Uses include every common amateur modulation : morse code, single sideband modulation, frequency modulation, amplitude modulation, and a variety of digital modes such as radioteletype, slow-scan television, and packet radio.

Phase noise can be measured and expressed as single sideband or double sideband values, but as noted earlier, the IEEE has adopted the definition as one-half of the double sideband PSD.
23.
Most use single sideband voice ( SSB ), which uses less bandwidth than AM . On an AM radio SSB sounds like ducks quacking, or the adults in a Charlie Brown cartoon.
24.
Single sideband audio transmission has been popular among amateur radio operators in North America attempting to establish contact with other stations during meteor showers without planning a schedule in advance with the other station.
25.
Single sideband is nevertheless used widely in amateur radio and other voice communications both due to its power efficiency and bandwidth efficiency ( cutting the RF bandwidth in half compared to standard AM ).
26.
L-carrier systems were loaded by multiplexing and supermultiplexing single sideband channels, using the long-standard 12 channel voice " group " produced by Type A channel banks, occupying a frequency spectrum between 60 and 108 kHz.
27.
Forbes has spent " the equivalent of Rwanda's national debt, " wrote Ron Williams in a burst of hyperbole in The Wilmington News Journal, for commercials " on radio, television, cable, walkie-talkie, shortwave, single sideband, ship-to-shore and Morse code ."
28.
The end of the war brought a tremendous expansion of amateur radio as large amounts of war surplus equipment was available, many recently trained operators became active, and experiments began in such newly developed modes as single sideband and microwaves.
29.
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.

The few dozen sailboats that lie here at anchor boast aluminum masts that fairly bristle with electronic sensors _ VHF radio, single sideband, TV, Loran, GPS, radar, anemometer _ all to aid and protect the humanity on the decks below.
