What is a radio teaser?

What is the difference between radio waves emitted by radio stations and radio waves emitted by solar flares?

• What causes radio waves given off by radio stations to stop being received by your radio after you cross a particular distance, but radio waves from solar flares can be received from millions of miles away? Or is it a question of how powerful the receiving radio is?

• Answer:

  The Sun is more powerful The Sun's signals are unmodulated Some of the interference the Sun generates are caused by its interactions with Earth's magnetic field & ionosphere Man made signals come various forms of modulation and power levels. Different parts of the spectrum have different range capabilities. And power level of the transmitter affects range as well. Each nation considers power level in licensing transmitters so as not to create interference issues .
