Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide, and can be received thousands of kilometres from their source.</blockquote><ul><li><ahref=https://en.wikipedia.org/wiki/Radio_atmospheric_signal>Wikipedia</a></ul><h2id=Why_catch_them?>Why catch them?</h2><p><ahr
