Re: [amsat-bb] Karl Janskey call sign
by Kevin M 02 May '19

Hi Jim, If you will forgive the correction, Reber's callsign was W9GFZ. And while it may be the same club in both places, the call is assigned to the club's address at the observatory in Socorro NM, not WV. (And that's PO Box 'O'... not PO Box 'zero' for anyone wondering like I did.) I screwed up the link in my previous message, but here it is again, hopefully it will work correctly this time: https://www.nrao.edu/whatisra/hist_ham.shtml -------------------------------------------------- Both Janski's and Reber's radio telescopes are on display at the National Radio Astronomy Observatory at Green Bank, WV, the home of the world's largest steerable radio telescope. If you ever get near the area, a stop at the facility with its many telescopes and excellent visitor's center is a MUST.The observatory's radio club has been granted Reber's call, W9GVZ, They use it to commemorate radio astronomy in special events. I spent several summers as a physics teacher studying radio astronomy at Green Bank and was able to help operate W9GVZ during a special event at the dedication of the Robert Byrd Telescope in August, 2000. I have to tell you that Green Bank is quite a place. I get back there as often as I can!

Upcoming ARISS contact with Mildred Hall School, Yellowknife, NT, Canada
by n4csitwo＠bellsouth.net 02 May '19

02 May '19

An International Space Station school contact has been planned with participants at Mildred Hall School, Yellowknife, NT, Canada on 03 May. The event is scheduled to begin at approximately 18:32 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 NA1SS and LU8YY. The contact should be audible over Argentina 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. Mildred Hall, a Junior Kindergarten to Grade 8 School, is located in the heart of downtown Yellowknife with Frame Lake and its beautiful trail almost sitting in its backyard. It houses 271 students from the ages of 4 to 14 with very diverse backgrounds and cultures. Almost 80% of the students are Indigenous, so it boasts programming that is relevant to hands-on learning, science inquiry, outdoor experiential opportunities and the instruction of English, French and Dogrib. Our basic beliefs revolve around the acronym SOAR- Share what you have (S), Ownership (O), Achieve your very best (A) and Respect everyone and everything around you. (R). Participants will ask as many of the following questions as time allows: 1. Why is space travel so important to astronauts and other humans? 2. I saw a picture you took of the northern lights and we have a lot of them over here in Yellowknife. Are you able to fly through the northern lights? 3. How do you see the sun from where you are? Is there a sunrise or sunset? Is it different to how we see it on earth? 4. How long are you there and how long can a person stay in space? Does it affect your body in anyway, causing irreversible consequences? 5. Do you constantly work up there? Do you do anything for fun? If so,what? 6. What is your favorite thing about being in space? 7. What is the most challenging thing about being in space? 8. Does your hair and nails grow at the same rate in space? Is there anything different about the way they grow? 9. If there is an emergency on the space station and you have to escape, is there an emergency pod? If not what happens? 10. What is gravitational time dilation? 11. How do you keep time in space? Are you in a time zone? 12. Do you think humans will ever live on another planet? 13. What were you thinking when you blasted off? 14. What is the strangest thing you have ever seen or experienced in space? 15. Is it as silent as movies show? Why? 16. What do you miss the most while you are there? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook.

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.

Diwata-2, PO-101 times clarification.
by Nicholas Mahr KE8AKW 02 May '19

02 May '19

Hi Tom, They are in UTC+8. However next week when they release the new schedule it should just be in plain regular UTC time to make it less confusing. In the mean time use this calculator to convert it https://www.timeanddate.com/worldclock/converter.html?iso=20190423T040000&p… . As of right now its only on late at night here in NA during east coast passes roughly past 1:00 AM in the morning. - Nick KE8AKW

Diwata-2, PO-101 times clarification.
by tjschuessler＠verizon.net 02 May '19

02 May '19

Looking at the schedule for FM repeater use on Diwata-2 available at https://twitter.com/Diwata2PH, I assume the times listed there are local but denoting they are UTC+8. Looking at Diwata-2 passes over the US, I think this means that these times are mot in sync with North America availability? I may well be miscalculating though so please correct if wrong.

Formatting HRD Passes File
by k6vug＠sbcglobal.net 02 May '19

02 May '19

I have been using HRD for a long time, it produces a very useful text file, called "passes.txt", listing the pass predictions for your grid square. If you use HRD Satellite and know how to create the passes text file, you'll know what I'm referring to. I have created a simple utility that formats the text file for better readability. The utility can be downloaded at the link below. I use it all the time and am passing it along if anyone may find it useful. https://drive.google.com/open?id=1YPzTaLsp7deFUd8CyoHADbyH9G5vR-z0 In this public folder look for the file called "HRDPassesFormatter.exe". There nothing to install just download it to a convenient folder and double-click to run it. All you have to do is to select the HRD passes file. 73! Umesh k6vug

Satellite/AMSAT presentation & demo in Mesa AZ on 21 May 2019
by Patrick STODDARD (WD9EWK/VA7EWK) 02 May '19

02 May '19

Hi! I will give a presentation on how to work amateur satellites and AMSAT, along with a demonstration of satellite operating, during the Superstition Amateur Radio Club's monthly meeting on Tuesday, 21 May 2019. The meeting will be at the City of Mesa's Charles K. Luster Building, located at 640 N. Mesa Drive. in Mesa, Arizona. This is on the west side of Mesa Drive, and north of University Drive. The meeting starts at 7pm (0200 UTC on 22 May). More information about the club is available at: http://superstitionarc.org There appears to be an AO-92 pass coming by after the meeting wraps up, around 9.15pm (0415 UTC on 22 May). This pass should cover much of the continental USA. I plan on using this AO-92 pass for a demonstration of satellite operating. If you hear WD9EWK on that pass, please call and be a part of the demonstration. The meeting site is in Arizona's Maricopa County, grid DM43. QSOs made during the demonstration will be uploaded to Logbook of the World. QSL cards are available on request (please e-mail me with QSO details). Thanks, and 73!

Re: [amsat-bb] Fox -1B / AO-91 in trouble?
by Alan 02 May '19

Hans, Looks like if it IDs, the signal is normal and you get the usual 2 telemetry frames. If the transponder has been brought up, you get the odd signal, with a brief switch to DUV at the end, but no telemetry.
