    "content": "AMSAT NEWS SERVICE\nANS-295\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* AMSAT Describes RadFxSat/Fox-1B Commissioning Plans\n* CAS-4A and CAS-4B Amateur Radio Linear Transponders Activated\n* Caution Urged in Using High Duty Cycle Digital Modes via Satellite\n* ARISS International Chair Frank Bauer, KA3HDO, Wins G3AAJ Trophy\n* AMSAT-UK YouTube Channel Updated with 2017 Colloquium Recordings\n* Upcoming ARISS Contact Schedule as of 2017-10-19\n* Satellite Shorts From All Over\n\nSB SAT @ AMSAT $ANS-295.01\nANS-295 AMSAT News Service Weekly Bulletins\n\nAMSAT News Service Bulletin 295.01\n  From AMSAT HQ KENSINGTON, MD.\nDATE October 22, 2017\nTo All RADIO AMATEURS\nBID: $ANS-295.01\n\nAMSAT Describes RadFxSat/Fox-1B Commissioning Plans\n\nAMSAT Vice-President Engineering, Jerry Buxton, NØJY wrote what to\ninitially expect when the AMSAT RadFxSat/Fox-1B cubesat is launched\nas a passenger on NASA's ELaNa XIV mission on Friday, Nov. 10, from\nVandenberg Air Force Base, California.\n\nLiftoff will be aboard a United Launch Alliance Delta II rocket from\nSpace Launch Complex 2 and is targeted for 1:47 a.m. PT (4:47 a.m. ET,\n9:47 am UTC) at the opening of a 65-second launch window. Launch cov-\nerage will begin on NASA Television and the agency’s website at\n1:15 a.m. PT.\n\nRadFxSat/Fox-1B will automatically come up in Beacon Mode, transmitting\na beacon and voice ID (Veronica saying \"RadFxSat Safe Mode\") every two\nminutes, starting about 50 minutes after deployment. The AMSAT command\nstations will want to see voltage and current data to determine that\nit's healthy and conduct various tests before opening it up for general\nuse.\n\nTelemetry makes the engineering and operations teams very happy,\nstarting ASAP after startup (~55 minutes after deployment) and for\nthe next 72-96 hours at least as we look for successful startup, watch\nthe general health and function as the satellite begins to acclimate\nto space, and perform the on orbit checkout. Ground stations are also\ninvited to continue uploading received telemetry for the life of the\nsatellite.\n\nIf you are capturing telemetry with FoxTelem please be sure that \"Upload\nto Server\" is checked in your settings, and your Ground Station Params\nare filled in as well. You can help AMSAT and everyone waiting to get\non the air with RadFxSat tremendously, by capturing RadFxSat telemetry.\n\nIn the initial Beacon Mode, the transmitter is limited to 10 seconds on\ntime then does the two minutes off cycle as Paul pointed out. For those\nof you capturing telemetry, that means that you will only see Current\nframes and no High or Low frames because the High and Low are truncated\nas it takes just over 10 seconds to send two frames. Veronica may also\nbe cut off before she gets to say her whole ID string. If Veronica is\nspeaking, \"RadFxSat Fox-1B Safe Mode\" which is the full ID, if it's cut\noff then we're still in Beacon Mode. If we are seeing good data from\nuser telemetry data, it is likely when it comes over the U.S. for the\nfirst good pass we will command it from Beacon Mode to normal Safe Mode,\nwhich then puts RadFxSat in full (still Safe Mode though) operation and\ntransmits a full two frames of telemetry which is one Current frame\nfollowed by, and alternating each ID cycle, a High or a Low frame.\nVeronica now has time to make the whole ID announcement, in Safe Mode.\n\nYOUR HELP IS NEEDED!\n--------------------\nJerry, NØJY commented further ...\n\nHelp your friends and all of our satellite ham friends get on the air\nand have fun sooner by being polite and patient!\n\nThe on orbit checkout procedure is similar to Fox-1A/AO-85 and could\nbe completed in as little as a few days if we have the cooperation of\nthe users. It is very important, not to mention just plain good Amateur\nOperating Practice, to refrain from using the transponder uplink so we\ncan do the on orbit tests, including when we turn on transponder mode\nfor testing. I can't stress enough, the importance of this cooperation\nnot just for us but for all users, simply having a little patience so\nwe can conduct the tests as quickly and accurately as possible.\n\nAMSAT will make it broadly known when the tests are complete and the\ntransponder is available for all to use. If you hear someone on the\ntransponder, please don't assume that it is open for general use -\ncheck the AMSAT website, Facebook, Twitter, to be sure you're not\naccidentally jumping in with and unwittingly interfering with the\ncommissioning process.\n\nLots of hams put thousands of volunteer hours of their time into making\nRadFxSat happen. Just like any ham radio project you might undertake,\nwe build satellites. We do it because we like to, and when we're done\nwe freely share our project with hams everywhere as is the spirit of\namateur radio.\n\nI am asking all satellite hams to contribute just a little bit of your\ntime to the fun now, by being patient and just gathering telemetry,\nnot using the transponder uplink, and helping us complete the last few\ndays of getting RadFxSat in orbit and operating for all of you.\n\nThank you very much, see you on the bird!\n\n[ANS thanks AMSAT Vice-President Engineering, Jerry Buxton, NØJY, for the\n   above information]\n\n\n---------------------------------------------------------------------\n\n\nCAS-4A and CAS-4B Amateur Radio Linear Transponders Activated\n\nOn Wednesday, October 18, 2017 the amateur radio linear (SSB/CW) \ntransponders on\nthe CAS-4A and CAS-4B satellites were activated.\n\nCAMSAT’s amateur radio payloads piggybacked on the optical remote \nsensing micro-\nsatellites ZHUHAI-1 01 (OVS-1A / CAS-4A) and ZHUHAI-1 02 (OVS-1B / \nCAS-4B) that\nwere launched at 0300 GMT on Thursday, June 15, 2017 from the Jiuquan \nSatellite\nLaunch Center, on the CZ-4B launch vehicle. The primary payload of the \nlaunch\nwas a hard X-ray modulation telescope satellite (HXMT).\n\nCAS-4A Amateur Radio Payload:\n  Call sign: BJ1SK\n  VHF Antenna: one 1/4? monopole antenna with max. 0 dBi gain located at \n+Z side\n  UHF Antenna: one 1/4? monopole antenna with max. 0 dBi gain located at \n-Z side\n  CW Telemetry Beacon: 145.855 MHz 17 dBm\n  AX.25 4.8k Baud GMSK Telemetry: 145.835 MHz 20 dBm\n  U/V Linear Transponder Downlink: 145.870 MHz 20 dBm, 20 kHz bandwidth, \nInverted\n  U/V Linear Transponder Uplink: 435.220 MHz\n\nCAS-4B Amateur Radio Payload:\n  Call sign: BJ1SL\n  VHF Antenna: one 1/4? monopole antenna with max. 0 dBi gain located at \n+Z side\n  UHF Antenna: one 1/4? monopole antenna with max. 0 dBi gain located at \n-Z side\n  CW Telemetry Beacon: 145.910 MHz 17 dBm\n  AX.25 4.8k Baud GMSK Telemetry: 145.890 MHz 20 dBm\n  U/V Linear Transponder Downlink: 145.925 MHz 20 dBm, 20 kHz bandwidth, \nInverted\n  U/V Linear Transponder Uplink: 435.280 MHz\n\n[ANS thanks Alan, BD1DU, for the above information]\n\n\n---------------------------------------------------------------------\n\n\nCaution Urged in Using High Duty Cycle Digital Modes via Satellite\n\nA report in ANS-288 discussed an experiment operating with the\nWSJT-X FT8 via satellite. Satellite operators have gained more\nexperience with this mode over this past week.\n\nAs a result of on-the-air observation other satellite users\nplanning to try FT8 or MSK144 modes via satellite are encouraged\nuse caution using these modes and possibly avoid their use\ncompletely in light of problems.\n\nDave, KG5CCI wrote, \"He noticed a very hard time getting into the\ntransponder. The pass was nearly overhead, and the 3w-4w that is\nnormally sufficient was barely cutting it. I also noticed it was\n'up and down' alot, whereas some moments it was easy to get in,\nthen it would be nearly impossible. There were also pockets of\n'noise' all over the transponder, that sounded somewhat digital,\nbut I just couldn't place them.\" Further investigation revealed\nthat an MSK144 signal in the transponder passband was causing the\nproblems.\n\nMatthew, NJ4Y noted, \"Experimentation isn’t the problem, too much\npower is. It’s bad enough on SSB, worse with CW, and killer on\nconstant duty cycle modes like FT8.\"\n\nTo gain a full understanding of the situation readers are encouraged\nto follow the amsat-bb message thread which can be accessed at:\nhttp://www.amsat.org/pipermail/amsat-bb/2017-October/064896.html\n\n[ANS acknowledges the comments submitted via amsat-bb from W5RKN,\n  KG5CCI, KB1PVH, W5PFG, and others]\n\n\n---------------------------------------------------------------------\n\n\nARISS International Chair Frank Bauer, KA3HDO, Wins G3AAJ Trophy\n\nARISS International Chair Frank Bauer, KA3HDO, has been honored with the Ron\nBroadbent, G3AAJ, Trophy. The presentation came during the AMSAT-UK\nInternational Space Colloquium this past weekend.\n\n“AMSAT-UK totally shocked me yesterday at the colloquium with the Ron \nBroadbent\nTrophy,” Bauer reacted. “I was nearly speechless when asked to come up and\nreceive the trophy for ARISS work. I mentioned that, early on, Ron was a\nphenomenal supporter and contributor to ARISS, with his sage advice and\nguidance.”\n\nThe G3AAJ trophy is awarded annually by AMSAT-UK to an individual or \ngroup for\noutstanding service to the Amateur Satellite service. The trophy was \ndonated to\nAMSAT-UK by the late Ron Broadbent, G3AAJ.\n\nARISS received the G3AAJ trophy last year in recognition of the ARISS UK \nteam’s\ndedication in working with the UK Space Agency to facilitate the Principia\nMission of astronaut Tim Peake, KG5BVI, aimed at engaging students in 10 UK\nschools in science, technology, engineering, and mathematics (STEM) \nsubjects.\n\n[ANS thanks ARRL for the above information]\n\n\n---------------------------------------------------------------------\n\n\nAMSAT-UK YouTube Channel Updated with 2017 Colloquium Recordings\n\nAMSAT-UK has begun uploading recordings of all talks from the 2017 \nColloquium,\nOctober 14-15 to the AMSAT-UK YouTube Channel:\nhttps://www.youtube.com/user/AMSATUK\n\nSome of the videos have already been uploaded; refresh your screen\noccasionally to to catch additional 2017 Colloquium uploads.\n\n2017: An introduction to Amateur satellites - David Johnson, G4DPZ and \nCarlos\nEavis G3VHF\nhttps://www.youtube.com/watch?v=1Tj2rUsNpPs&t=1039s\n\n2017: Es'hail-2 Geostationary Amateur Satellite - Peter Guelzow DB2OS \n(AMSAT-DL)\nhttps://www.youtube.com/watch?v=L67pza0hCZw\n\n2017: The Goonhilly project (aka playing with big boys toys) - Noel Matthews\nG8GTZ\nhttps://www.youtube.com/watch?v=xzrcLFFEq74\n\n[ANS thanks AMSAT-UK for the above information]\n\n\n---------------------------------------------------------------------\n\n\nUpcoming ARISS Contact Schedule as of 2017-10-19\n\nChiddix Junior High School,  Normal, IL, direct via W9AM\nThe ISS callsign is presently scheduled to be  NA1SS\nThe scheduled astronaut is Joe Acaba KE5DAR (***)\nContact is a go  for: Mon 2017-10-23 15:31:15 UTC 27 deg (***)\n\nBeaconsfield State  School, Mackay, Queensland, Australia, telebridge via\nIK1SLD (***)\nThe ISS  callsign is presently scheduled to be IRØISS (***)\nThe scheduled astronaut  is Paolo Nespoli IZØJPA (***)\nContact is a go for: Thu 2017-10-26 08:23:02  UTC 40 deg (***)\n\nGlanmire Community College, Cork, Ireland, direct  via EI5CRC and Colegiul\nNational Calistrat Hogas Piatra Neamt, Piatra Neamt, Romania, telebridge\nvia EI5CRC\nThe ISS callsign is presently scheduled to be  OR4ISS\nThe scheduled astronaut is Joe Acaba KE5DAR (***)\nContact is a go  for: Thu 2017-10-26 09:55:45 UTC 68 deg (***)\n\nIstituto Tecnico  Tecnologico “Enzo Ferrari”, Borgo A Mozzano, Italy and\nLiceo Statale “G.
