ARISS anticipates that the contact would be held between January 1, 2022 and June 30, 2022. 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 March 31st, 2021. 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 February 25th, 2021 at 8 PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-spring-2021.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.

ND9M/MM - FL16 and/or FL25
by Clary, James T (Jim) 14 Apr '21

14 Apr '21

We've got great sailing weather although it's a bit windy on the flight deck where I operate. The ship's forward speed coupled with a tough crosswind made tonight's operating real tricky because I had to hold everything down and still manage the key! But RS-44 was a success by using CW. I couldn't hear the bird for beans on SSB, so tonight's CW run was encouraging. I'm hearing the U/V satellites a bit better than RS-44, but am still not doing well on those, so I may bring CW on the XW sats at some point. I was in a bunch of these grids a while back, and I know UT1FG has done a bunch of them too, so the next few days before the Canal will tell the story. The rarer ones are on the Pacific side, and I'd rather get these wet grids into several logs using CW instead of no logs at all on SSB. Tomorrow's route is a southeast diagonal that will take us through FL16 and into FL25. (We'll hit the quad corner with FL15 and FL26, but unfortunately we can't stop for important stuff like grid squares!) I should be on XW-2A/D/F, AO-27, and RS-44/CW.

DC Switch for M2 Polarization Antenna Switch
by BeetleJerald Oliver 13 Apr '21

13 Apr '21

Just wondering if anyone has ever devised a 12 Volt DC Switch console at the operating position to send 12V to the Polarization switches on the CP yagis at the tower? would toggle switches be okay for that or should I use relays instead? Also like to use LED indicators for visual settings...... Any thoughts ? 73 Jerry KJ4EU

ND9M/mm - FL09 -> FL16
by Clary, James T (Jim) 13 Apr '21

13 Apr '21

My ship will be leaving EM90 tomorrow (4/13) to head for the western Pacific. We'll probably hit FL09 around 14/0000Z (maybe a little earlier). This is a working trip for me, but I'm planning to be on the XW-2A/D/F and AO-27. I'm having a heck of a time hearing the RS-44 downlink, so I'll plan on being on that bird's two passes tomorrow evening, but on CW. The voyage plan has us in FL15 or FL16 late afternoon (LT) on the 14th and into FL25 that evening. We'll turn south shortly after that. Thanks to Hector/W5CBF, Curt/K7ZOO, and Fernando/KF7R for their help with SatPC32.

Please send any amateur satellite news or reports to: ans-editor(a)amsat.org You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ In this edition: * ARISS-USA Now a Non-profit Organization * Contests On QO-100 Allowed In Time For Yuri Gagarin Contest * Fun While It Lasted, Falcon 9 Telemetry Now Encrypted * AMSAT SA Call For Papers * NASA Invites Public to Take Flight With Ingenuity Mars Helicopter * Changes to AMSAT-NA TLE Distribution for April 8, 2021 * Busy month of crew rotations on tap at International Space Station * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over ANS-101 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 101.01 To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE Suite 1653 Washington, DC 20002 DATE 2021 April 11 ARISS-USA Now a Non-profit Organization ARISS-USA, a Maryland not-for-profit corporation, is now recognized by the United States Internal Revenue Service as a Section 501(c)(3) charitable, scientific, and educational organization. ARISS-USA is the US segment of the ARISS (Amateur Radio on the International Space Station) international working group. With this IRS determination, donations to ARISS-USA become tax-deductible in the US, retroactive to the ARISS-USA incorporation on May 21, 2020. This change in status allows ARISS-USA to solicit donations and grants. As a new entity, ARISS-USA will continue to promote student involvement with the astronauts on the International Space Station via amateur radio. Working with educational organizations, ARISS provides exciting opportunities to inspire, engage and educate our next generation of space explorers through STEAM (science, technology, engineering, arts and math) activities and content. ARISS-USA Executive Director, Frank Bauer, commented, “The educational scope and reach of what ARISS accomplishes has grown significantly since our beginnings in 1996. We are actively working to extend student’s reach even further. This, through the pursuit of potential student opportunities on human spaceflight missions beyond low Earth orbit, as part of our Amateur Radio Exploration (AREx) Program. First AREx destination: the Moon!” ARISS-USA continues its collaborative work with ARISS International and US sponsors, partners, and interest groups. The ARISS-USA TEAM remains deeply indebted to its partners ARRL and AMSAT, who enabled the birth of ARISS, and to its steadfast sponsors, NASA Space Communication and Navigation (SCaN) and the ISS National Lab (INL). Gifts from those wishing to support ARISS-USA goals are tax-deductible to the extent allowed by law and can be made by going to the ARISS website: www.ariss.org The ARISS-USA team thanks its sustaining donors for their continuing support!

QO-100 is a Qatari satellite, launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. It operates at 26° East longitude along a geostationary orbit, which means that the satellite's footprint covers Europe, Africa, and Asia, but excludes North America and most of South America. This weekend (April 10-11) will see the Yuri Gagarin contest. The contest area on the QO-100 geostationary satellite NB transponder for both CW and SSB is: Uplink area 2400.370 – 2400.490 MHz Downlink area 10489.870 – 10489.990 MHz Of course, the usual QO-100 NB transponder guidelines also apply here. Therefore, the bandwidth should still be limited to 2.7 kHz and the transmitting power should be reduced to the necessary level, i.e. only as much power as necessary should be used. Read the AMSAT-DL announcement at https://amsat-dl.org/en/contests-on-qo-100-allowed/ The Yuri Gagarin International DX Contest 2021 is dedicated to the memory of Yuri Gagarin, who realized the first human flight to space, on April 12, 1961.

With further software fiddling, the vehicle’s video streams were decoded, resulting in some absolutely breathtaking shots of the rocket and its payload from low Earth orbit. Unfortunately, it looks like those heady days are now over, as [derekcz] reports the downlink from the latest Falcon 9 mission was nothing but unintelligible noise. Since the hardware and software haven’t changed on his side, the only logical conclusion is that SpaceX wasn’t too happy about radio amateurs listening in on their rocket and decided to employ some form of encryption.

The back-to-back crew rotations will make for a busy month on the orbiting research complex, and multiple instances when ARISS operation will be suspended during crew operations. Preparations for the arrival of the fresh crew members are already underway on the space station. The first step was relocation of a SpaceX Crew Dragon spaceship to a new docking port on the space station April 5. NASA astronaut Mike Hopkins, KF5LJG, commander of the Crew Dragon “Resilience” spaceship, was joined by crewmates Victor Glover, KI5BKC, Soichi Noguchi, KD5TVP, and Shannon Walker, KD5DXB, for the fully automated 45-minute relocation maneuver. The Dragon astronauts, who launched Nov. 15 as part of SpaceX’s “Crew-1” mission, were aboard the Crew Dragon Resilience spacecraft and suited up for re-entry, just in case the capsule had trouble linking up with the new docking port and needed to return to Earth. Next was the launch of a Russian Soyuz MS-18 spacecraft with commander Oleg Novitskiy, cosmonaut Pyotr Dubrov, and NASA astronaut Mark Vande Hei, KG5GNP. The Soyuz crew launched from the Baikonur Cosmodrome in Kazakhstan on Friday, April 9 at 3:42 a.m. EDT (0742 GMT). The crew on the space station will temporarily swell to 10 people until the outgoing Soyuz MS-17 crew departs the research lab one week later. Undocking of the Soyuz MS-17 spacecraft with commander Sergey Ryzhikov, flight engineer Sergey Kud-Sverchkov, and NASA astronaut Kate Rubins, KG5FYJ, is scheduled for 9:33 p.m. EDT on April 16 (0133z on April 17). The Soyuz capsule is scheduled to parachute to a landing on the steppes of Kazakhstan at 12:56 a.m. EDT (0456 GMT) on April 17. Ryzhikov, Kud-Sverchkov, and Rubins launched Oct. 14 from Baikonur. Their return to Earth on April 17 will wrap up a 185-day mission. With the Soyuz crew rotation complete, SpaceX and NASA will be cleared to launch the second operational Crew Dragon mission to the space station on April 22. NASA astronaut Shane Kimbrough, KE5HOD, pilot Megan McArthur, Japanese astronaut Akihiko Hoshide, KE5DNI, and French-born European Space Agency astronaut Thomas Pesquet, KG5FYG, will fly on the Crew-2 mission. Assuming the Crew-2 mission takes off April 22, Kimbrough and his crewmates will reach the space station for an automated docking at 5:29 a.m. EDT (0929 GMT) on April 23. Their arrival will start a five-day handover with the Crew-1 astronauts, when the space station will briefly host 11 crew members. The Crew-1 astronauts are scheduled to board their Crew Dragon Resilience spacecraft and undock from the space station April 28 at 5 a.m. EDT (0900 GMT). The Crew Dragon capsule will fire its Draco thrusters to target a parachute-assisted splashdown off the coast of Florida at 12:35 p.m. EDT (1635 GMT) the same day.

Possible "Rover" Operation from DM76 and possibly from DM 86
by hamdan＠ix.netcom.com 11 Apr '21

11 Apr '21

Dear Folks: In a couple of weeks, I am leaving for the summer to work as a seasonal ranger for the National Park Service at Capulin Volcano National Monument. The only ham equipment I am taking with me is that which is suitable for portable operation, i.e., an Elecraft K2 with a Buddipole, and I have an Alinco DJ-G5T with an Arrow Antenna. Capulin is located either in DM 76 or DM 86 (more likely the former) as it really is in an isolated spot. I've made several thousand satellite QSO's over the years but only one using the HT with the Arrow. Most of the time, I've used my FT-736R (recently replaced by an IC 9700 to M2 CP antennas on the roof with preamps). If I get on the birds using this setup, I'll be confined to (considering the current lineup of FM birds) SO-50, AO-27 and maybe AO-91 (if it keeps operating in daylight). I have a few questions that I'm hoping that you can help me with. 1) I am assuming that DM76 and DM 86 are desireable grids? I certainly don't have them. 2) I know a lot of portable operators record their passes for logging purposes later. Is the voice memo recorder on my iPhone sufficiently sensitive, particularly to pick up both ends of the QSO? 3) I have been uploading to LOTW for several years now. How accurate does the time entered into the log have to be to ensure a mutual confirmation on LOTW? In other words, do I have to have it within +/- 5 minutes? I'm just thinking that I won't be able to be very precise with the time of a QSO if I'm relying on a recording. 4) Are there any other suggestions people might have for me given my planned setup? I would try and announce my presence prior to a pass via this board, but my internet access (I'll be living in the park) will be spotty. Thanks for any help and advice you can give me. 73 de Bernie, KF0QS

M2 LEO Pack 70CM antenna polarization
by Don Solberg 09 Apr '21

09 Apr '21

I am assembling my new LEO pack, and the instruction manual for the 2M antenna tells you that you can change from RHCP to LHCP by repositioning the driven element and phase line. The 70CM antenna however does not have this ability explained in the manual. I have asked this question of M2 but haven't heard back yet. If possible, I would like to have the 2M antenna configured for RHCP and the 70CM for LHCP to minimize any desensing. The antennas will be up about 80 ft on top of my tower, so I would like to get this configured correctly the first time so I don't have to bring the tower down. Does anyone have any experience changing the polarization on the M2 70CM antenna in the LEO Pack? 73, Don K9AQ
