Transmission Modes
Transmissions on 2182 kHz commonly use single-sideband modulation (SSB) (upper sideband only), however amplitude modulation (AM) and some variants such as vestigial sideband are still in use, mainly by vessels with older equipment and by some coastal stations in an attempt to ensure compatibility with older and less sophisticated receivers.

Famous quotes containing the word modes:
“Of the modes of persuasion furnished by the spoken word there are three kinds. The first kind depends on the personal character of the speaker; the second on putting the audience into a certain frame of mind; the third on the proof, provided by the words of the speech itself.”
—Aristotle (384–323 B.C.)
