SHORTWAVE RADIO

 

Hello and welcome back....Shortwave Radio is one of those hobbies that can be started with minimal layout, which means a shortwave radio can cost as little as $100 or it can cost several thousand for a decent rig.

 

I enjoy shortwave mostly because you can hear lots of different things including weather reports from far away places, news services from America (Voice Of America), Australia (ABC), Aircraft from around the world and various Military stations.

The shortwave frequency band is between 3 - 30mhz. Being low in frequency means long distance.
As explained in a web page from radio shack =

  • Shortwave frequencies tend to follow the curvature of the earth, which allows them to bend around the horizon rather than going off into space.
  • Shortwave frequencies can be bounced off of the ionosphere, which also allows the signal to be sent past the horizon.

To recive Shortwave Radio you will need a decent antenna, the best one to use is a "Longwire" antenna which as it sounds, is a length of wire with insulators and a single lead to the radio (see below)... one word of warning, Disconnect from the radio in a thunder storm other wise you way end up with a new perm or worse.
You can also use a telescopic antenna which will give you O.K results. Youtube has some great homemade ideas as well.


 
Jaycar electronics sell several Shortwave Radios (Digitech) but my faviourite brands would be Sangean and Sony, Also Dick Smith sell just one radio being a Sangean ATS-505 ($149).
Andrews Communications ( see Links) sometimes sell used shortwave radios that can save a good deal of money, these radios have been checked to make sure that they work. : )
Alot of high end scanners will do Shortwave as well and E-Bay is always an option.

If anyone knows anywhere else you can buy shortwave rigs let me know and I will add them to the post




There are several websites that have hundreds of frequency's available and I will put the links below, rather than copy and paste, which would not be fair for enthusiasts who spend hundreds of hours putting these pages together.
