ARISS Clarification--Please Read
by Frank H. Bauer 08 Sep '08

08 Sep '08

All, In the past 24 hours, two e-mail "Press Releases" were sent out by Miles Mann, WF1F, about ARISS related activities. Please ignore these e-mails as they are not totally accurate and Miles was given direction to not release this information. What was accurate is that the ARISS team has been working very closely with Richard Garriott, W5KWQ, his father Owen Garriott, W5LFL, the International Space agencies and Space Adventures on ARISS related activities for Richard's flight which is planned for mid-October. This includes several educational outreach contacts with the USA-based Challenger Centers, several other internationally based schools, some opportunities for general QSOs and, if the hardware is flown, an opportunity to receive some SSTV downlinks from Richard. However, the ARISS team is still working out the specifics on this initiative. We have not totally vetted these specifics through the ARISS international team. We have not completed coordination of our efforts with the requisite space agencies---RSA/Energia in Russia and NASA in the USA. And we have not completed coordination of our efforts with Space Adventures, who is working with the Russians to fly Richard on the Soyuz to ISS. I hope you can be patient with the ARISS team as we work this coordination out. We should be able to provide additional details in the next 14 days. And I hope you all get prepared for a lot of excitement this fall. Richard Garriott will fly almost 25 years after his father, Owen, W5LFL, made history as the first ham radio operator to communicate from a vehicle in space. And Mike Finke, who flies up with Richard, will take the helm as the ISS Expedition 18 Commander. Mike is a true ham radio enthusiast who plans to keep the ARISS microphone hot with lots of QSO excitement. On behalf of the ARISS international team I appreciate your patience on this and thank you all for your interest in the ARISS program. 73, Frank H. Bauer, KA3HDO AMSAT-NA V.P. for Human Spaceflight Programs ARISS International Chairman

AO-51 L/S MODE
by Luc Leblanc 08 Sep '08

08 Sep '08

Using the same S band converter that i was using with AO-40 i succeed to have some QSO on AO-51 VE2NPC and another station but i am not 100% sure of his callsign. First i think Squidly Diddly will be the type of operator best equipped to handle my station in L/S mode on a LEO sat. I am using my PCR- 1000 to have a graphical display of my up converter output on the scope display. Since my first attempt on L/S mode i found very hard to be on the right uplink frequency. This morning pass i heard Clare VE3NPC transmitting a couple of time to find the right uplink frequency on my side even adjusting as per the Orbitron doppler corrected uplink i was always out of the satellite L band receiver until i start to adjust my TX frequency lower and higher than the program displayed frequency. I ended up with a 15KC higher than the "supposed" doppler corrected frequency on Orbitron? Could be my upconverter is not properly aligned or the scope display on the PCR-1000 software is not too exact at 1.268GHZ? At the end i will have to set the satellite RX frequency 15KC up to be able to get in the RX pass band. Next step is to have my uplink frequency controlled by my PC as i need 2 additional arm here in the shack! Bottom line L/S is feasable and with some tweeking it can probably matched the V/S mode +- the obstacles and foliage blocking in the path.

Re: COMPASS commands
by Mike Rupprecht 08 Sep '08

Hi Doug, all this beacon looks good. COMPASS made no hard reset and all settings are valid. Yesterday evening I heard the beacon and the temperature was 0° . So I commanded the satellite to switch off the heater at 0 degr. It seems that has worked. After this command I sent the treshold value to -50 degr. Now we can see that the heater is still off (also at low temperatures). This evening I will try to change the voltage treshold - maybe I can switch COMPASS into powersafe mode. That means we can hear the beacon every 3 minutes. Please stay tuned and listen to the beacon. Thank's a lot for all your efforts. 73, MIke DK3WN Betreff: Re: [amsat-bb] COMPASS commands Gesendet: Mo, 08. Sep 2008 Von: Douglas C.

This meeting is being jointly organised by the Royal Observatory of Belgium (ROB), ESA, the SWWT, the COST 724 and COST 296 communities. The local organisation is done by the SIDC of the ROB. This event will build on the advances made during previous European Space Weather Weeks and preceding ESA Space Weather Applications Workshops. The ESWW will again adopt the central aim of bringing together diverse communities working on all elements of space weather with a strong focus on user involvement. This year’s meeting will discuss recent advances in both scientific and applications based domains and how these advances relate to user needs. It will also provide an opportunity to discuss the Space Weather community’s contribution to possible future ESA action in the area of Space Situational Awareness. New data, tools and techniques will also be discussed and demonstrated during the workshop with a view to aiding the transition between new scientific results and user-oriented space weather services. This year’s event will include a space weather fair, where users and service providers will have the opportunity to interact in an informal working environment. The meeting will also include a number of hands-on splinter sessions and will explore community development through several dedicated business meetings. Organisation: The meeting will centre on 6 open sessions that address a number of topical themes: Session 1: Space Weather and the European Approach to Space Situational Awareness Session 2: Global Navigation Satellite Systems : Science, user needs and applications Session 3: Offshore Drilling, Magnetic Surveying and Geomagnetism : Science, user needs and applications Session 4: Space Weather Models: from Research to Operations Session 5: New and Existing Data Resources, Tools and Services Session 6: Solar Weather: New results, analysis techniques, forecast tools and the outlook for users Each session will be divided into oral and poster session with plenty of time devoted to discussion. Contributed papers are welcome to each of the 6 sessions. The oral presentations will cover a range of scientific and applications related themes and will consist of both invited and contributed papers. User contributions are expected to feature strongly in sessions 2 and 3 in particular. It is also envisaged that the meeting will conclude with a wrap-up of the key issues arising during the week long event in the form of a round table discussion on future European directions in space weather. Business meetings: A key part of the European Space Weather Weeks are the business meetings. These meetings provide the opportunity for interested participants to meet in smaller groups and address key issues in a style that compliments the open format of the plenary sessions. These meetings take the form of working meetings with reports produced and actions taken by the participants. This year, time during the ESWW5 schedule will be set aside for all splinter meeting convenors to report the main conclusions of the meetings to the full workshop. Topics that will be covered by splinter meetings during this year's ESWW include: Science Consortium for SWAP and LYRA payloads onboard PROBA2COST 295 "Mitigation of Ionospheric Effects on Radio Systems (MIERS)SOTERIA (SOlar TERrestrial Investigations and ArchivesSpace Weather Measurements with the Vega Maiden Flight CubeSatsSpace Weather and Health IssuesSWENET Developers ForumSpace Weather IndicesSWWT Plenary Meeting #24SWWT Topical Group on Atmospheric EffectsSWWT Topical Group on Ionospheric EffectsSWWT Topical Group on Spacecraft, Launcher and Aircraft EnvironmentsData and Application Services: Current Status and Future NeedsSpace Weather Impacts on Materials For further information and business meeting abstracts, see the online agenda.

Meeting: Modern Challenges in Nonlinear Plasma Physics ********************************************************************** From: Dimitris Vassiliadis MEETING: "Modern Challenges in Nonlinear Plasma Physics: A conference honoring the career of K. Papadopoulos" June 15-19, 2009, Sani Resort, Halkidiki, Greece First Announcement In the last three decades theoretical and experimental progress has led to a substantial integration of nonlinear effects in modeling and understanding of plasma dynamics. Particle acceleration mechanisms, collisionless shocks, magnetic reconnection, and flow and wave turbulence are only a few of the facets of complex dynamics in space or laboratory plasmas. Moreover, the realistic behavior of plasmas in geospace, solar, and fusion environments is modulated by strong interactions with adjacent plasmas or boundaries. Large-scale coherence emerges even in weakly-coupled, multi-scale plasmas. Accurate modeling and prediction of nonlinear plasma systems has demanded development of new theoretical and numerical methods. The meeting will review recent key developments in these areas and help chart the exciting future of nonlinear plasma science.

COMPASS commands
by Mike Rupprecht 08 Sep '08

08 Sep '08

Hi all, I got a lot beacons and we can see that COMPASS survives all the eclipses. The battery voltage is increased to 3.67 volts. Please keep on trying to listen the beacon and send the following commands: ****13#200# threshold heater off to -55 degr ****14#200# threshold heater on to -55 degr ****15#255# low batt threshold to max -> charge batteries ****16#255# critical batt threshold to max -> emergency mode (to save power) If COMPASS receive this sequence successfully you can hear a short confirmation beep. Uplink: 145.980 MHz FM Downlink: 437.275 MHz Thanks for your time and your efforts! 73, Mike DK3WN

mode S - results - first attempt
by Michael Heim 07 Sep '08

07 Sep '08

First attempt at hearing mode S. pass wasnt the best, max elevation about 15 degrees. receiving using a California Amplifier model 130099. This is the MMTS unit with the integral yagi with the washer shaped elements. Yagi boom length about 2 feet, supposedly 16 dBi gain on 2500 MHz. Modified with the tape over the hairpin tuning, etc.... original crystal, received on 123.2 MHz. Used an FT-50R for the IF. Here is what I found: Unit is linear polarized. Heard the bird far better using vertical polarization. There may have been some tropo, as the time of the pass was about an hour after sunset. Temperature cooled off about 15 degrees in the 2 hours preceeding the pass. Signal strength ranged from full quieting to "in the noise". with a slow fade to it. Heard the bird 3 degrees above the northern horizon when there was a peak in propagation. Beasmwidth is workable, but it is tight enough that I'll need an elevation rotator. I'm not using one on V/U. I do not have L band capability (yet), this was just a receiving test, but I do hope to be able to work U/S or V/S if the bird is capable. Wonder if this is typical for this mode. Now some quirks regarding my own gear: The LO is about 150 KHz off frequency, but thats not really a big deal. I just discovered I had the receiver set to AM. Here I was slope detecting the thing! The HT is capable of FM, I was set to AM because I had a brain lapse when I was pre-checking things before the pass. Then I forgot to change it back for the actual pass. Trees REALLY kill the signal! I kinda expected that though. Looking forward to tersting tomorrow during higher and earlier passes, and of course...using FM to receive! I have another converter yet to be tried. The other one has an N connector for connecting to an external antenna. I see many ops use helicals. How many turns is considered good for this bird ? Michael Heim ARS KD0AR (EN90rw)

CP4 Faulty Voltage Sensor Fully Characterized
by Jason Lionel Anderson 07 Sep '08

07 Sep '08

Fellow Hams, Thanks to all who have helped us tracked CP4 in its time of need. With the extra packets we've been able to fully characterize one of our voltage sensors as it deteriorated. This information will be helpful in predicting sensor failure for our other on board sensors. Even though CP4 is no longer in an emergency state, we still welcome and appreciate any data you can collect from CP4. Unfortunately though, CP4 seems to have reentered its brain dead state where it no longer beacons. Hopefully this problem fixes itself soon so more data can be collected. On a more positive note, we are planning to launch our next satellite CP6 near the end of this year on a Minotaur from Wallops, Virgina as a secondary to TacSat 3. Our current plan is to release data acquisition software to the community to make life for those who would like to track CP6 easier. Stay tuned for more! - Jason Anderson, KI6GIV California Polytechnic State University

COMPASS recovery reports
by Mike Rupprecht 07 Sep '08

07 Sep '08

Hi all, I don't want to impose but I received some good COMPASS beacons from Japan. COMPASS has no reset since several eclipses and remains on! The voltage is increased to 3.67 volts and the heater is partial OFF (depends on temperature). Now it's important to observe the beacon and send the commands for changing the heater threshold. My next pass is at 1900UTC - so I am on pins and needles. I hope you'll back my plan. Thank you all for your efforts. 73, Mike DK3WN

Hi all, just heard a very good sounding beacon from COMPASS. 07.09.2008 09:50UTC 70074030370000210100b807ff --------------------------------------------------- Solar Cell Voltage 2.20 V Solar Panel 6 Cur 43.92 mA Solar Panel 2 Cur 0.00 mA Solar Panel 3 Cur 345.10 mA Solar Panel 4 Cur 301.18 mA Solar Panel 5 Cur 401.57 mA EPS Reset Counter 0 Power Level Critical Battery Capacity Heater Active Battery Heater ON Power Safe Counter 1 Emergency Mode Counter 0 Battery Voltage 3.61 V Battery Current 43.92 mA Battery Temperature -1 °C Voltage increased and powersafe counter as well. That means no reset during the last eclipse. Can somebody try to send the commands, please ???? Thanks , 73 Mike DK3WN

COMPASS-1 recovery efforts
by Mike Rupprecht 07 Sep '08

07 Sep '08

Hi all, Thanks for all the reports and beacons I received over the last 3 weeks. The Voltage has never climbed over 3 volts (in full sunlight). We can assume that COMPASS is totally OFF during eclipses. If COMPASS enters the sunlight she will reboot. Because the low voltage COMPASS is switching into emergency mode. That means, that CDHS (Command & Data Handling Subsystem) and ADCS (Attitude Determination and Control Subsystem) units are completely off. Unfortunately this means also, that we CAN NOT change the threshold values by commands. That's the main problem. It seems the satellite is "locked" because in emergency mode she will accept only two commands: hard reset and TX enable. Both commands are impractical for recovery. The only thing we can do is WAIT. Wait for longer sun periods and voltages over 3.47 Volts. That's the standard threshold value in emergency mode to switch into powersafe mode. Only in this mode we can change the threshold values. We may have lost a cubesat, but we've definitely got some new friends :-) Thank you all for your efforts! 73, Mike DK3WN

Re: AT&T's DSL Internet service
by RFI-EMI-GUY 07 Sep '08

07 Sep '08

Perry; I have had recent experience with ATT DSL. About 8 months ago My wife decided to change our COMCAST cable service to an ATT DSL/DishNetwork bundle. (She did this w/out consulting me!) She was assured by ATT that the DSL service would provide the same or better than 6 gig service we were enjoying (trouble free) from Comcast. In fact ATT made a big point that using a cable modem we were sharing bandwidth (you still do with DSL upstream of the DSLAM). Truth be told, ATT could not deliver 6 gig service to our home 15,000 feet from the DSLAM. The copper network is very old and deteriorated. In fact after having troubles: 1) they wanted to downgrade the GOS, 2) They no longer offered the 6 gig GOS to my block. I also spent a lot of time rewiring the phones in the house to deal with DSL filtering issues. ATT's real reason to market the DSL/Dishnetwork bundle is to pull customers from the local cable service in anticipation of their fiber to home video service that they are slowly rolling out. I would avoid ATT DSL unless you have a DSLAM in your neighborhood and you have neighbors who are satisfied with the service. Otherwise, steer clear. Also the DishNetwork service has been a bit troublesome in performance and HD channel packages. So now I am back with Comcast for internet and stuck with Dishnetwork HDTV for 10 more months. Also ATT has blocked usenet binaries groups so if you were getting manuals, files and schematics from ABSE or similar newsgroups, you are out of business. Has anyone on the BBS had any experience with AT&T's DSL Internet service???? I will be using a Apple IMac computer and the people here in town don't seem to know anything about a Mac computer. I would also like to know if upgrading to DSL will cause any interference on my TS2000???? Perry WB8OTH-- Joe Leikhim K4SAT "The RFI-EMI-GUY"© "Treason doth never prosper: what's the reason?

ARISS Clarification--Please Read
by Bauer, Frank H. (GSFC-590.0) 06 Sep '08

06 Sep '08

All, In the past 24 hours, two e-mail "Press Releases" were sent out by Miles Mann, WF1F, about ARISS related activities. Please ignore these e-mails as they are not totally accurate and Miles was given direction to not release this information. What was accurate is that the ARISS team has been working very closely with Richard Garriott, W5KWQ, his father Owen Garriott, W5LFL, the International Space agencies and Space Adventures on ARISS related activities for Richard's flight which is planned for mid-October. This includes several educational outreach contacts with the USA-based Challenger Centers, several other internationally based schools, some opportunities for general QSOs and, if the hardware is flown, an opportunity to receive some SSTV downlinks from Richard. However, the ARISS team is still working out the specifics on this initiative. We have not totally vetted these specifics through the ARISS international team. We have not completed coordination of our efforts with the requisite space agencies---RSA/Energia in Russia and NASA in the USA. And we have not completed coordination of our efforts with Space Adventures, who is working with the Russians to fly Richard on the Soyuz to ISS. I hope you can be patient with the ARISS team as we work this coordination out. We should be able to provide additional details in the next 14 days. And I hope you all get prepared for a lot of excitement this fall. Richard Garriott will fly almost 25 years after his father, Owen, W5LFL, made history as the first ham radio operator to communicate from a vehicle in space. And Mike Finke, who flies up with Richard, will take the helm as the ISS Expedition 18 Commander. Mike is a true ham radio enthusiast who plans to keep the ARISS microphone hot with lots of QSO excitement. On behalf of the ARISS international team I appreciate your patience on this and thank you all for your interest in the ARISS program. 73, Frank H. Bauer, KA3HDO AMSAT-NA V.P. for Human Spaceflight Programs ARISS International Chairman

September 7, 2008 To All RADIO AMATEURS BID: $ANS-251.03 AMSAT-NA VP Operations, Drew KO4MA reported this week, "It looks like the temperature has come up enough on AO-16 so that the watchdog problem has gone away. On September 1, I turned the satellite on collected some telemetry, and then commanded it into bent pipe mode which is VHF-FM up and DSB-UHF down." The command team will monitor http://oscar.dcarr.org/ and amsat-bb. If the satellite goes quiet they will endeavor to restart it as soon as possible. Occasional interruptions to gather telemetry are likely. Just as a reminder, AO-16 now operates as a cross mode, cross band voice repeater, with an uplink on 145.920 FM. The downlink is reduced carrier AM, similar to double sideband, on 437.026. Most stations find receiving the downlink on USB works best. Work is continuing to predict how long this latest period of operation may last, but initial estimates are around 2-3 months total, symmetric around a period of continuous illumination in October. There may not be another opportunity after this one, as the satellite will generally head towards longer eclipses (and lower temperatures) for several years.

The contact will be facilitated by telebridge station WH6PN in Hawaii. During the event, Scouts will earn the Space Exploration Merit Badge, which includes the Mars Mission Design and the Moon Base Model construction. NASA DLN will assist with teaching these two topics. Scouts will design and launch water rockets and explore robotic technology. Segway of Chicago will assist in Robotics education. Participants will also complete many of the Radio Merit Badge requirements. The local rocket club will provide rocket launches throughout the event, two during the outdoor viewing of the movie "October Sky." The event will conclude with a hot air balloon launch. Boy Scouts (ages 11-17), Cub Scouts (ages 6-10), and adult volunteers have been invited to the event. The Space Jam- boree has attracted the attention of regional media outlets. Four television stations, radio stations, and local newspapers are planning features on the Space Jamboree. 2. Swiss Contact Successful On Saturday, August 30, youth attending Schulehaus Feld 1 in Richterswil, Switzerland participated in a successful ARISS contact via telebridge station VK4KHZ in Australia. To prepare for the event, children produced drawings, plays, research papers and multimedia products which were dis- played the day of the contact. More than 500 students, parents, teachers and visitors gathered in the sports hall to watch as 21 students posed questions to Greg Chamitoff, KD5PKZ, aboard the ISS. Additionally, an audio link was set up outside the sports hall for other visitors to listen in. Two television stations (SF DRS Aktuell Schweizer Fernsehen, Regional Fernsehen Tele Zürich), one radio station (Radio Zürichsee) and three newspapers (Zürichsee Zeitung, Neue Zürcher Zeitung NZZ, Tages-Anzeiger) covered the event. The audio was fed into the EchoLink AMSAT server, which received 12 connections, and also into Internet Radio Linking Project (IRLP) Reflector 9010. 3. ARISS Presentation Given at CLC Conference The Challenger Learning Center (CLC) Lead Flight Directors Conference was held in Wellington, Kansas on August 24 - 28.

Hi all! For those interested in different grids, I'm going south of Phoenix for the AO-51 pass this evening (early Sunday on the UTC clock) at 0150 UTC. I'll park on the DM32/DM42 grid boundary, north of I-8 in Pinal County, Arizona. I haven't been down here in a couple of months, and enjoy handing out the unusual grid DM32 from a location not on a military bombing range - and without having to cross the border into Mexico. 73!

Good Afternoon everyone! I wanted to be the first to thank Drew and the AO-51 Command Team in advance for scheduling the Second Channel for September. It is appreciated, to say the least. That being said, according to AMSAT.org, AO-51 has the "capability" to do PSK31: *Mode A/U Digital: Operational* Uplink: 28.1400 MHz PSK 31 BPS Downlink 435.3000 MHz FM 31 BPS Has this ever been activated? If it is possible, how has it worked out before? Thanks again!
