SB SAT @ AMSAT $ANS-164.03 AMSAT Forum at Dayton Hamvention Videos Ready to be Viewed On-line AMSAT News Service Bulletin 164.03 >From AMSAT HQ SILVER SPRING, MD. June 13, 2010 To All RADIO AMATEURS BID: $ANS-164.03 If you weren't able to attend the Dayton Hamvention this year, you missed five interesting and informative presentations at the AMSAT Forum. The complete presentations are now available on the AMSAT website at http://www.amsat.org. From the menu on the left side of the home page, select "AMSAT Video News". The direct link to the AMSAT Video News Page is: http://www.amsat.org/amsat-new/information/videoNews.php Here's what you'll find: Barry Baines, WD4ASW, AMSAT President, "AMSAT Status Report" AMSAT President Barry Baines highlights current activities within AMSAT and discusses some of the challenges facing the organization. Drew Glasbrenner, KO4MA, AMSAT VP Operations, "AMSAT Satellite Oper- ations and International Satellite Operations". Drew discussed oper- ational AMSAT satellites and described new and future international Satellites. Mike Forsythe, AC2V, "Integrating Satellite Operations into DXpeditions" Mike, K4T Team Leader described the planning and execution of the K4T DXpedition, and how to have satellite operations be a major part of DXpeditions, involving youth and making it all work on green power! Gould Smith, WA4SXM, AMSAT VP User Services, "Getting ARISSat-1 Ready to Fly". Gould is the AMSAT Project Manager for ARISSat-1 and talked about the evolution of SuitSat-2 to ARRISat-1, the current status of the satellite project, and the testing and delivery of two satellites to Russia in July. Roger Westgate, WC2R, "NextGen CubeSat Program Update". Roger delivered the update prepared by Alex Harvilchuck, N3NP, a Systems Engineer with IBM and the NextGen CubeSat Program Manager. A team of engineering students from the State University of New York (SUNY) at Binghamton have been modifying the power systems from ARISSat-1 for use in a 3U CubeSat with a U/V linear trans- ponder, for AMSAT. The files are in Windows Media Video (.wmv) format and will work with Internet Explorer and Windows Media Player on a PC, Safari and QuickTime (with .wmv plug-in) under OS X on an Apple Macintosh, and with a .wmv player under Linux or other operating system.

[amsat-bb] Re: VO-52 - OK to Work in FM?
I don't, and I think that VU says basicaly that it's ok if you haven't anything else - so why foul up the transponder or others by grabbing its power? I can see it MIGHT be acceptable if you were testing a rig. but not to treat as '51, IMHO. But AMSAT-VU will say for sure, it's their bird. 73 de andy G0SFJ ___ Sent via amsat...@amsat.org.

IKAROS is an interplanetary spacecraft: http://www.jspec.jaxa.jp/e/activity/ikaros.html so one would need very good telescope or access to something like NASA's Deep Space Network. 73s Bernhard VA6BMJ @ DO33FL ___ Sent via amsat...@amsat.org.

Hi Alan, BA1DU The HO-68 schedule- 13-20 June 2010 is very bad for South Europe because in the Mediterranean area only two orbits are useful with an elevation with no more than 45 degrees. 15 June 2010 19:05...Turn On and 19:50...Turn Off 17 June 2010 18:50...Turn On and 19:35...Turn Off All orbits overhead for Europe HO-68 is not scheduled and the transponder is Turned-Off Wery tired to make calculations every week for very small ! 73" de i8CVS Domenico ___ Sent via amsat...@amsat.org.
