Stations\nin North America may be able to directly hear the ISS downlink on\n145.800 MHz.\n\nThe contact will be available on EchoLink AMSAT conference server \nand IRLP Discovery Reflector 9010. The contact will be webcast on:\nhttp://www.cittadellamediterraneadellascienza.it/\n\nARISS is an international educational outreach program partnering \nthe participating space agencies, NASA, Russian Space Agency, ESA, \nCNES, JAXA, and CSA, with the AMSAT and IARU organizations from \nparticipating countries.\n\nARISS offers an opportunity for students to experience the excitement \nof Amateur Radio by talking directly with crewmembers onboard the \nInternational Space Station. Teachers, parents and communities see, \nfirst hand, how Amateur Radio and crewmembers on ISS can energize \nyoungsters' interest in science, technology and learning.\n\n[ANS thanks ARISS Chairman Gaston Bertels, ON4WF and the SouthGate\n ARC news for the above information]\n\n/EX\n\n\nSB SAT @ AMSAT $ANS-276.05\nOSCAR-11 Signals Heard\n\nAMSAT News Service Bulletin 276.05\n  From AMSAT HQ SILVER SPRING, MD.\nOctober 3, 2010\nTo All RADIO AMATEURS\nBID: $ANS-276.05\n\nOSCAR-11 Signals Heard\n\nClive G3CWV reported that OSCAR-11 was heard by JA0CAW on August 29\nafter being silent since March 30, 2010. Since August 29 it contin-\nued to be heard until September 8 and then again September 18-29. \nExcellent signals have been reported from stations located around \nthe world, and good copy obtained from decoded telemetry frames.\n\nThere has been a significant change since the previous\nperiod of activity which ended in March 2010.  The on-board\nclock is now very stable.  It's gained only three seconds in\n30 days. This is comparable with its accuracy when the\nsatellite was fully operational. During its first 21 years\nit gained approximately one minute per year. However, there\nis still an accumulated loss of 309 days, which has occurred\nduring eclipses of the last few years!\n\nThe other change is that it's now transmitting during\neclipses, although signals are weaker at those times. This\nindicates that there is still some capacity remaining in the\nbattery.\n\nThese two changes suggest that some part of the system may\nhave recently failed 'open circuit' thus reducing the\noverall power drain of the system, and allowing more power\nto be available during eclipses.  There was an unexplained\ncurrent drain observed when analogue telemetry was last\ntransmitted. This fault might have cleared. Interestingly,\nthe status telemetry shows that the Digital Store & Readout\nexperiment has switched off, since the satellite was\npreviously heard in February.\n\nThe satellite appears to be operating for ten days on,\nfollowed by ten days off, so it should start transmitting\nagain around October 9, 2010.\n\nListen for OSCAR-11's VHF AFSK FM  ASCII Telemetry beacon\non 145.826 MHz.\n\nReception reports have been received from Bernard FY1LE,\nRoland DG1EBR, Mike DK3WN, Tetsu JA0CAW, Adam SQ8MFC,\nMM0DNX, Tony VK3KKP/G8HIM, Martin DC1MAR, John M0BIC,\nEtienne F1GRR and Carlos KD6GRF. Many thanks to everyone.\n\nMany reports have also been added to the live satellite\nstatus page, on the website set up by David KD5QGR and Bob\nWB4APR. This is a very convenient and easy to use facility,\nwhich shows the current status of all the amateur satellites. \nStrongly recommended for future reports! The URL is \nhttp://oscar.dcarr.org/index.php\n\nFor the benefit of new listeners, here is a short history\nof OSCAR-11. It was lauched in 1984, providing telemetry\nand other digital services for amateur radio and educational\nusers. During its many years of operation it survived long\nperiods of eclipses and continuous full sunlight.\n\nIn 2002 the satellite reverted to its default mode of\noperation, controlled by the watchdog timer. In 2005 all the\nanalogue telemetry channels failed. Solar eclipses also\nstarted to cause the watchdog timer cycle to reset, which\nswitched off the satellite for approximately 15 days.\n\nIn 2008 solar eclipses became a permanent feature of every\norbit, causing the satellite to switch off for about 15\ndays, probably after only one orbit of transmission. Thus\nthe satellite was not expected to be heard again for any\ncontinuous period until 2019, when there will be some\neclipse free periods. However, the satellite started\ntransmissions unexpectedly in November 2008. These continued\nuntil March, when it was followed by silence until until the\nrecent period of activity.\n\nClive's webpage at www.g3cwv.co.uk contains sound files of\nthe satellite's beacon, archived news and telemetry, and\ninformation about using soundcard and hardware demodulators\nfor data capture. There is also software for capturing data, \nand decoding ASCII telemetry.\n\n[ANS thanks Clive G3CWV for the above information]\n\n/EX\n\nSB SAT @ AMSAT $ANS-276.06\nAO-51 Resumes Operation\n\nAMSAT News Service Bulletin 276.06\n  From AMSAT HQ SILVER SPRING, MD.\nOctober 3, 2010\nTo All RADIO AMATEURS\nBID: $ANS-276.06\n\nAO-51 Resumes Operation\n\nAfter a software crash on September 26 aboard AO-51 took the satellite\noff the air Ground Station Mark Hammond, N8MH reported that as of\nSeptember 29, \"The reloading of AO-51 is essentially complete; the bird \nis in good order.\"\n\nThe AO-51 Command Team configured the satellite for simultaneous opera-\ntion of both the S-band and U-band transmitters. The tradeoff is that \nU-band will be low in power-around 250 mW or so. Also, please notice \nthe use of the 145.880 MHz uplink!\n\nSeptember 29\nFM Repeater, V/S-U\nUplink: 145.880 MHz FM (no PL tone)\nDownlinks: 2401.200 MHz FM *and* 435.300 MHz FM (at low power!)\n\nMark said, \"This is a great time to work on improving the sensitivity \nof your receiver setups! The 250 mW will challenge some of you for sure.  \nPLEASE be sure to follow the \"if you can't hear it, don't try to uplink\" \nbasic rule of satellite operation.\" \n\nIf the satellite supports the dual downlink mode OK, controllers may \nextend the V/S-U mode a few days past the original mode schedule in \norder to give mode S operators a fair shake at some operations and \ntesting--while at the same time allowing some low power mode V/U \noperations.\n\nCheck the Command Team and Operations Group AO-51 News web page for the\nlatest September 2010 AO-51 Schedule: \nhttp://www.amsat.org/amsat-new/echo/CTNews.php\n\n[ANS thanks Mark Hammond N8MH for the above information]\n\n/EX\n\n\nSB SAT @ AMSAT $ANS-276.07\nARISS Status - 27 September 2010\n\nAMSAT News Service Bulletin 276.07\n  From AMSAT HQ SILVER SPRING, MD.\nOctober 3, 2010\nTo All RADIO AMATEURS\nBID: $ANS-276.07\n\nAmateur Radio on the International Space Station (ARISS) Status Report\nSeptember 27, 2010\n\n1.\tSchool Contact\n\nEnglish Estates Elementary School in Fern Park, Florida had a scheduled \ncontact on Thursday, September 30 at 18:00 UTC.
