This is to make all\npossible faults never allow more than 80 volts anywhere in the system.\nThis is effective 1 Jan 2019\n\nThis is the nail in the coffin of simple DC series string arrays\nwhich are\nthe quietest systems and almost demands microinverters or optimizers\non\nevery panel. Refer to the QST article a few years ago about how\ndisastrous\noptimizers are to RFI and HF operations with modules all over the\nroof..\n\nHere is the Solar news:\nhttps://solarbuildermag.com/bos/nec-2017-module-level-solar-system-\nshutdown/\n\nAlso, what is going to happen to an array that has signaling all\nover it in\nthe near field of HF?\n\nAlthough you can avoid it by going solar before then, you may have\nproblems\nwhen your neighbors go later.\n\nI hate to be an alarmist but we all know what happens when ham\nradio and\ncommercial systems are incompatible and even though Ham radio might\nbe in\nthe right, we are only 1 in 600 and no one is going to side with us.\n\nWe took on broadband over power and squelched that dumb idea, but\nnow this\nhas the potential for equal demise of Ham radio. It should be\nfixable, but\nwe also know that there is high competition in the solar market and\nthe\nmodules that are made the cheapest will be popular and will likely\nnot be\nadequately filtered.\n\nSorry for posting to the AMSAT-bb but it is the only HAM email\nreflector I\nsubscribe to.\n\nIf nothing else, we need to find out what systems are terrible\nemitters and\nnip them in the bud. Maybe all it takes is driving by solar systems\nyou\nsee and turing on your AM radio on a weak signal channel and seeing\nif the\nbackground noise peaks near that home. But also it has individual\npeaks,\nso it might also be nice to tune around too find the max and then\ncheck the\nrange. I find the noise can go hundreds of feet along the power\nlines....\n\nYou cant miss em... just sounds like a 60 Hz buzz on all the\nharmonics of\nthe inverter switching frequency.\n\n[ANS thanks Bob, WB4APR for the above information]\n\n---------------------------------------------------------------------\n\nUpcoming ARISS Contact Schedule 2018-05-04 07:30 UTC\n\nMill Springs Academy, Alpharetta, GA, direct via WA4MSA\nThe ISS callsign is presently scheduled to be NA1SS\nThe scheduled astronaut is Scott Tingle KG5NZA\nContact was successful for: Thu 2018-05-03 15:47:30 UTC 25 deg (***)\nStudents for the Exploration & Development of Space, College\nStation, TX, direct via W5QZ\nThe ISS callsign is presently scheduled to be NA1SS\nThe scheduled astronaut is Scott Tingle KG5NZA\nContact was successful for: Thu 2018-05-03 17:22:31 UTC 47 deg (***)\nMooreland Heights Elementary, Knoxville, TN, direct via WA4SXM/N4CFB\nThe ISS callsign is presently scheduled to be NA1SS\nThe scheduled astronaut is Ricky Arnold KE5DAU\nContact is a go for: Mon 2018-05-07 13:54:10 UTC 23 deg\n\n[ANS thanks Charlie, AJ9N, for the above information]\n\n---------------------------------------------------------------------\n\nEL58hx Grid Expedition - 25-27 May\n\nThe activation of maidenhead grid square EL58hx by W5PFG & AC0RA is\njust\nthree weeks away. Even if you are not a grid or awards chaser, we\nwould\nlove to work you during this expedition via satellite. There are no\npermanent residents of this grid square, as the majority of it is\nopen\nwater in the Gulf of Mexico. What little land in EL58 is sandbar at\nmouth of the Mississippi River and accessible only by boat. See here:\nhttp://qthlocator.free.fr/index.php?locator=el58hx\n\nDuring the entire expedition, we will be land-based in the grid,\nmeaning\nthis activation will count as Louisiana, Plaquemines Parish (County),\nUSA. It counts as Islands on the Air IOTA NA-168, Burwood Island. If\nyou\nparticipate in the 2018 ARRL International Grid Chase, this might be\nyour only opportunity to work EL58.\n\nOperating activity is estimated to begin around 23:00 UTC on 25 May.\nThere are some variability in our arrival time and it will take us\nsome\ntime to prepare the site for operation. We will likely conclude\noperations around 15:00 UTC on 27 May.\n\nThere are a total of 110 satellite passes predicted, 42 being FM.\nWhile\nwe won't work every one of those, we should be on the ones that fall\ninto good times and the best footprints over population centers. The\nlist below are satellites we plan to utilize:\n\nFM: SO-50, AO-85, AO-91, AO-92\nSSB: AO-7, FO-29, AO-73, XW-2A, XW-2B, XW-2C, XW-2F, CAS-4B\n\nSkeds are available for DX and stations greater than 6000 kms\ndistance\nfrom EL58hx. Sked via direct email only to w5pfg at arrl dot net.\n\nEven if you worked the previous EL58 trip (K5L/mm), we'd love to work\nyou again. This expedition we will use callsign W5PFG on satellites\nand\nAC0RA on 6m. We are hoping to work and confirm as many grid squares\nas\npossible, so if you want to work us from a nearby grid line to your\nhome\nQTH, it is appreciated!\n\nAC0RA is responsible for the 6m side of our activation. You may hear\neither of us on 20m and 40m. Any one who works us is encourage to\nspot us.\n\nI may activate other grids in route to EL58, especially Friday\nmorning\nthe 25th. I'll try to announce those via Twitter @w5pfg but it may\nbe on\nshort notice.\n\n[ANS thanks Clayton, W5PFG, for the above information]\n\n---------------------------------------------------------------------\n\nUK Unicorn-2a PocketQube + HuskySat-1 transponder frequencies\n\nUK Unicorn-2a PocketQube Satellite\nhttps://amsat-uk.org/2018/05/01/unicorn-2a-pocketqube-satellite/\n\nAmateur radio regulatory changes in Eire\nhttps://amsat-uk.org/2018/05/01/amateur-radio-regulatory-changes-in-\neire/\n\nHuskySat-1 Linear Transponder frequencies have been coordinated by\nIARU.\nAs well as the V/U transponder for SSB/CW the satellite also has a\ndownlink on 24 GHz\nhttp://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=604\n\nKing's High School ARISS contact on BBC TV\nhttps://amsat-uk.org/2018/04/19/kings-high-school-ariss-contact-bbc/\n\nEmily Calandrelli's new book aimed at young people - Ada Lace, Take\nMe to Your Leader - features amateur radio and space communication.\nSean Kutzko KX9X was an advisor for the book\nhttp://www.southgatearc.org/news/2018/may/ada-lace-book-features-ham-\nradio.htm\n\nAMSAT-EA May issue of English language newsletter now available\nhttps://www.amsat-ea.org/app/download/10352773/AMSAT-EA-\nNewsletter_05-2018.pdf\n\nAMSAT-UK http://amsat-uk.org/\nTwitter https://twitter.com/AmsatUK\nFacebook https://facebook.com/AmsatUK\nYouTube https://youtube.com/AmsatUK\n\n[ANS thanks Trevor, M5AKA, for the above information]\n\n---------------------------------------------------------------------\n\nVUCC Awards-Endorsements for April 2018\n\nHere are the endorsements and new VUCC Satellite\nAwards issued by the ARRL for the period April 1, 2018\nthrough May 1, 2018.\nCongratulations to all those who made the list this month!\n\nThere were two calls which decreased by one this month.\nI have reported these to ARRL.

The goal is not to be a comprehensive\nsource of amateur satellite information (especially not lists of all\nthe sats, as that info is on many other sources), just to supplement\nwhat is already out there and provide a place to collect commonly\nrequested information. More information on the intention/philosophy of\nthe wiki can be found here:\nhttp://sats.wikidot.com/about\n\nIf you want to add stuff or edit the wiki, please create an account on\nwikidot and let me or Brad know your username/email address and we can\nadd you.\n\nOn the To-Do list [1] I have a goal to make a new page with a list of\nfull duplex HTs. I know a list of these HTs already is on the web but\nI don't believe it's updated. I also know Patrick, WD9EWK has a lot of\ndetailed info on various Chinese radios.

AMSAT may file comments as well, though\nthe focus of those comments will be about any potential inference to\nthe Part 97, Amateur Radio Service. AMSAT and the ARRL have been in\ncontact discussing this Part 25 NPRM.
