ARISS News Release No.23-04 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org FORIMMEDIATE RELEASE ARISSContact is Scheduled with Students at Cache County School District, Millville, Utah,USA February5, 2023—Amateur Radio on the International Space Station (ARISS) has receivedschedule confirmation for an ARISS radio contact between an astronaut aboardthe International Space Station (ISS) and students at RidgelineHigh School located in Millville, UT. ARISS conducts 60-80 of these special amateurradio contacts each year between students around the globe and crew memberswith ham radio licenses aboard the ISS. Cache County School District (District) is sponsoring this ARISScontact, which will take place at Ridgeline H.S. in the suburban community ofMillville, UT. The District offers 12-week-long astronomy courses; about 150 astronomystudents in grades 9-12 (ages 14-18 years) from both Ridgeline HS and nearby SkyView HS will be at Ridgeline HS for the contact. The District’s mainorganizational partner for this contact is the Bridgerland Amateur Radio Club(BARC), club call sign W7IVM. Members of BARC have provided technical expertisefor the radio equipment setup and will be operating the ground station duringthe contact. Students have also been learning about amateur radio from BARCmembers during Ham radio license classes, and participating in hands-onactivities during the club’s HF field contests and other ham classes. BARCmembers also provided Ham radio exam sessions for the students and thecommunity. Other activities BARC members provided the astronomy students includedparticipation in amateur radio satellite contacts, and a hidden transmitterhunt. This will be a direct contact via Amateur Radio allowing students to ask their questions ofAstronaut Josh Cassada, amateur radio call sign KI5CRH. The downlink frequencyfor this contact is 145.800 MHZ and may be heard by listeners that are withinthe ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contactis in Millville, UT, USA. Amateur radio operators using call sign W7IVM, willoperate the ground station to establish and maintain the ISS connection. TheARISS radio contact is scheduled for February 7, 2023 at 11:45:54 am MST(Utah) (18:45:54UTC,1:45 pm EST, 12:45 pm CST, 10:45 am PST). The public is invitedto watch the live stream at: Astronomy students prepare to talklive with an astronaut on the International Space Station or at The PodCACHE: Making Contact withthe International Space Station _______________________________ Astime allows, students will ask these questions: 1.What is your biggest, personal goal in relation to space? 2.What keeps you pushing your limits when you are struggling to find motivation? 3.Was there a specific book, movie, or show that inspired you to become anastronaut? 4.How excited do you feel about the Artemis program and its upcoming missions? 5.How fast are you able to spin in a weightless environment? 6.Despite all your training and preparation for space, what is something aboutliving in space you didn't expect? 7.What is your favorite part about the ARISS program? 8.What are you currently researching? 9.What is the part of your job you look most forward to? 10.What is the most fun or interesting experiment you have conducted inspace? 11.Does sleeping in the sleeping bag trigger insomnia? 12.Do you ever get claustrophobic? 13.Which NASA project do you feel is the most important to us as human beings? 14.When did or what made you first realize you wanted to be an astronaut? 15.What's the most beautiful view you've seen from space? 16.How many repairs do you usually do to/on the space station daily? 17.If able to access music in space, what types do you usually listen to? 18.Is there a food you think is better in space than Earth? 19.Are plants grown aboard the ISS similar in size as the same plant grown onEarth? 20.What is your favorite 'trick' to do in a weightless environment? About ARISS: Amateur Radio on the InternationalSpace Station (ARISS) is a cooperative venture of international amateur radiosocieties and the space agencies that support the International Space Station(ISS). In the United States, sponsors are the Radio Amateur SatelliteCorporation (AMSAT), the American Radio Relay League (ARRL), the ISS NationalLab-Space Station Explorers, Amateur Radio Digital Communications (ARDC) andNASA’s Space Communications and Navigation program (SCaN). The primary goal ofARISS is to promote exploration of science, technology, engineering, the arts,and mathematics topics. ARISS does this by organizing scheduled contacts viaamateur radio between crew members aboard the ISS and students.

Detail on Cache district school contact
by Loren M. Lang 05 Feb '23

05 Feb '23

Are the questions for Tuesday's ISS School contact posted somewhere or possibly a live feed? Also, I had noticed last week that the beginning of contact time as predicted on N2YO.com was about 4 minutes earlier than the ARISS bulletin had it. Now that it's a few days later, N2YO has an updated AOS time that is much closer to the time on ARISS which hasn't changed. I originally assumed that N2YO would be more accurate than the time posted on a static timeline, but now I'm wondering if ARISS has more insider details than are available from the public TLEs or if N2YO was just using an older data source. -Loren K7IW

While a miraculous return is always possible, it is not expected. AO-95, known prior to launch as Fox-1Cliff to commemorate amateur satellite pioneer Cliff Buttschardt, K7RR, who became a silent key in 2007, launched on December 3, 2018 on a SpaceX Falcon 9 from Vandenburg Air Force Base. Shortly after deployment, the AMSAT Engineering team received nominal telemetry data from the satellite, but upon the first attempts at commanding, it was discovered that the receiver had failed for unknown reasons. Still, the satellite provided an easy to receive beacon and telemetry data for over four years before the NiCd batteries failed.

First is the massively popular new MEO satellite IO-117. Burt DeMarcq, FG8OJ, worked Shigenori Nasu, JH8FIH, on November 25, 2022 at 08:22 UTC. The distance between FG8OJ in FK96hg63 in Guadeloupe and JH8FIH in QN14qi16 in Japan is 12,823 km. Note that for future claims of IO-117, only live QSOs may be counted and not those completed over multiple orbits using the satellite's delayed messaging capabilities. A new distance record was also claimed via the QO-100 geostationary satellite. PT9AL in GG27os in Brazil worked XW4KV in Laos OK27jj on December 10, 2022 at 14:41 UTC. The distance between the two stations is 17,834 km, eclipsing the previous record held by PR8KW and YC5YC of 17,378 km. Finally, FO-118, launched in December is a LEO satellite carrying three transponders. Familiar faces for the AMSAT Satellite Distance Records have claimed the initial record on all three transponders - the V/u FM transponder, the V/u linear transponder, and the H/u linear transponder (15 meter uplink). F4DXV and VE1CWJ completed transatlantic QSOs on all three transponders. On January 6, 2023 at 04:15 UTC, they completed a QSO via the V/u FM transponder and then switched over to the V/u linear transponder to complete a QSO there one minute later. VE1CWJ was in FN85do83sg and F4DXV was in JN04js20pr. They completed the sweep of all three transponders on January 30, 2023, when they completed a QSO via the H/u linear transponder at 17:16 UTC. VE1CWJ was in the same location while F4DXV was in JN04it22nt for this QSO, for a distance of 4,908 km. Anyone who wants to claim a distance record via an amateur satellite should check the current list at https://www.amsat.org/satellite-distance-records/ and email n8hm at arrl.net if they complete a new record distance. Audio and/or video of the QSO is encouraged but not required.

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. More information may be found at https://www.amsat.org/keplerian-elements-resources/ AMSAT IT, in conjunction with the New England Sci-Tech STEM Education Center assembled a tiger team of software experts from the Olin College of Engineering, Boston Latin School and the Wilson Middle School to investigate the recent disappearance of AO-7 from www.amsat.org/tle/current/dailytle.txt and the legacy naasbare.txt files. The team determined that AMSAT's processing is not robust in the face of minor format differences in the source data received from the USSF's 18th Space Defense Squadron. Specifically, the TLE data provided does not always include the leading zero in AO-7's object number "07530". The official report from the team's leader : "My grandma would say that AMSAT's software is just a little too persnickety". A member of the tiger team agreed to adjust the update script to account for the vagaries of the 18th SDS data. A production quality fix is expected by March 1st, meanwhile manual monitoring and updates will keep AO-7 in the files. There were no changes to the February 2, 2023 distribution.

Thanks to following stations: AB1OC, IK1SLD, K6DUE, NA7V, ON4ISS, VK4ISS, VK4KHZ, VK5ZAI, VK6MJ, and ZS6JON. The crossband repeater continues to be active. 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. 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 0730 - 1930 UTC.

I had added a remote-control option to an old Yaesu G-450XL, but the output voltage was very non-linear, which led to terrible aiming of the antennas. With the mods I made to the firmware it now allows me to calibrate the controller at 0, 90, 180, 270, and 360 degrees and aiming is now rather accurate.

Re: EME with DL7APV

David, THANK YOU for posting this to AMSAT-BB. I’ve often wanted to try EME and I’ve been collecting parts to put together a separate EME station, but hadn’t had time to get that done yet. I’ve been on FT4/FT8 on HF and VHF/UHF so I already had WSJT-X installed. After seeing your post, I looked at DL7APV’s website and configured Q65-60B at the last minute. I decided to check the horizon at moonrise with my 18 element yagi before switching to the satellite antennas and was amazed to see DL7APV calling CQ. I answered and couldn’t hardly believe it when he answered! My first ever EME QSO is now in the log, and it will remain one of my most memorable QSO’s for a long time! 230202_213400 432.062 Rx Q65-60B -25 2.7 2523 CQ DL7APV JO62 q3 230202_213500 432.062 Tx Q65-60B 0 0.0 1500 DL7APV N9FN EN60 230202_213600 432.062 Rx Q65-60B -24 2.7 2522 N9FN DL7APV -25 q3 230202_213700 432.062 Tx Q65-60B 0 0.0 1500 DL7APV N9FN R-24 230202_213800 432.062 Rx Q65-60B -25 2.7 2520 N9FN DL7APV RR73 q3 230202_213900 432.062 Tx Q65-60B 0 0.0 1500 DL7APV N9FN 73 230202_214000 432.062 Rx Q65-60B -24 2.8 2518 CQ DL7APV JO62 q3 Thanks again and 73, Dave – N9FN From: David G0MRF via AMSAT-BB <amsat-bb(a)amsat.org> Sent: Wednesday, February 1, 2023 7:06 AM To: amsat-bb(a)amsat.org Subject: [AMSAT-BB] EME with DL7APV Just found this on Twitter.

Nice! A number of us who have assembled stations to work IO-117 have now worked DL7APV on 70cm EME. Other workable superstations may be on this weekend. In my case, the QSO was portable with a 15 el Yagi, pre-amp, and 50w at the antenna. A couple of ops found they could hear Bernd, but not be heard. That was fixed when they adjusted their polarization angle off of horizontal to account for spatial offset and Faraday rotation. See the Twitter thread and Q65 documentation for more on that.
