SSB (Single Sideband) is a type of amplitude modulation used in radio communications. It allows for more efficient transmission of signals by eliminating the carrier wave and one of the sidebands, which reduces bandwidth and improves clarity. SSB is commonly used in amateur radio, aviation, and marine communications. In SSB, the audio signal is converted into a radio frequency signal, which can be transmitted over long distances. This method is particularly effective for long-range communication, as it minimizes interference and allows for clearer reception. SSB is often preferred for its ability to maintain signal quality even in challenging conditions.
