ARISS News Release no. 18-06

ARISS NEWS RELEASE no. 18-06 May 10, 2018 David Jordan, AA4KN ARISS PR aa4kn(a)amsat.org ARISS HamVideo Currently Not Transmitting The HamVideo digital Amateur Television (DATV) transmitter aboard the International Space Station (ISS) Columbus module recently ceased transmitting. The unit's indicators show it is functioning but its signal cannot be detected on the ground. The ARISS team's efforts to get the transmitter working again have been unsuccessful, thus far. A series of steps are currently being undertaken to try to diagnose the problem. However, if an actual failure occurred, only a ground-based evaluation will fully diagnose the problem. The ARISS International team is working diligently to bring HamVideo back to full operation as soon as practical. We have started coordination with our space agency partners and with our sponsors to expeditiously troubleshoot the issue on-board and, if necessary, troubleshoot and repair the device on the ground. The HamVideo DATV transmitter has become a very valuable educational asset that astronauts enjoy employing as part of the ARISS connection. Astronauts Tim Peake, KG5BVI; Paolo Nespoli, IZ0JPA; and Thomas Pesquet, FX0ISS, regularly utilized HamTV to inspire students and educators during ARISS contacts scheduled as part of these astronauts' ISS missions. Australian and European HamTV ground stations have been operational for receiving and distributing DATV signals from the ISS, and in the US, HamTV stations are under development. Several hams in Japan have set up ground stations that have received HamVideo. As more information becomes available on the HamVideo status and on any potential repair plans, we will keep you informed through future news releases and via messages on the ARISS web site www.ariss.org. ARISS relies on its sustaining sponsors, along with many devoted individual donors and ARISS volunteers, to support the day-to-day operations and to help with related expenses. These supporters are instrumental in developing and funding the build of our new radio systems. For everyone interested in helping ARISS inspire, engage and educate youth, hams and the public through amateur radio on the ISS, please donate to ARISS at www.amsat.org or www.ariss.org. About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies and amateur radio.

Re: [amsat-bb] NASA Helical Antenna Question
by MICHAEL WILLIAMS 10 May '18

10 May '18

John (vk2fak), You said "Is there any details on the web about this type of helix, have never seen it with a ring reflector in books." I've also never seen a helix ring reflector design in any antenna books. My first home brew helix followed AF9Y's design exactly from his site http://www.af9y.com/helix.htm which used a ring reflector. My second build did not use PVC boom (too heavy) or copper tubing (too expensive) but a 1 in. square metal boom and aluminum clothes line wire. I kept the ring reflector. This is the first time I've seen two reflectors used. It would be interesting to discover who NASA's supplier is for this antenna and see the spec's. Regards, Mike

Hey bird folk, I've been working with Chris, VO1IDX/6Y5IDX to get his logs sorted out. However, some passes may have been lost due to phone issues during rainstorms while he was in Jamaica. The following are in the log at this time, and should be uploaded tomorrow: YS1MS(x2), TI2CDA, TI4DJ, FG8OJ, WP4PRD, N1RCN (x2), KE4AL, K9EO, N1COR, HP2VX, NA2AA(x2), N9EAT, AK4WQ, AA5PK, N8HM, N8RO, K4FEG, KD8ATF, KG4AKV, KB1PVH, NK1K. If you worked them, and have a recording available to prove it, forward them to either me or Chris VO1IDX. His email is good on QRZ. Additionally, forward any lotw issues to either of use. Paper QSL cards are via direct to VO1IDX. 73, Marty N9EAT

Crazy Alaska Grids
by Gabriel Zeifman 09 May '18

09 May '18

Hello fellow bird folk, Tomorrow evening (Wednesday) I embark on a quick rove to the far north. Being that I have a rare two day "weekend" this week, I thought might as well take advantage of it. I will be going to Barrow, AK, the furthest north point in the United States at over 71 degrees north, well into the Arctic. The grid is BQ11. I arrive in Barrow mid-day on Thursday (will be spending the night in Anchorage, as I have activated all nearby grids thoroughly and there is an active sat op in BP51, I have no plans to activate). Shortly after arriving in Barrow, I will get on a Cessna Caravan to Wainwright, AK, a short way southwest of Barrow. The grids here are AQ90 and BQ00 and I plan to be on the line. I only have about four hours on the ground in Wainwright, approximately 2105Z Thursday until 0100Z before returning to Barrow. I will focus on the full NA AO-7 passes as well as FO-29 towards JA and EU, other passes as feasible. Upon return to Barrow, I will have a rental car and be up all through the night working passes #fullharambe until I leave mid-day on Friday with a focus on FO-29. I will bring my ninja FT-817NDs as well as my IC-910H, with trusty Arrow. Two other grids possible are BQ50 and BP64, but these are relatively short stopovers on milkrun flights and I definitely don't expect to be able to activate, although if the opportunity presents itself I shall seize such opportunity to snag the /r. There should be many opportunities for chasers throughout the northern hemisphere to get BQ11 and still decent chance for the others. Specific updates will be posted to twitter @AL6D_Alaska as possible and necessary. 73 harambe, Gabe AL6D/VE6NJH (ex NJ7H)
