SSB

SSB (or Single Sideband modulation) is a way of transmitting via radio using only one of the AM sidebands, (the main carrier band and the other sideband having been removed). Its advantage is that all the energy used to transmit is concentrated in this single waveband; long distances can therefore be covered and signals can be clearly received. SSB is therefore ideal for maritime, military, aeronautical and amateur radio uses.
