Single sideband transmission is a form of amplitude modulation but in effect filters the result of modulation.

This process also occurs naturally if a radio receiver is tuned to a single sideband transmission but set to decode the wrong sideband.
3.
The audio data is usually combined with up to 7 bit / s of forward error correction data, producing a total RF bandwidth of approximately 2, 250 Hz ( compared to 2, 700 3, 000 Hz for an analogue single sideband transmission ).

These stations broadcast navigation and marine safety messages through several means, including Navigational Telex [ NAVTEX ] transmissions on 518 kHz; facsimile transmissions of National Weather Service charts; single sideband transmissions; and Simplex Teletype Over Radio SITOR narrow-band direct-printing broadcasts.
