AMSAT Demonstration Station at the Dayton Hamvention Recap
This was my first year running the AMSAT demonstration station at the Dayton Hamvention after Keith Pugh, W5IU, had run it for many years. After volunteering at the demo station the past couple of years, I knew what to expect: a poor horizon to the north (due to the arena), high levels of RF (including lids running FM simplex inside the satellite subband on 2m), and lots of fun demoing satellite operation to curious newcomers as well as meeting many satellite operators I've worked on the satellites in person.
The core of the demo station was similar to past years. I brought my pair of Yaesu FT-817s (known fondly among many satellite operators as a Yaesu FT-1634) as well as a Windows 10 tablet and a FUNcube Dongle Pro+. The antenna was an Arrow II 146/437-10BP and I also brought a cheap Optera camera tripod. In addition, John Papay, K8YSE, brought his Icom IC-910H, laptop, and Arrow antenna on a speaker stand with a mount that allowed a smooth way to change polarity throughout the pass. With this mix of equipment, we were able to demonstrate several methods of satellite operating: computer controlled Doppler tuning of a transceiver designed for satellite operating, manual Doppler tuning with a pair of VHF/UHF all-mode transceivers, and use of an SDR receiver with a VHF/UHF all-mode receiver for full-duplex operating on linear transponders.
The demo area was up and running by the time the outdoor areas of the Hamvention opened at 8:00am on Friday morning. Our first pass was an XW-2A pass at 8:17am, with K8YSE operating his IC-910H and KD8CAO running the antenna. The demos were generally a two man operation with one operator at the radio and one serving as the antenna rotor. After this pass, we listened to the 70cm PSK31 signal from NO-84 and a few packet bursts from the ISS using the FUNcube Dongle Pro+ and Windows 10 tablet before a pair of AO-85 passes and an XW-2F pass operated by K8YSE.
By special request, the AO-73 transponder was activated a day area and was available for Friday morning's demos. I operated the 10:51am pass with my pair of Yaesu FT-817s. A video of this pass is available on the AMSAT North America Facebook page: https://www.facebook.com/groups/7828379515/permalink/10154235785829516/
Later, I operated an SO-50 and FO-29 pass with that pair of FT-817s as well, but had to fight strong desense. After those two passes, I grabbed a diplexer I had brought and placed it on the 2m transmit side (to filter out the third harmonic from the transmitter) and experienced no further desense problems with my setup. PY5LF captured part of the SO-50 pass on video: https://www.youtube.com/watch?v=wVPb1a9NqxQ K8YSE then operated the rest of the FO-29, AO-7, and SO-50 passes that afternoon.
On Saturday morning, we opened with listening (and decoding a bit) to the PSK31 beacon on NO-84. Unfortunately, we did not have HF transmit capability. The signal from NO-84's PSK31 transponder is very good and I highly recommend anyone who can transmit on 10m at 25-50 watts and receive a 70cm FM signal give it a try.
After working an XW-2F pass with the pair of FT-817s, I decided to give the SDR receiver a try and made one QSO each on XW-2C and XW-2A using the SDR as a downlink receiver. This was the first time I had tried doing this and it was fun, though I definitely need some more practice with it! I also tried the SDR receiver on AO-73 and FO-29 and made a couple of QSOs.
Shortly after the ARRL Youth Forum ended around noon, a large crowd began to arrive at the demo area. Nine-year old Hope Lea, KM4IPF, who had given a talk at the Youth Forum operated a pass of SO-50 around 12:19pm and made many QSOs from coast-to-coast. A video of this pass is available from the AMSAT North America Facebook page: https://www.facebook.com/james.g.lea/videos/10154297928734363/
After the SO-50 pass, we made several QSOs on FO-29 and then listened to the SPROUT digitalker. The SPROUT digitalker is generally active on Saturday passes. A video of this pass is available here: https://www.youtube.com/watch?v=4FRNZkMb5yM
K8YSE then operated the Saturday afternoon passes of FO-29, AO-7, and AO-85 with his Icom IC-910H setup. Highlights included several of us passing around the microphone to work Paulo, PV8DX, in Brazil.
We got an early start on Sunday morning, operating a pass of AO-85 to the northeast using my dual FT-817 setup just prior to 8:00am. Although I was the only person in the demo area, I made three QSOs on AO-85, holding the antenna myself and leaning over the table to operate the radio. After this, I operated a pass of XW-2F around 8:30am. For the 8:44am XW-2A pass, ARRL Media & Public Relations Manager Sean Kutzko, KX9X, took the microphone and made several QSOs on that pass while I pointed the antenna. Although I did have a tripod for the antenna, I was simply using the stock camera tripod mount and had no way to adjust polarity. Since polarity is so critical while operating satellites, the operators who pointed the antenna while using my Arrow generally took the antenna off the tripod and held it in their hand for quick polarity adjustments. K8YSE's speaker stand mount demonstrated a good way to mount an Arrow antenna on a tripod while retaining adequate control over polarity.
The next pass after this was a low western pass of XW-2C where I made several QSOs. At 9:37am, we operated a pass of AO-85 and made QSOs from coast-to-coast. A video of AMSAT VP of Operations Drew Glasbrenner, KO4MA, at the microphone is available at: https://www.youtube.com/watch?v=xrmzym39X5E
I would note that we were using a pair of FT-817s, barefoot, on that pass and were able to make several QSOs with just 5 watts, mostly full quieting. Though AO-85 can often take a bit more power to get in to, QSOs using 5 watts and an Arrow antenna are very possible.
Passes of SO-50, AO-73, and FO-29 rounded out the demos for the Hamvention and we were QRT at 12:12pm on Sunday, but not before working MI6GTY in Northern Ireland on FO-29. It was nice to get Europe in the log from the Dayton Hamvention demo station and it was our last QSO of the 2016 Hamvention.
The AMSAT demo station has been a fun place to spend a majority of the last three Dayton Hamventions and I would encourage all satellite operators and those curious about satellite operation to visit the station outside of Ball Arena (near the ARRL and AMSAT booth areas) next May. Volunteers and guest operators are always sought!
A few pictures are posted on the AMSAT North America Facebook page: https://www.facebook.com/groups/7828379515/permalink/10154235785829516/ (The AMSAT North America Facebook group is very active - in fact, traffic has likely surpassed the traffic on the AMSAT-BB.

A Tiny Satellite of Your Very Own
They're not just for rocket scientists anymore
Satellites used to be the exclusive playthings of rich governments and wealthy corporations. But increasingly, as space becomes more democratized, these sophisticated technologies are coming within reach of ordinary people. Just like drones before them, miniature satellites are beginning to fundamentally transform our conceptions of who gets to do what up above our heads.
As a recent report from the National Academy of Sciences highlights, these satellites hold tremendous potential for making satellite-based science more accessible than ever before. However, as the cost of getting your own satellite in orbit plummets, the risks of irresponsible use grow.
The question here is no longer “Can we?” but “Should we?” What are the potential downsides of having a slice of space densely populated by equipment built by people not traditionally labeled as “professionals”? And what would the responsible and beneficial development and use of this technology actually look like?
Some of the answers may come from a nonprofit organization that has been building and launching amateur satellites for nearly 50 years. Just a few inches across and ready for orbit.
The technology we’re talking about
Having your own personal satellite launched into orbit might sound like an idea straight out of science fiction. But over the past few decades a unique class of satellites has been created that fits the bill: CubeSats.
The “Cube” here simply refers to the satellite’s shape. The most common CubeSat (the so-called “1U” satellite) is a 10 cm (roughly 4 inches) cube, so small that a single CubeSat could easily be mistaken for a paperweight on your desk. These mini, modular satellites can fit in a launch vehicle’s formerly “wasted space.” Multiples can be deployed in combination for more complex missions than could be achieved by one CubeSat alone.
Within their compact bodies these minute satellites are able to house sensors and communications receivers/transmitters that enable operators to study the Earth from space, as well as space around the Earth.
They’re primarily designed for Low Earth Orbit (LEO) – an easily accessible region of space from around 200 to 800 miles above the Earth, where human- tended missions like the Hubble Space Telescope and the International Space Station (ISS) hang out. But they can attain more distant orbits; NASA plans for most of its future Earth-escaping payloads (to the moon and Mars especially) to carry CubeSats.
Because they’re so small and light, it costs much less to get a CubeSat into Earth orbit than a traditional communication or GPS satellite. For instance, a research group here at Arizona State University recently claimed their developmental “femtosats” (especially small CubeSats) could cost as little as US$3,000 to put in orbit. This decrease in cost is allowing researchers, hobbyists and even elementary school groups to put simple instruments into LEO, by piggybacking onto rocket launches, or even having them deployed from the ISS.
The first CubeSat was created in the early 2000s, as a way of enabling CalPoly and Stanford graduate students to design, build, test and operate a spacecraft with similar capabilities to the USSR’s Sputnik.
Since then, NASA, the National Reconnaissance Office and even Boeing have all launched and operated CubeSats. There are more than 130 currently operational in orbit. The NASA Educational Launch of Nano Satellite (ELaNa) program, which offers free launches for educational groups and science missions, is now open to U.S. nonprofit corporations as well.
Clearly, satellites are not just for rocket scientists anymore.
Thinking inside the box
The National Academy of Sciences report emphasizes CubeSats' importance in scientific discovery and the training of future space scientists and engineers. Yet it also acknowledges that widespread deployment of LEO CubeSats isn’t risk- free.
The greatest concern the authors raise is space debris – pieces of “junk” that orbit the earth, with the potential to cause serious damage if they collide with operational units, including the ISS.
Currently, there aren’t many CubeSats and they’re tracked closely. Yet as LEO opens up to more amateur satellites, they may pose an increasing threat. As the report authors point out, even near-misses might lead to the “creation of an onerous regulatory framework and affect the future disposition of science CubeSats.”
More broadly, the report authors focus on factors that might impede greater use of CubeSat technologies. These include regulations around earth-space radio communications, possible impacts of International Traffic in Arms Regulations (which govern import and export of defense-related articles and services in the U.S.), and potential issues around extra-terrestrial contamination.
But what about the rest of us? How can we be sure that hobbyists and others aren’t launching their own “spy” satellites, or (intentionally or not) placing polluting technologies into LEO, or even deploying low-cost CubeSat networks that could be hijacked and used nefariously?
As CubeSat researchers are quick to point out, these are far-fetched scenarios. But they suggest that now’s the time to ponder unexpected and unintended possible consequences of more people than ever having access to their own small slice of space. In an era when you can simply buy a CubeSat kit off the shelf, how can we trust the satellites over our heads were developed with good intentions by people who knew what they were doing?
Some “expert amateurs” in the satellite game could provide some inspiration for how to proceed responsibly.
Guidance from experienced amateurs
In 1969, the Radio Amateur Satellite Corporation (AMSAT) was created in order to foster ham radio enthusiasts' participation in space research and communication. It continued the efforts, begun in 1961, by Project OSCAR – a U.S.-based group that built and launched the very first nongovernmental satellite just four years after Sputnik.
As an organization of volunteers, AMSAT was putting “amateur” satellites in orbit decades before the current CubeSat craze. And over time, its members have learned a thing or two about responsibility.
Here, open-source development has been a central principle. Within the organization, AMSAT has a philosophy of open sourcing everything – making technical data on all aspects of their satellites fully available to everyone in the organization, and when possible, the public. According to a member of the team responsible for FOX 1-A, AMSAT’s first CubeSat:
This means that it would be incredibly difficult to sneak something by us … there’s no way to smuggle explosives or an energy emitter into an amateur satellite when everyone has access to the designs and implementation.
However, they’re more cautious about sharing info with nonmembers, as the organization guards against others developing the ability to hijack and take control of their satellites.
This form of “self-governance” is possible within long-standing amateur organizations that, over time, are able to build a sense of responsibility to community members, as well as society more generally.
How does responsible development evolve?
But what happens when new players emerge, who don’t have deep roots within the existing culture?
Hobbyist and student “new kids on the block” are gaining access to technologies without being part of a longstanding amateur establishment. They are still constrained by funders, launch providers and a tapestry of regulations – all of which rein in what CubeSat developers can and cannot do. But there is a danger they’re ill-equipped to think through potential unintended consequences.
What these unintended consequences might be is admittedly far from clear. Certainly, CubeSat developers would argue it’s hard to imagine these tiny satellites causing substantial physical harm. Yet we know innovators can be remarkably creative with taking technologies in unexpected directions. Think of something as seemingly benign as the cellphone – we have microfinance and text- based social networking at one end of the spectrum, improvised explosive devices at the other.
This is where a culture of social responsibility around CubeSats becomes important – not simply for ensuring that physical risks are minimized (and good practices are adhered to), but also to engage with a much larger community in anticipating and managing less obvious consequences of the technology.
This is not an easy task. Yet the evidence from AMSAT and other areas of technology development suggest that responsible amateur communities can and do emerge around novel technologies.
For instance, see the diy-bio community, where hobbyists work in advanced community biotech labs. Their growing community commitment to safety and responsibility is highlighting how amateurs can embrace responsibility in research and innovation. A similar commitment is seen within open-source software and hardware communities, such as the members of the Linux Foundation.
The challenge here, of course, is ensuring that what an amateur community considers to be responsible, actually is. Here’s where there needs to be a much wider public conversation that extends beyond government agencies and scientific communities to include students, hobbyists, and anyone who may potentially stand to be affected by the use of CubeSat technology.

UWE-3 Status Report
On May 21, 2016 the CubeSat UWE-3 celebrated 2.5 years in space without any significant failures.
Batteries, EPS, OBC and ADCS are fine, nevertheless we were confronted with a minor problem with one of the radios UWE-3 autonomously recovered from. Since then UWE-3 is in a very stable condition again.
Some weeks ago we have re-initiated operations with UWE-3 on an interim basis. The goal is to test new magnetic control algorithms in space. Therefore we operate the satellite on the 436.395200 MHz frequency and perform data downloads from time to time. In the figure below the satellite’s rotation rate w is shown for one of the experiments. The goal was to establish a rotation about the satellite’s X-axis at 10 deg/s while the Y/Z-axes should be at 0 deg/s. In general the desired rotation rate could be achieved but with major deviations from the setpoint. With the intention of optimizing the relevant control laws we will continue with these experiments within the next days and weeks.
During our experiments we received an outstanding support from the radio community from all over the world we are very thankful for. The received packets were instantaneous injected into our algorithms and delivered an important contribution to our research work. We would like to express our special thanks to DK3WN, PE0SAT, DL8MCO, EU1XX, ON4HF, Rainer, JA5BLZ, JA6PL, CU2JX, LU4EOU, JA1GDE, SP7THR, G7GQW, YC3BVG, JF1EUY, JE9PEL, JE1CVL, JO1PTD, ZL4JL, EA7ADI, K4KDR, JA0CAW, JH4XSY, PA2EON, SM0TGU. THANK YOU!
UWE-3 was launched with FUNcube-1 on November 21, 2013. Latest UWE-3 news at http://www7.informatik.uni-wuerzburg.de/forschung/space_exploration/projects /uwe_3/uwe_3_news/

Tomsk-TPU-120 CubeSat Video
The Russian space agency Roscosmos has released a video of the Tomsk-TPU-120 CubeSat commemorative transmission from the International Space Station.
The satellite was developed by students at the Tomsk Polytechnic University to test new space materials technology and is the world’s first space vehicle with a 3D-printed structure. It was launched from Baikonur to the ISS on March 31, 2016 in a Progress-MS-2 cargo vessel. It will be deployed by hand during a future Russian spacewalk (EVA), which is why unlike other CubeSats this one has a handle. The call sign of the satellite is RS4S.
Tomsk-TPU-120 CubeSat Callsign RS4SIn May 2016 the Tomsk Polytechnic University celebrated its 120th anniversary. As part of the celebrations on May 10/11 the Tomsk-TPU-120 was activated in the ISS and transmitted a greeting to Earth inhabitants, recorded by students of the university in 10 languages: Russian, English, German, French, Chinese, Arabic, Tatar, Indian, Kazakh and Portuguese.
The greeting message was transmitted once a minute on 437.025 MHz FM. One of the Kenwood transceivers on the ISS provided a cross-band relay, re- transmitting the signal on 145.800 MHz FM.
The video, recorded in the Russian ISS Service Module, shows the CubeSat and the amateur radio station. The video is in Russian.
The next Russian spacewalk appears to be EVA-43 which is expected to take place in early 2017 http://spaceflight101.com/iss/iss-calendar/

ÑUSAT-1 SSB/CW Transponder Satellite
The launch of ÑUSAT-1, the second AMSAT ARGENTINA amateur satellite on May 30, will mark an extraordinary event for our Institution and fostering of hope for satellite community.
As we quoted when the announcement of the launching of this experiment, Amsat Argentina has been working for several years to keep alive the dream of many Argentine amateurs to get back into Space with their own satellite as a follow- on of the legendary 1990’s LUSAT-1, reaping the benefits of Technological advancement of our days.
We believe technical activities and developments of experiments in near space share the same goals: preserving the human group, enhancing their capabilities as well as disseminate and guiding the education and development of the activity, meanwhile contributing to Space available resources.
Our agreement with Satellogic Enterprises, which already launched three low orbit satellites: Captain Beto, Manolito y Tita, two of which transmit telemetry and data currently in UHF identifying themselves with callsign LU7AA, allowed us to ride a linear analog amateur radio transponder and corresponding antenna aboard one of their next satellite, ÑUSAT-1
AMSAT-LU provides simultaneously, support for this mission and the ÑUSAT-2 mission, by operating one of the control stations at Tortuguitas, Prov. Of Bs.As.
The experiment Amsat-LU developed, evolved from original design of our colleague and partner William, PE1RAH, while electronic adaptation, mechanical and software was made by the LU Satellite Experiment group, mounted on a 10 x 10 centimeters radiating plate, in which components of the power supply as well as a duplexer and dual band antenna where also incorporated.
This set was installed on the Ñusat-1 bus, which supplies power and becomes part of several other experiments this satellite will make.
The transponder receives UHF which is broadcasted in VHF, has a bandwidth of 30 kHz. with an output power of 250 mW.
435.935 ~ 435.965 are LSB/CW uplink passband 145.965 ~ 145.935 are USB/CW downlink passband 145.900 Basic CW Telemetry
The launch will be from a Chinese launcher in a polar orbit at 500 km. height, with inclination of 97 degrees from Equator.

ESA Announces Winning Radio Amateurs
On April 21, 2016, ESA’s Education Office set a challenge for the worldwide radio amateur community to start listening out for three new orbiting CubeSats. The results have now been released.
ESA’s Education Office published the transmission frequencies of the student- built satellites that were about to be launched as part of the Fly Your Satellite! Program, and invited the radio amateur community to listen out for them.
The first three radio amateurs to send a recorded signal from AAUSAT4, e-st@r- II or OUFTI-1 would receive a prize from ESA’s Education Office. Hundreds of radio amateurs from around the world joined in the friendly competition.
The CubeSats started sending signals after their release from the Soyuz VS-14 rocket and the triggering of their automatic activation sequence. Participants from Russia, USA, Poland, France, Belgium, Netherlands, Brazil, Italy, Denmark, and more tuned their receivers and listened.
Thanks to skill and patience on the ground, the winners come from Russia, the United States of America, Germany, and the Netherlands.
Contact with the first CubeSat came at 00:53:51 UT on April 26, 2016, within an hour of its separation from the launcher. Dmitri Paschkow R4UAB, Russia, heard the signal from OUFTI-1 using two receiving stations, in Kemerovo and Ruzaevka. Upon hearing OUFTI-1, he communicated the news immediately. “I understand that the students are worried [to hear from their satellite] and decided to please them!” says Paschkow.
Just over an hour after the first signal from OUFTI-1 was recorded, the next CubeSat checked in.
AAUSAT-4 was heard over California, US, by Justin Foley KI6EPH of California Polytechnic State University. He had a personal interest in the mission because some of his colleagues had developed the P-POD deployer that was used to eject the CubeSats into orbit.
He was ready at the receiver from the moment of deployment but heard nothing on that first pass, probably because the activation sequence had not yet completed. The signal came through on the second pass, arriving at 02:02 UT.
“It was extremely exciting to see signals from the newly launched satellite, and witness the beginning of a space mission”, says Foley.
Then the wait began for e-st@r-II. At 05:40:58 UT, something dimly lit the screen of Mike Rupprecht DK3WN in Germany. But something was not quite right. It certainly looked like a signal from the last remaining CubeSat, but why was the message so faint? It galvanized the amateur radio community to look harder.
Jan van Gils PE0SAT had to wait until May 2 at 16:38:05 UT to receive a signal from e-st@r-II that was strong enough to be decoded. Why e-st@r-II was only transmitting weak signals is under investigation, but the most important news is that all three CubeSats are functioning and transmitting, and their signals can be decoded.
A special mention goes to a young radio amateur who scored a personal best. Twelve year-old space enthusiast Matteo Micheletti from Belgium caught the OUFTI-1 signal with a portable log periodic antenna and a portable receiver. His triumph occurred on May 1, 2016 between 17:34 and 17:39 UT.
To mark their success, the radio amateur winners will each receive a Fly Your Satellite! Poster, a goodie bag and a scale 1:1 3D printed model of a CubeSat from ESA’s Education Office.
