Balloons! Space Stations! Aurora!
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
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.
Details on the contest:

See the International Space Station THIS WEEK!
The space station will be visible from much of North America in the evening this week. Spaceweather.com has a very handy calculator that will let you know when and where to look. Just plug in your zip code:

(There is a global version of the calculator for users outside the U.S.)
Let's see how many SolderSmoke readers get to see the ISS this week. Please let me know if you see it.

W4HBK's QRSS Grabber: The Amazing Pensacola Snapper
Now that we are back in the States, W4HBK's grabber is playing a similar role for me. His grabber consistently seems to pull in more sigs than most of the other North American grabbers. The above image is a sample of what you will see when you visit his grabber web page. (I'm also a big fan of the W1BW and VE1VDM grabbers -- thanks guys!)
My signal is the "shark-fin" pattern just a little below the middle of the screen. That's 20 mw to a 50 foot piece of AC line cord about 12 feet off the ground. And it is making the trip from Northern Virginia to Pensacola Florida very consistently. Thanks Bill!
Try taking a look at the Pensacola Snapper and see if you can spot my QRSS signal. My frequency varies from day-to-day (sometimes intentionally!). And lately Bill has occasionally been parking his receiver on 40 meters :-( But most days you will be able to see his 30 meter screen, with my shark fins menacing Pensacola. Please let me know if you see me.
Here is OM HBK and his bio:
Born: 1939, Pensacola, Florida
I was first licensed in 1954 as WN4HBK and upgraded to General in 1955 acquiring the call sign I've used to this day. My dad is responsible for my favorite suffix moniker. the Hot Biscuit Kid. I could really put away my mom's scratch biscuits!
My first station I built myself and consisted of super regenerative RX and a 6L6 TX.from designs in the ARRL Handbook. My dad was a radio mechanic for the Navy and taught me how to read schematics and solder. Later stations consisted of Hallicrafters S-38C, National NC-98, HRO-5 recievers and several Heathkit and Globe Scout transmitters. Boy, those were the days!!
After high school I entered college intending to become an antenna engineer but eventually gravitated towards a degree in Physics. This was pretty cool because it led to a career with NASA where I worked on the Mercury, Gemini, Apollo and Space Shuttle projectsall thanks to my early interest in radio.
Today I'm fully retired and living in Gulf Breeze, FL. just across Pensacola Bay from my hometown. My XYL (Anna) and I enjoy the local beaches in a variety of wayssurf fishing, beachcombing, hiking, painting (her) and photography (me). We are also enjoy gardening and winemaking.
My Amateur Radio interests are CW, DX, contests, antennas and digital modes.
Presently I am experimenting with QRSS and have a 250 milliwatt MEPT station on 10.140 MHzsend me an email if you copy my signal. I now have a grabber to present a spectral display of QRSS activity for other Hams worldwide to watch for their signals http://www.qsl.net/w4hbk/w4hbkgrabber.html

The Hacker-Knacker-Maker Revolution gathers steam...
Anyway, the Hack-Knack-Make revolution continues. This morning I learned that the New York and Philadelphia Hacker-spaces will be featured on NPR's Weekend Edition this Sunday. (I'm jealous -- I want SolderSmoke to somehow get onto NPR. One listener suggested a letter-writing campaign...)
The poster shown above is for a documentary that is being done on all of this. Check it out: http://www.electromagnate.com/

KNACKERS OF THE WORLD UNITE! You have nothing to lose but your warranties!
I find that a successful repair is almost as gratifying as a scratch-built homebrew project, especially if the problem was difficult to diagnose.
So, ifixit comrades: The SolderSmoke collective is with you! Up the Revolution!

"She built her own oscilloscope at age 14." Homebrew Hero: Tatjana Van Vark
When you look at the Enigma-like coding machine, note the cryptological challenge at the bottom. Tatjana won't release the tech details of this project until someone cracks the encrypted Haiku! Go for it!

Homebrew Transistors!
None of those store-bought parts for Jeri Ellsworth! Once again she makes us all look like a bunch of pathetic appliance operators. I like the "harvesting of Germanium" from a 1N34. And I found very interesting her comment about "early hobbyists" cracking open 1N34's and turning them into transistors by adding phosphor-bronze collectors.
This all makes me want to fire up my Fool's Gold crystal radio. WFAX is right down the road...
BTW: I'm very pleased to report that Jeri is currently reading "SolderSmoke -- Global Adventures in Wireless Electronics." I hope she likes it. She definitely has "The Knack."
SolderSmoke Podcast 127 is almost ready.
