INTRODUCTION TO SINGLE SIDEBAND (SSB

)

Many higher-end shortwave radios have special circuitry enabling
SSB, a highly efficient way of electronically processing transmitted
and received signals for two-way communication. Examples of this
are amateur radio (hams), maritime and aeronautical communication.
Either upper side band (USB) or lower side band (LSB) can be used.
Non-voice methods of communication can also be heard, including
CW (Morse code) and RTTY (radio teletype).

Receiving SSB signals is not always easy. Since this is two-way
communications, transmissions are often very short and sporadic. Also,
most two-way communication uses relatively low power, 50 to 1000
watts. The amateur radio operators are easiest to find, Best results
are experienced when using an outdoor shortwave antenna such as a
dipole.

Follow your radio’s instructions on how to engage its SSB feature.
Shown next are some selected frequency ranges on which SSB com-
munications can be found. All frequencies are shown in kilohertz.
