Mike, That's good news as +16 dBm is 40mw and not 200mw as I previously wrote. So one could use a standard transverter with the amp for terrestrial 5-GHz. The satellite ground station will have integrated SDR transceiver for digital modes, being discussed by planning groups. That will also be good news for the average satellite operator since it will eliminate having to scrounge up surplus mw gear and "roll your own". 1m ku-band offset feed dishes are the "norm" for home satellite here in AK so the antenna should not be hard to get. Az-el may require some ingenuity; I'm thinking reuse of small telescope tracking drives which will have necessary finest of pointing. 73, Ed - KL7UW Date: Mon, 11 Apr 2016 06:00:05 -0400 From: Mike Seguin <n1jez(a)burlingtontelecom.net> To: amsat-bb(a)amsat.org Subject: Re: [amsat-bb] Link budgets for upcoming HEO/GEO sats Message-ID: <570B75A5.2090405(a)burlingtontelecom.net> Content-Type: text/plain; charset=windows-1252; format=flowed Everyone, This has been tested already. A fellow ham has done it and shared findings with me. The 600 mW drive is with a pad still inline on the input. If you bypass it, drive drops to 10-12 dBm range. The devices used are from Skyworks. SE5004L. There are two in push/pull. We have been discussing this amp on the phase4ground list for use as a test bed. Ed, this would make a very nice amp for portable 5760 use.

Dragon first stage recovery?

Is there any information on how they are going to secure the first stage for return? Doing so on land is, as such things go, trivial, but on an autonomous ship in rough waters adds many complications. 73s, Alan WA4SCA

Upcoming ARISS contact with National Soaring Museum, Elmira, New York
by n4csitwo＠bellsouth.net 11 Apr '16

11 Apr '16

An International Space Station school contact has been planned with participants at National Soaring Museum, Elmira, New York on 01 Apr. The event is scheduled to begin at approximately 18:34 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 OR4ISS and IK1SLD The contact should be audible over Italy 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 National Soaring Museum sits atop Harris Hill, overlooking Elmira, New York, the "Soaring Capital of America". The National Soaring Museum was established in 1969, and underwent expansions in 1979 and 1989. The Soaring Museum is home to the Soaring Hall of Fame, and the Soaring Society of America's Archives. By collection, the NSM is the largest museum in the world dedicated to motorless flight. In 1972, the New York State Department of Education chartered the Museum as a non-profit educational institution. Its role as an educational institution provides youth with unique experiences to learn about the science and history of aviation. The Museum offers overnight soaring encampments for youth groups, and two summer camps: the Summer Soaring Academy, and Eileen Collins Aerospace Camp (ECAC). The Summer Soaring Academy is in its fourth year, and offers local students a hands-on look at aviation and engineering, capping off the week with a glider ride for all students. The Eileen Collins Aerospace Camp - named for the Elmira native who would become the first woman to command a space shuttle mission - is a weeklong adventure in aviation and space exploration. The week is filled with hands-on activities, trips, and rides in a sailplane and power plane. ECAC is one of the few in the United States that gives students an opportunity to fly in airplanes. This Harris Hill remains an active gliderport, with a strong Junior and Senior program. Several youth who attended this camp have joined the Harris Hill Juniors to become glider and power pilots themselves. Participants will ask as many of the following questions as time allows: 1. What made you want to become an astronaut? 2. Have there been any injuries on board? 3. What's a day in space like? 4. How do you stay stationary on space walks if the ISS is moving? 5. How far can you be from Earth and still talk to Mission Control? 6. Have you ever been on a mission that's gone badly? 7. How does microgravity feel? 8. How fast does the ISS go, and can you feel it moving? 9. Has there been any "unearthly" sightings? 10. What are you studying? 11. Were you scared when you went into space? 12. How do you talk to your family? 13. What courses in school do you have to take to be an astronaut? 14. What does it feel like to enter and exit the atmosphere? 15. Are space walks difficult? 16. Is microgravity difficult to deal with? 17. Do you bring something with you to remind you of home? 18. How long does it take to become an astronaut? 19. How do you control the rocket that takes you to the Space Station? 20. What's the most rewarding thing about being an astronaut? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook. We can be found at Amateur Radio on the International Space Station (ARISS). 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), 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.

John, etal: Hope someone tests this and gives a report. Cost is quite reasonable for this kind of power at 5-GHz. Note that the DEMI 5670-144 transverter output is +16 dBm (200mw) so one could obtain 2w with drive from one. ERA-5 was common mmic used for this level. Getting 600mw is a bit harder. Most of these run class-A so do dissipate a lot of heat; most of the power becomes heat and not RF. 10-dB RF gain is respectable at microwave. Comment on az-el suitable for 1m dishes at 5 and 10-GHz. The Yaesu satellite rotators do not resolve pointing angle less than 7-1/2 degree so probably not adequate. There are some inexpensive telescope drives that might work at reasonable prices. 73, Ed - KL7UW Date: Sun, 10 Apr 2016 13:24:40 -0500 From: John Toscano <tosca005(a)umn.edu> To: n1jez(a)burlingtontelecom.net Cc: AMSAT BB <amsat-bb(a)amsat.org> Subject: Re: [amsat-bb] Link budgets for upcoming HEO/GEO sats Looking forward to testing mine too.

I have the Doppler.sqf file set correctly for the 145.825 Packet Robot, and I can see the SatPC32 display show me both the uplink and downlink frequency with logical doppler corrections. However, If the radio is in Satellite mode, it insists on transmitting on 70cm, or if I take it out of satellite mode, only the downlink frequency is actually corrected (it will transmit on the downlink frequency as well). Does anyone have any experience using SatPC32 with a Icom radio on the ISS Packet Robot? 73, Bob, WB4SON ------------------------------ Message: 2 Date: Sun, 10 Apr 2016 17:21:14 -0400 From: Dave Webb KB1PVH <kb1pvh(a)gmail.com> To: Bob <WB4SON(a)gmail.com> Cc: AMSAT-BB <AMSAT-BB(a)amsat.org> Subject: Re: [amsat-bb] SatPC32 Setup for ISS Packet Message-ID: <CAEMY9FcFBc2Fkn+Rp90DSENHnU0+JqJhKDn8DCJyv5x52f7nkQ(a)mail.gmail.com> Content-Type: text/plain; charset=UTF-8 Bob, Use SatPCISS because it puts the radio in same band split mode.

Sadly it is not possible at the moment to directly answer your question about possible transponder operations on FUNcube-2 but we hope that it will be possible in the fairly near future. In the meantime, the FC2 transmitter is currently continuously downlinking valid real time telemetry. This provides a good overview of the on board systems and thanks, to the many stations regularly listening (using the normal Dashboard), this data is available on the FUNcube Data Warehouse. Of course we can be looking forward to the launch of the 1U CubeSat - Nayif-1 around the middle of the year. This will also carry a FUNcube transponder and is presently being prepared for insertion into its QuadPack deployer. This operation will take place within the next few days and is in preparation for launch in mid summer on the same launcher as Fox1-C and Fox1-D. 73 Graham G3VZV -----Original Message----- From: J.

The event is scheduled to begin at approximately 13:48 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and YO9INI. The contact should be audible over Romania 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 University Valahia of Targoviste (UVT) and its partners are organizing the first Romanian ARISS contact in this historic capital of Wallachia, where ruled Vlad the Impaler, also known as Vlad Dracula. The Faculty of Electrical Engineering, Electronics and Information Technology started its activity in 1995 and it is known for electronics, telecommunications, automation, computer science, electrical engineering and power energy, providing eleven bachelor's, master's and doctoral programs for over 780 students. It has a chapter for IEEE Broadcast Technology Society (Romanian section). We are proud of our students' involvement in several international challenges, conferences and various research events. For the ARISS contact UVT trained 20 pupils aged 12 to 18 who were recruited from different high schools in the county. Their training was offered through the European Space Education and Resource Office ESERO-Romania, which is a collaboration between ESA and national partner s (ROSA). The ARISS event was also supported by several companies and associations, namely Vodafone Romania and Start-Tech Association. Participants will ask as many of the following questions as time allows: 1. What are the qualities that define an astronaut? 2. What is the worst and the best part of your job? 3. Have you ever felt the impact of space debris hitting the ISS? 4. What was the most difficult test that you took during your astronaut training? 5. What is an everyday thing which is extremely difficult on ISS? 6. What is the most beautiful thing that you can see from space? 7. Have you ever observed solar radiation affecting ISS radio comm? 8. Is radio comm a passion or a job obligation? 9. What is the most interesting discovery made on ISS using plasma? 10. What's the biggest difference between expectation and reality when living in space? 11. Has food the same taste in space? 12. What is the first thing you will be doing when you come back to Earth? 13. What is your most challenging task on the ISS? 14. How did your know you had a passion for exploration? 15. Do you think spaceflight will be accessible for the masses in the future? 16. Given the chance, would you live exclusively on Earth, or on the ISS? 17. Has space travel changed your life? 18. Is it true that after coming back you shouldn't expose yourself to sunlight? 19. What do you do in your free time? 20. What is the coolest thing that you've done in microgravity?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), 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.
