Tuning in to the Universe Detecting radio signals from other planets

Detecting radio signals from other planets is not difficult to achieve. All you need is a little bit of wire a few pieces of timber and an old radio receiver that has access to short wave. Sure it is not as sophisticated as the professionals radio telescopes but it is a great place to start.
Radio waves are ubiquitous the universe is full of radio energy. Our own planet produces radio waves that are unique to this planet. There is however a lot of manmade radio and television waves being broadcasted over the last 80 years some of these radio waves have traversed our galaxy imagine some alien living on a distant solar system watching “I love Lucy”.
We don’t need to live on a distant plane to pick up radio signals the sun produces enormous amount of radio wave that sound like “hissing rain”. Planet Jupiter is a powerful radio source that produces vast amounts of radio energy that we can pick up here on earth. Shortwave radio signals from Jupiter is not a sign of extraterrestrial intelligence the radio emissions are generated naturally by plasma instabilities in Jupiter's magnetosphere.
Jupiter's magnetic poles sometimes act like a powerful radio laser. The radiation can be so intense that Jupiter frequently surpasses the Sun as a radio source at amateur radio wavelengths.
I have provided a Podcast with sounds from the Sun Moon and Jupiter you can download it from this link

The Galilean Moon Io is the most active volcanic body in the Solar System, Io produces radio waves. Io passes through Jupiter's magnetic field a huge electrical current flows between Io and Jupiter. Carrying about 2 trillion watts of power, it's the largest DC electrical connection in the solar system. listeners can pick up Jupiter’sradio bursts in the shortwave bands between 15 and 40 MHz.

I usually compare signals that I have on database and calculate the differences in amplitude and background noise.
