into a M2 16 el cross element circular beam. (436CP16). This pass did NOT coincide with any of the XW sats. 73, Christy KB6LTY, DM14 --- This email has been checked for viruses by AVG. http://www.avg.com

ARISS SSTV Pictures
by Cyprus Amateur Radio Society 26 Jul '17

26 Jul '17

Dear Sirs, Firstly thanks for the opportunity given to us all to receive the wonderful 20th anniversary pictures from the ISS over the last few days. I have prepared an article for one of the major newspapers in Cyprus and they are very excited to publish it. I have used one of the pictures I received from the ISS (3/12) as a sample for the article. However, the publisher has asked me if it is possible to provide a higher quality picture as the resolution received from the ISS transmission is very low for print purposes. I have searched on the Web, without much luck. Any chance you could forward me one of the transmitted pictures at higher resolution to use as an example together with the article? Many thanks! 73, Nestor Jacovides (5B4AHZ) President Cyprus Amateur Radio Society

ARISS News Release no. 17-10
by n4csitwo＠bellsouth.net 26 Jul '17

ARISS NEWS RELEASE no. 17-10 July 25, 2017 David Jordan, AA4KN ARISS PR aa4kn(a)amsat.org Packet Module status on board ISS ARISS has received several reports stating that the packet system on ISS is down. Here is what we know and our current forward plan. The packet system in the Columbus module started to act up late last week, sending only a beacon. The ARISS team requested a power recycle by the crew, and with that power recycle, the packet system appears to have stop functioning completely. Note that this unit has been on-orbit for 17 years. It was launched on the STS-106 Space Shuttle Atlantis mission in September 2000 and was built, tested and certified for flight about 20 years ago. The ARISS team has had some extensive discussions on the way forward. We would first like to do some additional troubleshooting with the existing packet module. It will take some time (weeks) to develop troubleshooting procedures, get the procedures approved by NASA and then conduct the tests with the crew. This includes an additional power cycle. The turnaround time is much longer than usual because a new crew will soon be arriving on ISS. The current crew is focused on the new crew arrival and there will be about a one- to two-week transition after the new crew arrives. On the positive side, one aspect of our troubleshooting-a second power cycle-will occur automatically because ARISS is shut down during crew docking and turned on afterwards. However, there will be more to our troubleshooting than just the power cycle. We have some additional plans with alternative solutions, but those are currently being discussed and prioritized within the ARISS team. All solutions will require international ARISS team coordination, additional procedures and crew interaction. People who have carefully followed ISS operations know that crew time continues to evolve with the more extensive research that is occurring on-board. Suffice it to say, it will take longer than what it has taken in the past to work through this issue. The above information is to make sure that ARISS properly sets expectations on how long it will take to resolve this. At this point, expect a few months with no ARISS packet. As you all can see, deploying the Interoperable Radio system that is currently under development by ARISS has become even more critically important. The ARISS team is laser focused on getting that system developed and deployed. We are conducting a final design review with NASA on this system next week. But we cannot get to the finish line without your help. If you can, please consider a donation to the ARISS radio fund by clicking on the ARISS donate button on the ARISS web page (www.ariss.org) or the AMSAT web page (www.amsat.org).

1/4 wave stub lesson learned.
by Robert Bruninga 26 Jul '17

26 Jul '17

1/4 Wave stub lesson learned. I always wondered exacly where one measured a ¼ wave coax stub.. the shield, or the total connection length to the center coax? ANSWER: The length of the center wire makes a difference. We had poor second harmonics from our Cubesat VHF transmitter. Carefully built a prototype shorted ¼ wave stub and tweaked it to over 26 dB of a notch at the second harmonic. But then to install it on the cubesat transmitter board, we couldn’t quite get the prototype coax to fit right at the transmitter connection and had to extend the center of the coax about 1/8”. This detuned the stub by over 5 MHz at the 145 MHz operating frequency though the length of the shield remained the same. Now I know. Everything counts! Fortunately it detuned it lower so I have two more cuts available on the flight unit to bring it in… Bob, WB4APR

New APRS Satellite to be deployed from ISS on 21 Aug
by Robert Bruninga 24 Jul '17

24 Jul '17

PRESS RELEASE: The QIKCOM-1 module containing an APRS transponder and Terrestrial Alert beacon will be deployed from the ISS on 21 Aug 2017. http://aprs.org/qikcom-1.html Built as a student project Amateur Satellite module at the Naval Academy, and attached to the NovaWurks SIMPL spacecraft, it will function identical to the ISS transponder on 145.825 with the same ARISS alias and once they widely separate, will permit possible dual-hop experiments between it and the ISS APRS digipeater. See page. A second experiment is a terrestrial alert beacon on the North American continent APRS frequency of 144.39*. This beacon can alert mobile operators doing normal APRS activities that the spacecraft is in view and that they can QSY to the space frequency of 145.825 for a quick satellite operation. A European beacon was also planned, but is disabled due to lack of consensus, and only the two A/B frequencies were possible in the hardware. This unconventional operation was coordinated in 2014 prior to the IARU change in policy in 2016 that will no longer coordinate such out-of-subband operations. The module and host SIMPL spacecraft have been on the ISS since December 2015, but not deployed due to a SNAFU with the FCC. Although this is the date of the Great North American Solar Eclipse, as far as we know at this time, this scheduled deployment has nothing to do with the Eclipse. But tens of thousands of hams will be out in the field that day to observe the eclipse, so remember to bring your APRS HT with you and listen for QIKCOM-1. (Release time is unknown at this time). It is 4 Watts and should be hearable on an HT. Bob Bruninga, WB4APR and Todd Bruner, WB1HAI control operator. * As everyone knows, the terrestrial 144.39 frequency is wall-to-wall packets in most populated areas and the chance of hearing the QIKCOM-1 module is small, but remember, those people who are driving in remote areas who are NOT hearing wall-to-wall packets, will have a high probability of seeing the beacon. And it is these remote travelers, far from the terrestrial network that are the ones that might need a satellite to get their message out!

D-SAT Mission
by IU5CRE 24 Jul '17

24 Jul '17

Dear Sirs, my name is Alessio Fanfani; I'm a young telecommunication engineer and an enthusiastic Italian satellite amateur (callsign IU5CRE). Three years ago I started to work with D-Orbit, an Italian aerospace company, on an ambitious CubeSat mission called D-SAT. D-Sat is a three-unit CubeSat designed, built, and operated by D-Orbit and it will be the first satellite in history that will come back into Earth's atmosphere in a safe and controlled way by means of a dedicated solid rocket motor and burn up instead of becoming new debris. D-SAT was launched on June 23th, 2017 into a 500 km sun-synchronous orbit from Indian SHAR. D-SAT is now fully operative in orbit and it is hosting three communication experiments in collaboration with an Italian university, high-level schools and a local hamradio community. For more information on D-SAT, you can visit the mission's website (www.dsat.space), where you will also find a page entirely dedicated to radiohams (www.dsat.space/radiohams) where you can download the software necessary for the reception of D-Sat's signal. We really hope you will consider joining us! Also, should you have any question about the mission, don't hesitate to ask! Thank you for your time and consideration. Sincerely, Alessio Fanfani, IU5CRE

After checking the EL meter by 'in parallel' connecting another meter (audio type) across the connections noted that this parallel meter was moving / doing ok. Surprised to see that the unit AZ meter now worked again !!! All well now and running as before. Exact origin still rather unknown though but all is working again !

ARISS NEWS RELEASE no. 17-09 July 8, 2017 David Jordan, AA4KN ARISS PR aa4kn(a)amsat.org ARISS Celebrates it's 20th Anniversary through SSTV Event In commemoration of the 20th Anniversary of ARISS, a Slow Scan Television (SSTV) event is planned for Thursday, July 20 starting around 21:25 UTC. The event plans to feature images from ARISS activities both past and present. This opportunity should cover most of the world during the operation period. The event plans to use a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the ham radio, specifically the onboard Kenwood TM D710 transceiver. Those receiving the images can post them at https://ariss-sstv.blogspot.com/ for viewing by the public. The 20 year history of ARISS will be displayed through a collection of 12 unique images sharing the amazing accomplishments of ARISS over the last two decades. SSTV signals will be sent to earth at 145.80 MHz using FM. The SSTV mode of transmission is expected to be PD 120 (PD 180 may be a second option). The event is expected to continue over a two day period. Since it's inception, Amateur Radio on the International Space Station (ARISS) has provided students an opportunity, through ham radio, to engage in conversation with orbiting astronauts and inspired many to seek careers in science, technology, engineering and math. Consider how you might inspire students in your area through this chance to capture images directly from space to their computers. Please note that the event, and any ARISS event, is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. While preparations are being finalized please check for new and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB(a)amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status for the latest information on this event. 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 Center for the Advancement of Science in Space (CASIS) and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies and amateur radio.
