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 Field Day on the Satellites\n* CAMSAT Details on Three Satellites and an HF Transponder\n* 3A Monaco Activation on FM Satellites in July\n* ARISS Ham Video Transmitter Aboard ISS Defective\n* Call for Volunteers, ANS Seeks Rotating Editors\n\nSB SAT @ AMSAT $ANS-168.01\nANS-168 AMSAT News Service Weekly Bulletins\n\nAMSAT News Service Bulletin 168.01\n From AMSAT HQ KENSINGTON, MD.\nDATE June 17, 2018\nTo All RADIO AMATEURS\nBID: $ANS-168.01\n\n\nAMSAT Field Day on the Satellites\n\nIt’s that time of year again; summer and Field Day! Each year the\nAmerican Radio Relay League (ARRL) sponsors Field Day as a “picnic,\na campout, practice for emergencies, an informal contest and, most\nof all, FUN!”\n\nThe event takes place during a 23-hour period on the fourth weekend\nof June. For 2018 the event takes place during a 27-hour period from\n1800 UTC on Saturday, June 23, 2018 through 2100 UTC on Sunday,\nJune 24, 2018.\n\nThose who set up prior to 1800 UTC on June 23 can operate only 24\nhours. The Radio Amateur Satellite Corporation (AMSAT) promotes\nits own version of Field Day for operation via the amateur sat-\nellites, held concurrently with the ARRL event.\n\nThis year should be easier than many years since we have more than\n10 transponders and repeaters available. Users should check the\nAMSAT status page at http://www.amsat.org/status/ and the pages\nat http://www.amsat.org/?page_id=177 for what is available in\nthe weeks leading up to field day.\n\nTo reduce the amount of time to research each satellite, see the\ncurrent FM satellite table at http://www.amsat.org/?page_id=5012\nand the current linear satellite table at\nhttp://www.amsat.org/?page_id=5033\n\nIf you are considering ONLY the FM voice satellites, there are\nSO-50, AO-85, AO-91, and AO-92. It might be easier this year to\nmake that one FM contact for the ARRL bonus points with so many\nFM birds. The congestion on FM LEO satellites is always so intense\nthat we must continue to limit their use to one-QSO-per-FM-satellite.\nThis includes the International Space Station. You will be allowed\none QSO if the ISS is operating Voice.\n\nAO-92 may be in L/v for the first part of the event, depending on\ncommand station availability. Keep an eye on @AMSAT on Twitter for\nexpected L/v mode change times.\n\nThe full set of rules are posted at:\nhttps://www.amsat.org/field-day/\n\n[ANS thanks AMSAT Director Contests and Awards, Bruce Paige, KK5DO,\n for the above information]\n\n---------------------------------------------------------------------\n\nCAMSAT Details on Three Satellites and an HF Transponder\n\nCAMSAT, China’s Amateur Radio Satellite organization, has offered\nadditional details about the three Amateur Radio satellites it\nplans to launch later this year. Two of the satellites, designated\nCAS-5A and CAS-6, will carry transponders, and one of them will\noffer HF capability. CAMSAT’s Alan Kung, BA1DU, told ARRL that\nthe 6U CAS-5A will carry two HF transponders and two V/UHF trans-\nponders. The plentiful equipment package includes an H/T (21/29 MHz)\nmode linear transponder, an H/U (21/435 MHz) mode linear transponder,\n an HF CW telemetry beacon, a V/U linear transponder, a V/U FM trans-\n ponder, a UHF CW telemetry beacon, and UHF AX.25 4.8k/9.6k baud GMSK\n telemetry.\n\n+ The H/T mode linear transponder will have a 30 kHz wide uplink centered\n on 21.400 MHz, and a downlink centered on 29.490 MHz. RF output is \n0.5 W.\n\n+ An HF CW telemetry beacon will transmit on 29.465 MHz with 0.1 W.\n\n+ The H/U mode linear transponder will have a 15 kHz wide uplink centered\n on 21.435 MHz, and a downlink centered on 435.505 MHz. The RF output is\n 0.5 W.\n\n+ The V/U mode linear transponder will have a 30 kHz wide uplink at\n 145.820 MHz, and a downlink at 435.540 MHz. The RF output is 0.5 W.\n\n+ The V/U mode FM transponder will uplink at 145.925 MHz, and downlink\n at 435.600 MHz. The transponder passband is 15 kHz, and the RF output\n is 0.5 W.\n\n+ The UHF CW telemetry beacon will transmit on 435.570 MHz, with an RF\n output of 0.1 W.\n\n+ UHF AX.25 4.8k/9.6k baud GMSK telemetry will transmit on 435.650 MHz\n at 0.5 W.\n\nKung told ARRL that the HF, VHF, and UHF antennas are quarter-wave\nmonopoles.\n\nA satellite within a satellite, the tiny CAS-5B, weighing 0.5 kilogram,\nwill be deployed from CAS-5A in orbit. It will carry a UHF CW beacon on\nan Amateur Radio frequency. Both CAS-5A and CAS-5B will be placed into\n539 × 533 kilometer, 97.5° orbits. They will launch from the Jiuquan\nSatellite Launch Center in late September.\n\nThe 50-kilogram CAS-6 microsat will include a VHF CW telemetry beacon,\na U/V mode 20 kHz linear Amateur Radio transponder, and AX.25 4.8k baud\nGMSK telemetry. It will also carry an atmospheric wind detector and\nother systems that will operate on non-amateur frequencies.\n\nA launch at sea on an as-yet undetermined date is planned for CAS-6\nfrom the China Academy of Launch Vehicle Technology. The microsat will\nbe placed into a 579 × 579 kilometer, 45° orbit.\n\n[ANS thanks ARRL for the above information]\n\n\n---------------------------------------------------------------------\n\n\n3A Monaco Activation on FM Satellites in July\n\nF4DXV plans FM satellite operation from 3A Monaco (JN33) on\nMonday 02 July ~08:30z to 13z only during a quick break from\nhis trip to Italy. Jerome says, \"Due to a bad horizon (mountains,\nbuildings), I could be only QRV for EU on high FM orbits.\"\n\n[ANS thanks Daily DX for the above information]\n\n\n---------------------------------------------------------------------\n\nARISS Ham Video Transmitter Aboard ISS Defective\n\nGaston Bertels, ON4WF has provided an update regarding the condition\nof the ARISS HamTV system aboard the ISS.\n\nIn mid-April, the Ham Video transmitter on board the Columbus module\nof the ISS stopped working. Extensive testing was performed by the\ncrew on June 1, 2018 which comprised connecting the transmitter to\nthe second ARISS L/S-band patch antenna on the nadir of Columbus.\nThe test was negative. Ground stations did not receive any signal\nfrom Ham Video.\n\nSince on-board repair is impossible ARISS is planning to return the\ntransmitter to Earth. Bertels wrote, \"We hope this plan will be accepted\nby the space agencies and the cost of operations funded by sponsors.\nSchools and crew members performing educational ARISS school contacts are\ndelighted to use Ham Video. We will do the best we can to restart this\nservice as soon as possible. We will keep you informed on progress.\"\n\nAdditional information about the HamTV project can be found on-line at:\nhttps://www.amsat-on.be/\n\n[ANS thanks Gaston Bertels, ON4WF and ARISS HamTV for the above \ninformation]\n\n\n\n---------------------------------------------------------------------\n\n\nCall for Volunteers, ANS Seeks Rotating Editors\n\nThe AMSAT News Service (ANS) is seeking volunteers to serve as\nrotating editors for its weekly newsletter.\n\nEditors work on a rotating schedule, each taking a different turn\nediting a specific week's newsletter as scheduled by the ANS Editor\nin Chief.
