With commander Barry “Butch” Wilmore and co-pilot Sunita Williams, KD5PLB, monitoring the Starliner’s automated approach, the Starliner’s docking mechanism engaged its counterpart on the front of the station’s forward Harmony module at 17:34 UTC on June 8 as the two spacecraft were sailing 260 miles above the Indian Ocean. After extensive checks to verify an airtight seal, hatches were opened and Wilmore and Williams floated into the lab complex to an enthusiastic welcome from the seven Expedition 71 crew members: cosmonauts Oleg Kononenko, RN3DX, Nicolai Chub and Alexander Grebenkin, RZ3DSE, along with NASA astronauts Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Tracy Dyson. Wilmore and Williams plan to spend about a week aboard the outpost before returning to Earth aboard the Starliner. While they’re there, the station crew will install a replacement urine processor pump module that was loaded aboard the Starliner at the last minute to fix the lab’s water recycling system and allow normal use of the toilet in the U.S. segment of the station. Running years behind schedule after multiple problems that cost Boeing some $1.4 billion to correct, the Starliner was launched Wednesday with a known helium leak in the system used to pressurize the spacecraft’s propulsion system. Launch had been delayed a month, in part because of work to confirm the ship could safely be launched with the leak as is. After reaching orbit, two more helium leaks developed that prompted flight controllers to close valves leading to the affected plumbing, or manifolds, while they analyzed leak rates and potential work arounds. Closing the manifolds took down five of 28 reaction control system jets in the ship’s service module and three of 20 more powerful “OMAC” thrusters. Docking had to be delayed because five RCS jets were “deselected” by the capsule’s flight software when telemetry showed they were not performing exactly as expected. It was unclear if there would be sufficient maneuverability for the docking to proceed. Throughout the process, Wilmore flew the Starliner manually, holding position about 650 feet from the space station. When ground teams concluded the spacecraft had enough thruster redundancy to proceed, the Starliner’s automated control system took over and flew the ship in for a problem-free docking. As if the team hadn’t had enough problems to deal with, a fourth and a fifth helium leaks were detected after docking. In any case, per standard procedure, flight controllers closed all the Starliner’s helium manifolds after the linkup to prevent any residual leakage while attached to the station. Despite the leaks, NASA officials said more than enough helium remains on board to ensure a safe return to Earth at the end of a normal-duration or even extended mission. On June 14, NASA and Boeing teams pushed back the target undocking and landing date for the Starliner spacecraft from the International Space Station by four days. They shifted from June 18 to now no earlier than June 22. The reason for the extended stay is in part due to a need to gather more information about the Starliner capsule with the benefit of having an astronaut crew assigned to study aspects of the spacecraft with additional detail. The helium leaks are all located in the Starliner’s drum-shaped service module, which is discarded to burn up in the atmosphere before the crew capsule re-enters for landing. Thus, there is no possibility of post-flight analysis of the problems. [ANS thanks Spaceflight Now for the above information] The 2024 AMSAT President’s Club coins are here now!

NASA engineers have succeeded in breathing new life into Voyager 1, the spacecraft launched in 1977 and once again communicating after it went silent seven months ago. But now comes another challenge: Keeping Voyager 1 scientifically useful for as long as possible as it probes a realm where no spacecraft has gone before. Voyager 1 and its twin, Voyager 2, are treasured at NASA not only because they have sent home astonishing images of the outer planets, but also because in their dotage, they are still doing science that can’t be readily duplicated. They are now in interstellar space, far beyond the orbits of Neptune and Pluto. Voyager 1 is more than 15 billion miles from Earth and Voyager 2 nearly 13 billion miles. Both have passed the heliopause, where the “solar wind” of particles streaming from the sun terminates. “They’re going someplace where we have nothing, we have no information,” NASA Deputy Administrator Pam Melroy said. “We don’t know anything about the interstellar medium. Is it a highly charged environment? Are there a lot of dust particles out there?” Ed Stone, who guided the mission from 1972 until 2022, died on June 9. (Luis Sinco/Los Angeles Times/Getty Images) Even as the Voyagers continue their journeys, engineers and scientists at the NASA Jet Propulsion Laboratory in Pasadena, Calif. are mourning the loss of Ed Stone, the scientist who guided the mission from 1972 until his retirement in 2022. Stone, a former director of JPL, died June 9 at the age of 88. Voyager 1 has four scientific instruments still operational in this extended phase of its mission, but it suddenly ceased sending intelligible data on Nov. 14. A “tiger team” of engineers at JPL spent the ensuing months identifying the problem — a malfunctioning computer chip — and restoring communication. What no one can change, though, is the mortality of a spacecraft with a limited power supply. Voyager 1 is running on fumes, or, more precisely, on the dwindling power from the radioactive decay of plutonium. The Voyagers use a radioisotope thermoelectric generator. But an RTG doesn’t last forever. Voyager 1 and Voyager 2 will eventually go silent as they continue to cruise the galaxy. “At some point, we’ll have to start turning off the science instruments one by one,” project scientist Linda Spilker said. “Once we’re out of power, then we can no longer keep the spacecraft pointed at the Earth. And so [the Voyagers] will then continue on as what I like to think of as our silent ambassadors.” In a sense, this is all a bonus because the primary mission for the two Voyagers was the exploration of the outer planets. Both visited Jupiter and Saturn, and Voyager 2 went on to Uranus and Neptune in what was known as the “Grand Tour” of the outer solar system, enabled by a rare orbital arrangement of the planets. The Voyagers delivered spectacular close-up images of the outer planets, and the mission ranks among NASA’s greatest achievements. The gravitational slingshot from the planetary encounters sent Voyager 1 out of the elliptical plane of the solar system and did the same to Voyager 2 in a different direction. About four years ago, Voyager 1 encountered something unexpected — a phenomenon scientists have dubbed a pressure front. Jamie Rankin, deputy project scientist, said the instruments on the spacecraft picked up a sudden change in the magnetic field of the interstellar environment, as well as a sudden increase in the density of particles. What exactly caused this change remains unknown. But NASA scientists are eager to get all the data flowing normally again to see whether the pressure front is still detectable.

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 AMSAT for the above information.] The 2024 AMSAT Field Day Rules The AMSAT Field Day 2024 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital. Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM satellite. Operators are encouraged not to make any extra contacts via theses satellites (Ex: SO-50). CW contacts and digital contacts are worth three points as outlined below. Analog Transponders ARRL rules apply, except: Each phone, CW, and digital segment ON EACH SATELLITE TRANSPONDER is considered to be a separate band. CW and digital (FT-4, RTTY, PSK-31, etc.) contacts count THREE points each. Stations may only count one (1) completed QSO on any single channel FM satellite. If a satellite has multiple modes such as V/u and L/s modes both turned on, one contact each is allowed. If the both ISS stations are operational, one QSO on each mode (1 phone and 1 digital), Contacts with the ISS crew will count for one contact if they are active. Greencube (1 digital). The use of more than one transmitter at the same time on a single satellite transponder is prohibited. Digital Transponders Satellite digipeat QSO's and APRS short-message contacts are worth three points each, but must be complete verified two-way exchanges. The one contact per FM satellite is not applied to digital transponders. The use of terrestrial gateway stations or internet gateways (i.e. EchoLink, IRLP, etc.) to uplink/downlink is not allowed. For 'Store and Forward' hamsats, each satellite is considered a separate band. Do not post "CQ" messages. Simply upload ONE greeting message to each satellite and download as many greeting messages as possible from each satellite. The subject of the uploaded file should be posted as Field Day Greetings, addressed to ALL. The purpose of this portion of the competition is to demonstrate digital satellite communications to other Field Day participants and observers. Do not reply to the Field Day Greetings addressed to ALL. The following uploads and downloads count as three-point digital contacts. (a) Upload of a satellite Field Day Greetings file (one per satellite). (b) Download of Satellite Field Day Greetings files posted by other stations. Downloads of non-Field Day files or messages not addressed to ALL are not to be counted for the event. Save DIR listings and message files for later "proof of contact." You may make contacts with GreenCube, IO-117, and each one will count as 3 points as do other digital contacts. Please note AMSAT uploaded messages do not count for QSO points under the ARRL rules. Sample Satellite Field Day Greetings File: KK5DO FD EL29 class 2A 20 participants Note that the message stated the call, operating class, where they were located (the grid square) and how many operators were in attendance. Operating Class Stations operating portable and using emergency power (as per ARRL Field Day rules) are in a separate operating class from those at home connected to commercial power. On the report form simply check off Emergency or Commercial for the Power Source and be sure to specify your ARRL operating class (2A, 1C, etc.). AND FINALLY… The Satellite Summary Sheet should be used for submission of the AMSAT Field Day competition and be received by KK5DO (e-mail) by 11:59 P.M. CDT, Monday, July 23, 2024. This year, we are using the same due date as the ARRL. The only method for submitting your log is via e-mail to kk5do(a)amsat.org or kk5do(a)arrl.net. I have not had a mail-in entry in a very long time. Add photographs or other interesting information that can be used in an article for the Journal. You will receive an e-mail back (within one or two days) from me when I receive your e-mail submission. If you do not receive a confirmation message, then I have not received your submission. Try sending it again or send it to my other e-mail address. Certificates will be awarded for the first-place emergency power/portable station at the AMSAT General Meeting and Space Symposium in the fall of 2024. Certificates will also be awarded to the second and third place portable/emergency operation in addition to the first-place home station running on emergency power. A station submitting high, award-winning scores will be requested to send in dupe sheets for analog contacts and message listings for digital downloads. You may have multiple rig difficulties, antenna failures, computer glitches, generator disasters, tropical storms, and there may even be satellite problems, but the goal is to test your ability to operate in an emergency situation. Try different gear. Demonstrate satellite operations to hams that don't even know the HAMSATS exist. Test your equipment. Avoid making more than ONE contact via the FM-only voice HAMSATS or the ISS, and enjoy the event!

FS: Satellite related radios
by JOHN GEIGER 17 Jun '24

17 Jun '24

I am helping a local ham here (Claude KD5RQ) sell off his remaining ham radio gear, and he has available some radios related to the satellites that I am offering for sale. Prices included shipping in the US and paypal/check/MO/cash can be used for payment. I can send lots of photos of each item, and will do my best to describe each one below. 1. Heathkit HW-24H Have you ever heard another ham say he is using a Heathkit on the satellites? I haven't, but here is your chance to be that ham! No, I did not assemble this myself. Standard (before they were bought by Yaesu) built these for Heathkit, and Standard made the high end FM radios in the 1990s. This radio shows it-built very tough and an excellent receiver, little or no intermod with this one. This is the same as the Standard C5200-https://www.rigpix.com/standard/c5200d.htm. This radio does dual receive, full duplex, 50 watts on 2m and 40 watts on 70cm, transmits in the satellite portion of 70cm if you want to use it for that, and has tone encode but not tone decode. It has separate antenna jacks on pigtails for 2m and 70cm, and the receive audio on this is top notch. It has separate speaker jacks for 2m and 70cm also. The case is in good condition with one small scrape on the bottom, and a sticker with some public service memories or so on the top. It comes with a TTP mic, power cord, and original box. The manual is available on-line. Asking $200 2. Yaesu FT8000 Mode J radio. I am calling this a mode J radio because it transmits fine on 2m-50 watts out. It transmits and receives fine on 70cm-35 watts out. It just doesn't receive much on 2m. It did pick up my HT on receive, but would not receive the local repeaters. So it is good to use on the ISS, Tevel 1-8, Lilacsat-2, UVSQ-Sat, and SO121, any satellite where you transmit on 2m and receive on 70cm. It does full duplex and will do cross band repeat also. It has the mic, power cord, and mobile bracket. Great small portable Mode J rig. Pair it up with one of the 2m radios below for full duplex with receive on 2m. Asking $110. 3. Yaesu FT480R 2 meter all mode. This would make a good uplink for RS-44, and AO7 Mode A, or downlink with JO97 and AO7 Mode B. It does 10 watts SSB/CW/AM/FM. Doesn't have tone encode for FM but does have a jack to add an encoder. This thing is built like a tank-back from when all radios were! It comes with a mic and power cord. Asking $150. 4. Yaesu FT2200. 2 meter FM, 50 watts out, uses a round pin mic (included). Has some velco on the case, probably from mounting it to something. Has mic and power cord, and I believe a mobile bracket. Asking $95 5. Radio Shack HTX-242 very small 2m 45 watt FM rig. Own a piece of history by owning a Radio Shack rig! Has a little velco on the case also. Has power cord, and mobile bracket. It has a working mic but you will want to replace the mic cord as the rubber on it has completel disingrated (must have been made by Yaesu). Has original box also. I believe the mobile bracket is unused. Asking $60. 6. Radio Shack HTX-10 10 meter SSB/AM/FM radio. Use this with #3 for AO7 mode A QSOs, or use it to drive a transverter in your satellite setup. Comes with mic and power cord. Does around 24 watts or so. Good condition overall. Asking $80. So there is what is available. Pair the 2m rigs with your Baofeng HT to do full duplex, or use these in some other combination 73 John AF5CC

Tuning a circular polarized antenna?
by Chad KG0MW 17 Jun '24

17 Jun '24

So I just built my M2 yagis for 2m and 70cm. They are both circular polarized. My question is what is the proper way to tune the vertical and horizontal planes? I have always just unplugged one set from the splitter and tuned each plane on its own. But what about when you unplug one phasing cable you are leaving one port open. Does that make sense? Anyway I am just wondering if someone would share how they tune a CP yagi. Thanks Chad KG0MW

FS: Yaesu FT8800 dualband FM radio-great for sats
by JOHN GEIGER 16 Jun '24

16 Jun '24

I have for sale a Yaesu FT8800 2m/70cm FM dualband radio in very good condition. This model does dual receive, crossband repeat, 50 watts on 2m and 35 watts on 70cm. Also does wide receive and lots of memories plus 6 hyper memories which are great for the FM satellites or your local favorite repeaters. It is just a very easy to use dualbander which Yaesu sold for a long time due to its good performance. You set the satellite uplink and downlinks, push and hold the hyperlink button, and then every time you push that button it returns to that setup. I already have the active FM satellites programmed in. It works great, I have been using it on the FM satellites with great results. The traditional 2 pin power plug on the pigtail has been replaced with Anderson power poles. It comes with the hand mic and power cord. I am asking $225 shipped and can take paypal/check/MO. I have a YSK-8900 seperation kit and mobile bracket I can include for $30 more. 73 John AF5CC Sent using {0}

With commander Barry “Butch” Wilmore and co-pilot Sunita Williams, KD5PLB, monitoring the Starliner’s automated approach, the Starliner’s docking mechanism engaged its counterpart on the front of the station’s forward Harmony module at 17:34 UTC on June 8 as the two spacecraft were sailing 260 miles above the Indian Ocean. After extensive checks to verify an airtight seal, hatches were opened and Wilmore and Williams floated into the lab complex to an enthusiastic welcome from the seven Expedition 71 crew members: cosmonauts Oleg Kononenko, RN3DX, Nicolai Chub and Alexander Grebenkin, RZ3DSE, along with NASA astronauts Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Tracy Dyson. Wilmore and Williams plan to spend about a week aboard the outpost before returning to Earth aboard the Starliner. While they’re there, the station crew will install a replacement urine processor pump module that was loaded aboard the Starliner at the last minute to fix the lab’s water recycling system and allow normal use of the toilet in the U.S. segment of the station. Running years behind schedule after multiple problems that cost Boeing some $1.4 billion to correct, the Starliner was launched Wednesday with a known helium leak in the system used to pressurize the spacecraft’s propulsion system. Launch had been delayed a month, in part because of work to confirm the ship could safely be launched with the leak as is. After reaching orbit, two more helium leaks developed that prompted flight controllers to close valves leading to the affected plumbing, or manifolds, while they analyzed leak rates and potential work arounds. Closing the manifolds took down five of 28 reaction control system jets in the ship’s service module and three of 20 more powerful “OMAC” thrusters. Docking had to be delayed because five RCS jets were “deselected” by the capsule’s flight software when telemetry showed they were not performing exactly as expected. It was unclear if there would be sufficient maneuverability for the docking to proceed. Throughout the process, Wilmore flew the Starliner manually, holding position about 650 feet from the space station. When ground teams concluded the spacecraft had enough thruster redundancy to proceed, the Starliner’s automated control system took over and flew the ship in for a problem-free docking. As if the team hadn’t had enough problems to deal with, a fourth and a fifth helium leaks were detected after docking. In any case, per standard procedure, flight controllers closed all the Starliner’s helium manifolds after the linkup to prevent any residual leakage while attached to the station. Despite the leaks, NASA officials said more than enough helium remains on board to ensure a safe return to Earth at the end of a normal-duration or even extended mission. On June 14, NASA and Boeing teams pushed back the target undocking and landing date for the Starliner spacecraft from the International Space Station by four days. They shifted from June 18 to now no earlier than June 22. The reason for the extended stay is in part due to a need to gather more information about the Starliner capsule with the benefit of having an astronaut crew assigned to study aspects of the spacecraft with additional detail. The helium leaks are all located in the Starliner’s drum-shaped service module, which is discarded to burn up in the atmosphere before the crew capsule re-enters for landing. Thus, there is no possibility of post-flight analysis of the problems.

NASA engineers have succeeded in breathing new life into Voyager 1, the spacecraft launched in 1977 and once again communicating after it went silent seven months ago. But now comes another challenge: Keeping Voyager 1 scientifically useful for as long as possible as it probes a realm where no spacecraft has gone before. Voyager 1 and its twin, Voyager 2, are treasured at NASA not only because they have sent home astonishing images of the outer planets, but also because in their dotage, they are still doing science that can’t be readily duplicated. They are now in interstellar space, far beyond the orbits of Neptune and Pluto. Voyager 1 is more than 15 billion miles from Earth and Voyager 2 nearly 13 billion miles. Both have passed the heliopause, where the “solar wind” of particles streaming from the sun terminates. “They’re going someplace where we have nothing, we have no information,” NASA Deputy Administrator Pam Melroy said. “We don’t know anything about the interstellar medium. Is it a highly charged environment? Are there a lot of dust particles out there?” *Ed Stone, who guided the mission from 1972 until 2022, died on June 9. (Luis Sinco/Los Angeles Times/Getty Images)* Even as the Voyagers continue their journeys, engineers and scientists at the NASA Jet Propulsion Laboratory in Pasadena, Calif. are mourning the loss of Ed Stone, the scientist who guided the mission from 1972 until his retirement in 2022. Stone, a former director of JPL, died June 9 at the age of 88. Voyager 1 has four scientific instruments still operational in this extended phase of its mission, but it suddenly ceased sending intelligible data on Nov. 14. A “tiger team” of engineers at JPL spent the ensuing months identifying the problem — a malfunctioning computer chip — and restoring communication. What no one can change, though, is the mortality of a spacecraft with a limited power supply. Voyager 1 is running on fumes, or, more precisely, on the dwindling power from the radioactive decay of plutonium. The Voyagers use a radioisotope thermoelectric generator. But an RTG doesn’t last forever. Voyager 1 and Voyager 2 will eventually go silent as they continue to cruise the galaxy. “At some point, we’ll have to start turning off the science instruments one by one,” project scientist Linda Spilker said. “Once we’re out of power, then we can no longer keep the spacecraft pointed at the Earth. And so [the Voyagers] will then continue on as what I like to think of as our silent ambassadors.” In a sense, this is all a bonus because the primary mission for the two Voyagers was the exploration of the outer planets. Both visited Jupiter and Saturn, and Voyager 2 went on to Uranus and Neptune in what was known as the “Grand Tour” of the outer solar system, enabled by a rare orbital arrangement of the planets. The Voyagers delivered spectacular close-up images of the outer planets, and the mission ranks among NASA’s greatest achievements. The gravitational slingshot from the planetary encounters sent Voyager 1 out of the elliptical plane of the solar system and did the same to Voyager 2 in a different direction. About four years ago, Voyager 1 encountered something unexpected — a phenomenon scientists have dubbed a pressure front. Jamie Rankin, deputy project scientist, said the instruments on the spacecraft picked up a sudden change in the magnetic field of the interstellar environment, as well as a sudden increase in the density of particles. What exactly caused this change remains unknown. But NASA scientists are eager to get all the data flowing normally again to see whether the pressure front is still detectable.

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 AMSAT for the above information.] ------------------------------ The 2024 AMSAT Field Day Rules The AMSAT Field Day 2024 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital. Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM satellite. Operators are encouraged not to make any extra contacts via theses satellites (Ex: SO-50). CW contacts and digital contacts are worth three points as outlined below. *Analog Transponders* ARRL rules apply, except: Each phone, CW, and digital segment ON EACH SATELLITE TRANSPONDER is considered to be a separate band. CW and digital (FT-4, RTTY, PSK-31, etc.) contacts count THREE points each. Stations may only count one (1) completed QSO on any single channel FM satellite. If a satellite has multiple modes such as V/u and L/s modes both turned on, one contact each is allowed. If the both ISS stations are operational, one QSO on each mode (1 phone and 1 digital), Contacts with the ISS crew will count for one contact if they are active. Greencube (1 digital). The use of more than one transmitter at the same time on a single satellite transponder is prohibited. *Digital Transponders* Satellite digipeat QSO's and APRS short-message contacts are worth three points each, but must be complete verified two-way exchanges. The one contact per FM satellite is not applied to digital transponders. The use of terrestrial gateway stations or internet gateways (i.e. EchoLink, IRLP, etc.) to uplink/downlink is not allowed. For 'Store and Forward' hamsats, each satellite is considered a separate band. Do not post "CQ" messages. Simply upload ONE greeting message to each satellite and download as many greeting messages as possible from each satellite. The subject of the uploaded file should be posted as Field Day Greetings, addressed to ALL. The purpose of this portion of the competition is to demonstrate digital satellite communications to other Field Day participants and observers. Do not reply to the Field Day Greetings addressed to ALL. The following uploads and downloads count as three-point digital contacts. (a) Upload of a satellite Field Day Greetings file (one per satellite). (b) Download of Satellite Field Day Greetings files posted by other stations. Downloads of non-Field Day files or messages not addressed to ALL are not to be counted for the event. Save DIR listings and message files for later "proof of contact." You may make contacts with GreenCube, IO-117, and each one will count as 3 points as do other digital contacts. Please note AMSAT uploaded messages do not count for QSO points under the ARRL rules. Sample Satellite Field Day Greetings File: KK5DO FD EL29 class 2A 20 participants Note that the message stated the call, operating class, where they were located (the grid square) and how many operators were in attendance. *Operating Class* Stations operating portable and using emergency power (as per ARRL Field Day rules) are in a separate operating class from those at home connected to commercial power. On the report form simply check off Emergency or Commercial for the Power Source and be sure to specify your ARRL operating class (2A, 1C, etc.). *AND FINALLY…* The Satellite Summary Sheet should be used for submission of the AMSAT Field Day competition and be received by KK5DO (e-mail) by 11:59 P.M. CDT, Monday, July 23, 2024. This year, we are using the same due date as the ARRL. The only method for submitting your log is via e-mail to kk5do(a)amsat.org or kk5do(a)arrl.net. I have not had a mail-in entry in a very long time. Add photographs or other interesting information that can be used in an article for the Journal. You will receive an e-mail back (within one or two days) from me when I receive your e-mail submission. If you do not receive a confirmation message, then I have not received your submission. Try sending it again or send it to my other e-mail address. Certificates will be awarded for the first-place emergency power/portable station at the AMSAT General Meeting and Space Symposium in the fall of 2024. Certificates will also be awarded to the second and third place portable/emergency operation in addition to the first-place home station running on emergency power. A station submitting high, award-winning scores will be requested to send in dupe sheets for analog contacts and message listings for digital downloads. You may have multiple rig difficulties, antenna failures, computer glitches, generator disasters, tropical storms, and there may even be satellite problems, but the goal is to test your ability to operate in an emergency situation. Try different gear. Demonstrate satellite operations to hams that don't even know the HAMSATS exist. Test your equipment. Avoid making more than ONE contact via the FM-only voice HAMSATS or the ISS, and enjoy the event!

The downlink frequency on which to listen is 145.800 MHz worldwide. *Postponed until fall 2024.:* Instituto de Aplicação Fernando Rodrigues da Silveira (CAp-UERJ) and The State University of Rio de Janeiro (UERJ), Rio de Janeiro, Brazil, direct via PY1AX The ISS callsign is presently scheduled to be NA1SS The scheduled crewmember is Jeanette Epps, KF5QNU. The ARISS mentor is VE3TBD. Contact is postponed until fall 2024. *The crossband repeater* continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). 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. *The packet system* is also active (145.825 MHz up & down). The HamTV and SSTV systems are currently stowed. *As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.* Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

The radome will once again be dedicated to satellite and space research. AMSAT Deutschland e.V. and the Bochum Observatory are taking the positive experience of the anniversary conference in 2023 as an opportunity to inform AMSAT members and other space enthusiasts about current and future prospects for national and international space projects with a varied program. As the Radom is also the location of ESA’s education office in Germany (esero Germany), a goal is to make the symposium even more attractive in future and at the same time focus even more on current European space travel. [ANS thanks AMSAT-DL for the above information.] + SpaceX’s enormous rocket took off again from South Texas on June 6, this time with the sole goal of bringing both the booster and ship softly back to Earth in (roughly) single pieces. An on-time launch of the world’s most powerful rocket delivered excitement from start to finish. Despite an engine out on launch and landing (with 33 engines total, Superheavy doesn’t care), the first stage was able to complete a nominal ascent, hot-staging, temporary hot-staging ring jettison, boost back, and landing burn—all with enough precision that previously deployed buoy cams were able to capture its soft splashdown. [ANS thanks The Orbital Index for the above information.] + Russian cosmonaut and ISS commander Oleg Konenko became the first person to reach 1,000 cumulative days in space as of June 4. The milestone comes amid his fifth flight to space and during his third stint as the commander of the ISS. His most recent trip to the orbiting laboratory began with a launch aboard the Soyuz MS-24 spacecraft on Sept. 15, 2023, alongside cosmonaut Nikolai Chub and NASA astronaut Loral O’Hara, KI5TOM. He’s scheduled to return with Chub and NASA astronaut Tracy Dyson in September 2024.
