This year it will be incorporated into the RSGB Convention at the Kents Hill Park Convention Centre in Milton Keynes. Exact details are currently being finalized with the RSGB and these will be notified when they are known. If you have not been to Kents Hill before, it is very close to the M1 motorway and is near to Bletchley Park, where RSGB members have free entry. For overseas visitors it is convenient for planes to London Luton Airport (30-minute taxi ride) and also London Gatwick and Birmingham airports, both of which have direct train connections to Bletchley and/or Milton Keynes stations. These stations are approximately 10 minutes away by taxi. [ANS thanks Jim Heck, G3WGM for the above information] --------------------------------------------------------------------- ITF-2 CubeSat Set to Deploy from ISS Toshihiro Kameda, JJ3GRX/W3GRX, of the University of Tsukuba's "Yui" satellite project in Japan, reports that the ITF-2 ("Imagine The Future") CubeSat is set for release from the International Space Station (ISS) on Monday, January 16, at 0910 UTC. The 1U ITF-2 was designed and built at the university. The Amateur Radio downlink is 437.525 MHz. Updated information will be announced on the AMSAT Bulletin Board at, http://www.amsat.org/pipermail/amsat-bb/ . ITF-2 is the successor to the unsuccessful ITF-1, which launched in 2014 but was never heard. Six CubeSats delivered to ISS by HTV-6 will deploy from ISS with new JEM Small Satellite Orbital Deployer (J-SSOD) at 16h Jan. New J-SSOD has four satellite install cases. One satellite install case has 3U space, so new J-SSOD can delploy twelve CubeSat at one time.

Live broadcast will start at 0850z on YouTube JAXA channel. https://www.youtube.com/watch?v=R4xq_rj0QiQ [ANS thanks the ARRL and JAXA for the above information] --------------------------------------------------------------------- Satellite Logging Updates Requested for ARRL LoTW AMSAT has requested that BY70-1 be added as "BY70-1" in the next configuration file for the ARRL Logbook of the World (LoTW). AMSAT has also requested that this update be made no later than January 31st due to NPOTA QSOs that were made via the satellite. AMSAT has also requested the addition of IO-86 as well as SAREX and MIREX for previous QSOs that occurred via the digipeater carried on various Space Shuttle missions and the Mir space station. If anyone notices a satellite that was available for amateur operation that is not included in the LoTW configuration file, please let me know: Paul Stoetzer n8hm(a)arrl.net Please also keep in mind that there may be a delay in requests being made for the addition of satellites to the LoTW configuration file while AMSAT awaits word of any potential OSCAR number request. [ANS thanks Paul Stoetzer, N8HM, for the above information] --------------------------------------------------------------------- College OSCAR Activity, Grow Future Membership In 2008-2009 we used to have regular College Satellite Nights, where clubs active in our area of interest would get on the birds at the same time and give out contacts. Please let me know if there is an interest again in doing this once per month and if the group minds allowing SO-50 to be the venue. It is important to our future that we grow our ranks through attracting younger hams. OSCAR operating at the college level can also be a huge advantage for attractive college students to the hobby. Many of our technician course attendees at UF are there for that reason (we give two licensing courses a year). Please help spread the word to those at your local universities, and to other college clubs. There will be a College Student Amateur Radio Forum at HamCation HamFest in Orlando, Saturday Feb. 11. Please let college student hams know of the event info. The event is ARRL sponsored, part of CARI, the Collegiate Amateur Radio Initiative. The forum will take place at 3pm, and there is room for 50 college student attendees. There are more events planned for the day, including an evening social event for college students. We should also have table space for the day for college clubs to distribute club info and to meet, greet, and network with alumni. The table would be a good place for high school student hams to network in preparation for a life of amateur radio during the upcoming college years. Questions can be directed to the moderator of the forum, UF Doctoral student Andy Milluzzi, KK4KWR - andy(a)gatorradio.org For the latest of information see the CARI Facebook group - https://www.facebook.com/groups/ARRLCARI/ [ANS thanks Dr. Jay H.

Upcoming ARISS contact with High School "Léon Blum", Le Creusot, France
by David H Jordan 15 Jan '17

15 Jan '17

An International Space Station school contact has been planned with participants at High School "Léon Blum", Le Creusot, France on 16 Jan. The event is scheduled to begin at approximately 11:53 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and K6DUE. The contact should be audible over the east coast of the U.S. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Le Creusot is a commune in the Saône-et-Loire department in the region of Bourgogne in eastern France. Formerly a mining town, its economy is now dominated by large metallurgical companies such as ArcelorMittal, Schneider Electric, and Alstom. In the 19th century, iron ore mines and forges around Le Creusot generated a business in steel, railways, armaments, and shipbuilding. The lycée Léon Blum (Le Creusot-71) together with the lycée international Charles de Gaulle (Dijon-21) and lycée Pierre Paul Riquet (Saint-Orens-31) were selected after a call for projects in March 2015 by the CNES Youth Education department for the PROXIMA mission. The project is named CERES (after the name of ancient roman goddess of agriculture) Thomas will grow some seeds in space as part of the CERES educational experiment. A special cargo of mustard, lentil and radish seeds was sent to him on the Space Station. He should water them and take pictures at regular intervals to study how the seeds grow in space. Students of the two partner high schools and a local elementary school are also participating to the list of questions. Participants will ask as many of the following questions as time allows: 1. On imagine la vie dans l'espace très différente de celle sur Terre. Malgré les liaisons radios, vous sentez-vous coupé de la réalité? 2. Qu’avez-vous ressenti pendant votre sortie extravéhiculaire? Avez-vous eu peur du vide? 3. Constatez-vous quelques changements corporels? Par exemple la croissance accélérée des poils, des cheveux ou des ongles, ou à l'inverse une déshydratation de la peau, perte de cheveux, etc...? 4. Y aurait-il une différence de ressenti si la station elle-même n’était plus en chute libre mais en réelle apesanteur, éloignée de toute source de gravité? 5. Avez vous déjà réalisé notre expérience CERES sur la croissance des plantules? sinon quelles hypotheses ou conclusions pouvez vous déjà faire? 6. Serait-il possible d’entretenir des cultures ou développer un jardin dans l’ISS afin de subvenir à une partie des besoins nutritionnels des astronautes? 7. Pensez- vous qu'il soit possible de faire pousser dans l'espace des végétaux dont la plus grande partie est ici enfouie sous terre comme les carottes par exemple? et des végétaux plus grands comme des arbustes? 8. Que pensez-vous de la participation et l'implication de lycéens à des expériences menées dans l'espace? 9. Pensez-vous que des expériences comme CERES pourraient être réalisées sur Mars et permettre dans les années à venir d'éventuelles cultures sur cette planète pour une future colonisation? 10. Le fait de rester plusieurs mois dans une même station avec cinq coéquipiers ne crée-t-il pas parfois des conflits à cause du stress? 11. Sur Terre, l'homme est un géant de la découverte, de la technologie et du progrès. Mais, au milieu de l'univers, comment se sent-on? 12. Les particules dues aux pluies d'étoiles filantes ont-elles des conséquences (même minimes) sur l'ISS ou peut-être même sur vous, astronautes? 13. Quelles différences observez-vous entre les expériences réalisées sur Terre et dans l'Espace? 14. Comment vous organisez vous dans l’ISS avec les autres astronautes? Existe-t-il un roulement pour les différents services, comme la préparation des repas, etc... 15. Pouvez-vous vous vêtir comme vous le souhaitez dans la station spatiale internationale? Avez-vous la possibilité de laver votre linge dans l’ISS? 16. Pensez-vous au retour sur Terre? Si oui, appréhendez-vous cet instant? 17. Les astronautes suivent-ils (ensembles) toutes les traditions et fêtes de leur pays d'origine? (par exemple Noël le 25 décembre pour les Européens et Américains et le 7 janvier pour les Russes) 18. J’ai toujours rêvé d’être astronaute. Quels conseils me donneriez-vous? 19. Allez-vous réaliser des expériences dans l'ISS dans le but d’installer la vie sur Mars? 20. Pensez-vous que votre génération d'astronautes ira sur Mars? Espérez- vous y aller vous-même? Translated: 1. Life in space is thought to be very different from life on Earth. In spite of radio connections, do you ever feel you are cut off from reality? 2. How did you feel during your Extra-Vehicular-Activity? Did you fear the void? 3. What sort of body changes can you notice on you? For instance, did you notice any accelerated growth or loss phenomena concerning your hairs, hair, nails or even any form of dehydration? 4. Would you feel different sensations if the Space Station was not continuously falling around Earth, but really away from any source of gravity? 5. Did you already start our CERES experiment about seed germination? What difficulties did you meet? Otherwise what hypothesis could you make on its potential results? 6. Would it be possible to grow crops or develop a garden on the ISS in order to partially feed astronauts? 7. Do you think it’s realistic to grow vegetables in space, considering that their major parts are buried in the soil here on earth, such as carrots for instance? What about bigger size plants like trees? 8. How do you feel about the fact that high schoolers take part in and get involved into space experiments? 9. Do you think that experiments like CERES could be made on Mars and enable potential cultivation on that planet in the years to come to pave the way for a future colonization? 10. You are living with five other astronauts in the same station for several months: Could it be source of tension because of stress? 11. Here on Earth, human beings are witnessing major scientific discoveries and huge technological progress. However, how do we feel in the middle of the universe? 12. Do the particles triggered by meteor showers have some consequences – even tiny ones – on the ISS or maybe even on you as an astronaut? 13. What differences can you make between experiments that are being carried out on Earth and those in space? 14. How do you schedule activities with the other astronauts? Do you take turns to work on different tasks, like preparing meals? 15. Can you dress as you want on the ISS? Can you wash your clothes there? 16. Do you have in mind the moment you will come back on Earth? If so, do you feel concerned about that moment? 17. Do the astronauts share together all the traditions and celebrations of their own countries? Christmas for instance, which is celebrated on December 25th in Europe and America but on January 7th in Russia? 18. I have always dreamt of being an astronaut. Any helpful piece of advice? 19. Are you going to make experiments in the ISS in order to settle life on Mars? 20. Do you think that your current generation of astronauts will go on Mars? Is that your personal hope?

To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD 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 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.

FW: NO084 PSAT Spin Rate over 10 RPM (BRICSAT listening?)
by Robert Bruninga 14 Jan '17

14 Jan '17

Thanks everyone! Here is the question. Did anyone ever happen to hear anything on 435.350 during the last week that did *not* correlate with PSAT? It may have been BRICSAT in full sun! Its PSK31 trasnponder is on the same downlink... and since its only problem was poor power budget, it may have been alive and no one was listening? It all started Friday afternoon, when I happened to tune to PSAT and heard only about 10 seconds at the tail end of a pass and saw about a 5 second swoosh before the transponder dropped out. Giving me a complete guess at maybe 12 RPM. KO6TZ reported: a screen capture from Spectran of the "swoosh" fade lines from the 23:30utc pass of NO-84. The tick marks … are 1 second spacing… [with] just slightly over 5 secs between the fades. That puts the spin at ~11.7 RPM. And of course DK3WN nailed it with this high res plot: http://www.dk3wn.info/p/?p=76608 Showing 5 rotations in 32 seconds or about 9.4 RPM We had to use this signal strength method since the the telemetry spin data is of no practical use since it is undersampled. IE, we are only sampling at once every 5 seconds and so this is HALF the Nyquist rate. To capture a spin of 12 RPM we would need to sample over 24 times a minute. So that is why we needed people to simply listen for it and determine the spin that way. And it looks like today is the last day of full sun. We had gotten excited when we noticed this full sun late Friday afternoon and realized it would be a good time to listen for BRICSAT which also has an HF PSK31 downlink on 435.350. But we noticed that after 20 months in space, that BRICSAT has separated enough that it ended its full sun period the day before. Then we went and looked and noticed this full sun period for both satellites was only 5 days long anyway. We are embarrassed that we have not been watching the orbit and looking for these full sun periods. They may be rare indeed. Bob

Re: [amsat-bb] PSAT SPin Rate?

See here: http://www.dk3wn.info/p/?p=76608 73 MikeDK3WN -------- Ursprüngliche Nachricht --------Von: Robert Bruninga <bruninga(a)usna.edu> Datum: 13.01.17 22:00 (GMT+01:00) An: AMSAT <amsat-bb(a)amsat.org> Betreff: [amsat-bb] PSAT SPin Rate? We just noticed that PSAT is in full sun. We want to know its spin rate but seaman Murphy is visiting the shack rignt now… and our UHF seems to have an intermittent… Passes are in the afternoon approaching sunset (and of course in the morning around sunrise… that’s why its in full sun all the time, because its orbit is near the day/night terminator right now…) So, simply tune in 435.350 +/- 10 KHz doppler and listen to the SWISHES of the UHF FM downlink and count SWISHES per minute. SWISHES are the nulls you might hear in the UHF antenna pattern on an FM receiver. Hold your squelch open so you don’t get confused. It might be swishing at above 10 RPM which would be a swish every 6 seconds. Of course, if no one is transmitting PSK31 on 28.121 MHz then the PSK31 transponder might not be up…. So this is a good time to dust off the PSK31 Ten meter transmitter. Just transmit PSK31 in the 28.120 to 28.122 MHz passband and it should bring up the transponder.
