BASIC COMMUNICATING
SSB TRANSMISSION
SSB is now the most commonly-used mode on the HF
Amateur bands. Compared with other voice modes,
SSB requires a narrow bandwidth for communications.
SSB also allows long distance communication with
minimum transmit power. These reasons, combined
with the fact that modern Amateur transceivers deliver
reasonably good audio quality, make SSB the mode
that most prefer on HF.
