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.
