Re: [amsat-bb] ISS FM Repeater

The radio should be in packet mode. I am going to try and indicate what mode the radio is being set back to after an ARISS contact when I post the ARISS announcements to the AMSAT-BB. I will also try to let everyone know what mode is being used if the mode changes again between ARISS school contacts. 73,Charlie Sufana AJ9NOne of the ARISS Mentors In a message dated 2020-10-15 09:28:14 Eastern Standard Time, amsat-bb(a)amsat.org writes: Hi Jose.

Free: 1, 000 ft ultra low loss air core coax in Austin Texas
by John Brier 14 Oct '20

14 Oct '20

Would be cool for a sat op to get this. 73, John Brier KG4AKV From: n3bb <N3BB(a)mindspring.com> Date: Wednesday, October 14, 2020 Subject: [CTDXCC] Free Coaxial Cable To: CTDXCC <ctdxcc(a)lists.kkn.net> Ten years or so ago, I purchased 1,000 feet of "ultra low loss" coaxial cable. It turned out that I could not use it because it has an air core and special end connectors. It is highly prized for UHF systems that require very low loss at very high frequencies. The cable is like new, on a large wooden commercial roll, and has been stored in my barn completely out of any weather. The wooden "enclosure" is in good shape. Since I have no plans to use it, but need to clean out the barn, I'm offering it free of charge to anyone who comes and takes it. The cable roll will fit into any reasonably large trailer. It is too large for a normal pickup truck, however. If I get no requests for it, this whole length of very low loss 50 Ohm coax will go to the Hays County dump in a week or two. Please contact me at my email: n3bb(a)mindspring.com if interested. Please QSP this info to other radio clubs. Thanks and I sure hope that some serious UHFer of V-UHFer or even normal HFer can utilize this material. 73, Jim N3BB

The Kenwood D710GA is now in use. The crossband repeater is now available when the radio is not being used for ARISS school contacts. The frequencies are 145.99 MHz up (67 tone) and 437.800 MHz down. Watch the Doppler on the downlink. ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. ************************************************* ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates. The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools The ARISS webpage is at https://www.ariss.org/ Watch for future COVID-19 related announcements here also.

ARISS anticipates that the contact would be held between July 1, 2021 and December 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 deadline to submit a proposal is November 24th, 2020. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-fall-2020.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. Please direct any questions to ariss.us.education(a)gmail.com. For future 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. 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 ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org. ******************************************************************************** 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.

What I usually do is turn off Satellite Mode, then the radio becomes simplex at 145.825 (the frequency before I enable SatPC32). 73 de Yono - YD0NXX Sent from my iPhone > On Oct 14, 2020, at 8:40 PM, Stefan Wagener via AMSAT-BB <amsat-bb(a)amsat.org> wrote: >

for my setup I dont have to use SatPC32ISS, Using my FT847 in split mode I use SatPC32 and can use digi mode for ISS (all digi sats on 2m). I do have to adj slightly the up/down freq during the pass for doppler though. can then switch to other sats w/o using separate program. 73 Christy KB6LTY ------ Yes, it has to work in simplex mode on 145825 with SatPc32ISS 73, Stefan VE4SW On Wed, Oct 14, 2020 at 8:23 AM John Brier <johnbrier at gmail.com> wrote: > He can't switch between FM repeater and digipeater, or at least use the > digipeater with SatPC32, he needs SatPC32ISS for the digipeater, right? > > > http://sats.wikidot.com/how-do-you-add-add-2-meter-only-digipeaters-to-satp… > > 73, John Brier KG4AKV > > On Wed, Oct 14, 2020, 09:20 Stefan Wagener via AMSAT-BB < > amsat-bb at amsat.org> wrote: > >> Assuming you entered the different frequencies in the doppler.sqf file, in >> the main window click on "CAT" and select the frequency from the list in >> the box. >> >> 73 Stefan VE4SW >> >> On Wed, Oct 14, 2020 at 7:46 AM lu9cbl--- via AMSAT-BB < >> amsat-bb at amsat.org> >> wrote: >> >> > Hi to all! maybe someone can help me, i can´t find in google the answer. >> > >> > If i put the SatPC32 software to tracking the ISS, where i need to >> > select to switch for example for de ISS, to conmute from the APRS freq >> > to the FM repeater, and tracking that in my equipment? >> > >> > Thanks! >> > >> > Mati LU9CBL >> >
