[3] What do I need to know to start using one?

   All you need to know to begin are the same techniques for using an
   identical FM radio, while putting off learning shortwave concepts &
   jargon indefinitely. A special set of skills is not mandatory, yet
   your listening enjoyment will increase as you gain experience and
   develop relevant skills, such as: keeping up on local & non-local
   events which may affect broadcasts (e.g. strikes & ionospheric storms
   causing stations to 'disappear'); troubleshooting & maintaining your
   radio; and using various types of antennas (e.g. loop antennas for
   nulling out local interfering stations or noise sources).
