Jupiter's Moons Utility

"Sky and Telescope" has a nice collection of on-line astronomy utilities. One of my favorites displays the positions of Jupiter's Galilean moons. It also gives you some nice heads up on the transit and eclipses of the moons. Its fun to play with the "+10 minute" button and see how they move around. The view you see above is fairly close to what I see through my telescope (but Jupiter's stripes are not quite so pronounced). You can get the utility for free -- you just have to fill out a registration form.

N8ZRY's Homebrew SSB Rig

A while back we had post about amateur RADAR. The wizard behind that project was Greg, N8ZRY. (I liked his quote: "Old radars do not die... they simply phase array.") Greg's latest project is the 20 meter SSB rig pictured above. It was recently featured on the Make blog.
Check it out here. Be sure to look at the YouTube video. Nice job Greg!

The Secrets of Success of the Pensacola Snapper

Bill, W4HBK, sent a nice note in response to my blog post describing his MEPT QRSS grabber receive station. You can see the peninsula he describes above.
Bill writes:
Wow, what a pleasant surprise. I do remember pulling you out of the noise while you were in Italy and enjoying your reports from there. If there is a secret to my grabber it is a combination of environment and antenna. My neighborhood has underground utilities and is well away from town on a peninsula which juts out into Pensacola Bay. My main antenna is an inverted V 60' up in a tall pine tree for good low angle response and rejection of vertically polarized noise. About the only noise I hear is sferics. Thanks for the article. 73 bill w4hbk

Listen up for METEORS!

The folks at spaceweather.com have come up with something really cool. We are now in the final phases of the annual Leonids meteor shower. I can't see many meteors through my light-polluted skies (plus its COLD out there), but Spaceweather Radio has come to the rescue. They currently have on-line the audio feed from a receive station tuned to the freq of the The Air Force Space Surveillance Radar. It transmits 24/7 on 216.98 MHz. It is reported to be on of the most powerful transmitters in the world. You can hear the "pings" caused by the reflections of meteors. I've heard several as I typed this post! Be sure to visit the "how we do this page." I appears that there is ham running the receive station.

Occasionally I hear a longer tone. Could that be the reflection of a Low Earth Orbit satellite going over the site?

Balloons! Space Stations! Aurora!

My in-box seemed to have an outer space theme today. First, from Guanajuato, Mexico comes word that the radio club there is planning a second edge-of-space balloon launch. SARSEM ICARUS II is scheduled to go up on 20 November carrying a VHF/UHF repeater. SARSEM ICARUS I was obviously a big success. Check out the picture it took from 29000 meters up (above). Thanks Roberto!

A couple days ago we noted that the International Space Station would be visible over N. America this week. So far we have only one report of a sighting: Jim, AL7RV saw it from Mississippi. This morning Yahoo carried some pictures taken from the crew's cupola. This one shows some territory dear to our hearts!

Finally, spaceweather.com carried this beautiful aurora shot from Tromso, Norway. It was taken by Ole Christian Salomonsen on November 14. Spaceweather notes that "a solar wind stream has been buffeting the earth's magnetic field." This probably explains why Maria and I could hear very few stations on 75 meters last evening. And 75 seemed totally dead yesterday morning.

MAKE'S "Do More With Less" Contest

This from the MAKE blog this morning:

To promote the release of the Windows Phone 7, Microsoft is partnering with various websites, including MAKE, to give away a Windows Phone 7 to each site's readership. To be eligible, all you have to do is post a comment on the theme of "Do more with less" ...

Wow! This contest seems to be MADE for the G-QRP gang! (What is it? "It is vain to use more..." Something like that!) I think G3RJV could win this one!

This is all related to a quote from Buckminster Fuller, hence the image of the very cool stamp.
