[amsat-bb] some videos from 2014 Dayton Hamvention weekend
Hi! I just went through and uploaded the videos I made from last weekend's Dayton Hamvention. First, Paul N8HM working SO-50 on Friday (16 May) morning at 1431 UTC: https://www.youtube.com/watch?v=0-Tz3Q54TDw Michael KD8QBA, part of the MO-76 ($50Sat, Eagle-2) team, was around the AMSAT demonstration station during several passes from his group's satellite. This video was one of those passes, Friday afternoon at 1638 UTC: https://www.youtube.com/watch?v=JZ-yOrGShuw Back to Paul N8HM on the microphone, working AO-7 Friday afternoon at 2013 UTC: https://www.youtube.com/watch?v=nhPceiEpv8U Yes, it was raining hard Friday afternoon, which wiped out the audience watching this pass. This was a difficult pass to work, but Paul (and the rest of us braving the rain) stuck it out. My final video has Paul N8HM working AO-73 on Sunday (18 May 2014) afternoon at 1602 UTC: https://www.youtube.com/watch?v=CaWf_kgpvE8 The weather was much better on Sunday than earlier in the weekend. I know there are other videos on YouTube from the AMSAT station, including one where I'm working SO-50 during the 1345 UTC pass Sunday morning (thanks N8HM): https://www.youtube.com/watch?v=l26-wRO1pcU I have just uploaded my QSOs from this pass, and the other passes I worked on Sunday and Monday (19 May) at the Hamvention and other locations, to the Logbook of the World. The QSOs I made on Thursday (15 May) through Saturday have already been uploaded to LOTW. Paul N8HM uploaded a video of his Kenwood TH-D7 HT, showing the APRS traffic on 144.390 MHz on the Thursday (15 May) night in the Dayton area before the start of the Hamvention: https://www.youtube.com/watch?v=O4LtHWIjlNs This video is a perfect example of how the 144.390 MHz frequency was, during the entire weekend. Day or night, signals were being transmitted on that frequency non-stop. Edward Raybould N8OIF posted a couple of videos as well. First, a video where Keith W5IU is at the radio during an HO-68 pass to demonstrate the Doppler effect: https://www.youtube.com/watch?v=WzCx0Uap8Wo Keith W5IU is working AO-73 on Saturday (17 May 2014): https://www.youtube.com/watch?v=MwteyjKhGxw There may be others up there now, and more coming soon - including (I hope) videos from the AMSAT Forum on Saturday. :-) 73!

[amsat-bb] WD9EWK VA7EWK/3 QSOs from Hamvention weekend
Hi! I just finished updating my satellite log for my operating over the past few days in Ohio and other locations. I operated from the following locations during my trip (dates are using UTC time): Tilbury, Ontario (grid EN82sg), 15 May Indiana/Ohio state line (grid EM79ot), 17 and 19 May Englewood, Ohio (grid EM79uu), 17 May Trotwood, Ohio (Hamvention - grid EM79ut) - 18 May New Richmond, Ohio (grid EM78ux) - 18 May Hamersville, Ohio (grids EM78xw and EM88aw) - 18 and 19 May Miamisburg, Ohio (grid EM79vp) - 19 May I operated as WD9EWK for all locations except my first stop in Ontario, where I operated as VA7EWK/3. All of these QSOs are now in Logbook of the World, and I would be happy to send QSL cards for any QSOs made with WD9EWK or VA7EWK/3. Please e-mail me the QSO details, and - if you're in the log - I will send out the card(s). No need to first send me QSL cards or SASEs to get my card(s). If you use Logbook of the World and want to see QSLs for both sides of the Indiana/Ohio state line, please upload two QSO records to represent that QSO on each side of the state line. Put the same information in each record, except make the time different in each QSO record by at least one minute. Without this adjustment, one of the QSO records will replace the other, when LOTW sees two QSO records for the same date and time with the same station. LOTW can handle up to 4 grid locators in a single QSO record, but is not capable of handling multiple states (or provinces, counties, and countries) in a single QSO record. I have uploaded two QSO records to LOTW for each QSO I made at the state line, ensuring the QSO time in the record for each side of the state line differs by one minute. Some have also already uploaded two QSO records for each QSO completed with WD9EWK at the state line, and have received credit for QSOs with both Wayne County in Indiana and Preble County in Ohio (the two counties that come together at that point on the state line, near the I-70/US-40 interchange at Richmond IN). Please e-mail me directly if you worked me at this location, and need further assistance in seeing confirmations for both sides of the state line. 73!

[amsat-bb] Space Hackers Prepare to Reboot 35-Year-Old Spacecraft (Long)
This long piece comes from IEEE Spectrum http://spectrum.ieee.org/tech-talk/aerospace/satellites/space-hackers-prepare-to-reboot-35-year-old-spacecraft AMSAT-DL is mentioned throughout this piece. Dennis Wingo is KD4ETA. He has a blog http://denniswingo.wordpress.com/ Enjoy! 73, Eric W3DQ Space Hackers Prepare to Reboot 35-Year-Old Spacecraft By Rachel Courtland Posted 15 May 2014 | 17:00 GMT Early next week, a team of volunteers will use the Arecibo Observatory in Puerto Rico to see if they can make contact with a spacecraft that hasn't fired its thrusters since 1987. If all goes well, the effort could bring the 35-year-old spacecraft, the International Sun-Earth Explorer 3http://solarsystem.nasa.gov/missions/profile.cfm?MCode=ISEEICE (ISEE-3), back into position near the Earth, where it could once again study the effect of solar weather on Earth's magnetosphere. It will be a race against time. ISEE-3, which is transmitting two carrier signals, only came into hearing range a couple of months agohttp://amsat-uk.org/2014/03/09/radio-amateurs-receive-nasa-isee-3ice-spacecraft/. Dennis Wingo, CEO of California-based Skycorp Incorporatedhttp://www.skycorpinc.com/Skycorp/Home.html, and his colleagues reckon ISEE-3 still has enough fuel to make it back to its original orbit at the Lagrangian point L1http://www.esa.int/Our_Activities/Operations/What_are_Lagrange_points, at a spot between the sun and the Earth where a spacecraft can stay in sync with Earth's orbit. But to make it, Wingo says, the spacecraft must be commanded to fire its thrusters by mid-June. And that's far easier said than done. NASA no longer has the hardware to communicate with the ISEE-3. So in April, Wingo and Keith Cowing, a former NASA employee and editor of the websites NASAWatch http://nasawatch.com/and SpaceRef http://www.spaceref.com/, started a (still-running) crowdfunding campaign http://www.rockethub.com/42228 on RocketHub to develop what they need to communicate and control the spacecraft: signal modulators and demodulators, transmitters, and a software-based mission control console to monitor the spacecraft's propulsion and attitude control systems. Building all of this even 10 years ago would have been impossible, Wingo says. But with the advance of embedded systems technology, the team can construct radio components in software and debug them on aggressive timescales without breaking the bank. With no time to wait, the team has already purchased software-defined radio peripherals https://www.ettus.com/product/details/UN210-KIT built by Ettus Research, which can be used to implement modulator and demodulator programs that would once have had to be built in hardware. Ettus has volunteered to help with the programming, and one member of the company will join Wingo in Arecibo. They'll set to work there on 19 May, using a 400-watt transmitter shipped in from Germany to try to make contact with the spacecraft. One of the first things they'll do is command the spacecraft into engineering telemetry mode, where it's hoped it will send signals that will give the team a better sense of the condition of the spacecraft. Assuming ISEE-3 is in good health, Wingo says, the next big challenge will be to assess its trajectory for a proper thruster firing. The team will use transmitters and antennas at Arecibo, Morehead State University in Kentucky, the Bochum Observatory in Germany, and, potentially, the Allen Telescope Array in California, to ping the spacecraft. The hope is that the team will not only be able to measure Doppler shifts in frequency to get a fix on the spacecraft's velocity, but also signal time of flight to triangulate its position. This will be difficult, so even though the project met its fundraising goal on Wednesday, Wingo says the team is still seeking funds in case they must pay NASA to do the ranging for them. The reboot project schedule is aggressive. We're in panic mode every day, Wingo says. But I think we have a reasonable chance of making this work if the spacecraft is healthy. If the effort succeeds, it won't be the first time that ISEE-3 has had a change of course. After its launch in 1978, the spacecraft was repurposed (and renamed the International Cometary Explorer) in the early 1980s to chase Halley's Comet, then tasked again with performing solar observations in 1991 before mission cancellation in 1997. Although more capable spacecraft have since launched, recapturing ISEE-3 could give researchers access to a consistent set of instruments with which to compare old measurements of the Earth environment, Wingo says. The peak of this solar cycle is about half as activehttp://www.solen.info/solar/images/comparison_recent_cycles.pngas the peak of solar cycle 21, which ISEE-3 observed. [We can use the] same set of instruments to look and see what the differences are in Earth's magnetosphere, Wingo says. Most of ISEE-3's science instruments could still be in

[amsat-bb] Wheeler Says FCC Needs More Engineers
From RadioWorld Enjoy! 73, Eric W3DQW - Wheeler Says FCC Needs More Engineers by Leslie Stimson on 05.20.2014 FCC Chairman Tom Wheeler believes the FCC could use more engineers -- and economists. He said so during testimony today before the House Subcommittee on Communications and Technology. It's been six months since Wheeler has faced lawmakers; he was the sole person to testify during an FCC oversight hearing. The engineer comment came during an exchange between the chairman and Vermont Democrat Rep. Peter Welch, who simply asked what the commission needs to do its job. Our IT infrastructure is worthy of being in the Smithsonian, Wheeler replied, noting the agency has computers that have known risks. The commission can't provide an easy way for the public or industry to accomplish some tasks online, said the chairman, because our IT system isn't up to it. That's when he said: We do need more engineers, and economists, too. His definition of engineer includes IT as it does at the station level these days as well. In previous testimony about the latest budget request, Wheeler told lawmakers the agency has more than 200 relic IT systems that are costing the agency more to service than they would to replace over the long term. The commission asked for a total of 1,790 Full Time Equivalent positions for FY 2015, which includes an additional 10 such positions for Information Technology programming. Broadcasters would like the agency to have more technology-related personnel too, believing that would make some decision-making affecting the industry to go more smoothly. Discussion of the agency's recent open Internet proposal dominated much of the discussion. -- ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Re: [amsat-bb] Wheeler Says FCC Needs More Engineers
Is this part of the same story about how they need like people that are cyber geeks to help in the cyber crimes and stuff like that world. But they can not find enough to fill the open positions because of their rule of not hiring anyone that has smoked pot within the past 3 years? Akll the applying cybergeeks when they have been getting to that part of the applications have walked out.
