The afternoon around 2030 utc in the west coast I worked a gentleman, I thought was VE6DTX and he gave me a grid at DO81 but there is nothing on QRZ.com. My callbook with N3FJP gave me FN04. Though both are new for me, I'd like any confirmation that I worked and copied his call correctly Thank you John N7AMECN87/88 (today)

CP antenna build: unexpected discovery
by Norm n3ykf 15 Oct '18

15 Oct '18

Hi all! Built a 2x10 CP UHF antenna. Started with an Arrow 437X14. Two 7 element antennas on the same boom. Added three sets of elements. Have been using this as a linear antenna in my satellite rig. It's been performing reliably for three years, including all DX trips This is one of those projects that took a lot of learning, mostly how to use the analyzer and become good at SMA connectors. Pic of the antenna here: https://www.flickr.com/photos/n3ykf/44365875084/in/dateposted/ The next three photos are of the scans made at the end of the project, verifying CP, +/- 90 degrees. Note that the offset from the adapters has to be figured in. 18.3 degrees. Using three 9V rechargables in series to make the +V to drive the relays. RG-142b/u and SMA male connectors both from ebay. Got out to play with it a few days ago. The CP rig doesn't appear to add much to the received signal where there is no obstruction. It does make a noticeable difference toward the horizon where trees come into play. While measuring parts, I found that the little 26VDC SMA relays measured out NC and NO to 231 and 231.8 deg respectively. The actual path: 4.5cm. HUH? Managed to damage one of the relays. Bypassed the center pin crushing the female contact in the relay. So I took it apart. Nothing inside to justify an unusual measurement. Pics here: https://www.flickr.com/photos/n3ykf/44604433654/in/dateposted/ The SMA jumper that was made using 90's and adapters to connect NC->NC measured out to 281.3 degrees. Path measurement: 9.5cm. Another surprise. Doing the math, the relays appear to have a velocity factor of .1(back of the envelope math). Is this for real? A surprise considering that I've never seen anything with that low of a parameter. Catch you on the birds Norm n3ykf

W3ZM from the ARISS-USA Education Summit
by Paul Stoetzer 14 Oct '18

14 Oct '18

Good evening, I will be demonstrating satellite operation at the ARISS-USA Education Summit in College Park, MD tomorrow afternoon on the CAS-4B pass at 20:14 UTC. I will be using the AMSAT club callsign, W3ZM. If you're around and in the footprint, please give us a call! I may also pop up on a pass or two other than that, but that will be the primary demo pass for the group. 73, Paul, N8HM

The pass was literally wiped out by what I think was an "intentional" mic key which included feedback, my suspicion someone was physically holding the microphone. I did manage to pull out N6RSX & KB6LTY. A link to my recording is below. https://drive.google.com/open?id=1efUhOTs_1xq2jl9eeude6uBK0_OVAuby Endaf N6UTC / MW1BQO

South Texas grid expedition
by Glenn Miller - AA5PK 13 Oct '18

13 Oct '18

Barring unforeseen circumstances, I plan to travel to south Texas 11-15 November. I expect to activate grids EL06, 07, 08, 15, 16, 17 and 18. I'll be on both FM and linear satellites and will post which on Twitter @AA5PK. I'll also be position beaconing on APRS AA5PK-9. QSOs will be uploaded to LoTW upon my return home. Hard copy QSLs available by email request. No SASE needed. Glenn AA5PK

Upcoming ARISS contact with Valley High School, Albuquerque, NM
by n4csitwo＠bellsouth.net 13 Oct '18

13 Oct '18

An International Space Station school contact has been planned with participants at Valley High School, Albuquerque, NM on 18 Oct. The event is scheduled to begin at approximately 16:25 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and NM5HD. The contact should be audible over the state of New Mexico 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. Our upcoming ISS contact consists of several Albuquerque Public Schools, elementary, middle and high schools. Students from Chaparral ES, Mission Ave. ES, Garfield MS, and Valley High School will be asking questions of NASA Astronaut Serena M. Auñón-Chancellor. These students are part of a multi-year Federal Grant, "Engineering The Future" K-12 STEM Pathway and our high school students from Valley HS have already had experience tracking satellites and have learned about some of the essential systems to build a cubeSAT. Cadet Jared Manalo , KG5TWD, from Valley HS is in training to make the call. Questions have been submitted from all schools and students and teachers alike are getting very excited about the contact. Our contact will be streamed to all APS schools and lessons have been sent around the district in preparation. Exciting times for Albuquerque Public Schools. Looking forward to visiting with you soon. Participants will ask as many of the following questions as time allows: 1. Why did NASA originally build the Space Station, and has the mission changed over the years? 2. What is the hardest job you have done in space? 3. When you were little, did you dream of being an astronaut? 4. What kinds of hazards are astronauts exposed to on the job? 5. Do you get sick in space, and what are the procedures for an astronaut with a serious illness? 6. How well do you sleep in zero gravity, and how long do you sleep compared to your regular sleep cycle? 7. How has the ISS research prepared humans to be able to live on planets in outer space? 8. What kind of systems, testing or research is being done on the ISS to support the Deep Space Gateway project? 9. If Americans had all the materials to land on the moon in the 60's (1969) why can't we land on the moon now that we have more and better technology? 10. If a woman becomes pregnant in space, has your research shown that a fetus can develop normally? 11. What kind of physical and mental testing do you get to be ready to go into space? 12. What kind of medical testing does an astronaut have to go through to be ready for duty? 13. When in space can you see the earth spinning or rotating? 14. How many years of hard work is required to become an astronaut, and what is the best degree to get as an astronaut? 15. What is the ISS crews response if the Space Station is hit with space debris or a meteorite? 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), 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.
