GETTING STARTED WITH SINGLE SIDEBAND
(SSB)
Many high-end shortwave radios have a feature called
SSB, a highly efficient way of electronically processing
transmitted and received signals for two-way commu-
nication. Examples of this are amateur radio (hams),
maritime and aeronautical communication. Either
upper side band (USB) or lower side band (LSB) can be
used.

Receiving SSB signals is not always easy. Since this is
two-way communications, transmissions are often very
short and sporadic. Also, most two-way communica-

tions uses relatively low power, 50 to 1000 watts. The
amateur radio operators are easiest to find; the others
can be very difficult. Best results are experienced when
using an outdoor shortwave antenna such as a dipole.
Finding SSB signals can be like seeking a “needle in a
haystack”, so be patient! The easiest place to find SSB
communications is at night in the amateur band
shown below at 3650-4000 kHz. Follow your radio’s
instructions on how to engage its SSB feature. Below
are some selected frequency ranges on which SSB
communications can be found. All frequencies are
shown in kilohertz.
