Get SatPC32 back to center
by Tom Schaefer 10 Mar '20

10 Mar '20

If I turn the VFO manually (via VFO knob), is there an easy way to get SatPC32 back to the center of the passband? Is there a button that cancels the effects of the manual tuning? This would be for full Doppler tuning. Thanks Tom NY4I Principal Solutions Architect Better Software Solutions, Inc. 727-437-2771

FOX LEADERBOARD
by James Jipping 10 Mar '20

10 Mar '20

Good Morning! What do the headings "TOTAL" and "LAST 7 DAYS" mean on the FOX TELEM LEADERBOARD. "LAST 7 DAYS" is obvious. My numbers keep bouncing around, that's expected. But, NOW, my "TOTAL" number bounces around too. Shouldn't they be constantly increasing. Also at the end of February I had number about 12500 after several months of ever increasing numbers. But on March 3, I had only 8600 and they have been bouncing ever since. On March 10 I have 8533 after 1845 frames/payloads. In March, thanks to the kind and expert help of Burns Fisher, WB1FJ, I started using a FIAB setup. Does that have anything to do the drop and bounce ?? Thanks, I'm going back to bed.

AO-92 L band on the weekends
by Jeff Johns 10 Mar '20

10 Mar '20

When can we expect to see AO-92 L band activations on the weekend again? When it was moved to Wednesdays, it was touted as temporary. How long is temporary? Usage of L band on Wednesdays is minimal at best. AO-92 (to the best of my knowledge) is the only amateur satellite with an L band uplink. I would think as more amateurs get Icom 9700s that they might like to give it a try. I understand not everyone can be pleased but a majority of people work during the week or have other family duties, such as childrens’ school nights that might limit their access to the satellite during the week. Can we expect the “temporary” Wednesday activations to return to the weekends any time soon? After all, all AMSAT members should have a fair chance at using the L band uplink to test/use their equipment. It can always go back to Wednesdays after a while. Jeff WE4B

Message to US Educators Amateur Radio on the International Space Station Contact Opportunity Call for Proposals Upcoming Proposal Window is February 1, 2020 to March 31, 2020 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 is happy to announce a proposal window will open February 1, 2020 for contacts that would be held between January 1, 2021 and June 30, 2021. 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 proposal window for contacts between January 1, 2021 and June 30, 2021 will open on February 1, 2020 and close on March 31, 2020. Proposal information and documents can be found at www.ariss.org. Two ARISS Introductory Webinar sessions will be held on November 7, 2019. The first is at 6:00 PM ET and the second is at 9:00 PM ET. The same material will be covered during both sessions, so choose the session that best fits your schedule. The Eventbrite link to sign up is https://ariss-introductory-webinar-fall-2019.eventbrite.com . 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. More Information For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org. Please direct any questions to ariss.us.education(a)gmail.com.

ARISS contact mentioned in article about W. VA radio quiet zone
by John Brier 09 Mar '20

09 Mar '20

https://www.nytimes.com/2020/03/06/us/green-bank-west-virginia-quiet-zone.h… I love it when I'm reading a random article and ARISS is mentioned. "The observatory has long worked to share its scientific and engineering expertise with local schools, a partnership that has paid off most recently with the announcement that the Green Bank Elementary-Middle School was one of 10 schools nationwide selected to host HAM radio contacts with International Space Station crew members later this year." The text in the article also links to an ARRL page about the selected schools: http://www.arrl.org/news/view/ariss-announces-hosts-for-space-station-ham-r… 73, John Brier KG4AKV

CP antenna feed
by Tim N8DEU 09 Mar '20

09 Mar '20

There was an article written several years about feeding the cable off the end of a CP antenna versus running the cable up the boom the center with the results. Does anybody recall what edition of the Amsat Journal this was published? I am looking to forward this is to new satellite operator to help with his decision. I spent 4 hours looking for that article and came up empty. Thanks in advance, Tim - N8DEU

HuskySat telemetry
by Jeff 09 Mar '20

09 Mar '20

I've been collecting HuskySat-1 telemetry for a while and recently my collected data isn't being accepted by the Fox Telemetry site. I see this 'Only real time data being processed' message the the Fox Telemetry site, but see 4 or 5 other stations getting their data uploaded. Does anyone know what's going on here? As my, others data isn't being accepted I see no reason to collect any more data. 73 Jeff kb2m

Minor bug fixes for FoxTelem
by Chris Thompson 09 Mar '20

09 Mar '20

I have updated FoxTelem and the latest version is here: http://amsat.us/FoxTelem/windows/ http://amsat.us/FoxTelem/linux/ http://amsat.us/FoxTelem/mac/ This is not a mandatory upgrade. It fixes some minor bugs that caused crashes and corrects the calculation of the bit SNR for the Dot Product BPSK detector. If you use the Dot Product detector and you care about the measured bit signal to noise ratio, then you want to upgrade. Note that if you use Find Signal in IQ mode then the bit SNR level is used to determine if the signal is found. Because the level has changed you will need to adjust the threshold value. Email me if you need more information. Please let me know if you see any issues, or log them on github here: https://github.com/ac2cz/FoxTelem/issues 73 Chris -- Chris E.
