Quansheng UV-K5/K6 on satellites
by JOHN GEIGER 18 Aug '24

18 Aug '24

Has anyone used the Quansheng UV-K5 or k6 (or other variants) on the satellites yet, especially the linear satellites? I see that there are now firmware mods to these HTs that not only allow for SSB reception-but also SSB transmission on 2m and 70cm. It is actually Double Side Band supressed carrier but several Youtube videos show it working well on 2m USB. So, since the satellites conventionally use LSB for the uplink, wouldn't the DSB transmit audio also provide a LSB signal that would be inverted to USB by the satellite? I wouldn't expect stellar performance out of these HTs but I do think a pair of them could make a budget friendly portable SSB station for some grid activations. Using them would be better than being QRT while in that grid because you couldn't afford a pair of FT817s or IC705s 73 John AF5CC Sent using {0}

What happened to Greencube IO-117?
by Rajesh Vagadia - VU2EXP 18 Aug '24

18 Aug '24

Dear all, Few months back I was trying to work Greencube Satellite with my limited setup, I was able to receive signal packets & telemetry with my 7 ele uhf Arrow antenna, though I could never Transmit & successfully trigger this Bird, perhaps my IC-705 limited 10W power was the issue. Now I am equipped with a new High gain cross yagi (14ele) to test & try Greencube! I observed since more than a week Greencube is not QRV! Can anyone give idea what happened to this beautiful bird? I am quite eager to work via this satellite from my grid ML52JH. I would also like to get response/guidance from user with Icom IC-705 who worked this bird successfully. Thank you in advance. 73 Rajesh P. Vagadia VU2EXP Rajkot - Gujarat India Regional Coordinator •AMSAT-INDIA •Amateur Radio Society of India

(***) 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.

Does anyone know the size of the setscrew in the NJC-207-PF 7-pin rotor cable connector housing used for the Yaesu G5500? The NJC data sheets & drawings I found do not include this information, and my thread gauges don't go small enough. I'm assuming a metric thread. Thanks! 73 Steve KS1G

The voting period will conclude on September 15th and results will be announced no later than September 30th. *[ANS thanks Jeff Davis, KE9V, AMSAT Secretary for the above information]* ------------------------------ AMSAT Mail Alias Service to End August 31, 2024 A long-standing member service, the AMSAT Mail Alias Service is scheduled to end on August 31, 2024. A mail alias on AMSAT.ORG permitted people to send an email to members without knowing their actual internet email address. They just needed to know their amateur radio callsign. Unfortunately, the unchecked rise in domain name hacking and email account high-jacking has made it impossible to sustain this service at a cost-effective level. The number of callsign(a)amsat.org email accounts that had been hijacked and converted to zombie spam accounts over the years had led many internet service providers and gateway centers to ban all @ amsat.org email addresses, including those business accounts of AMSAT officers and officials. The tireless efforts of AMSAT’s all volunteer IT staff has worked for years to repair much of the damage, but AMSAT still get complaints from members who are not getting their personal emails, ANS bulletins or AMSAT-BB posts because of persistent delivery problems. It has come to the point where the AMSAT volunteer IT staff can no longer keep up with the maintenance requirements to keep the alias mail list clean and to work with email gateways to remove blocks. And, after considerable investigation into alternative paid email services, AMSAT leadership decided that the money required to keep an email alias system alive would be better spent on building and flying satellites for its members. Persons using the Mail Alias Service should begin to migrate to different email accounts so they do not lose receipt of personal emails, AMSAT News Service Weekly Bulletins, AMSAT-BB posts, or official messages from AMSAT itself. Members are especially asked to make sure they are NOT using a callsign(a)amsat.org as their registered email address in the AMSAT membership portal. Members can easily change their registered member email address by logging into the portal and updating their profile. *[ANS thanks the AMSAT IT Team for the above information]* ------------------------------ *The 2024 Coins Are Here Now!Help Support GOLF and Fox Plus.**Join <https://www.amsat.org/join-the-amsat-presidents-club/> the AMSAT President’s Club today!* ------------------------------ Changes to AMSAT TLE Distribution for August 16, 2024 Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched.

Philippe, EA4NF will be QRV (*as KE4NF*) from *EL94* 13-17 Aug, then *EL95* 25-27 Aug. Looks like this will be FM LEO only. *Log as KE4NF.* In between these two activations, Philippe will activate Grenada (FK92) as J38NF on FM satellites, August 18-23. *Log as J38NF.* *[ANS thanks Ian Parsons, K5ZM, AMSAT Rover Page Manager, for the above information]* ------------------------------ * Want to fly the colors on your own grid expedition?* Get an AMSAT car flag and other neat stuff from our Zazzle store <https://www.zazzle.com/store/amsat_gear>! 25% of the purchase price of each product goes towards Keeping Amateur Radio in Space ------------------------------ AMSAT Ambassador Activities AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events. AMSAT Ambassador Clint Bradford, K6LCS, says, "Think a 75-minute presentation on "working the easy satellites" would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!"

Shanghai Spacecom Satellite Technology (SSST)’s new constellation, translated as "Thousand Sails," may grow to as many as 14,000 satellites. It joins potentially two other under-development broadband Chinese megaconstellations, each proposing over 10,000 satellites, in competition with OneWeb, Kupier, and Starlink. Unfortunately, the LM-6A’s upper stage appears to have malfunctioned and scattered over 700 pieces of space debris in a fairly high 800 km orbit (again). The debris at this altitude will likely take about a century for orbital decay. (ANS thanks The Orbital Index for the above information) + Orbital Space has announced its Lunar Program to send a student-built experiment to the Moon, marking the Arab world’s first privately funded lunar mission. The experiment by students from AGH University of Science and Technology in Poland focuses on analyzing interactions between lunar regolith and various materials that could be used in making cables and connectors for future lunar missions. Astrobotic will carry the payload on its third lunar mission aboard a Griffin-class lunar lander, targeting launch no earlier than Q4 2026. (ANS thanks Spacewatch Global for the above information) + The 2024 Olympic Games officially began in Paris, France on July 26, with athletes coming from around the world to compete. Meanwhile, above the world — on our orbiting laboratory, the International Space Station — NASA's astronauts got into the Olympic spirit. Check out their training montage from space, followed by a message to Earth from astronaut Matt Dominick at https://www.youtube.com/watch?v=ycDoaIn6wuk (ANS thanks The Orbital Index and NASA for the above information) + From Dave, G4DPZ, regarding the FUNcube Data Warehouse: "Our hosting provider has told us that they will be migrating our services to a new virtual machine on the 1st of September. Unfortunately the versions of the MySQL database server and Java runtime available on the new instance are not compatible with the current application implementation. Therefore I have to rebuild the development tool chain and migrate the application to suit the new instance. The work is underway but may take us into early September. We do know that database table migration works as we have already done a test of migrating the several GB of database between machines. If we do have any outage, the dashboards will upload when they detect the new instance is alive." (ANS thanks Dave Johnson, G4DPZ, Hon. Sec., AMSAT-UK, for the above information) + The SpaceX Transporter-11 rideshare mission launched 116 payloads from Vandenberg Space Force Base in California on August 16th. Four of these payloads carry transmitters on amateur bands. NIGHTJAR and TORO carry amateur UHF transmitters, but are not IARU coordinated. QUBE carries an amateur UHF transmitter, but its IARU coordination was declined. ORESAT0.5 is the sole IARU coordinated amateur mission on this launch with downlinks of 436.500 MHz and 2422.0 MHz. More information about ORESAT can be found at https://www.oresat.org/satellites/oresat0-5. Discussion regarding this launch can be found on the LibreSpace forum at https://community.libre.space/t/spacex-f9-transporter-11-rideshare-vsfb-slc… (ANS thanks LibreSpace and the ORESAT team for the above information) + Three AMSAT GridMaster Awards were awarded over the past week: #67 was awarded to Endaf, N6UTC, #68 was awarded to Raymond, KN2K, and #69 was awarded to Steven, KC1MMC. Congratulations to both. Additionally, two Reverse VUCC Awards were issued. #15 was awarded to Sean, KX9X, with 103 grids and #16 was issued to Randy, ND0C, with 109 grids. Congratulations to all the new award recipients! More information about AMSAT's awards program can be found at https://www.amsat.org/awards-2/ (ANS thanks Bruce Paige, KK5DO, AMSAT Director of Contests and Awards for the above information) + IO-117's digipeater has not been operational for the past week. No further information is available regarding its status or expected timeframe for a potential return to service. + AMSAT's Operations team, in coordination with the University of Maine and AMSAT Engineering, continues to work to complete MESAT1's science mission. More telemetry coverage is needed! If you have UHF receive capability, please download FoxTelem <https://www.amsat.org/tlm/> and help us capture more data.

Hi Chris, thanks for getting back to me. Both Mark and JoAnne replied off-list. I have re-entered the correct freq and will be testing this evening. 73, John Antonuk AL7ID(a)yahoo.com On Saturday, August 17, 2024 at 10:45:09 AM AKDT, Chris Thompson via AMSAT-BB <amsat-bb(a)amsat.org> wrote: John, 435.800 is the center frequency.

There is some trial and error here as your radio calibration might vary vs someone else's. 73Chris On Sat, Aug 17, 2024, 13:48 John Antonuk - AL7ID via AMSAT-BB <amsat-bb(a)amsat.org> wrote: Hi, I'm not sure how this happened but my SAT controller memory for MESAT-1 telemetry got set to 435.909 What frequency are folks using?

John, 435.800 is the center frequency. You want that to be 1200 Hz or more above your carrier frequency if you are using USB.

Hi, I'm not sure how this happened but my SAT controller memory for MESAT-1 telemetry got set to 435.909 What frequency are folks using? SatNOGS says 435.800 but seem to recall it was actually a bit lower.... 73, John Antonuk AL7ID(a)yahoo.com
