Tone
The T stands for "Tone". Tone is used only used in Morse code and digital transmissions and is therefore omitted during voice operations. With modern transmitter technology, imperfections in the quality of the transmitter modulation that can be detected by humans are rare. Tone is measured on a scale of 1 to 9.

Famous quotes containing the word tone:
“It hurts me to hear the tone in which the poor are condemned as “shiftless,” or “having a pauper spirit,” just as it would if a crowd mocked at a child for its weakness, or laughed at a lame man because he could not run, or a blind man because he stumbled.”
—Albion Fellows Bacon (1865–1933)
“Self-confidence is apt to address itself to an imaginary dullness in others; as people who are well off speak in a cajoling tone to the poor.”
—George Eliot [Mary Ann (or Marian)
“...I ... believe that words can help us move or keep us paralyzed, and that our choices of language and verbal tone have something—a great deal—to do with how we live our lives and whom we end up speaking with and hearing; and that we can deflect words, by trivialization, of course, but also by ritualized respect, or we can let them enter our souls and mix with the juices of our minds.”
—Adrienne Rich (b. 1929)
