SSB is also known as marine high-frequency single-sideband (HF SSB), a name derived from the frequency range it uses, the HF range of 3 to 30 megahertz (MHz). Medium Frequency (MF) is located below the HF bands at .3 to 3 MHz, while Very High Frequency (as in your VHF radio) is above at 30 to 300 MHz. (See adjacent article Im With the Band.)

In radio communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of modulation used to transmit information, such as an audio signal, by radio waves.A refinement of amplitude modulation, it uses transmitter power and bandwidth more efficiently. Amplitude modulation produces an output signal the bandwidth of which is twice the maximum.
