SSB (Single Sideband)

Single Sideband (SSB) is a method of modulating radio signals to transmit audio, like voice or music. Unlike traditional amplitude modulation (AM), which sends multiple frequencies, SSB transmits only one sideband—either the upper or lower part of the signal. This makes SSB more efficient, using less power and bandwidth, which improves clarity and range. It is widely used in marine, aviation, and amateur radio communications, allowing users to communicate over long distances with less interference and greater clarity. SSB technology is essential for effective long-range radio communication.
