Searching for Az/El Rotor
by iz1dsj＠sparks.it 10 Aug '08

10 Aug '08

While on holiday I started planning a sat station, so I'm searching for an used Yaesu 5400/5500/5600 rotor system. If somebody wants to sell his one, possibly in Europe (coustoms and shipping would be less expensive), contact me, otherwise in September will buy a new one :( Hi! Thanks.

satellite orbiatl prediction through obersvation
by Bob DeVarney W1ICW 10 Aug '08

10 Aug '08

I. have been reading up on the history of the Kettering group and I am particularly curious about one thing: how did they determine the orbit of the satellite strictly from observation. Can anyone help me with this? I can see how you could pick up the period of the satellite from observation, but am stumped as to how the rest of it is worked out... Thanks and VY 73 de W1ICW

AMSAT NEWS SERVICE ANS-223 ************************************************************** *** 2008 AMSAT Space Symposium and Annual General Meeting *** *** October 24-26 in Atlanta, Georgia *** ************************************************************** ANS is a free, weekly, news and information service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. Please send any amateur satellite news or reports to: ans-editor(a)amsat.org In this edition: * Falcon-1 Launch Failure * THE PERSEID METEOR SHOWER ON AUGUST 12 * "Nanosputnik" Cubesat "Polar Lights" * ARISS Status - August 4, 2008 * Satellite Shorts * AMSAT-UK Colloqium SB SAT @ AMSAT $ANS-223.01 Falcon-1 Launch Failure AMSAT News Service Bulletin 223.01 From AMSAT HQ SILVER SPRING, MD. Augugst 10, 2008 To All RADIO AMATEURS BID: $ANS-223.01 SpaceX's Falcon-1 rocket lifted off from the Kwajalein atoll on 03 August 2008 at 0334 UTC. On board was the Trailblazer satellite for the Jumpstart Program of the United States Department of Defense’s Operationally Responsive Space Office (ORS). Also on board where two triple-cubesats, PRESAT & NANOSAIL-D, from NASA which had beacons in the amateur 70cm band. Unfortunately, an anomaly occured approximately 2 minutes 20 seconds into the flight. The engineers said the rocket stages did not separate and the second stage did not ignite. SpaceX has announced that the problem with the last launch was that the first stage regenerative engine continued burning longer than they expected. It therefore bumped into the second stage after separation. A new downward looking video that includes this action is available at: http://mfile.akamai.com/22165/wmv/spacex.download.akamai.com/22165/F1-003.a… [ANS thanks SpaceX and Bruce, VE9QRP, for the above information] /EX SB SAT @ AMSAT $ANS-223.02 THE PERSEID METEOR SHOWER ON AUGUST 12 AMSAT News Service Bulletin 223.02 From AMSAT HQ SILVER SPRING, MD. Augugst 10, 2008 To All RADIO AMATEURS BID: $ANS-223.02 HAM RADIO IN SPACE: THE PERSEID METEOR SHOWER ON AUGUST 12 Meteor scatter enthusiasts attention. The annual Perseid meteor shower peaks on Tuesday, August 12th. The best time to see them and make contact by bouncing signals off their ionized tails is during the dark hours before dawn on Tuesday morning when forecasters expect 50 to 100 meteors per hour. The source of the Perseids is Comet Swift-Tuttle, which has littered the August portion of Earth's orbit with space dust. The dusty zone is broad and Earth is already in its outskirts. As a result, even before the peak on August 12th, you may see some "early Perseids" streaking across the night sky. (VHF Reflector) [ANS thanks ARRL for the above information] /EX SB SAT @ AMSAT $ANS-223.03 "Nanosputnik" Cubesat "Polar Lights" AMSAT News Service Bulletin 223.03 From AMSAT HQ SILVER SPRING, MD. Augugst 10, 2008 To All RADIO AMATEURS BID: $ANS-223.03 I am asked by Alexander Zaitev RW3DZ of the Izmiran Institute, in Troitsk outside Moscow, Russia, to publicise his proposed "Nanosputnik" Cubesat "Polar Lights." FYI the Izmiran Institute made the first spaceborne magnetometer, on Sputnik-3 in 1958. It is at: http://www.izmiran.ru RW3DZ recently referred to the Nanosputnik Cubesat in a blog at: http://www.vhfdx.ru/sputnikovaya-svyaz/50-let-kosmicheskoy-eryi and on his website at http://rk3dxb.narod.ru/polar_lights.html He is establishing a team within the promotion of amateur radio to young people around the RK3DKB club shack at Troitsk. John G7HIA and I were welcomed there last Sunday. The Nanosputnik is proposed to be built on a 10cm Cubesat frame and to weigh 1 Kg. Command uplink will be in 2 metres and data downlink at various data rates in 70cms, there are precise frequencies given but it is probably unwise for me to give them out at this stage as the satellite is not built yet and I do not know whether IARU frequency coordination has been undertaken. There may be an experimental 5 GHz beacon. The proposed payload is a unique magnetometer which will detect fluctuations along the flux lines of the magnetosphere and will be oriented along the flux lines within 1 degree by an on-board GLONASS/GPS. Data sampling will be 1 observation/second and he is interested in downloading every quarter orbit into the GENSO network. There is also scope for a CCD camera and cosmic ray detector. Orbital life is estimated as 3 years with rechargeable batteries and a solar panel charging system. I do not have any information about launch opportunities. John G7HIA and I will continue to work with RW3DZ and will bring any other information we have to this bb as we get it, although we are not responsible for this Nanosputnik in any way whatsoever. [ANS thanks Andy, G0SFJ for the above information] /EX SB SAT @ AMSAT $ANS-223.04 ARISS Status - August 4, 2008 AMSAT News Service Bulletin 223.04 From AMSAT HQ SILVER SPRING, MD. August 10, 2008 To All RADIO AMATEURS BID: $ANS-223.04 1. Upcoming School Contacts Two simulated Amateur Radio on the International Space Station (ARISS) contacts are scheduled for Tuesday, August 5 with U.S. deployed soldier dependents visiting Euro Space Camp (ESC) in Belgium. These training sessions are terrestrial-based amateur radio contacts using ARISS-equivalent equipment. There will be EchoLink and IRLP coverage of both contacts. • The first simulated contact is scheduled with Koichi Wakata, KC5ZTA, at approximately 14:20 UTC. • The second simulated contact will take place with astronaut Soichi Noguchi, KD5TVP, at approximately 14:50 UTC. An Amateur Radio on the International Space Station (ARISS) contact has been scheduled with Town of Berkeley Heights, New Jersey, Summer Playground Camp on Wednesday, August 13 at 16:08 UTC. The New Providence Amateur Radio Club has been involved with this camp for the last four years. It has provided an introduction to ham radio on the air by setting up HF and VHF stations and having the campers communicate with hams around the world. The ARISS contact will be an extension of this activity. 2. United Space School Contact Successful An international group of high school students attending United Space School in Seabrook, Texas experienced an Amateur Radio on the International Space Station (ARISS) contact on Thursday, July 31. Telebridge station ON4ISS in Belgium facilitated the contact. Twelve students had16 questions answered by astronaut Greg Chamitoff, KD5PKZ. The audio for this event was fed into the EchoLink AMSAT (101 377) server, receiving 10 connections and it was also fed into the JK1ZRW (277 208) server. 3. ARISS Meetings Held The annual Amateur Radio on the International Space Station (ARISS) Face to Face Meeting was held in Moscow on July 17-18. Status reports were given by all committees and the election of officers was held. This meeting was preceded by the first Amateur Radio Working Group (ARWG) conference and was followed by a Technical Interchange Meeting (TIM) on July 21-23 where discussions covered SuitSat-2 and ARISS hardware. A final meeting was held at the Gagarin Cosmonauts Training Centre (GCTC) to discuss astronaut training on the ARISS equipment. All meetings were successful, much was accomplished and minutes will be available in the near future. 4. NASA Posts ARISS Article to Web Site An Amateur Radio on the International Space Station (ARISS) article has been written and posted to NASA Web sites. Several ARISS members were interviewed for the story, including astronaut Bill McArthur, KC5ACR. “Communication From Space Inspires Young Minds” may be found at: http://www.nasa.gov/mission_pages/station/behindscenes/index.html (and on the Kennedy site http://www.nasa.gov/centers/kennedy/news/index.html under "Features").

Luc: Responding to your comment below: ------------------------ >From: Luc Leblanc <lucleblanc6(a)videotron.ca> >Very nice presentations. One attract my attention was made by Peter Guelzow DB2OS one one of his slide we can read: >ATTRACTIVENESS OF AMATEUR RADIO HAS DROPPED SIGNIFICANTLY >FUNDING A SATELLITE FROM AMATEUR RESSOURCES ALONE NEVER WORKED BEFORE AND WILL NOT WORK NOW. >I don't how to explain how all the wisdom and reality knowledge seems to be concentrated in Europe when speaking about >>amateur satellite? ----------------------- I agree with Peter. And as a member of AMSAT-NA and a person that resides in NA, I have said these statements publically many times. Actually, one of my last postings addresses item #1 in your e-mail. Also, it goes without saying that #2 is an imperitive. The only reason that the ARISS team has been able to acquire 9 launches of hardware to ISS since 2000 is that the space agencies have a stake in our activities as it supports getting students from 6 years old to college age interested in science, technology and mathematice. They are willing to invest in these flights because they see a benefit to them as well as society. So I think this wisdom is shared worldwide. Frank H. Bauer, KA3HDO

Pave pawns QRM?
by Luc Leblanc 09 Aug '08

09 Aug '08

On an SO-50 pass this evening i heard over pile up the distinct Pave Pawns signal (braw braw braw) pulsing signal. I don't know if the system is able to generate harmonics down to the 2 meter band? If it was not pave Pawns it is something i heard on AO-40 and that was triggering LEILA at that time? Anyone else on that pass heard that?
