[amsat-bb] AMSAT at Orlando
Hi All I attended the AMSAT conference in Orlando and it was fantastic. The presentation were excellent and the high school students were inspiring. So a big thanks to Lou and his crew and the AMSAT leadership for a great conference. Thanks nick ars k5qxj EM30xa 30.1 n 90.1 w cell 337 2582527 office 337 593 8700 ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: AMSAT at Orlando
I'll second that, Nick. Indeed, hearing about a high school group that is building a CubeSat as an after hours school project is amazing. More impressive is how articulate and composed the two presenting students are! The whole way home I was thinking about what a great group of people AMSAT is. If you've never been to an annual Symposium, you really should give it a shot. Haven't heard where it might be next year, but when it's announced, get it on your calendar! Dayton 2013 presents a great opportunity to engage as well. It's priceless to sit and chat face to face with folks you've talked to on a bird-one time, or dozens of times. Further, hearing AMSAT stories both old and new is one of my favorite parts of getting together. Hearing Hector CO6CBF speak was one of the most inspiring presentations I've heard, ever.

[amsat-bb] orbitron question thanks
Thanks to everyone who replied. There were two solutions, Pre filter the download from Celestrak so that only the wanted sats go into the TLE file. Edit the TLE file in Orbitron to remove the unwanted sats. Both good solutions. 73 John G7HIA ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] ARISS Project Wins Public Relations Award
Special event with astronaut wins public relations award - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - As Clint Bradford of Jurupa Valley said, “It was 13 months of planning for 10 minutes of conversation, but, oh!, what a conversation!” “‘LIVE! … from outer space!’ Students speak to an astronaut in the orbiting International Space Station” was the special event on April 19, 2012 that earned an award for Karen and Clint Bradford in annual competition by the Public Relations Society of America. The event was planned for the 120 students of Flabob Airport Preparatory Academy and more than 80 parents, community leaders, media representatives and interested persons. Clint initiated the event because of his hobby in ham radio and volunteer position with NASA through Amateur Radio on the International Space Station (ARISS): He provides school technical support for students in North America to talk to astronauts aboard the orbiting space station. NASA’s “Teaching from Space” program is available to any school that applies, but the typical wait-time from application to event is three years. He approached Kathy Rohm, vice president and director of community relations at Flabob Airport Preparatory Academy, which is supported by the Tom Wathen Center. She was enthusiastic to sponsor the literally out-of-this-world, once-in-a-lifetime special event to inspire students. More than 2,900 emails flew between Clint, Kathy, NASA, Flabob staffer Nina Bentham and ARISS volunteers to produce the event. NASA-Houston flight director Phil Engelauf, who grew up in Rubidoux and whose mother, Beverly, still lives here, was invited to the event. His duties prevented him from attending, but he sent warm regards to the students in a special message that is posted at the event's Web site - http://iss-flabob.com (on the blog). The event went according to plan, except for a momentary glitch with audio quality, despite having tested the system for three days preceding the event. Clint quickly figured out a solution, although he later said that he was only 90 seconds from NASA terminating the call if he had not succeeded. “When we looked around the hangar at the conclusion of the contact, hearing the students’ whoops of happiness, we saw more than a few adults wiping at their eyes … us included,” Karen said. “We felt intensely rewarded to think how our students may feel throughout their lives when they look up in the sky and remember the thrilling day when Flight Engineer Don Pettit answered their questions.” Student Brittany Cain had asked, “Besides missing your family and friends, what is the biggest adjustment you have made for this mission?” The assembled group laughed when Pettit replied he missed not being able to take a bath for six months! The mission of Flabob Airport Preparatory Academy is to use aviation as a tool to motivate students to achieve their personal, academic, and career goals. Current statistics reveal that American students severely lag behind their foreign peers: In a study of 31 countries, the Organization for Economic Cooperation and Development ranked Americans 21st in science and 25th in math. Consequently, President Obama launched the Educate to Innovate Campaign in 2009 to unite teachers, parents, businesses and students toward excellence in STEM (science, technology, engineering and math) studies. Karen is a current member and past president of PRSA’s California Inland Empire Chapter. There are more than 80 local members. ### ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Polarization for ISS and Weather Satellites
The polar orbiting NOAA weather satellites have right hand circular helical antennas for the VHF APT service. Right hand circular polarization is recommended for NOAA APT receiving antennas. http://www.noaasis.noaa.gov/NOAASIS/pubs/Users_Guide-Building_Receive_Statio ns_March_2009.pdf See the section on ground station antennas, p. 45 Grant Zehr AA9LC -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Graham Dillabough Sent: Saturday, October 27, 2012 3:58 PM To: amsat-bb@amsat.org Subject: [amsat-bb] Polarization for ISS and Weather Satellites I haven't posted here in a very long time. I hope this works. I am building two Quadrifilar Helix antennas (from QST, August 1996); one for weather satellite experimentation, and one as a backup antenna for an upcoming ARISS contact. I haven't found anything in the ARRL antenna book, or on the web, that specifically says that one mode (RHCP or LHCP) of circular polarization is better than the other for either of the two applications noted above. Any insight or experience with polarization issues with the ISS and weather satellites are appreciated. The last time I did an ARISS contact, I was plagued with very deep fades, and want to do better this time. Thanks, Graham Graham Dillabough, VE6KJ, VO1DZA Albert Einstein, when asked to describe radio, replied: You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat. Albert Einstein (1879-1955) ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] WSJT - A Bit Off Topic
I'd be interested in hearing from anyone who is using WSJT with an FT-847 and Signalink USB interface. I'm having no luck getting PTT to work. Rick W2JAZ ___ Sent via AMSAT-BB@amsat.org.
