Re: [amsat-bb] Duchifat3 FM transponder?

Yes we have been discussing this on twitter. It was successfully launched yestorday by ISRO and shortly after it was heard by Glenn AA5PK and a few others over the US on 436.420 with the FM repeater active. As of today the FM repeater is not on, only 9600 baud telemetry. So very good sign the satellite is functioning well. There's also a good chance that the repeater will be active continuously rather on a schedule as they said all 3 of its payloads will operate in "parallel" Frequencys: Downlink: 436.420 (stated 436.400 but it's been heard 20khz above the published frequency for some reason) Uplink: 145.970 no tone Status as of this post: 9K6 telemetry only. Preliminary TLE (not 100% accurate but close) allegedly could be object 2019-089B DUCHIFAT-3 1 84101U 19345.41319444 .00000000 00000-0 50000-4 0 08 2 84101 37.0000 148.0000 0001442 0.0000 140.0000 15.02563222 03 73 Nick KE8AKW

FW: Questions on USNA Satellite Identifications
by Robert Bruninga 13 Dec '19

13 Dec '19

Although we have lost the PSAT-2 VHF downlink, the UHF PSK31 and SSTV camera are still on 435.350. We have been asked by authorities to confirm that PSAT2 is correctly catalogued as 44354? (I believe it is) Similarly, USNAP1 is still beaconing once a minute on 145.825. They are asking if it could be 44357 (OBJECT U) instead of 44355 Having moved out of our lab/groud station of 27 years we have no antennas and cannot easily do this until the spring. Thanks Bob, WB4APR

I'm going to try AO-92 in ~ 1/2 hour from FN44, my contest station. No elevation, but we'll see how it goes. Sorry for the short notice.... Mike, N1JEZ FN44ar VT

TLEs for ATL 1 and SMOG-P
by Nico Janssen 13 Dec '19

13 Dec '19

Apparently it is not easy for18 SPCSto determine accurate TLE sets for the PocketQubes in the 2019-084 launch. This is understandable, given their small size of only 5 cm. Therefore I determined the TLE sets for ATL 1 (44830) and SMOG-P (44832) myself, using accurate doppler measurements. These should (initially) be accurate within a few seconds. ATL 1 1 44830U 19084G 19346.85945000 .00001000 00000-0 50000-4 0 08 2 44830 96.9998 211.0781 0044791 228.7076 277.5196 15.64736264 09 Frequency: 437.1741 MHz. SMOG-P 1 44832U 19084J 19346.85910300 .00001000 00000-0 50000-4 0 05 2 44832 97.0009 211.0657 0089111 218.3064 289.3286 15.64885322 06 Frequency: 437.1497 MHz. 73, Nico PA0DLO

Green Heron RT-21 AZ/EL rotor controller
by Jeff kb2m 13 Dec '19

13 Dec '19

I’m looking to buy a Green Heron RT-21 AZ/EL rotor controller to replace the one that came with my Alfa Spid AZ/EL RAS. Every time I move back here for the winter I end up taking apart and fixing the Rot2pro G that came with the Spid rotor. If any one that has one I would like your opinion, Thanks… 73 Jeff kb2m

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. 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.
