Getting ready for JOTA 2013
Hamshpere is an excellent opportunity to pratice amateur radio, and since I don't have a real ham radio station, I can pratice and be prepared for the Jamboree on the air.
This year I will be on board of a new scout station, the callsign is CR5NMV.

Solar storm... propagation low!

(CNN) -- Attention, Earthlings: The sun is spewing plasma toward you, and the results could be beautiful.
Stargazers looking to the sky late Tuesday night and early Wednesday morning could see northern lights, or aurorae. According to the Harvard-Smithsonian Center for Astrophysics, the potential light show started Sunday, when the sun's surface erupted and hurled tons of ionized atoms -- or plasma -- into space.
"This eruption is directed right at us, and is expected to get here early in the day on August 4th," said astronomer Leon Golub of the Harvard-Smithsonian Center for Astrophysics (CfA). "It's the first major Earth-directed eruption in quite some time."
When such an expulsion reaches Earth, it interacts with the planet's magnetic field and can create a geomagnetic storm, the CfA said. Solar particles stream down the field lines toward Earth's poles. Those particles crash with atoms of nitrogen and oxygen in the atmosphere, which then glow like little neon signs.
Sky watchers in the northern U.S. and other countries should look toward the north late Tuesday or early Wednesday for rippling "curtains" of green and red light, the CfA said.

A VHF/UHF Nagoya Antenna and more...
The new acquisiton for my shack...
While I'm still waiting for some free time to build the Yagi antenna, this one will do! Pretty okay so far!

Super Magnet Antenna Dual Band
UT-108UV Nagoya Antenna
Specifications:
Frequency: 144/430MHz
Gain: 3.0db
Max power: 20 Watts
V.S.W.R: Less 1.5
Impedance: 50 OHM
Connector: BNC
Magnet size: 31 mm
Length: 510 mm
Coaxial Cable: RG-174 A/U 3M
Weight: 113g
And a very nice and handy micro/speaker from Jetfon, the JR-4009, will complete the pack I bought last Sunday at ARVM's Radio Fair!

A 2m Backpaker Yagi Antenna - my next challenge
This is a lightweight antenna designed by KD5IVP. It's simple to build and lightweight. It is for use on the 2 meter band. This video is the explanation on how to build it. It will be my next challenge...

52nd JOTA is coming!
World Scouting's communication theme for this year is environment, given our work and the worldwide focus on the United Nations Framework Convention on Climate Change Conference (COP 15) in Copenhagen 7 - 18 December. Therefore the "C3" is an excellent opportunity to show to the world the efforts of millions of Scouts to protect the environment and take positive action against climate change. JOTA is a real testimony to the international dimension of Scouting, where young people not only learn about new technologies, they can understand that there are millions of Scouts all over the world sharing the same vision: creating a better world!The radio and Internet discussions that will take place during the JOTA will contribute to enhancing the participants' awareness of environmental issues.
