SSB or Single Sideband is a form of radio signal modulation. In SSB transmitters, the carrier and one sideband are removed before the signal is amplified. Either the upper sideband (USB) or lower sideband (LSB) of the original amplitude modulation signal is transmitted.
SSB is a much more efficient mode than amplitude modulation since all of the transmitter's power goes into transmitting useful intelligence.
