[amsat-bb] NO EJECTION MASS Propulsion
It doesn't violate any laws of physics if you are expending power from photovoltaics to propel your spacecraft. For example, you could push against the Earth's magnetic field to get a satellite into a higher orbit. This article seems to confirm this model, although they don't know what they are pushing against: http://www.wired.co.uk/news/archive/2014-07/31/nasa-validates-impossible-space-drive I agree that this is probably nonsense, but maybe it isn't. ___ Sent via AMSAT-BB@amsat.org.

It's either fodder for the conspiracy theorists or it'll win a Noble prize.

[amsat-bb] Rosetta probe has rendezvoused with comet
http://www.dailymail.co.uk/sciencetech/article-2715387/Rosettas-best-view-Esa-releases-incredible-images-comet-just-620-miles-away-spacecraft-closes-in.html The space probe has passed within 1,000 kilometers of the comet and is maneuvering to match velocity. The space probe took an amazing photo. (Ugliest looking comet that I have ever seen!) The space probe will send a lander to the comet's surface. (Next year, maybe?) Unfortunately, the European Space Agency is not as open with their data as the American space agency is. They let their people study the photos first before they release them to the public. ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Running dual IC706MKII-G radios
As a follow-up to this thread, I would like to thank all who replied to my questions and helped me along the way. By following the instructions given, I now have both Icom’s running together with SatPC32…..how sweet Sure beats using the ‘ol overlay plotter…wasn’t it an Oscarlator ? Thanks again and it’s time to finish my Satellite station with some antennas (cp) and get on the air ;0) I’ve already completed the WRAPS-II az/el rotator system. 73 Tom W4TMW ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Perseid Pings on the Internet
The Perseid meteor shower peak is predicted to occur between August 11 to 13. There are a few pre-peak pings already audible. The activity should increase over the next several days. Web streaming of the Perseid is on-line at: http://spaceweatherradio.com/ Quoting from their web page here is how they do it now: The US Air Force Space Surveillance Radar has been shut down, but we're still recording meteor echoes. How do we do it? Radio engineer Stan Nelson uses a Yagi antenna in New Mexico to detect 54 MHz TV signals reflected from meteor trails. When a meteor passes over his observatory--ping!--there is an echo. -- 73 de JoAnne K9JKM k9...@amsat.org Editor, AMSAT Journal ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Reception of UKube-1 FUNcube-2 Beacon
Many stations, who have their FUNcube Dongle SDR setup to automatically receive telemetry signals from FUNcube-1, will have noticed that they are now also seeing the telemetry from the FUNcube-2 sub-system which is flying on-board the UKube-1 CubeSat. This is part of the commissioning program for UKube-1 which is presently underway. http://amsat-uk.org/2014/08/06/reception-of-ukube-1-funcube-2-beacon-on-funcube-dongle-sdr/ Also on the AMSAT-UK website AMSAT to use FundRazr Crowdfunding http://amsat-uk.org/2014/08/05/amsat-to-use-fundrazr-crowdfunding/ UKHAS Conference Greenwich, London on Saturday, August 16 There is an impressive line-up of radio amateurs giving presentations at this event.

[amsat-bb] Cross Country SDR Sentry 10
http://www.crosscountrywireless.net/sentry.html If true, this would provide the first SDR with output on 6 Meters, 2 Meters, 222, 432, and 1.2 GHz. This would be a real game-changer for VHF weak signal operators, and provide enough drive for most amps.

Re: [amsat-bb] AO-73 tonight at 02:58Z
Worked W5PFG and CO6CBF on the pass. Satellite sounded great as it always does. With my Arrow and 2 FT-817s, I was able to locate my downlink with the satellite at about 1.5 degrees of elevation. My signal was plenty loud at about 2.5 degrees. 73, Paul, N8HM On Wed, Aug 6, 2014 at 8:53 PM, Paul Stoetzer n...@arrl.net wrote: Good evening, I will be on AO-73 tonight at around 02:58Z, calling CQ at around 145.965 MHz. These passes usually don't have much, if any, activity and I'd like to drum up a bit more. The satellite will enter sunlight at 03:05:45, giving about 7 minutes of transponder time here in Washington, DC. I will be operating off a south facing balcony, so I will probably lose the satellite about 30 seconds before the transponder shuts off. Tips for working AO-73: -Do not use computer control, the transponder frequencies are not stable and this will only result in frustration. Besides, manual Doppler control is much more fun than letting the computer do all the work! -I usually start a pass by trying to find myself come into the top edge of the passband (145.970 MHz). To do this, I usually start transmitting around 435.130 MHz and tuning up slowly until I can hear myself enter the passband. Then I can move around the transponder easily. Remember to tune your uplink to maintain an constant downlink frequency (the opposite of FO-29). -Keep power output down. The transponder has a very sensitive receiver and a very active AGC circuit. Excessive uplink power will not make your signal louder - it will only reduce that available for others on the transponder. With a clear view of the horizon, 5 watts to an Arrow or Elk is plenty for horizon to horizon coverage. Very slightly more might be necessary if you are beaming through trees or other obstructions, but try to keep power to 25-40 watts ERP. Hope to hear you on this evening! 73, Paul Stoetzer, N8HM Washington, DC ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
