AO-92 QRM
by Dave Pascoe 04 May '20

04 May '20

I witnessed the AO-92 QRM again on the 0100Z pass today (Sunday night). The source of the QRM seems to be related to the Gloucester, MA area. A net was taking check-ins at 9PM EDT and I heard at least 2 or 3 stations check in. One of the stations, I believe, was on Echolink, so it is probably the 145.13 Gloucester, MA that is part of the issue. I suspect it is some sort of UHF/VHF cross-band setup that someone has in that area, within range of the 145.130 repeater (60-mile coverage area). Someone at AMSAT may want to reach out to the club and enlist their help: http://caara.net/main/ Hope this helps. 73, Dave KM3T

The launch of our Wild Apricot-based member portal on this date retires the dBase database system launched in the early 1980s by then-President Dr. Tom Clark, K3IO (then W3IWI) and is the result of a process authorized by the Board of Directors in 2016. Members now have control over the own profiles. Member communications will be handled via email, resulting in significant cost reduction. Wild Apricot will not only serve AMSAT as our member management plat- form. Other capabilities will be released in the future such as event management, communications, and access to member-only content. Stay tuned for new capabilities being launched over the coming months. As this is a totally new system for AMSAT, we may face challenges ahead. I ask for your patience as the User Services team works through these challenges to provide our members the best user experience poss- ible. Ultimately, Wild Apricot is the right solution moving AMSAT for- ward both technologically and operationally. This effort would not have been possible without the hard work and leadership of Robert Bankston, KE4AL, in his position as Vice Pres- ident of User Services at AMSAT. Significant hours were put into this project. I applaud and congratulate Robert for a successful launch. 73, Clayton W5PFG AMSAT President [ANS thanks Clayton Coleman, W5PFG, AMSAT President, for the above information] -------------------------------------------------------------------- Call for Nominations - 2020 AMSAT Board of Directors Election AMSAT solicits nominations for the 2020 AMSAT Board of Directors election, to be held in the third quarter of the year. The seats of the following three incumbent Directors expire in 2020 and will be filled by this year's election: Tom Clark, K3IO; Mark Hammond, N8MH; and Bruce Paige, KK5DO. Further, up to two Alternate Directors may be elected for one-year terms. A valid nomination for Director must be written and requires either one Member Society or five current individual members in good standing to nominate an AMSAT member. Written nominations, with the nominee’s name, call sign, and contact information, as well as the nominators' names, call signs, and contact information, should be sent to the AMSAT Secretary: Brennan Price, N4QX 300 Locust St SE, Unit E Vienna VA 22180-4869 brennanprice(a)verizon.net A copy should be sent to AMSAT Manager, Martha Saragovitz, at martha(a)amsat.org. The AMSAT bylaws require that the nomination be written and in the form specified by the Secretary. In light of the ongoing pandemic and the resulting closure of the physical office, the Secretary has elected to accept written nomination materials in electronic form, including e-mail or electronic image of a paper document. Fax trans- missions cannot be accepted due to the closure of the office. No matter what means are used, petitions MUST be received by the Secretary no later than June 15th. The Secretary will verify the qual- ifications of candidates and nominating members or Member Societies as petitions are received, and will notify candidates whether their nom- inations are in order by the end of June. [ANS thanks Brennan Price, N4QX, AMSAT Secretary, for the above information] -------------------------------------------------------------------- RS-44 Transponder Now Active The amateur satellite world was surprised to wake up to the news on April 30th that a new transponder was activated for testing and open for use by amateurs worldwide Constructed by specialists at Information Satellite Systems and Students at Siberian State Aerospace University, DOSAAF-85 was launched on a Rockot/Breeze-KM launch vehicle from Plesetsk Cosmo- drome on December 26, 2019. The satellite apparently failed to separate from the upper stage of the launch vehicle and remains attached. The satellite’s name commemorates the 85th anniversary of the Voluntary Society for the Assistance to the Army, Aviation, and Navy (DOSAAF), the organization responsible for the military training of Soviet youth. Designated RS-44, or Radio Sputnik 44, the satellite carries a 60 kHz wide V/u linear transponder and a CW beacon. With an orbit of 1511 km x 1175 km and an inclination of 82.5 degrees, this is the highest orbiting functioning amateur satellite available worldwide. Due to the 1511 km apogee, regular DX contacts should be easy to make. The first claimed DX record came from Joe Werth, KE9AJ, and Jérôme LeCuyer, F4DXV, who reported a 6,993 km trans-Atlantic QSO between EN50gn09 in Illinois and JN04iu40 in France. This was quickly eclipsed less than 24 hours later when Casey Tucker, KI7UNJ, and Tetsurou Satou, JA0CAW, reported the first trans-Pacific QSO between CN93jw (Oregon, USA) and PM97nw (Niigata, Japan), a distance of 7,859 km. The theoretical max- imum range for QSOs via RS-44 is 7,942 km. The NORAD ID is 44909, object 2019-096E. Initial reports from the first days of operation suggest that the transponder is very sensitive and easily workable with low power and handheld antennas, however significant periodic fading is reported, likely due to the fact that the satellite remains attached to the upper stage of the launch vehicle and is unable to deploy its gravity gradient boom to stablize itself. The satellite is planned to remain continuously available for testing purposes until May 11th at which time a decision on further operations will be made. The Keplerian elements for RS-44 have been added to the AMSAT and CelesTrak distributions, as well as several popular tracking apps. The ARRL has released version 11.10 of the TQSL configuration file to add support for RS-44 to LoTW. RS-44 – V/u Inverting Analog SSB/CW Uplink (LSB) 145.935 MHz through 145.995 MHz Downlink (USB) 435.610 MHz through 435.670 MHz CW Beacon 435.605 MHz [ANS thanks Dmitry Pashkov, R4UAB, Igor Blinov, RW3XL, Nico Janssen, PA0DLO, the ARRL, and others for the above information] -------------------------------------------------------------------- Virginia Tech Camera on AO-92 Takes Stunning Photos, Additional Passes Planned Tuesday, May 5th The Virginia Tech camera on board AO-92 was activated on two passes over North America on Tuesday, April 28th. Several great photos were taken, captured by amateur stations running FoxTelem, and uploaded to the AMSAT Central Scrutinizer. All of the photos taken by AO-92 can be viewed on the AMSAT website at the link below. The Virginia Tech camera will be activated again on Tuesday, May 5th during morning passes over the United States. The camera remains active for 45 minutes after being enabled by a ground station. Stations in the United States, the Caribbean, Mexico, Central, and South America are encouraged to set their stations up to receive and upload high speed telemetry in FoxTelem. FoxTelem downloads and instructions can be found at https://www.g0kla.com/foxtelem/index.php AO-92 Camera Image Archive: https://www.amsat.org/tlm/showImages.php?id=4 [ANS thanks Drew Glasbrenner, KO4MA, AMSAT Vice President - Operations for the above information] -------------------------------------------------------------------- Redesigned AMSAT CubeSat Simulator Launched A new design for the CubeSatSim, the AMSAT CubeSat Simulator is now available on GitHub (http://cubesatsim.org/code). The CubeSatSim is a Raspberry Pi Zero W-based functional model of a “1U” CubeSat nano- satellite for demonstrations and educational outreach. It has a 3D- printed frame structure and is designed to act, as reasonably as poss- ible, as one flying in Low Earth Orbit (LEO). The simulator runs on rechargeable battery power and solar panels and transmits its authentic voltage, current, and temperature telemetry on the UHF Amateur Radio band. The CubeSatSim has been presented at the AMSAT Space Symposium the past two years and at Hamvention last year. The new design was developed to reduce the cost to build and to im- prove functionality. Jim McLaughlin, KI6ZUM, and David White, WD6DRI, are prominent STEM advocates and school mentors in the San Diego area. They offered to help redesign the hardware and collaborated with Alan Johnston, KU2Y, AMSAT VP Educational Relations, and Pat Kilroy, N8PK, over the past nine months. The resulting design has reduced the cost to build in half (from around $400 to around $200) and added a new Fox-1 emulation mode. In addition to the AFSK (Audio Frequency Shift Keying) and 1200 bps APRS (Automatic Packet Reporting System) telemetry in AO-7 format of the original design, the new version supports DUV (Data Under Voice) FSK (Frequency Shift Keying) 200 bps telemetry com- patible with Fox-1A through Fox-1D and BPSK (Binary Phase Shift Keying) 1200 bps telemetry compatible with HuskySat-1 and the upcoming Fox-1E. Chris Thompson, G0KLA/AC2CZ, the author of AMSAT’s FoxTelem satellite telemetry software, has put out a testing version 1.09 of the software that supports the CubeSatSim. Instructions on how to download and con- figure this test version are on the GitHub Wiki. http://cubesatsim.org/wiki Also new to the CubeSatSim is a STEM Payload board with a STM32F103C8T6 “Blue Pill” Arduino compatible microcontroller. The board also has a built-in BME-280 Temperature Humidity Barometric Pressure Sensor and an MPU-6050 (GY-521) 3-Axis Accelerometer and Gyro. Also new is a tape measure dipole or monopole or SMA antenna, an integrated Band Pass filter, and a sturdy new 3D printed frame and more powerful solar panels. A new Twitter account @CubeSatSim has also been launched. Follow to get the latest updates on the CubeSatSim including videos and photos. Links to all CubeSatSim resources are at CubeSatSim.org. More details on the redesigned CubeSatSim can be found in the March/ April 2020 edition of The AMSAT Journal, available at https://tinyurl.com/ANS-MarAprJournal The CubeSatSim team wishes to thank the AMSAT board, President, and all AMSAT members for their ongoing support of this educational project.

The following satellite has been activated and added to this week's AMSAT TLE Distribution: RS-44 - NORAD Cat ID 44909. Per Nico Janssen, PA0DLO concerning RS-44: "The new amateur payload DOSAAF 85 (RS-44) appears to work very well. Doppler measurements confirm that it is indeed object 44909, 2019-096E. The satellite identifies itself as "RS44" (i.e. Radio Sputnik 44) on its CW beacon on 435.6043 kHz. The passband is about 63 kHz wide. It may also have a downlink between 2400 and 2485 MHz. The frequencies of RS44/DOSAAF 85 have not been IARU coordinated. The satellite is in an elliptical orbit with a perigee of 1175 km, an apogee of 1511 km and an inclination of 82.5 degrees. The payload is apparently attached to the Breeze-KM upper stage of a Rokot launch vehicle that launched three Gonets satellites on December 26, 2019. It was originally expected to launch in 2015. It is based on the Yubileiniy platform."

The newly adopted regulations increase the disclosure re- quirements for pre-space notifications submitted for amateur space stations. In the draft version of the R&O, released in early April, the FCC had included the adoption of additional requirements regarding indemni- fication and maneuverability. AMSAT, ARRL, university researchers, and satellite industry groups opposed certain aspects of these rules. In response, the Commission moved those provisions to a FNPRM for further comment. In addition to maneuverability and indemnification requirements for amateur space stations, the Commission also seeks comment on a disposal bond requirement for certain spacecraft. AMSAT is evaluating the FNPRM and will file comments expressing our views of the proposed regula- tions.

During the global Space Apps COVID-19 Challenge, participants from a- round the world will create virtual teams that - during a 48-hour per- iod - will use Earth observation data to propose solutions to COVID- 19-related challenges ranging from studying the coronavirus that causes COVID-19 and its spread to the impact the disease is having on the Earth system. Registration for this challenge opens in mid-May. "There's a tremendous need for our collective ingenuity right now," said Thomas Zurbuchen, associate administrator for NASA's Science Mis- sion Directorate. "I can?t imagine a more worthy focus than COVID-19 on which to direct the energy and enthusiasm from around the world with the Space Apps Challenge that always generates such amazing solutions." The unique capabilities of NASA and its partner space agencies in the areas of science and technology enable them to lend a hand during this global crisis. Since the start of the global outbreak, Earth science specialists from each agency have been exploring ways to use unique Earth observation data to aid understanding of the interplay of the Earth system -- on global to local scales -- with aspects of the COVID- 19 outbreak, including, potentially, our ability to combat it. The hackathon will also examine the human and economic response to the vi- rus. ESA will contribute data from the Sentinel missions (Sentinel-1, Sent- inel-2 and Sentinel-5P) in the context of the European Copernicus pro- gram, led by the European Commission, along with data from Third Party contributing Missions, with a focus on assessing the impact on climate change and greenhouse gases, as well as impacts on the economic sector. ESA also is contributing Earth observation experts for the selection of the competition winners and the artificial-intelligence-powered EuroDataCube. "EuroDatacube will enable the best ideas to be scaled up to a global level," said Josef Aschbacher, director of Earth Observation Programm- es at ESA. "The pandemic crisis has a worldwide impact, therefore in- ternational cooperation and sharing of data and expertise with partners like NASA and JAXA seems the most suitable approach." JAXA is making Earth observing data available from its satellite mis- sions, including ALOS-2, GOSAT, GOSAT-2, GCOM-C, GCOM-W, and GPM/DPR. "JAXA welcomes the opportunity to be part of the hackathon," said JAXA Vice President Terada Koji. "I believe the trilateral cooperation among ESA, NASA and JAXA is important to demonstrate how Earth observation can support global efforts in combating this unprecedented challenge." Space Apps is an international hackathon that takes place in cities around the world. Since 2012, teams have engaged with NASA's free and open data to address real-world problems on Earth and in space. The COVID-19 Challenge will be the program's first global virtual hacka- thon. Space Apps 2019 included more than 29,000 participants at 225 events in 71 countries, developing more than 2,000 hackathon solutions over the course of one weekend. Space Apps is a NASA-led initiative organized in collaboration with Booz Allen Hamilton, Mindgrub, and SecondMuse. The next annual Space Apps Challenge is scheduled for October 2-4.

During the last several weeks, efforts to contain the spread of the COVID-19 virus have resulted in massive school closures worldwide. In addition, the Stay-At-Home policies invoked by authorities, initially shut down opportunities for ARISS school contacts for the near future. To circumvent these challenges and keep students and the public safe, ARISS is introducing the Multipoint Telebridge Contact via Amateur Radio concept. First operation of this experimental system occurred during a contact with a group of Northern Virginia Students located in Woodbridge, VA on Thursday, April 30 at 13:35 UTC (9:35EDT). During this event, an ARISS telebridge radio ground station linked to the astronaut on the International Space Station (ISS)ham radio station and each Stay-At-Home student and their teacher was individually linked to the telebridge station. Under the teacher’s direction, each student, from their home, takes a turna sking their question of the astronaut. Quoting ARISS Chair Frank Bauer, “This approach is a huge pivot for ARISS, but we feel it is a great strategic move for ARISS. In these times of isolation due to the virus, these ARISS connections provide a fantastic psychological boost to students, families, educators and the public. And they continue our long-standing efforts to inspire, engage and educate students in STEAM subjects and encourage them to pursue STEAM careers.” An archive of the April 30th contact can be viewed at https://youtu.be/Cu8I9ose4Vo. 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 Corp- oration (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.

Above-constellation use of GPS was first demonstrated on AMSAT-OSCAR 40. AMSAT Vice President - Human Space- flight Frank Bauer, KA3HDO, is extensively quoted in this article. Read it at https://aerospaceamerica.aiaa.org/features/cosmic-gps/ + AMSAT's Zazzle store has added a few new products, including a water bottle, car flag, and fanny pack. A wide variety of other products are also available, including the popular new OSCAR t-shirt. Check out the store at https://www.zazzle.com/store/amsat_gear. 25% of the purchase price of each product goes to AMSAT to help Keep Amateur Radio in Space. + Scientists from NASA, the United States Geological Survey (USGS) and the Lunar Planetary Institute have created a detailed new map of the lunar surface in stunning color. Called the Unified Geological Map of the Moon, it marries decades of surveys of the moon’s surface going as far back as Armstrong and Aldrin’s Apollo mission, with more re- cent data from NASA and JAXA. It doesn’t just look pretty — the map will greatly help NASA and other organizations plan future landing sites optimized for scientific missions. NASA's Artemis project could take humans to the moon as early as 2024. AMSAT, along with ARISS, partners, is developing an amateur radio package, including two-way communication capability, to be carried on-board Gateway in lunar or- bit as part of an Artemis precursor initiative. The digital map is available for the public at: https://on.doi.gov/2YnZGAO + Scott Chapman, K4KDR, is featured in Scott Manley's new video about the Iranian Noor satellite. https://youtu.be/SPTz7Ig9RQE + As another part of the RSGB "Get on the air to care" campaign, the May edition of RadCom is being made available to radio amateurs around the world to read online as a sample edition. A number of IARU national societies have taken a similar step and the RSGB is happy to join those societies in supporting the worldwide amateur radio community during these difficult times: https://www.rsgb.org/sampleradcom + In a Public Notice released on April 30th, the FCC confirmed that amateur license examinations may be conducted remotely.

AMSAT Field Day 2020
by Bruce 02 May '20

02 May '20

I have been monitoring the ARRL to see what they will be doing or changing for field day. Unfortunately my field day article did not make it into this issue (April/May) of the journal. The ARRL has on their website this for right now... "With 2020 ARRL Field Day – one of the biggest events on the Amateur Radio calendar – just about 12 weeks away, ARRL officials are monitoring this situation with the coronavirus very closely and paying close attention to all of the information and guidance being offered by the CDC's Centers for Disease Control and Prevention (https://www.cdc.gov/coronavirus/2019-ncov/index.html)." For right now, we will play it by ear and make adjustments to field day as it gets a bit closer. Hopefully more restrictions are lifted and we can plan radio a little bit more like normal. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

Struggling with IC-9700 and WSJT-X
by Richard Lawn 02 May '20

02 May '20

Recently my Windows 10 computer went through an upgrade and ever since then I cannot get WSJT-X to talk via CAT to my 9700. I've tried the obvious things like unplugigng the USB cable and plugging it back in again and no dice. I even reinstalled WSJT-X because I found that HRD was working just fine. I'm at a loss on this. Any suggestions out there? Rick, W2JAZ

Ah! The response from the guy who built the software. Thanks very much Eric. Interestingly, the PDF of the user manual will not display the opcode chart. Just shows the heading and the rest of the page is blank. O well. Tom Schuessler, N5HYP Message: 7 Date: Sat, 2 May 2020 10:04:08 +0200 From: Erich Eichmann <mailto:[email protected]> To: mailto:[email protected] Subject: Re: [amsat-bb] po-101 sub tone Message-ID: <mailto:[email protected]> Content-Type: text/plain; charset=utf-8; format=flowed Hi, as far as I see the code for the FT-847 for a 141.3 sub tone is hex 08 (p. 93 of the user manual) , for the TS-2000 it is dec. 22. Therefore the entry in SubTone.SQF for a 141.3 sub tone for Icom radios, Yaesu FT-847 and Kenwood TS-2000 should be: PO-101,141.3,$08,22 73s, Erich, DK1TB

Still Waiting......
by Gerald Witalec 02 May '20

02 May '20

Approximately two weeks ago, I ordered the book written by Steve Ford, WB8IMY, "Amateur Radio Satellites for Beginners" so as to complimentmy library of books on Ham Radio. USPS has terribly failed to deliver my book and their posting is not updated daily. Last update I received on their web site was April 27th and now, this morning it is May 2nd with NO updates. I noticed that USPS delivery trucks making deliveries with evenlarger packages then the book. I have no idea when I will receive it. Looks like I will wait another week and then just cancel my order. It took me over two weeks to receive an antenna from HRO Milwaukee. I was thinking about purchasing the IC-9700 for the SATS and 2M/70 cm repeaters. Now I have my doubts as to when I would ever receive it and in what condition it may be in when delivered. I was thinking about driving to Milwaukee to it curb side during this virus crisis, but that is a seven hour one way drive from my QTH. No wonder the wife keeps asking when will I give up the hobby.Totally frustrated...Jerry.....W8RQM
