I would do that trouble-shooting procedure others have suggested to isolate the problem. We will all be interested in knowing what you discover. I had a somewhat similar issue with my G-5400B back in August 2014 for an ARISS contact in Fontana, California, that I mentored and loaned all of the equipment for. The air temp was about 100F and we had tested the entire antenna system an orbit before. But when I went to pre-position the rotors before our contact pass, the azimuth failed to move. We did a mad scramble up to the roof to see if something had failed and it was obvious something was not right in the Azimuth rotor. We re-aligned the tripod with the antennas when we realized that we could run just the elevation rotor and rely on the 30 degree beam width of the beam. As near we could tell, the rotors had been in direct sunlight on the roof and the temperature inside the rotor housing was probably high enough that when we ran the azimuth rotor, the heat build up from the motor operating and the sun was enough to thermal out the motor. The G-5400B schematic does show a thermal overload that I think opened up. After the contact and once I was home I tried the rotor again and the azimuth still did not operate. A few days later I took it into Yaesu for repair and they couldn't find anything wrong. My guess is that the thermal overload finally cooled down enough and remade contact. Since then I have not had an issue like this one. Something to consider is the thermal overload opening up and taking a long time to reset. 73,Charlie Sufana AJ9NOne of the ARISS mentors In a message dated 2023-08-13 10:26:40 Eastern Daylight Time, amsat-bb(a)amsat.org writes: The first thing to do is to isolate the problem.

I had an issue with my then 2 year old 5500. I was testing it to try and find the issue and I noticed the motor was running , but not moving the antenna. My problem was the dreaded drive gear set screw loose issue. I had to almost completely take the rotor apart to get to the set screw on the drive gear to tighten and apply some loctite to it. It's been working fine now for 5 years or so. Before you take it down to work on test for this... 73 Jeff kb2m

I'm used to checking the 5400 series rotors. A quick check I have used is to swap the AZ and EL connections on the rotor control box. If the AZ rotor moves using the EL control the problem is in the control box. If it doesn't move I'd do the continuity check of the motor leads, they should match the EL readings pretty close. At least those checks can be done on the ground. Good luck//Dave WB9YIG ________________________________ From: Mike Herr via AMSAT-BB <amsat-bb(a)amsat.org> Sent: Sunday, August 13, 2023 8:57 AM To: vimone(a)alice.it <vimone(a)alice.it> Cc: Amsat - BBs <amsat-bb(a)amsat.org> Subject: [AMSAT-BB] Re: Issue with Yaesu G-5500 Assuming the cable connections between the yaesu control box and the rotor is intact, it may be the motor driving the azimuth.

NASA made the announcement on August 4. NASA astronauts Commander Matthew Dominick, KC0TOR; Pilot Michael Barratt, KD5MIJ; and Mission Specialist Jeanette Epps, KF5QNU; along with Roscosmos cosmonaut Mission Specialist Alexander Grebenkin, will join Expedition 70 and 71 crew members aboard the station in early 2024 to conduct a wide-ranging set of operational and research activities. This will be the first spaceflight for Dominick, who became a NASA astronaut in 2017. He is from Wheat Ridge, Colorado, and earned a bachelor’s degree in electrical engineering from the University of San Diego, California, and a master’s in systems engineering from the Naval Postgraduate School in Monterey, California. He is an active-duty U.S. Navy astronaut. He graduated from the U.S. Naval Test Pilot School in Patuxent River, Maryland, and then served as a test pilot specializing in testing landing on and catapult launches from U.S. Navy aircraft carriers. This will be Barratt’s third trip to the space station. In 2009, Barratt served as a flight engineer for Expeditions 19 and 20 as the station transitioned its standard crew complement from three to six, and performed two spacewalks. He flew aboard the space shuttle Discovery in 2011 on STS-133, which delivered the Permanent Multipurpose Module and fourth Express Logistics Carrier. He has spent a total of 212 days in space. Born in Vancouver, Washington, he Considers Camas, Washington, to be his hometown. Barratt earned a bachelor’s in zoology from the University of Washington, Seattle, and a doctor of medicine from Northwestern University in Chicago, Illinois. He completed residencies in internal medicine at Northwestern and aerospace medicine along with a master’s degree at Wright State University in Dayton, Ohio. After nine years as a NASA flight surgeon and project physician, Barratt joined the astronaut corps in 2000. This also will be Epps’ first trip to the space station. She is from Syracuse, New York, and earned a bachelor’s in physics from LeMoyne College in Syracuse, New York, and a master’s in science and a doctorate in aerospace engineering from the University of Maryland, College Park. Prior to joining NASA, she worked at Ford Motor Company and the Central Intelligence Agency. She was selected as an astronaut in July 2009, and has served on the Generic Joint Operation Panel working on space station crew efficiency, as a crew support astronaut for two expeditions, and as lead capsule communicator in the Mission Control Center at NASA’s Johnson Space Center in Houston. Epps previously was assigned to NASA’s Boeing Starliner-1 mission. NASA reassigned Epps to allow Boeing time to complete development of Starliner while also continuing plans for astronauts to gain spaceflight experience for future mission needs. Grebenkin, who graduated from Irkutsk High Military Aviation School, Irkutsk, Russia, majoring in engineering, maintenance, and repair of aircraft radio navigation systems, also is flying on his first mission. He graduated from Moscow Technical University of Communications and Informatics with a degree in radio communications, broadcasting, and television. This is the eighth rotational mission to the space station under NASA’s Commercial Crew Program, which works with the American aerospace industry to provide safe, reliable, and cost-effective transportation to and from the orbital outpost on American-made rockets and spacecraft launching from American soil.

The downlink frequency on which to listen is 145.800 MHz worldwide. No contacts are currently scheduled due to summer school holidays. 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). 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 process of flight crew health stabilization is a routine part of final preparations for all missions to the space station. Spending the final two weeks before liftoff in quarantine will help ensure Crew-7 members are healthy, as well as protect the astronauts already on the space station. Commander Jasmin Moghbeli, KI5WSL; Danish ESA pilot Andreas Mogensen, KG5GCZ; JAXA mission specialist Satoshi Furukawa, KE5DAW; and cosmonaut Konstantin Borisov are now scheduled to launch to the International Space Station on August 25. (ANS thanks NASA for the above information) + Two Russian Cosmonauts conducted a spacewalk on August 9 Wednesday to to attach three debris shields to the Rassvet module on the International Space Station. Cosmonauts Sergey Prokopyev and Dmitri Petelin also tested the sturdiness of a work platform that will be affixed to the end of the European robotic arm attached to the Nauka multipurpose laboratory module. NASA livestreamed the seven hour spacewalk on YouTube, its website and on the NASA app. As always, ARISS amateur radio operations were suspended during the EVA. (ANS thanks Space Daily for the above information) + Russia reignited its moon exploration program on August 10, sending a lander toward Earth's nearest neighbor. The Luna-25 mission lifted off at 23:10 GMT after being delayed for nearly two years. The launch picked up where the former Soviet Union left off in 1976, when Luna-24 successfully delivered about 6.2 ounces (170 grams) of moon samples to Earth. But that was then. Luna-25 is the first domestically produced moon probe in modern Russian history. If all goes according to plan, Luna-25 will spend the next five days journeying to the moon, then circle the natural satellite for another five to seven days. The spacecraft will then set down in the moon's south polar region, near Boguslawsky Crater. Once down safe and sound, Luna-25 will work on the lunar surface for at least one Earth year. (ANS thanks Space.com for the above information) + Also in the race to land on the moon, India's Chandrayaan-3 lunar lander has returned its first images from the moon after entering orbit around our nearest neighbor. The Indian Space Research Organisation (ISRO) released the images on Sunday, August 6, showing that the spacecraft had reached its destination ahead of a lunar landing attempt expected on Aug. 23. If it's successful, India will join the United States, the former Soviet Union and China as the only nations to perform a soft lunar landing. (ANS thanks Space.com for the above information) + Virgin Galactic conducted its second-ever commercial mission on August 10, setting a number of spaceflight records in the process. The company launched its "Galactic 02" flight, sending six people to suborbital space and back. Four of them were women, setting a new mark for most women on a single spaceflight, according to Virgin Galactic. They included the first mother-daughter duo (one of whom became the youngest-ever spaceflyer), as well as the first former Olympian, to reach space.
