Recording TX & RX from one or two radios?
by Ken M 21 May '18

21 May '18

Hello AMSATers, I'm looking to record both TX and RX audio to a digital recorder, either at the QTH or in the field (but mainly in the field), in either of two common scenarios: 1. TX from one radio, and RX from a different radio (as in satellite use with one radio for uplink and one for downlink). 2. TX/RX from the same radio (as in a full-duplex radio for FM satellites, or for non-satellite use). I'm wondering if you know of a device (or a published circuit design) that will allow TX/RX recording while isolating the radios from each other and/or a radio's TX from it's RX, while linked to the same recorder? I have to believe this is a well-solved problem within the satellite radio community but I haven't found too many ideas for field use. This is seems to be an easier problem to solve at the QTH if recording to computer, with various sound interfaces (Signalink, etc.) so my main interest is in field use with a digital recorder so I can record my QSO's while juggling two radios plus antenna, etc. The easy alternative is just to record the RX side, which is easy, and works for logging but doesn't give you the full exchange. Thanks & 73! Ken VA7KBM

1990 version of ARRL's Satellite Experimenter's Handbook, by K2UBC
by Philip Jenkins 21 May '18

21 May '18

I was looking through my ham radio bookshelves (yes, plural!) a few weeks ago, and I had nearly forgotten that I had this book...so I've been re-reading it. (No, I'm not interested in selling it.... <grin>) The history alone - details about the birds up to and including AO-13 - makes for fascinating reading, never mind the technical details for orbital considerations, tracking, and building satellites. Remember that this when AO-13 was only 2 years old, AO-7 hadn't been heard from in a few years, and FM birds were only a twinkle in some engineer's eye. If you can find this book, I highly recommend that you borrow/buy it - quite interesting to read what was going on in the satellite world 28 years ago! (I bought it in late 92/early 93 to read on the plane trip to VP2M for an AO-13 DXpedition.) Philip N4HF

Santa Rosa Island CM93 Grid Schedule
by Ron Bondy 21 May '18

21 May '18

I had a nice table in my earlier email with my current grid schedule for my Aug trip, but the ascii text got reformatted. I've entered the grid schedule on my qrz.com page and will update as the Aug date approaches. We have our ferry and campsite reservations for Santa Rosa so I don't see those dates changing. https://www.qrz.com/db/AD0DX Cheers, Ron, AD0DX

An International Space Station school contact has been planned with participants at Janusz Kusocinski Primary School No. 71, Poznan, Poland on 23 May. The event is scheduled to begin at approximately 11:06 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 W6SRJ. The contact should be audible over the west 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. Szko³a Podstawowa nr 71 im. Janusza Kusocinskiego in Poznan, Poland, is a 60-year old public primary school for students aged 6-15. Starting with the school year 2017/18, primary schools in Poland were extended from six to eight years so at present the school has 460 pupils in grades 1 to 7. The school is situated in the centre of one of Poland's greatest cities. A university, cultural and economic centre boasting a one thousand-year-old history, Poznan offers its inhabitants and visitors myriad educational opportunities of which the school takes full advantage. The school nurtures curiosity and creativity through an inspiring, broad and engaging curriculum. Thanks to a variety of educational programmes (e.g., Odyssey of the Mind, eTwinning, European Christmas Tree Decoration Exchange, etc.), the school offers its students opportunities for learning and development 'without borders' by which they will be enabled and empowered to attain their full potential and become competent in shaping their own future. The school puts great emphasis on STEAM activities. In the school year 2016/2017, the school piloted the 'Mission X. Train like an astronaut' educational programme in Poland and since then have been the centre for the programme in Poland. Despite their young age, the students attend lectures and workshops at best universities in Poland or give lectures at international student conferences. During the preparation period for the ARISS contact, the school cooperated with a local amateur radio club (SP3YOR) and plans have been made to establish an amateur radio club at school. The school takes part in various activities within the local community, cooperating with governmental institutions and NGO organisations. Szkola Podstawowa nr 71 im. Janusza Kusocinskiego in Poznan takes pride in its tradition of voluntary work. Every year, the school becomes the local Collection-Centre for Wielka Orkiestra Swiatecznej Pomocy (The Great Orchestra of Christmas Charity), the biggest, non-governmental, non-profit, charity organisation in Poland, which aims to support health care in Poland. Participants will ask as many of the following questions as time allows: 1. What was your path to becoming an astronaut? 2. What research conducted currently on the ISS has been specifically undertaken in preparation for the human exploration of destinations beyond low-Earth orbit? 3. If you had a chance to travel beyond our Solar System to find a new habitable planet for humans would you do it even if you knew you may never return to the Earth? 4. Does your being in space affect your general perspective on life? 5. What surprised you most in space? 6. What happens when you get ill on the ISS? 7.

21 May '18

An International Space Station school contact has been planned with participants at Viktor Rydberg Gymnasium, Stockholm, Sweden on 22 May. The event is scheduled to begin at approximately 08:53 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 west 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. A short history of Viktor Rydberg Gymnasium: In 1993 two mothers living in Djursholm were concerned about the education of their children. They felt the public school in the area did not meet the standards they wanted. Louise Ankarcrona and Louise Westerberg were business women and decided to create a private school that would raise academic standards in Djursholm. The opened Viktor Rydberg Gymnasium, Djursholm in 1994.The school became very popular and in 1998 they opened another school located at Odenplan, in the heart of Stockhom. This school also became very popular, having a focus on the sciences. Louise and Louise were please with both school, but also wanted to focus on aesthetic arts, and so in 2003 they started a third school at Jarlaplan. Today all three schools are thriving and have become three of Stockholm's most sought after gymnasiums. Participants will ask as many of the following questions as time allows: 1. How is the ARAMIS-experiment going to be put into action? Explain how it would work. 2. Has the AMS-02 given any results about antimatter? Has the increase of sensitivity (from 10^-6 to 10^-9) given better results? 3. How could space engineering affect our planet and the environment? 4. Did you yield any significant results from the NICER project? 5. There is a lot of talk about creating a community on Mars and sending people to live there. Do you, as someone who has lived in space for a time, see this as something that is possible to achieve? 6. Based on the At Home In Space mission, how would you describe the sense of community at the ISS? 7. When you're going through the selection process, hoping to be chosen to train as an astronaut, would you admit to being afraid of anything, or would that seem not very astronaut-like? 8. How do you manage to stay in space for such long periods at a time? Is it physically and/or mentally challenging? 9. What experiments are you conducting in the Cold Atom Lab at the moment? 10. What is your goal of being an astronaut? Is it to explore new planets, contribute to science or being a part of a great adventure? 11. Which space movie made here on Earth is the most realistic? 12. Are there any space traditions? 13. What do you miss most from space when you are back on Earth? 14. What is the Earth activity that you miss the most when you're in space? 15. What made you decide being on the ISS was what you wanted to do? 16. What is your work when you're not in space? 17. What would you do if someone got severely sick? 18. How does the architecture on the ISS affect you? Why is everything white? 19. How do you navigate in the space station? 20. If you have long hair, do you have to cut it before going on the ISS? 21. How do you maintain contact with your family while on board the ISS? 22. Does the space station stay in orbit forever or does it get pulled towards earth?
