SSB:
Instead they use what is called Single Side Band or SSB. An AM signal which
you hear, such as from a typical International Broadcaster, is made of a
carrier, that's in essence the signal strength, and on both sides of this is
the modulation, or speech which you hear. Single Side Band on the other hand
only uses modulation on one side of the carrier, hence the name. If the
upper side is used, it's called Upper Side Band, with the lower it's Lower
Side Band. This results in a more efficient transmission, using less
bandwidth and is generally less prone to fading. As a result this is
favoured by those who are sending important messages, such as the military
or civil users mentioned and also the Radio Amateurs who require readable
signals over long distances. However, listening to a SSB broadcast does
require very precise tuning. Your radio may or may not have a SSB
capability. Listening to SSB transmissions on normal AM mode makes the audio
sound distorted and generally incomprehensible. If you own one of the radios
recommended at the beginning of this FAQ, costing at least £100 or 150,
then it more likely has SSB capability. In which case you can enjoy the
whole off-shoot of shortwave listening which is utility station listening.
