I would second what Clint said. I've made several hundred contacts with a whip. I was lucky to make one contact in a pass. I built a tape-measure yagi and I can effortlessly make 4 to 5 contacts in a pass with it.

Support the CubeSat History Project
by Aaron Zucherman 22 Apr '24

22 Apr '24

Good day AMSAT community! We have an update for the Community on the progress of the CubeSat History Project! For those unfamiliar, Prof. Robert "Bob" Twiggs and a group of former students and colleagues are working on gathering and publishing a series of books on the history of the creation and adoption of the CubeSat. Take a look at the LinkedIn announcement here: https://lnkd.in/eNZgv6Tk If this sounds like something you'd be interested in supporting, please take a look at our GoFundMe page here: https://www.gofundme.com/f/cubesat-history-project The community's response has been amazing! Over a hundred interviews were conducted, and countless images and documents from the earliest days of the CubeSat were collected! The result is that we have accumulated one of the most comprehensive histories of the CubeSat, with many unique, never-before-told stories! Reach out if you are interested in sponsoring the project to get a signed copy and your organization's name in the book. Please email Dr. Aaron Zucherman at azucherman(a)gmail.com. As a bonus, please have a look at our book's cover art! [image: image.png] On behalf of Prof. Robert Twiggs and the entire team, Thank you for supporting our mission!

And be careful using longer/heavier antennas on your delicate SMA connector. Consider a adapter to make that SMA a BNC. I'd rather see you wear out a $15 adapter, then tear the center pin connection off the circuit board of your radio, requiring a radio replacement or a $60 repair job. High-quality SMA connectors are only rated at 3 to 500 connections, and lesser-expensive radios are not using high-quality SMA connectors.

I see that the TYT UV-8000E HT will do crossband repeat, which makes me think it will do full duplex as well. However, I can't find anything saying it does or doesn't do full duplex. Has anyone used this HT on the satellites and can you confirm or deny that it will do full duplex on the FM sats? 73 John AF5CC Sent using {0}

A single whip is obviously a compromise. The Smiley is a tri-band, but with specific whip extensions for specific bands. The 70 CM and the 2M lengths are different so there will be a compromise on the band that is not the band the antenna is set up for. I would probably have to make a decision as to whether to set this type of antenna for the RX band or the TX band. Resonance on TX means more power transferred to the antenna. Resonance on the RX band means better reception at the expense of RF out (Radio power foldback if SWR is too high).

Re: AO-109

Mark, Space-Track has a prediction for today, but not more specific. They seldom issue a final report of CubeSats though they will stop issuing new Keps. So, we need to use inference. Given the weak beacon, that is even trickier. Using the latest Keps, it should reenter around now, but with a wide range of time. One strong indicator is from the Status Page. EA6TA has regularly been reporting it was heard for the past few days. Today around 1430 UTC, he reported it was not heard. So it is likely down, or at the very least rendered inoperative by heat. Watch that page, just in case. 73, Alan WA4SCA From: Mark Johns, K0JM via AMSAT-BB <amsat-bb(a)amsat.org> Sent: Sunday, April 21, 2024 16:47 To: Kc2syf <kc2syf(a)gmail.com> Cc: AMSAT-BB <amsat-bb(a)amsat.org> Subject: [AMSAT-BB] Re: AO-109 Well, given that the last active report on that list is five days ago, I'd say that people aren't using it. -- Mark D.

A total of 9 of the submitted proposals during the recent proposal window have been accepted to move forward in the processes of planning to host a scheduled amateur radio contact with crew on the ISS. The primary goal of the ARISS program is to engage young people in Science, Technology, Engineering, Arts and Math (STEAM) activities and raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities. [ARISS News] The ARISS program anticipates that NASA will be able to provide scheduling opportunities for the 9 US host organizations during the July – December 2024 time period. They are now at work starting to implement their 4–6-month education plan which was outlined in their proposal. These STEAM based educational activities help prepare students for their contact as well as create an on-going exploration and interest in aerospace and amateur radio topics. They are also completing an acceptable equipment plan that demonstrates their ability to execute the ham radio contact. Once their equipment plan is approved by ARISS, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA. The schools and host organizations are: * Arizona Science Center, Phoenix, AZ * Bayou Academy, Cleveland, MS * Bishop O’Connell High School, Arlington, VA * Greenville Junior High School, Greenville, IL * Hillsboro Charter Academy, Purcellville, VA * Pacific Science Center, Seattle, WA * Sally Ride Elementary School, Orlando, FL * South Carolina Regional Workforce Advisors-Office of Statewide Workforce Development, Columbia, SC * TEACH-NW Charter School, Springfield, OR [ANS thanks Dave Jordan, AA4KN, for the above information.] ________________________________ [cid:[email protected]] The 2024 AMSAT President’s Club coins are here now!

The first quarter of the 2024 the President’s Club is off to a great start. With our regular dedicated contributors plus many first-time members, contributions have already raised almost $16,000 in the first three months of 2024. “So often, our members think about AMSAT’s having to raise funds for satellite hardware – the costs for electronic components, solar panels, batteries and so on. But, there are many background costs. A good example is software licenses needed for actual satellite development. The volunteer engineers can often swap licenses so they can limit the number of licenses needed. But, as they draw closer to finalizing drawings for circuit boards, spaceframes and deployable solar panels, the team can stretch software licenses only so far before work flow becomes handicapped. Some software licenses, even with the best educational or non-profit discounts, easily exceed the $1,000 mark. And, those licenses need to be renewed on an annual basis. “The engineering team can always use more electrical and mechanical engineers to move the FOX-PLUS and GOLF programs along. But, being able to leverage the efforts of our current volunteers with enough software licenses would be a huge plus. Contributions from members of the President’s Club make a big difference in giving the engineering team the tools they need.” To date, the generous donors members of the 2024 AMSAT President’s Club include: * Titanium ($4,800+) Barry Baines, WD4ASW William Brown, K9LF * Gold ($1,200+) Anonymous Burns Fisher, WB1FJ John Kludt, K7SYS Glenn Miller, AA5PK * Silver ($600+) Donald Coker, KM6TRZ Richard Dittmer, KB7SAT Mark Johns, K0JM Joseph, Lynch,N6CL Bruce Paige, KK5DO Jason Schwarz, N4JJS * Bronze ($300+) Donald Pettigrew, K9ECT Dave Taylor, W8AAS * Core ($120+) David Batzle, N2VDY Robert Beatty, WB4SON Alan Boggs, K7IIV James Gallagher III, KB3SQS David Hartrum, WA3YDZ Steven Husey, KB1UOJ William Pesci, N4WLP Paul Stoetzer, N8HM Stefan Wagener, VE4SW Wayne Wagner, AG1A Members can learn more about joining the President’s Club at https://www.amsat.org/join-the-amsat-presidents-club/.

[cid:[email protected]] When you purchase through AMSAT, a portion of the proceeds goes towards Keeping Amateur Radio in Space. https://amsat.org/product-category/hardware/ ________________________________ AMSAT Engineering Team Powering Up for Hamvention Given hams’ inherent interest in all things technical, it’s no wonder that the Engineering table at AMSAT’s Hamvention booth is always popular. Not wanting to disappoint our members, Jerry Buxton, N0JY, AMSAT VP- Engineering and his team are making plans for an informative and entertaining presence. No fewer than ten members of the engineering team will attending this year’s Hamvention. Probably the most interesting exhibit will be a full-scale model of the GOLF-TEE (Technology Exploration Environment) satellite. The 3-D model printed by team member Tom Karnauskas, N0UW, gives an interesting look at the challenges that satellite designers face when trying to fit stacks of circuit boards, bundles of batteries, attitude sensing and control systems, and experimental payloads inside a 10cm x 10cm x 30cm spaceframe. The model also gives a look at the challenge of adding deployable solar panels to the exterior of the spacecraft. Given the fact that the GOLF program represents AMSAT’s return to Highly Elliptical Orbit (HEO), engineers will no-doubt be busy answering questions on all facets of the GOLF program. Engineers will also be on hand to answer questions about the ongoing development of the Fox-Plus series of satellites. Recognizing the success of the original Fox series as an entry level introduction to amateur satellites, the engineers working the Fox-Plus birds are committed to improving on the original concept and setting the stage for future capabilities for these Low Earth Orbit (LEO) satellites. For those interested in a look even further into the future, engineers working the ASCENT program will also be present. ASCENT, meaning, Advanced Satellite Communication and Exploration of New Technology, is a “sandbox” for future satellite communications and related systems to be explored and pursued for eventual flight use. A radiation-tolerant internal-housekeeping-unit (RT-IHU), software defined radio (SDR) methods, and a 10 GHz PA design ideas are some ASCENT projects that will fly on GOLF-TEE. Engineers at the table can also discuss other ASCENT projects in the works such as a slow-scan television (SSTV) payload, a packet repeater payload and propulsion systems suitable for CubeSat operation.

Dr. Puig-Suari received B.S., M.S., and Ph.D. Degrees in Aeronautics and Astronautics from Purdue University. Dr. Puig-Suari is a professor emeritus in the Aerospace Engineering Department at Cal Poly, San Luis Obispo. In 1999, Dr Puig-Suari and Prof. Bob Twiggs at Stanford developed the CubeSat standard. Dr. Puig-Suari’s team was responsible for the development of the standard CubeSat deployer (the P-POD) and has supported launches for over 130 CubeSats in the U.S. and abroad. More information on the workshop can be found at https://www.cubesatdw.org/. [ANS thanks cubesat.org for the above information.] * AMSAT-DL has announced planning for the Bochum Space Conference 2024 to be held September 20-22, 2024. AMSAT-DL is organizing a symposium, flea market and general meeting in the radome of the Bochum Observatory. The radome will once again be dedicated to satellite and space research. AMSAT Deutschland e.V. and the Bochum Observatory are taking the positive experience of the anniversary conference in 2023 as an opportunity to inform AMSAT members and other space enthusiasts about current and future prospects for national and international space projects with a varied program. As the Radom is also the location of ESA’s education office in Germany (esero Germany), they want to make the symposium even more attractive in future and at the same time focus even more on current European space travel. More information at https://amsat-dl.org/en/bochum-space-conference-2024/. [ANS thanks AMSAT-DL for the above information.] * Boeing’s CST-100 Starliner embarked on its last big road trip before its journey to the International Space Station next month. In the pre-dawn hours of Tuesday morning, the capsule and its service module made the slow trek from Kennedy Space Center to Space Launch Complex 41 on Cape Canaveral Space Force Station. The rollout of the vehicle, named Calypso, is another key step towards the Crew Flight Test (CFT) of the Starliner spacecraft, the first time that it will carry astronauts to and from the ISS. The mission’s crew, NASA astronauts Butch Wilmore and Suni Williams, KD5PLB, were on hand to witness the departure of their ticket to ride. [ANS thanks Spaceflight Now for the above information.] * A dead spacecraft the size of a truck ignites with plasma and pulverizes into dust and litter as it rips through the ionosphere and atmosphere. This is what happens to internet service satellites during re-entry. When the full mega-constellation of satellites is deployed in the 2030s, companies will do this every hour because satellite internet requires thousands of satellites to constantly be replaced. Recent research has led some physicists to believe that the space trash generated by dead and dying commercial satellites could compromise our ionosphere or magnetosphere. Unlike meteorites, which are small and only contain trace amounts of aluminum, these wrecked spacecraft are huge and consist entirely of aluminum and other exotic, highly conductive materials. And highly conductive materials can create charging effects and act as a magnetic shield.

If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-04-19 20:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-04-19 04:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## 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. Watch for future COVID-19 related announcements at https://www.ariss.org/ 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/ Note that there are links to other ARISS websites from this site.

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.
