[amsat-bb] NO EJECTION MASS Propulsion

2014-08-06 Thread Mike Lemons
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:

I agree that this is probably nonsense, but maybe it isn't.

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

[amsat-bb] Rosetta probe has rendezvoused with comet

2014-08-06 Thread Mike Lemons

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.

2014-08-06 Thread Tom Warren

  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

[amsat-bb] Perseid Pings on the Internet

2014-08-06 Thread JoAnne Maenpaa
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.

[amsat-bb] Reception of UKube-1 FUNcube-2 Beacon

2014-08-06 Thread M5AKA
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.

[amsat-bb] Cross Country SDR Sentry 10

2014-08-06 Thread Les Rayburn

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. Can't 
wait to learn more about this product.

Did you look at the Blade RF?

With available downconverter and full duplex! It is already a game changer
and being used.

Also, the HackRF is shipping now.

Re: [amsat-bb] AO-73 tonight at 02:58Z

2014-08-06 Thread Paul Stoetzer
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.

 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
