It may not look like much, but it took a lot of effort to put together. The cables run down into the cellar (passing the signal through an amplifier and filter on the way) where I have an old PC set up ready to process the audio signal from a frequency scanner. So far, I'm only missing the audio cable to join up the two halves of the system!
The idea is to detect meteors using the forward scatter technique. This means we use a receiver to listen for echoes caused by radio signals bouncing off the ionised trails left by meteors when they fly through the upper atmosphere. We are listening to a TV signal transmitted from southern Spain, a transmitter we normally can't hear because it is over the horizon. When a meteor causes an ionised trail in the atmosphere, these radio signals bounce off them, like ordinary light from a mirror, and we can pick up the reflected signal.
There are lots of people doing this around the World, some of them you can find on the web. When the audio connection on this sytem is in place, we should have spectra from the system live on the web as well.
