    "content": "AMSAT NEWS SERVICE SPECIAL BULLETIN\nANS-321\n\nThe AMSAT News Service bulletins are a free, weekly news and infor-\nmation service of AMSAT North America, The Radio Amateur Satellite\nCorporation. ANS publishes news related to Amateur Radio in Space\nincluding reports on the activities of a worldwide group of Amateur\nRadio operators who share an active interest in designing, building,\nlaunching and communicating through analog and digital Amateur Radio\nsatellites.\n\nThe news feed on http://www.amsat.org publishes news of Amateur\nRadio in Space as soon as our volunteers can post it.\n\nPlease send any amateur satellite news or reports to:\nans-editor at amsat.org.\n\nIn this edition:\n\n* AO-85 Commissioned, Handed Over To AMSAT-NA Operations\n\nSB SAT @ AMSAT $ANS-321.01\nANS-321 AMSAT News Service Weekly Bulletins\n\nAMSAT News Service Bulletin 321.01\n>From AMSAT HQ KENSINGTON, MD.\nNovember 17, 2015\nTo All RADIO AMATEURS\nBID: $ANS-321.01\n\n\nAO-85 Commissioned, Handed Over To AMSAT-NA Operations\n\nAO-85 has been formally commissioned and turned over to AMSAT\nOperations, who are now responsible for the scheduling and modes.\n\nThe following guidelines are provided for users:\n\nUplink power should be on the order of minimum 200 W EIRP for full\nquieting at lower antenna elevation angles. Your mileage may vary.\nWith an Arrow, 5 W has been used successfully to make contacts.\n\nPolarity is important. The satellite antennas are linear. So, if you\nare using linearly polarized antennas, you will need to adjust\nthroughout the pass. Full duplex operation facilitates these\nadjustments while transmitting and is highly recommended.\n\nThe downlink is very strong and should be heard well with almost any\nantenna.\n\nDownlink audio is 5 kHz deviation, as expected. Many will perceive\nthat the audio is \"low.\" This is an effect of the filtering below 300\nHz, which provides for the DUV telemetry, coupled with any noise on\nthe uplink signal resulting from lack of full quieting or being off\nfrequency. That makes for less fidelity than a typical receiver in\nterms of audio frequencies passed.\n\nTransmit (downlink) frequency varies with temperature.  Due to the\nwide range of temperatures we are seeing in the eclipse cycle, the\ntransmitter can be anywhere from around 500 Hz low at 10°C to near 2\nkHz low at 40°C.\n\nReceive frequency has been generally agreed to be about 435.170 MHz,\nalthough the AFC makes that hard to pin down and also helps with the\nuplinks that are off frequency.\n\nProbably the most notable observations about AO-85 are an apparent\nlack of sensitivity and difficulty in turning on the repeater with\nthe 67 Hz CTCSS when it is not yet activated, or holding it on by the\npresence of the CTCSS.  We have determined a probable cause for the\nsensitivity issue and while that can't be fixed on AO-85 we are\ntaking steps to prevent similar issues on the rest of the Fox-1\nCubeSats.  The tone detection threshold along with the receive\nsensitivity issue makes it hard to bring up the repeater.  This is\nbeing addressed by adjusting the values for a valid tone detection in\nthe other Fox-1 CubeSats now that we have on orbit information about\ntemperatures and power budget.  Full details will be in the Nov/Dec\nAMSAT Journal.\n\nIt is important to remember that science is the reason behind the\nFox-1 satellites. Not only does science help with the launch cost, it\nprovides a great amount of educational value both from the science\npayload and in amateur radio itself. The data-under-voice (DUV)\ntelemetry is an excellent way to provide the science without\nsacrificing the use of the satellite for communications, which would\nbe the case if higher speed downlinks were needed. DUV provides\nconstant science as long as the repeater is in use, which in turn\nprovides more downlink data for the science - a mutually beneficial\ncombination.\n\nFox-1A is AMSAT-NA's first CubeSat. Many new techniques are\nincorporated and lessons will be learned, as with any new \"product.\"\nThe Fox-1 Project is a series of CubeSats. A total of five will be\nbuilt and flown. Launches are scheduled for three more, and a new\nNASA CubeSat Launch Initiative proposal will be submitted for the\nfifth. We will incorporate changes from what we learn in each launch,\nto the extent possible, in subsequent Fox-1 CubeSats.\n\nOf the four NASA sponsored CubeSats on the ELaNa XII launch October\n8, we are sad to report that ARC1 was never heard from and BisonSat\nwas lost after a few weeks of operation. AMSAT extends our deepest\nsympathy to the people who worked so hard on these projects. To our\nmembers, we want to say that the Fox Team is very proud and pleased\nthat our first CubeSat is very successful and hopefully will be for\nsome time.\n\n[ANS thanks Jerry NoJY for the above information]\n\n\n---------------------------------------------------------------------\n\n\n/EX\n\nIn addition to regular membership, AMSAT offers membership in the\nPresident's Club.
