ARISS News Release No. 18-07

ARISS NEWS RELEASE no. 18-07 May 16, 2018 David Jordan, AA4KN ARISS PR aa4kn(a)amsat.org Hamvention and ARISS Work Together The Amateur Radio on the International Space Station team (ARISS) is happy to announce that Hamvention and ARISS are working together again this year. Hamvention's 2018 theme is, "Amateur Radio.Serving the Community." ARISS serves communities by inspiring great numbers of youth to explore STEM and Amateur Radio. ARISS is kicking off its 2018 fund-raising campaign at Hamvention to raise money for the expensive space-rated parts needed to finish building the required multiple units of the custom-built Multi-Voltage Power Supply, and to help defray some costs of continuing ARISS operations. The power supply is part of the next gen ARISS Interoperable Radio System to replace the intermittent, aging ISS amateur radio station. ARISS Chair Frank Bauer, KA3HDO, said, "Having Hamvention partner with ARISS really puts our 2018 funding campaign into gear." Hamvention's support began with a post on the convention's front web page. The posting discussed teaming up with ARISS, and announcing a special ARISS prize drawing at the convention, and the need for hams to contribute to ARISS right now by going to http://www.ariss.org/donate.html or stopping at the ARISS Hamvention booth. The double boost to ARISS by Hamvention is the featuring of the ARISS Challenge Coin at a special drawing just minutes before the convention's big prize drawings on the final day. Thousands of people will hear about the ARISS Challenge Coin and how ARISS inspires students to engage in STEM studies and radio technology. 2018 Hamvention Prize Committee Chairman Bill Serra, N8NRT, wrote, "We are happy to be able to make the ARISS Challenge Coin a very special part of Sunday's prize awards." ARISS donated two of its handsome coins positioned side by side in a beautiful display, showing off each of the coin's sides. This ARISS Challenge Coin is the premium received by donors who give $100 or more to ARISS. The ARISS team will welcome convention goers at the ARISS booth in Building 1 through the weekend to donate and see a mock-up of the Multi-Voltage Power Supply that ARISS will launch in the future. A raffle is being held at the booth to win a coin-the owner of the ticket pulled does not have to be present to win. For those unable to make the trip to Xenia, readers can donate any amount by going to http://www.ariss.org/donate.html ARISS thanked everyone on the Hamvention staff whose personal efforts are aiding ARISS in its fund-raising and publicity goals. Rosalie White, K1STO, ARISS-US Delegate for ARRL, added: "We are so pleased and proud to know that Hamvention believes in the ARISS team and its goals of piquing the interest of young people and communities in a quite unique "wow way" for STEM and Amateur Radio." 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. For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

Hello folks, hope someone can give me an hand. Finally I had success to interface the Funcube Dongle Pro Plus with the Wisp program Using the SDRSharp program, the Wisp program and Andy's UZ7HO High Speed SuondModem program All interfaced with the HW Virtual Serial Port. It worked great but now I would like to insert in this loop my Kenwood TS-2000X to transmit To the satellite to request the DIR or the messages. Anybody can point me how to do it? Any help will be really appreciated. 73's de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

Good laugh, when I read the Subject line. TLEs are like fresh fruit and baked bread .... Best when first acquired ... with diminishing returns since picked or baked. w9gb

Re: [amsat-bb] IC-706MKIIG work through satellites

Oh, I forgot to mention - be sure to start at "L" Tx power on the linears and work your way up from there. As I said below, I don't have experience as to how each of the "L, 1-9, H" power settings are correlated to the published max values for 70cm and 2m, but more than 5 watts on the linears can cause serious problems for some sats (AO-07) and can cause annoying problems for other users on all of them. --Roy K3RLD > Max, I have recently purchased the same transceiver.

Max, I have recently purchased the same transceiver. If you plan on operating half duplex on linear sats, check out W5PFG's video here: https://youtu.be/vke3pWkKULU Not the same transceiver, but what Clayton shows is how to operate using a split frequency with the A and B VFO's, which the 706 also can do. If you have a second transceiver, or a receiver (such as a decent SDR), then you can operate full duplex. I have not attempted either, yet (as weather has not be cooperating here in the Northeast USA). FM is basically the same (half duplex with split frequency), but you need to enable tone on uplink vfo for full functionality (and much less tuning, especially on 2m). --Roy K3RLD > Good afternoon, Tell me, please, what I need to start working through > satellites using > this transceiver.
