LVB Tracker USB serial port driver for Windows 7 x64?

by Bill Bordy, NJ1H

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

Re: [amsat-bb] Free content from six satellites via Outernet (APRS?)

by Robert Bruninga

Global Ham channel? We should find someone to work with the OUTERNET folks to add an amateur radio channel to their downlink. Their satellites could provide connectivity to 99% of amateur radio operators on earth. In addition, Ham Radio can bring to OUTERNET an uplink capability that they currently don't have. And the uplink can be from the same remote areas where there is no service... How? Like this. They simply take the APRS packet data stream from the global APRS Internet System (APRS-IS) and stream it in their downlink for hams. Then hams anywhere on earth can transmit traffic via HF back into the system. Since the APRS-IS is one of the world's largest HF receiver-diversity receiver networks in the world, then a packet transmitted from almost anywhere on earth has a reasonable chance of being heard at least once at least somewhere and interjected back into the network, where it gets to the OUTERNET and then in the downlink. The only question, is the atrophy of our HF IGates? Years ago, the HF channel on 10,147.2 MHz had receivers all over the world. I have not listened much recently, but maybe there is still a viable network there. And if not, maybe we could re-invigorate it if it meant global APRS connectivity for ham travelers and hams in remote areas. An HF packet transmitter can be as small as a cigar box and solar powered. Has anyone tuned in the OUTERNET downlink? I have heard anyone with OUTERNET's free ORxPi software and a Raspberry Pi can get the OUTERNET content when plugged into a DVB-S tuner. Then there is of course the arm-chair-lawyers concern of rebroadcast of amateur radio content on a non-ham network?

Some of you may be aware of us but I suspect most are not. I am writing this email to introduce Outernet to AMSAT. Outernet broadcasts a DVB-S signal <https://wiki.outernet.is/wiki/Coverage_and_transponder_settings> from six different satellites covering 99% of humans on Earth. We created this information service to reach the 4.3 billion people who do not have Internet access and designed it to overcome the problems the Internet presents, namely download speed and recurring cost. Our datacast is completely free to receive, our bitrate is 90 Kbps (~1 GB/day of content), and you can even build your own receiver with a Raspberry Pi <http://store.outernet.is/>. Right now, the content we send is curated by us and a group of editors but we are working on a Reddit/Wikipedia/YouTube mashup where the contents of our broadcast can be decided publicly. Currently, we broadcast Wikipedia, 30,000+ ebooks, PLOS One journal articles, Khan Academy, CK12 textbooks, music from SoundCloud, and more. I want to invite this community to be involved in Outernet and help us build this project. Our current focus is on developing channels to get devices into schools and generally into countries/areas where Internet penetration is very low. Our forum <http://discuss.outernet.is> is very active with users and Outernet staff. Please stop by!

AO-16 telemetry 3 Oct 2010

by Mark L. Hammond

Hi All, Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to get some telemetry packets. The satellite would remain on for less than one minute after being commanded on. A quick test of the "bent pipe" voice mode repeater was successful. . The "hardware watchdog timer problem" is still evident; as expected, spacecraft temperatures are insufficient to keep the transmitter ON (needs to be above 15 deg C). Orbit projections suggest that satellite illumination conditions will not result in increased temperatures for nearly 10 years. Command stations do periodically turn AO-16 "ON" to check on its condition and see if the hardware timer problem has "automagically" fixed itself (which in not anticipated, but who knows...).

Upcoming ARISS contact with National Soaring Museum, Elmira, New York

by n4csitwo＠bellsouth.net

An International Space Station school contact has been planned with participants at National Soaring Museum, Elmira, New York on 01 Apr. The event is scheduled to begin at approximately 18:34 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and IK1SLD The contact should be audible over Italy and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. The National Soaring Museum sits atop Harris Hill, overlooking Elmira, New York, the "Soaring Capital of America". The National Soaring Museum was established in 1969, and underwent expansions in 1979 and 1989. The Soaring Museum is home to the Soaring Hall of Fame, and the Soaring Society of America's Archives. By collection, the NSM is the largest museum in the world dedicated to motorless flight. In 1972, the New York State Department of Education chartered the Museum as a non-profit educational institution. Its role as an educational institution provides youth with unique experiences to learn about the science and history of aviation. The Museum offers overnight soaring encampments for youth groups, and two summer camps: the Summer Soaring Academy, and Eileen Collins Aerospace Camp (ECAC). The Summer Soaring Academy is in its fourth year, and offers local students a hands-on look at aviation and engineering, capping off the week with a glider ride for all students. The Eileen Collins Aerospace Camp - named for the Elmira native who would become the first woman to command a space shuttle mission - is a weeklong adventure in aviation and space exploration. The week is filled with hands-on activities, trips, and rides in a sailplane and power plane. ECAC is one of the few in the United States that gives students an opportunity to fly in airplanes. This Harris Hill remains an active gliderport, with a strong Junior and Senior program. Several youth who attended this camp have joined the Harris Hill Juniors to become glider and power pilots themselves. Participants will ask as many of the following questions as time allows: 1. What made you want to become an astronaut? 2. Have there been any injuries on board? 3. What's a day in space like? 4. How do you stay stationary on space walks if the ISS is moving? 5. How far can you be from Earth and still talk to Mission Control? 6. Have you ever been on a mission that's gone badly? 7. How does microgravity feel? 8. How fast does the ISS go, and can you feel it moving? 9. Has there been any "unearthly" sightings? 10. What are you studying? 11. Were you scared when you went into space? 12. How do you talk to your family? 13. What courses in school do you have to take to be an astronaut? 14. What does it feel like to enter and exit the atmosphere? 15. Are space walks difficult? 16. Is microgravity difficult to deal with? 17. Do you bring something with you to remind you of home? 18. How long does it take to become an astronaut? 19. How do you control the rocket that takes you to the Space Station? 20. What's the most rewarding thing about being an astronaut? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook. We can be found at Amateur Radio on the International Space Station (ARISS). To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD 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), 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.

Satellite Connection

by Rupert Hamblin

Hi All, Would be grateful for any advice or your thoughts on the following...! Ok, so I have my station virtually completed now. I have the rotator setup correctly and with the LVB Tracker interface unit and SatPC32 now tracking SATs correctly (it appears). I have a 4 ELE (2M) and 9 ELE (70cm) on the rotator. I can receive very good copy of downlinks from quite low passes on both 2M & 70CM, and I have recently had the FT-847 lab repaired and tested on output - which I know are working ok. The problem I have is - whichever satellite i try to work, low pass / high pass, SSB or FM, high power or low power - I am unable to hear my own signal on the downlink and hence so far have no QSO's ....Any suggestions or clues as to what I may be doing wrong or have setup incorrectly...? Would appreciate any clues / tips here ! :-) Cheers RH / G0TKZ
