Homebrew Solar Panels
I hate to tell you, but all you guys who are using STORE-BOUGHT solar panels are a bunch of APPLIANCE OPERATORS. Time to roll your own, and REALLY make your own electricity.
Woody, KF4TQJ, sent me this interesting link on how to make your own solar panel:

Before you get carried away by homebrew enthusiasm, scroll down a bit on that page and check out the cost estimates for large scale application of this technology.

See if you can see my signal 10140055 Hz
If Italy is in daylight, you should be able to see my 50 milliwatt FSK signal on one of the European on-line grabbers.
IK0VVE has a nice grabber aggregator site that includes a sun clock. Here it is:
http://www.ik0vve.net/mept6.aspx
Just see if the sun is shining here, then scroll down and take a look at either PA1SBD's site or ON5EX's. Sometimes I can also be seen on I2NDT's.
You should see my signal around 10140055 Hz. It looks kind of like a square wave. Read the Morse along the bottom (my FSK is upside down).
For extra credit, see if you can see Paolo's solar beacon. It too looks like a square wave, but with no Morse. He's running 2.5 milliwatts.
Please let me know if you succeed in seeing our sigs.

Arduino -- Italian Open Source Hardware
Scott Haley in Tulsa alerted me to this very interesting article in Wired magazine. How do you say Knack in Italian? Check it out: Wired article on Arduino

Aliens on 80 meters!
Graham, G3ZOD, was looking at the 80 meter band using the on-line SDR receiver in the Netherlands (http://websdr.ewi.utwente.nl) This is what appeared on the screen. Looks like you can work some real DX on 80 these days. The big issue will, of course, be DXCC credit. And I imagine getting a QSL card might be a bit tricky.

The Flea: Minimalist QRP from Catalonia
Here is a really interesting little rig from Joan, Ea3FXF, and Eduardo, EA3GHS. They have a very nice web site with more info, including SPICE simulation files and SPICE waveform results.
