by Patrick STODDARD (WD9EWK/VA7EWK) 16 Feb '20

16 Feb '20

Hi! On my way home Sunday (16 February), I will make a stop on the DM22/DM32 grid boundary about 25 miles/40km east of Yuma, Arizona, near the I-8 freeway. I will work the AO-92 and AO-91 passes that come by starting around 1700 UTC, and may be able to try the XW-2A passes before then. I don't know how long I can stay out there to work other passes, but I will post updates on my @WD9EWK Twitter account. If you do not use Twitter, you can view my tweets in a web browser at: http://twitter.com/WD9EWK APRS coverage appears to be working east of Yuma, and I hope to show up as WD9EWK-9 once I leave the Yuma area: http://aprs.fi/WD9EWK-9 I will upload QSOs made on the DM22/DM32 line to Logbook of the World when I return home. If anyone would like a QSL card for a contact, please e-mail me the QSO details. No need to first send me a card or an SASE, before I send out a card. Thanks, and 73!

Having not been heard throughout the most recent period of full illumination, it is reasonable to believe the batteries have deteriorated to the point of no longer being able to power the trans- mitter. Should some future event cause a cell to open, it is possible the satellite may be heard again, but for now it is time to declare end-of-mission. AO-85 was conceived as the first AMSAT cubesat, and was designed to be a successor to the popular AO-51 microsat. Accepted into the NASA CubeSat Launch Initative in February 2012, AO-85 was launched October 8, 2015. AO-85's success led to further Fox satellites AO-91, AO-92, AO-95, and RadFxSat2 / Fox-1E which will be launched later this year. The Fox-1E transponder was also spun off into a radio system now in orbitonboard HuskySat-1, and soon to be in several other university cubesats. Development continues on GOLF-TEE and GOLF-1, which will include a legacy V/u linear transponder and a SDR-based multiband uplink and 10 GHz downlink radio system. Your continued support of AMSAT by member- ship and donations will help us Keep Amateur Radio in Space.

Health data includes temperatures, battery charge state, and solar panel charging. • Over the weekend, the camera payload took and transmitted the first pictures from space! The camera included collaboration with Raisbeck Aviation High School and nonprofit Quick2Space. Commissioning of the satellite systems is still underway. The sat- ellite has actually been in space inside a Nanoracks deployer since launch on Nov 2nd. The main research goal of satellite is to demon- strate the new propulsion and communication technologies on the sat- ellite. At the completion of the research phase, the satellite will be utilized as an amateur transponder. The mission of the UW program, housed in the Department of Earth and Space Sciences, is to foster interdisciplinary student participation in space systems research, to inspire and train future space scien- tists and engineers, and to advance spacecraft capabilities at the University of Washington. On February 15th, AMSAT Vice President - Engineering Jerry Buxton, N0JY, hosted a Twitch stream to discuss the AMSAT Linear Transponder Module (LTM-1) and HuskySat-1. You can see a replay of the livestream at https://www.twitch.tv/videos/552209241 [ANS thanks Paige Northway of the HuskySat-1 team and Jerry Buxton, N0JY, AMSAT Vice President - Engineering, for the above information] -------------------------------------------------------------------- Update from AMSAT President Clayton Coleman, W5PFG I am humbled by the greetings and congratulatory messages received over the past ten days since becoming the President of AMSAT. Please join me in expressing gratitude to our immediate past president Joe Spier, K6WAO, for his dedication to AMSAT’s mission of Keeping Amateur Radio in Space. It was a pleasure to speak with many of our members at the Orlando Hamcation last weekend. Attending Hamcation afforded me the opportun- ity to meet with many of our volunteers and reach out to other organi- zations in amateur radio such as the ARRL and the Dayton Amateur Radio Association. My priority, now underway, is to ensure all Directors have equal access to AMSAT resources to perform their duties. AMSAT complies with Section 29-413.05 of the District of Columbia Nonprofit Corporation Act of 2010. Most of the information Directors use to perform their duties are already publicly available on the Internet on our website, published in the AMSAT News Service (ANS), and often in print as part of The AMSAT Journal. These resources are not password protected and can be viewed by members and non-members alike. Once I’ve had an opportunity to speak individually with the Directors, I will convene a Board of Directors teleconference to address out- standing business. At any time, three Directors may call on the Pres- ident to schedule a Board of Directors meeting, per our bylaws Article II, Section 5, Paragraph A. 73, Clayton W5PFG AMSAT President [ANS thanks Clayton Coleman, W5PFG, AMSAT President, for the above information] -------------------------------------------------------------------- Free Digital Copy of "Getting Started with Amateur Satellites" Avail- able for New or Renewing Members While HuskySat-1 completes it's scientific mission, check out the best resource for learning how to work through linear transponder sat- ellites (and other types of amateur satellites).

By the time you read this, HuskySat-1 should be in orbit and completing its science mission before being turned over to AMSAT for amateur radio use. I want to congratulate all those involved with this project both at the University of Washington and on AMSAT’s Engineering and Operations teams who worked to make this mutually beneficial partnership happen. More details about HuskySat-1 and our partnership with the Husky Satellite Lab at the University of Washing- ton can be found elsewhere in the January/February 2020 issue of The AMSAT Journal. While we look forward to the completion of HuskySat-1's primary miss- ion, we also await the launch of the final Fox-1 satellite, RadFxSat-2 / Fox-1E, which is currently scheduled to launch no earlier than the first quarter of this year on the ELaNa XX mission. The ELaNa XX miss- ion will fly on the second flight of Virgin Orbit's LauncherOne ve- hicle. As the Fox project wraps up its series of five 1U CubeSats, progress continues on GOLF, the next generation of AMSAT satellites. A group of GOLF-TEE (Greater Orbit Larger Footprint – Technology Evaluation En- vironment) satellite prototype boards transmitted telemetry for the first time on Tuesday, January 14th. During the test, the boards were laid out on a bench as a "flat-sat" with interconnecting wires, bench power supplies, and a dummy load on the transmitter. The inter- connected boards included: • An early RT-IHU (Radiation Tolerant Internal Housekeeping Unit - i.e., computer) prototype, • A CIU (Control Interface Unit) prototype, and • A set of spare boards from HuskySat-1 that act as prototypes for the LIHU (Legacy IHU) and legacy VHF/UHF RF components. Now that the team has reached this point, AMSAT Engineering has RF to use as a basis for developing a GOLF-TEE decoder for FoxTelem, our ground telemetry receiver software. Thousands of hours of work by many AMSAT volunteers have gone into the hardware and software that got us this far, with much work yet to be done before the assembly of flight units. The GOLF-TEE satellite is designed as a Low Earth Orbit (LEO) testbed for technologies necessary for a successful CubeSat mission to a wide variety of orbits, including MEO (Medium Earth Orbit) and HEO (High Earth Orbit). The work on GOLF is intended for our CubeSat missions to higher orbits. However, much as the Fox-1E linear transponder was adapted as a payload for HuskySat-1, components developed for GOLF, such as the RT-IHU and the microwave SDR transponder, can be adapted to serve as the basis for a hosted payload on a commercial or government sat- ellite in geostationary orbit or perhaps an educational CubeSat des- tined for MEO or GTO. Should an opportunity arise, the work being done on GOLF means that we will be ready to build such a hosted payload. While we continue our work on these satellites, we face the prospect of regulatory roadblocks. Last year, we submitted comments on the Federal Communication Commission's Notice of Proposed Rulemaking re- garding the mitigation of orbital debris. The proposed rules as worded would severely limit the type of missions AMSAT could pursue. While the Commission has not yet issued final rules, we are hopeful that the near-unanimous opposition of commenters to the more harmful as- pects of the rules, such as the requirement for satellite operators to indemnify the United States Government for any potential claims regarding their satellites, will limit the negative impact. Another serious concern is our access to spectrum. While international threats that arose in the months before the 2019 World Radiocommunica- tion Conference to the 144 MHz – 146 MHz and 1260 MHz – 1270 MHz ama- teur satellite service bands have subsided for the time being, other threats appear on the horizon. This past December, the FCC issued a Notice of Proposed Rulemaking that would delete the amateur alloca- tion at 3.3 GHz – 3.5 GHz, including the amateur satellite service allocation at 3.4 GHz – 3.41 GHz. While that band has not yet been used for any amateur satellites as it is not available in ITU Region 3 (Asia & Oceania), it is still a potentially useful resource for a future amateur geostationary payload over the Americas. Additionally, we know that many AMSAT members also use this band for other purposes, such as mesh networking, contesting, and EME commun- ications. Access to microwave spectrum is crucial for many of our planned activities, including GOLF and amateur radio on the Lunar Gateway, and we must vigorously defend our spectrum allocations. AMSAT is currently drafting comments opposing this proposed rule, and, working alongside the ARRL, we continue to monitor potential legis- lative and regulatory actions that could limit or even preclude some of our current and planned activities. On a final note, I wanted to let the membership know that AMSAT's ser- vers will be migrating to a new operating system and a new hosting service later this year. This is necessary as the operating system currently running AMSAT's servers will reach its end of life in Nov- ember. While AMSAT's capable IT team led by Joe Fitzgerald, KM1P, will do their best to minimize any disruptions to AMSAT services, this type of transition can often result in unforeseen problems.

IC-9700 drift solution
by D. Craig Fox 15 Feb '20

15 Feb '20

I hope this doesn’t violate BB protocol, but given the interest in adding freq stability to the 9700, I thought this post from the moon-net might be of interest (and I don’t even own a 9700). I expect PA2V can be found on QRZ 73, Craig N6RSX Hi all, As earlier announced on here I installed a 49.152 MHz oscillator (PLL) that will lock on 10 MHz into my IC9700. I have tested it for a week now and compared it to my K3 with transverter. My K3 and transverter are locked on 10 MHz too. During the whole week there was no difference in frequency between both setups. The drift problem on the ICOM IC9700 is solved! It is a simple job without really changing the rig hardware. The PLL can be installed into the 9700 but if one want it outside, it is possible too. You need a 10 MHz reference for this mod. I have made a description but it is a bit too big to post it on here. The file with pictures is 4 MB and available in Dutch and English. It describes the items you need and how to install and setup the rig. Also it refer to the hams and organisations who did a major job on this too. Total investment for this mod will be around €90 depending on shipments costs and eventually import tax. Hopefully ICOM will finally install this simple solution in future models. After all it is just a solution for a big mistake from their engineers. 73, Peter PA2V

Re: [amsat-bb] Leo Bodnar ICOM IC-9700 Reference Injection Board
by Bob Hammond 15 Feb '20

15 Feb '20

Mark, thanks for your description. I followed it but could not see my 2M "birdy" move at all when enabling/disabling the reference board output! I would like to assume that my 9700 is just so stable that the reference board is making little difference. I did hear a very slight beat frequency change when I enabled/disabled the reference board output. What I did was adjust the coarse and fine sliders in the Ref section of the radio until the beat frequency was zero WITH the GPSDO output on. I could hear a slight beat frequency when I shut it off. Think that's a valid test? I have yet to repeat all this at 23cm. I was expecting a whopper correction using the GPSDO. 73, Bob W7OTJ On Fri, Feb 14, 2020 at 6:38 AM Mark L.

FUNcube Warehouse Outages
by David Johnson 15 Feb '20

15 Feb '20

Hi, There may be some short outages in the operation of the warehouse today as I make some changes to the reporting. The dashboards will resume uploads each time the warehouse comes back online. Realtime min-max values may look a bit strange until I've stabilised the service later today. Thank you all for supporting the project 73 Dave, G4DPZ

Newbie Questions - ISS
by ka3hdo＠gmail.com 15 Feb '20

15 Feb '20

There is a great deal of information on the ARISS web site www.ariss.org <http://www.ariss.org> . News of note is usually posted on the main page. This includes the fact that our first (of two) next generation radio systems is getting ready for launch on SpaceX-20 (tentative launch date--March 2). Look under the news tab for upcoming school contacts (with a 145.80 downlink). Weekly reports provide a view of what is happening in the ARISS community. General Contacts Tab provides info on working the ISS (Primarily APRS and SSTV downlinks). Joanne's APRS resource guide is linked on this page. The link to the SSTV galley can also be linked from this site. Enjoy! 73, Frank KA3HDO Message: 12 Date: Fri, 14 Feb 2020 10:11:45 -0500 From: Jackie Dander <shorenicehere(a)gmail.com <mailto:[email protected]> > To: amsat-bb(a)amsat.org <mailto:[email protected]> Subject: [amsat-bb] Newbie Questions - ISS Message-ID: <CAHHZQ2mqxdGdy3woKwaHGXgwjha8ZUMO=wMv7ta2q_WqOfi_cA(a)mail.gmail.com <mailto:CAHHZQ2mqxdGdy3woKwaHGXgwjha8ZUMO=wMv7ta2q_WqOfi_cA@mail.gmail.com> > Content-Type: text/plain; charset="UTF-8" 1. Is this the best way or place to post such questions? 2. I have studied past posts and other sources but can't find answers to questions below. 3. I am trying to listen to ISS. N2Y0 and HeavensAbove list the same pass for my location today (FM14be, 16:39 local time, elevation 56 degrees) but AMSAT predictor says 4 degrees for that pass. Why the difference? 4. N2Y0 says up/down is 437.550/437.550, ASFK, inactive. HeavensAbove says 145.825/447.550 FM active. Who is right? How can I get correct frequencies to listen to? thanks Isaac -------------------------------------------- Frank H.
