Shortwave Radio

The bands known as Shortwave are those from about 3 Mhz to 30 Mhz (3000 Khz to 30,000Khz). Over thirty years ago when I started listening the bands were chock full of international broadcasters. Most of the broadcasters had programmes in various languages and I regularly listened to the english services of Radio Sweden, Radio Moscow and the BBC world service. Back then most nations had some form of international service on the Shortwave band. Radio Moscow was very interesting during the final days of the Soviet Union.

Part of the fun of Shorwave is tuning around the dial and seeing what stations you could pick up. You have to tune very slowly and carefully to avoid skipping over something interesting. Over the years I've heard Australia, Japan, China, America, India, Belgium, Germany and many other places. These days a lot of these services are delivered online via the internet, but there is still plenty worth listening to though. Recently I have heard interesting programmes on Radio Romania, The Voice of China and NHK-World Japan.

There are a few ordinary radios which cover the Shortwave bands, but better results can be found with a radio that has been designed for Shortwave listening. The obvious problem with an ordinary radio is that of fine tuning and selectivity, that means the ability to pick out an individual signal is not as good.

You can listen to the radio amateurs on Shortwave too, they call this band HF which means high frequency. A lot of 'Ham' transmissions are in a transmission mode called Single Sideband which is a special form of transmitting which alows the signal to take up less space on the tuning dial. Normally you need a shortwave radio equipped with upper and lower sideband to hear these.
