by Bennett Norell 23 Mar '18

23 Mar '18

For Sale - Kenwood TS-711A 2m and TS-811A 70cm all mode radios. From an estate, simple testing shows works as they should. TS-711A has voice option, both have the tone board TSU-5 option installed and both have built-in AC power supply. The 711A is in very good condition (face perfect), with a small chip/crack in top right back surface of the bezel, other wise very good condition. The 811A is also in very good condition, with wear marks on the left and right sides of bezel (don't see head-on). The 811A backlight for the meter is a little flaky, but tap the case and it comes back on. Both come with Kenwood hand mic, AC power cord, original manual. $300 plus shipping for the 711A, $350 for the 811A, plus shipping, unless picked up NNJ. Sold as-is due to parts swappers, but can demo if picked up.

Yaesu rotator connections
by Rolf Krogstad 23 Mar '18

23 Mar '18

I have a Yaesu G-1000-DXA rotator and controller for azimuth. After I got into working satellites I purchased a used Yaesu G-5500 elevation rotator and the dual Az/El controller. (Thanks AA5PK it has been working great!) I would like to hook the G-1000-DXA cable to the G-5500 controller but can't figure out how the pins correspond. Both are 6 wire cables. I found a better schematic for the G-5500 on the Yaesu site than was in my manual - it appears pins 4-5-6 have to do with power for the G-5500. On the G-1000-DXA pins 4-5 are power, so in a wild guess I tried hooking 1-1, 2-2, 3-3, 4-4, 5-5, 6-6, but nothing happens. Does anyone know how I need to hook this up? Thanks Rolf NR0T in EN34

Upcoming ARISS contact with Freeport Public Schools, Freeport, NY
by n4csitwo＠bellsouth.net 22 Mar '18

22 Mar '18

An International Space Station school contact has been planned with participants at Freeport Public Schools, Freeport, NY on 27 Mar. The event is scheduled to begin at approximately 17:41 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. Freeport Public Schools is located in the city of Freeport, about 25 miles east of New York City. The district is composed of 8 schools---one pre-K school, four elementary schools, one intermediate middle school, one middle school, and one high school. The total student enrollment is 7,400 and 90% of the students are Hispanic or African-American. Science is taught in all grades, and at the high school students enroll in Advanced Placement classes in physics (calculus and non-calculus based), chemistry, biology, and environmental science. We also have a research class in each of the grades 7-12 that is open to all students. Our students have participated in the International Astronomical Search Campaign to confirm or discover asteroids that exist in the asteroid belt. We confirmed the discovery of two asteroids, received two plaques from NASA and then published a paper on our work in a leading physics educational journal. One of our teachers and his students travelled to California Institute of Technology to take part in NASA/IPAC Teacher Archive Research Program. One of the students who participated in this research program is now majoring in astrophysics. Our students have been preparing for our conversation with Scott Tingle from early last summer. This unique opportunity to speak and observe Scott in the International Space Station has generated tremendous enthusiasm for science among our students. Going forward, we plan to design an experiment that can be conducted in the Space Station. At some point in the future we would also like to invite Mr. Tingle to come to our school and give a science seminar. Participants will ask as many of the following questions as time allows: 1. If an astronaut gets a bacterial infection, do antibiotics work in space as they do on Earth? 2. Could you describe the ?SUPVIS Justin? experiment you conducted on March 2 and the next steps in this work 3. How has your perspective about the Earth changed as a result of your trip to the Space Station? 4. What are the duties of a typical astronaut on his/her first day in space? 5. Does the immune system become impaired after a prolonged stay in space? 6. What does it look like from space when seasons are changing? 7. How does age effect how the body reacts in space? 8. What are the uses of the robotic arm? 9. You plan to do one or more spacewalks in your trip aboard the ISS. Could you describe the biggest challenge you face in such missions? 10. How often and how does ISS adjust its trajectory to maintain a constant orbit? 11. If astronauts leave the Earth at around 17,000 mph why does it take so long to reach the ISS located approximately 250 miles above the Earth? 12. I know you like fluid mechanics. Could you describe the fluid mechanics experiments you are involved in? 13. Has the ISS National Laboratory found any possible organisms that can survive the harsh conditions of space for a prolonged period of time? 14. What would happen if you got sick in space? 15. You will be doing a number of experiments aboard the ISS. Could you describe one that interests you the most? 16. How can we help pets to survive in outer space for longer periods of time? 17. What are the effects of blood rushing to astronauts? heads in a microgravity environment? 18. You were one of the first responders in the September 2001 terrorist attacks. Could you describe your role? 19. Knowing there is debris in space can you describe briefly how ISS detects objects moving toward the station? 20. Due to varying laws governing research in various countries, does each country work solely on their own project or are projects codependent? 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): TDB 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. For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

Re: [amsat-bb] Nova for windows and Picsat
by IW1DTU Fer 21 Mar '18

21 Mar '18

Hi Jerry nova for windows is excellent and I use it everyday . Consider satpc32 too, very useful if you operate transponders. I have my old TS-790 CAT connected to satpc32 and doppler correction is automatic in both downlink and uplink. Easy to connect to SDR# too if you just want to receive telemetry with doppler connection. 73 Fer IW1DTU On Wednesday, March 21, 2018, 1:59:33 PM GMT, Gerald Witalec <jplanner(a)sbcglobal.net> wrote: Thanks Fer.
