After a trial period in which its\nbehavior has been tested at the radioelectric, systems, and energy\nperformance levels, the FM repeater is left active for general use.\n\nAt the request of AMSAT-EA, AMSAT has designated HADES-D as Spain-OSCAR 121\n(SO-121). AMSAT congratulates AMSAT-EA, thanks them for their contribution\nto the amateur satellite community, and wishes them continued success on\nthis and future projects.\n\nThe repeater works with FM/FSK (MSK144 has been tested too) with an uplink\nfrequency of 145,875 MHz and a downlink frequency of 436,663.5 MHz (a bit\nlower than the 436.666 MHz expected). We have been able to verify that the\nmodulation is more appropriate by narrowing the bandwidth, so it is\nrecommended to use NFM in those devices allowing it.\n\nAMSAT-EA is drafting a use and operation manual, which will be published\nshortly and which will indicate in detail some of the characteristics of\nthe satellite and its working modes. Although it is not definitive,\nAmsat-EA is considering some special operating options such as reserving a\nday of the week exclusively for digital communications following the\nexample we know with the AO-92.\n\nFinally, please, remember that, as far as we know, HADES-D is the first\nsatellite with FM repeater service mounted on a pocketqube platform. This\nstandard is the smallest in terms of normalized satellite sizes. HADES-D\nsize is 8x5x5 cm. Its panel surface and battery size are much smaller than\nthe rest of the satellite repeaters in use, so HADES-D is not comparable to\nmost of them either in radiated power or signal strength. HADES-D should be\nconsidered a QRP satellite.\n\n[ANS thanks Félix Páez, EA4GQS, of the HADES-D team, and Drew Glasbrenner,\nKO4MA, AMSAT Vice President - Operations and OSCAR Number Administrator,\nfor the above information]\n\n---------------------------------------------------------------------\n\nClarkSat-1 Deployed from ISS\n\nClarkSat-1 was one of two cubesats deployed from the International Space\nStation (ISS) via the Japanese \"Kibo\" module on Monday, December 18. Also\nknown by the name \"AMBITOUS,\" and by the callsign JS1YLT, the satellite was\ndescribed as follows in frequency coordination applications:\n\nClarkSat-1 is a 1U size satellite, and about 22 students of Clark Memorial\nInternational High School having amateur radio qualification or intending\nto obtain it will be engaged in the development of the satellite, and\noperate it by using the amateur radio band.\n\n+ Optical Camera Mission To take pictures of the Earth and downlink them in\n430 MHz band (GMSK, 4,800 bps). The pictures are to be received at control\nstation and general amateur stations are also expected to receive them and\nreport to us as the downlink schedule will be published on our website and\nsocial media.\n\n+ Digi-talker Mission 40 to 120 seconds long Digi-talker signal (Voice or\nSSTV pictures in Robot 36 format recorded before launch) including the call\nsign and school name will be transmitted from the satellite and be expected\nthat the general amateur stations will receive the signal and report back\nto us.\n\nHigh school students with amateur radio license will be engaged in the\ndevelopment of the satellite, and high school students will operate the\nsatellite. These activities will improve the amateur radio and satellite\ncommunication skills of the students. The project will also serve as a\nmodel case for the development of amateur satellites by the younger\ngeneration, and stimulate the interest of the younger generation in amateur\nradio and satellite communications. The satellite information, such as\norbital position and operation time, will be actively disseminated to the\nworld through the website and social media, so that radio amateurs all over\nthe world will have an opportunity to receive image data and digi-talker\nsignals transmitted from the satellite.\n\nA downlink on 435.130 MHz has been coordinated by the International Amateur\nRadio Union (IARU) for ClarkSat-1. The ClarkSat-1 team requests signal\nreports sent to \"[email protected]\". Satellite status reports will be\nposted on X.com @sat1_AMBITIOUS\n\n[ANS thanks JAXA, Masanobu Tsuji, JA1DAO, and IARU for the above\ninformation]\n\n+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+\n\n Need new satellite antennas?

Amateur radio fared very well\noverall, despite the enormous pressures across the radio spectrum from LF\nto terahertz. This is a tribute to the effort of the International Amateur\nRadio Union (IARU) team, who at times had to work from 8:00 a.m. to as late\nas 2:00 a.m. the next morning, as well as on the weekends.\n\nAt the top of the amateur radio priority list was Agenda Item (AI) 9.1b,\nregarding the coexistence of the secondary amateur and amateur-satellite\nallocation with the primary radionavigation satellite service in the 1240 -\n1300 MHz band. This had seen 4 years of strenuous effort prior to WRC and\nresulted in a recommendation being agreed upon at the Radiocommunication\nAssembly, followed by WRC-23 participants agreeing to mention the\nrecommendation in a new footnote for the allocation. Both the\nrecommendation and the footnote are an excellent outcome for the amateur\nservices.\n\nOther items were relevant to the amateur service and were prioritized\nbeforehand:\n\n AI 1.12: 40 - 50 MHz radar sounders. These are now largely limited to\nthe polar area.\n\n AI 1.14: 231.5 - 252 GHz re-allocations for Earth sensing. Fortunately,\nour secondary 241 - 248 GHz allocation is unchanged, and the primary\nallocation of 248 - 250 GHz is unaffected.\n\n AI 9.1a: Space weather sensors was an item of major interest. A clear\ndefinition for such sensors was confirmed, with frequency protection being\nagreed upon as an agenda item for WRC-27.\n\n AI 1.2: More broadband in the 3.3 GHz and 10 GHz bands (in Region 2).\nThis is a difficult challenge, as the amateur services are secondary with\nnumerous (mainly South American) countries allocating mobile broadband by\nway of footnotes. Instead of a region-wide designation for IMT at 10.0 -\n10.5 GHz in Region 2, there is a footnote limited to a dozen countries.\n\nWRC-23 agreed to an agenda for the next conference under AI 10. This AI had\nan unprecedented number of proposals for WRC-27 and preliminary ones for\nWRC-31. Following the relatively quick agreement on AI 9.1b, the IARU team\nswitched most of its efforts to the following future proposals to reduce\nthe impact on the amateur services, as numerous amateur bands were under\nconsideration.\n\nWRC-27\n\nThe WRC-27 agenda will have 19 items. The following are the most relevant\nto the amateur services:\n\n 1300 - 1350 MHz: A previous proposal for this band, adjacent to 23\ncentimeters, was suppressed, providing certainty for our secondary\nallocation.\n\n Space Weather: This potential AI was initially very concerning, as the\n0.1 - 20 MHz and 28 and 50 MHz bands were initially under consideration,\nuntil concerns were raised, and a team effort resulted in these allocations\nbeing removed from the topic.\n\n Lunar Communications: This future agenda item initially included 70\ncentimeters and other bands where Earth-moon-Earth could be restricted.\nFortunately, the UHF aspect of this AI was modified to exclude 430 - 440\nMHz.\n\n 10 GHz: We were fortunate that this band was withdrawn from another\nround of consideration for mobile broadband, especially in Region 1.\n\nWRC-31\n\nA record number of preliminary item resolutions were agreed on. The\nfollowing two are especially relevant:\n\n Wireless Power Transmission (WPT): Both near-field and beamed are being\nconsidered as part of the International Telecommunication Union radio\nregulations, whilst minimizing the impact from interference.\n\n 275 - 325 GHz Allocations: This will include an opportunity for the\namateur and amateur-satellite service.\n\nThe IARU team worked effectively to minimize the amateur bands from future\nstudies, which is a great result for amateur radio.\n\nIARU is very pleased with the overall result of WRC-23. The IARU team has\nalready started to discuss and consider how to engage and resource for the\nnext cycle leading up to WRC-27. IARU WRC Coordinator and Vice President\nOle Garpestad, LA2RR, expressed his pleasure with the results and\ncomplimented the extraordinary effort of the dedicated team of IARU\nvolunteers who worked long hours to achieve the results that will benefit\nall amateurs.\n\nThe IARU team includes ARRL Technical Relations Specialist Jon Siverling,\nWB3ERA. WRC-23 ran from November 20 – December 15, 2023.\n\n[ANS thanks International Amateur Radio Union Secretary Joel Harrison,\nW5ZN, and ARRL News for the above information]\n\n+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+\n\n Want to fly the colors on your own grid expedition?\n Get your AMSAT car flag and other neat stuff\n from our Zazzle store!\n 25% of the purchase price of each product goes\n towards Keeping Amateur Radio in Space\n https://www.zazzle.com/amsat_gear\n\n+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+\n\nChanges to AMSAT-NA TLE Distribution for Dec. 22\n\nTwo Line Elements or TLEs, often referred to as Keplerian elements or keps\nin the amateur community, are the inputs to the SGP4 standard mathematical\nmodel of spacecraft orbits used by most amateur tracking programs.

The\ndownlink frequency on which to listen is 145.800 MHz worldwide.\n\nNo contacts have been scheduled from 2023-12-21 to 2024-01-14. The complete\nschedule page has been updated as of 2023-12-21 05:00 UTC.\n\nSSTV from the ISS was to be sent on 145.800 MHz using the PD120 format. The\nevent was scheduled for Sat 2023-12-16 at 10:15 UTC through Tue 2023-12-19\naround 18:00 UTC. Unfortunately there is an issue that is still attempting\nto be resolved, so no signals were received. Hopefully the event can be\nrescheduled in the near future. The Service Module radio is temporarily\nstowed.\n\nAs always, if there is an EVA, a docking, or an undocking; the ARISS radios\nare turned off as part of the safety protocol.\n\nThe crossband repeater continues to be active (145.990 MHz up {PL 67} &\n437.800 MHz down), but operation has been interrupted due to undocking\nmaneuvers this past week. If any crewmember is so inclined, all they have\nto do is pick up the microphone, raise the volume up, and talk on the\ncrossband repeater. So give a listen, you just never know.\n\nNote, all times are approximate. It is recommended that you do your own\norbital prediction or start listening about 10 minutes before the listed\ntime.\n\nThe latest information on the operation mode can be found at\nhttps://www.ariss.org/current-status-of-iss-stations.html\n\nThe latest list of frequencies in use can be found at\nhttps://www.ariss.org/contact-the-iss.html\n\n[ANS thanks Charlie Sufana, AJ9N, one of the ARISS operation team mentors\nfor the above information]\n\n--------------------------------------------------------------------\n\nUpcoming Satellite Operations\n\nNone scheduled at this time.\n\n[ANS thanks Ian Parsons, K5ZM, AMSAT rover page manager, for the above\ninformation]\n\n---------------------------------------------------------------------\n\nHamfests, Conventions, Maker Faires, and Other Events\n\nAMSAT Ambassadors provide presentations, demonstrate communicating through\namateur satellites, and host information tables at club meetings, hamfests,\nconventions, maker faires, and other events.\n\n+ ARISS 40th Anniversary Conference: Celebrating the Positive Impact of\nAmateur Radio on Human Spaceflight\nCenter for Space Education, Adjacent to NASA Kennedy Space Center Visitor's\nCenter, Florida, USA\nFebruary 22-24, 2024\n\n[ANS thanks the AMSAT Events page for the above information]\n\n---------------------------------------------------------------------\n\nSatellite Shorts From All Over\n\n+ NASA has released a three minute video retrospective of its\naccomplishments in 2023.

It could take\nseveral weeks for engineers to develop a new plan to remedy the issue.\nLaunched in 1977, the spacecraft and its twin, Voyager 2, are the two\nlongest-operating spacecraft in history [behind AO-7, that is]. In\naddition, commands from mission controllers on Earth take 22.5 hours to\nreach Voyager 1, which is exploring the outer regions of our solar system\nmore than 15 billion miles (24 billion kilometers) from Earth. That means\nthe engineering team has to wait 45 hours to get a response from Voyager 1\nand determine whether a command had the intended outcome.
