How many things can go wrong at once?
by Burns Fisher 20 Oct '18

20 Oct '18

A couple days ago work G0ABI via AO-91 based on a sched we had made. Suddenly the elevation in my rotor did not work! So I moved it by hand, called and called...I did not hear myself. Later Peter sent me a recording--he had heard me just fine so my Rx was screwed up Today, I found the rotor problem (a cable). I had hoped it would be the same problem with the Rx (like a hungry mouse) but no, apparently not. So I tried 91 again today. Wait, why is the downlink band so quiet? First, something had happened to my database in MacDoppler and it was all hosed. It had the AO-91 as a V/u satellite and the wrong freq anyway. Fixed that in time. Still very quiet on the band. Took my HT to probe around a bit. Some strong carrier on 145.965. I went outside and suddenly heard a voice. Aha! Someone using the satellite band! Oh, wait, that is AO-91 booming in on my HT with rubber ducky at about 5 degrees above the horizon! That was actually pretty cool! (I was probably hearing contacts with SparkFest!) Still trying to find the source of the 145.965 (besides AO-91 of course). It is clearly inside my house--I even know which breaker. But so far not the obvious things (power supply, network switch, computer, UPS, etc). I'll keep looking. But it just goes to show that when a bunch of things happen at once, it is not ALWAYS due to the same root cause. 73, Burns WB1FJ

AO-91 demo today 1714 UTC - 2018-10-20 from SparkCON
by John Brier 20 Oct '18

20 Oct '18

Hi all, I will be doing a demo from downtown Raleigh, NC (FM05) today for SparkCON, an annual "creativity festival." SparkCON has lots of sub groups for various creativity pursuits like poetrySPARK and fashionSPARK. I will be doing the demo for geekSPARK. https://sparkcon.com https://sparkcon.com/geekspark/ I decided to do this demo last minute so it is not on the schedule. This AO-91 pass is a good pass because it goes N-S and is high elevation (68 degrees) and I will be on Fayettville street which is also N-S and is the main downtown road which is surrounded by tall buildings. I have not tested the area for QRM though, so that may be an issue. Anyway, if you hear me, give me a call! 73, John Brier KG4AKV P.S. Serena Aunon-Chancellor is on the mic from NA1SS today and making random contacts according to reports on Twitter from Patrick WD9EWK and others. Good luck to all who call her!

Dear A.Tahir: Through a telephone call, I also learned this: The USA Yaesu office has changed the old P/N 8000379 to new P/N S800947 (same part, new number) and The USA Yaesu office has this part in stock (cost several US Dollars plus shipping). Perhaps the U.K. Office may also (have the part in stock)? I hope this helps!

Each year, ARISS provides tens of thousands of students with learning opportunities about space technologies, communications, and much more through the exploration of Amateur Radio and space. ARISS has been pleased of late, to be one of many possibilities of interest to educators during NASA’s A Year of Education on Station, which celebrates an almost 12-month presence of a teacher aboard the ISS. The ARISS program connects students to astronauts on the ISS through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, other Amateur Radio global organizations and the worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering, and mathematics (STEM) and in Amateur Radio. Educators report regularly that student participation in the ARISS program stimulates interest in STEM subjects and STEM careers. One educator wrote, “Many of the middle school students who took part in and attended the ARISS contact have selected science courses in high school as a result of that contact.” Educators are setting up ham radio clubs in schools and learning centers because of students’ interest. ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and other STEM subjects. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for a once-in-a-lifetime opportunity for students. The proposal window opens October 1, 2018 and the proposal deadline is November 30, 2018. For proposal guidelines and forms and more details, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html Proposal webinars for guidance and getting questions answered will be offered October 11 and October 23, 2018, both at 8 pm Eastern Time. Advance registration is necessary. To sign up, go to: ariss-proposal-webinar-fall-2018.eventbrite.com/ ARISS Contact Applications (Europe, Africa and the Middle East) Schools and Youth organizations in Europe, Africa and the Middle East interested in setting up an ARISS radio contact with an astronaut on board the International Space Station are invited to submit an application from September to October and from February to April.

Re: [amsat-bb] Antenna for 1200MHZ for satellites and EME Activity?
by Ronald G. Parsons 18 Oct '18

18 Oct '18

I just put together an M2 23cm antenna 23CM22EZA, 1250-1300 MHZ, 18 dBi gain. It is a new design with the elements in two metal stampings, eliminating all those locking washers on each element. It is rear mountable, either H or V polarization. Very simple to assemble. Ron W5RKN
