Small update to KLA Track
by Chris Thompson 09 Oct '19

09 Oct '19

If you use the G0KLA Sat Tracker then I have made a minor update to the display to improve the rendering. There are no other changes so this is very optional. You can download it here: https://www.g0kla.com/klatrack/index.php If you want to know what I fixed that is discussed here: https://www.g0kla.com/workbench/2019-10-08.php -- Chris E.

ARISS Contact Applications (United States) Message to US Educators Amateur Radio on the International Space Station Contact Opportunity Call for Proposals New Proposal Window is October 1, 2019 to November 30, 2019 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between July 1, 2020 and December 31, 2020. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is November 30, 2019. Proposal information and documents can be found at http://www.ariss.org . The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations' volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

Re: [amsat-bb] Counterbalance weight on antenna rotator?
by MICHAEL WILLIAMS 09 Oct '19

09 Oct '19

My thinking has been to put it out of balance, especially with the light weight satellite antennas we use. In a perfectly balanced system, the wind will work the gearing back and forth. In an unbalanced system, the gears will stay meshed in one direction not working the internal parts when the antennas are moving or are at rest. It's difficult to balance a system when coax and preamps added to the rear. It's also good to have the least wind resistance when SatPC32 returns antennas to the rest position The Yaesu elevation rotors are pretty tough. I used an Alliance U-110 for years with no problems. Talk about out of balance, check my qrz page. Good luck with this. It has been an interesting subject. 73, Mike (K9QHO)

Re: Counterbalance weight on antenna rotator? (Bob Hammond) My antennas are mostly "center" mounted because of their length and are pretty well balanced as a result. For antennas rear mounted to the cross boom, a length of tubing extending in the opposite direction from the antennas could be used with an adjustable weight that can be positioned to achieve the correct balance. The idea of a counter balance weight is interesting, but the antennas present a variable load depending upon the elevation. The weight on the cable presents a constant load independent of the elevation. Worse yet, I use a flip mode tracking that resolves the issue of having the satellite path cross the stops of the azimuth rotor and having to rotate the antennas 360 degrees to continue tracking the satellite. But this requires 180 degree movement of the elevation rotor. The weight on a cable would then add to the weight of the antennas which would make the problem worse and make the elevation rotor work twice as hard. See a picture of my home satellite installation on qrz.com by looking up N7JK. Using an opposing counterbalance weight mounted opposite the antennas can essentially change the function of the elevation rotor to being simply a positioning device if the array is properly balanced.
