*Not to get too far off topic, but this is the kind of thing that an SDR in orbit could help hunt down. Imagine one of the GOLFs, with is SDR capability.....* Yes, with its very own NROL-37, AMSAT could make enough money to put a lot of satellites in orbit! Speaking of which, I'm sure there's a recording of the interfering stations *somewhere* already. KV1J, that would be awesome to test. Even just recording the repeater output if someone is talking during the pass might allow it to be correlated with a satellite recording. I was going to try on echolink, but it looks like the nodes are down. Maybe leave a radio on the input frequency sometime as well to see if anyone on baofengs shows up. -Stephen, N8URE

I ran the experiments for 2 passes. 28Apr 1608 UTC and 29Apr 0245 UTC. The first pass was just a few minutes before it switched to the video mode. The second pass was high elevation and 11 minutes. It was mentioned that the interference might be from a 145.110 MHz repeater due to the 3rd harmonic. Also mentioned were towns heard in the conversation and that there was a courtesy beep. A repeater in our area that fits all those items in the N1CON repeater in Concord MA. For both passes I heard the bird fine and there were ongoing QSOs. During the passes I transmitted periodically on the repeater announcing my call and 'testing' to cause some audio on the repeater. Also had another station transmitting on the repeater. Throughout the test I did not hear any interference on the downlink. So also, I did not listen to the uplink frequency since there did not seem to be any interference at that time. I am using different radios for TX and RX, and antennas that are far apart for the tests. I'll check from time to time listening to the downlink. If I hear the interference, I can both check the uplink frequency and also listen to the local repeaters. There are many in this area. 73, Eric KV1J FN42 (West of Boston MA) -----Original Message----- From: Eric Williams [mailto:[email protected]] Sent: Tuesday, April 28, 2020 11:14 AM To: 'amsat-bb(a)amsat.org' <amsat-bb(a)amsat.org> Subject: RE: Repeater interference on AO-92 Yes, I am also listening to the uplink freq. Next pass is in about 1 hour. 73 Eric KV1J (I use digest mode for this list so pardon the not including the string of messages) -----Original Message----- From: Eric Williams [mailto:[email protected]] Sent: Tuesday, April 28, 2020 10:51 AM To: 'amsat-bb(a)amsat.org' <amsat-bb(a)amsat.org> Subject: RE: Repeater interference on AO-92 I am in the area of a suspected repeater. Also in the area of the towns mentioned to could be that machine. I'll watch for the next AO-92 pass and announce my call of the repeater a few times and listen to AO-92. So if you hear "KV1J" it is me testing for the interference. I have not looked at the pass schedule yet but I can try a couple passes. 73, Eric KV1J FN42

ARISSNews Release No. 20-03 DaveJordan, AA4KN ARISSPR aa4kn(a)amsat.org FOR IMMEDIATE RELEASE Duringthe COVID-19 Pandemic, ARISS to Begin Experimental Demonstrations ofSchool Contacts using a Multipoint Telebridge Amateur Radio Approach April28, 2020—AmateurRadio on the International Space Station (ARISS) is pleased toannounce the first use of a concept called MultipointTelebridge Contact via Amateur Radio,allowing school contacts for Stay-At-Home students and simultaneousreception by families, school faculty and the public. Duringthe last several weeks, efforts to contain the spread of the COVID-19virus have resulted in massive school closures worldwide. Inaddition, the Stay-At-Home policies invoked by authorities, initiallyshut down opportunities for ARISS school contacts for the nearfuture. Tocircumvent these challenges and keep students and the public safe,ARISS is introducing the MultipointTelebridge Contact via Amateur Radio concept.First operation of this experimental system will occur during acontact scheduled with a group of Northern Virginia Studentslocated in Woodbridge, VA on Thursday, April 30 at 13:35 UTC (9:35EDT). During this event, an ARISS telebridge radio ground stationwill link to the astronaut on the International Space Station (ISS)ham radio station and each Stay-At-Home student and their teacherwill be individually linked to the telebridge station. Under theteacher’s direction, each student, from their home, takes a turnasking their question of the astronaut. QuotingARISS Chair Frank Bauer, “Thisapproach is a huge pivot for ARISS, but we feel it is a greatstrategic move for ARISS. In these times of isolation due to thevirus, these ARISS connections provide a fantastic psychologicalboost to students, families, educators and the public. And theycontinue our long-standing efforts to inspire, engage and educatestudent in STEAM subjects and encourage them to pursue STEAMcareers.” ARISSis inviting the public to view a live stream of the upcoming contactat its new ARISS YouTube Channel: https://youtu.be/Cu8I9ose4Vo. Duringthe contact, participants will ask as many of the following questionsas time allows: 1.What does the sun look like from outer space? 2.How comfortable is it to sleep in space? 3.What is one thing you want to eat when you get back to earth? 4.I've heard that stars are red, yellow and blue. Can you see thosecolors in space when you look at the stars? 5.Besides your family, what do you miss most while being in space? 6.What are your thoughts on our Covid-19 situation right now? Does theEarth look differently over the last 3 months now that many peopleare inside and not creating pollution? 7.How often do you get to go out of the ISS? Have you been on any spacewalks? 8.Who makes the rocket that takes you to the ISS? 9.What does it feel like to float all the time? 10.Do you use flashlights on space walks? 11.How do you exercise in space? 12.How do you get out for space walks safely without the air from theISS coming out into space? How does it feel to walk in space? 13.What do you wear in the space station? 14.How did it feel when you first got to space? 15.How is space different from Earth? 16.What do you study in school to become an astronaut? 17.What do you like the most about being in space? 18.Were you nervous when you launched into space? 19.How do you communicate with loved ones while you are in space? AboutARISS: AmateurRadio on the International Space Station (ARISS) is a cooperativeventure of international amateur radio societies and the spaceagencies that support the International Space Station (ISS). In theUnited States, sponsors are the Radio Amateur Satellite Corporation(AMSAT), the American Radio Relay League (ARRL), the ISS National Laband National Aeronautics and Space Administration (NASA). The primarygoal of ARISS is to promote exploration of science, technology,engineering, and mathematics (STEAM) topics by organizing scheduledcontacts via amateur radio between crew members aboard the ISS andstudents in classrooms or public forms. Before and during these radiocontacts, students, educators, parents, and communities learn aboutspace, space technologies, and amateur radio.

LoTW and PO-101
by Bob Meyers 29 Apr '20

29 Apr '20

I am using N3FJP's logging program to upload contacts to LoTW. It has been working very good on all satellites. However when I try and upload PO-101 it gets rejected by LoTW. Does anybody know what LoTW wants for this satellites name? I get a message back that says "invalid satellite name on line 41". Bob WA8FXQ
