So far I've restarted the bird three times, and each\ntime it appears to stay up for a day or more. We can expect the\nsituation to worsen, as the eclipse periods get longer and the\nsatellite temperatures continue to go down. We've been warning you,\nget those AO-16 contacts in now!\"\n\nMark says he will try to restart AO-16 as long as possible when\nhis schedule allows him. Satellite operator reports to the OSCAR\nSatellite Status page by KD5QGR at http://oscar.dcarr.org/ are\nvery helpful.\n\nMark continues, \"If the birds is operational in voice mode, you\nshould clearly hear the \"not-so-repressed carrier\" on the downlink.\nI have a special request - if you do not hear the carrier, please do\nnot transmit to AO-16, as your transmissions make it difficult to\ncommand the satellite. And, if you hear the \"hummmming\" of the PSK\ntransmitting, again please do not attempt to transmit to the bird;\nit's likely that I have restarted the bird and need to collect tele-\nmetry before configuring it into voice mode.

Early in the week several amateur stations around the world\nwere able to copy the slow-scan television (SSTV) pictures trans-\nmitted from the ISS. On Friday, December 5 the ARISS crossband\nFM repeater was enabled with several stations reporting excellent\nsignals. When the crossband repeater is operational its uplink is\non 437.800 MHz FM with its downlink on 145.800 MHz FM. Remember to\nadjust for doppler shift when operating in this mode.\n\nFor the week of December 7-12 ARISS will run a test of 9600 baud\npacket operations on the simplex frequency 145.825 MHz.\n\nTo celebrate our 25 years of amateur radio operations from space,\nthe ARISS team has planned a set of special event opportunities\nduring the month of December and part of January. A special certi-\nficate is being developed for those who communicate with the ISS,\neither 2-way direct (with the ISS crew,the digipeater, or cross\nband repeater), or 1-way reception of SSTV or voice downlink. Several\n\"surprises\" planned over the month-long celebration. The surprises\nwill be announced once ARISS is pre-positioned to accomplish them.\n\nARISS reminds everyone that ISS flight requirements related to EVA\nand vehicle activity may require the radio to be off for some portion\nof this schedule. And school contacts and general QSO opportunities\nby the crew will also preempt this schedule for short periods of time.\nBut remember that if you hear these, you still qualify for a commemor-\native certificate.\n\n[ANS thanks Frank, KA3HDO, AMSAT-NA V.P. for Human Spaceflight Programs\n and ARISS International Chairman for the above information]\n\n/EX\n\n\nSB SAT @ AMSAT $ANS-342.03\nSumbandilasat to be Launch from Baikonur\n\nAMSAT News Service Bulletin 342.03\n From AMSAT HQ SILVER SPRING, MD.\nDecember 7, 2008\nTo All RADIO AMATEURS\nBID: $ANS-342.03\n\nIt is official! South Africa's second satellite, SumbandilaSat, will \nbe launched\nfrom the Russian Baikonur Cosmodrome in the December to March time frame.\n\nSumbandilaSat has been unpacked and is undergoing testing at SunSpace in\nStellenbosch before it will be shipped to Russia for integration with \nthe launch\nvehicle. Engineers at the launch site are preparing a special adapter ring to\naccommodate the Sumbandila structure on the rocket.\n\n\"Sumbandila\" means showing or pointing the way. Freely translated into English\n\"Pathfinder\"\n\nThe Amateur Radio Payload will be operating in conjunction with the University\nof Stellenbosch Software Defined Receiver project as it will share the VHF\nreceiver and UHF transmitter used by the SDR project.\n\nSA AMSAT has designed and built a control system to facilitate the following\noperations:\n\n * V/U voice transponder with an uplink in the 2 metre band and a \ndownlink in\n the 70cm band.\n\n * A parrot repeater (voice digipeater)\n\n * A voice beacon\n\nThe control unit will command the various function of the transponder \nand handle\nthe parrot and beacon messaging. On receipt of a tone from the VUCU VHF\nreceiver, the CTCSS tone will be decoded and depending on the tone received the\nunit will command the VU transponder operation or the parrot repeater. In the\ntransponder mode the satellite will act like a cross-band FM repeater and allow\ntwo way communications with other stations on the ground.\n\nIf the tone received indicates parrot operation, the interface unit will record\n20 seconds of audio on its VHF uplink receiver and replay the recorded audio on\nthe UHF downlink.\n\nShould, for a predetermined period, there be no tones received, the controller\nwill initiate a voice beacon, transmitting a pre-recorded message at regular\nintervals. This facility will offer many opportunities for educational\nprojects.\n\n[ANS thanks SA AMSAT for the above information]\n\n/EX\n\n\nSB SAT @ AMSAT $ANS-342.04\nARISS Status - 01 December 2008\n\nAMSAT News Service Bulletin 342.04\n From AMSAT HQ SILVER SPRING, MD.\nDecember 7, 2008\nTo All RADIO AMATEURS\nBID: $ANS-342.04\n\n1. Upcoming School Contacts\n\nAn Amateur Radio on the International Space Station (ARISS) contact has been\nscheduled with Ellis School in Belleville, Illinois on Monday, December 8 at\n16:54 UTC. Space studies have been integrated into the school curriculum.\nStudents have created solar system models, written reports and given\npresentations to their classes. They have designed rockets and given talks to\nthe class about where the rockets will go and what they will do in space. They\nhave planned space colonies and determined how the astronauts will travel, how\nthey will obtain food and where they will live. They have also sampled space\nfood. Students have learned about Expedition 18, the Space Shuttle, the\ninternational partners and the ISS and amateur radio. The class is currently\ngrowing seeds that were flown in space.\n\nAn Amateur Radio on the International Space Station (ARISS) contact has been\nscheduled for Stephen F. Austin Elementary School in Richmond, Texas \non Tuesday,\nDecember 9 at 15:43 UTC. Students have studied space and the identifying\ncharacteristics of objects in our solar system including the sun, planets, and\nmoon. Each year the 5th grade students participate in a simulated space shuttle\nmission, performing tasks that would happen on a regular shuttle flight. Each\ngrade level is involved in some manner with the various missions that occur\nthroughout the day. The school has integrated the ARISS contact as part of this\nactivity.\n\nThe Istituto Comprensivo \"Marco Polo,\" in Grado, Italy has been \nscheduled for an\nAmateur Radio on the International Space Station (ARISS) contact on Wednesday,\nDecember 10 at 10:08 UTC.\n\nAn Amateur Radio on the International Space Station (ARISS) contact has been\nscheduled with 2 Circolo Didattico San Giuseppe in Mola di Bari, Bari, Italy on\nFriday, December 12 at 14:14 UTC. Lesson plans have been developed \nfor students\nthat cover amateur radio and space missions. Newspapers, radio and television,\nboth local and regional, will report on the event.\n\n\n2. New Zealand Homeschoolers Experience ARISS Contact\n\nWairarapa Home School Association students from Carterton, Wairarapa, New\nZealand participated in an Amateur Radio on the International Space Station\n(ARISS) contact on Wednesday, November 26 via telebridge stations VK5ZAI and\nVK4KHZ, both in Australia. Mike Fincke, KE5AIT, answered all 15 questions\nasked. The audio was available on EchoLink and Internet Radio Linking Project\n(IRLP). This was the second ARISS contact performed with New Zealand students.\n\n\n3. Video of ARISS - International Education Week Contact\n\nStudents from Poolesville, Maryland, Raleigh, North Carolina and Quito, Ecuador\nexperienced a joint Amateur Radio on the International Space Station (ARISS)\ncontact on Friday, November 14 as part of International Education Week (IEW).\nA video of the participating students from North Carolina and Ecuador has been\nposted to YouTube.

CQ VHF Article on ARISS Meetings\n\nAmateur Radio on the International Space Station (ARISS) member Keith Pugh,\nW5IU, wrote an article for the Fall 2008 issue of CQ VHF which \ncovered the ARISS\nmeetings held in Moscow during July 2008. An excerpt from the article may be\nviewed here: http://www.cq-vhf.com/Fall08Sat.html\n\n\n5. ARISS Commemorative Event\n\nTwenty-five years ago, Owen Garriott, W5LFL, became the first amateur radio\noperator to talk to hams from space on the STS-9 Space Shuttle Columbia mission\nwhich was launched on November 28 and landed on December 8, 1983. To celebrate\nthis event, an Amateur Radio on the International Space Station (ARISS)\ncommemorative event will be held during the month of December through early\nJanuary. A special certificate is being developed for those who communicate\nwith the ISS, either 2-way direct (with the ISS crew, the digipeater, or cross\nband repeater), or 1-way reception of SSTV or voice downlink.
