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 makes me hate accepting things that are probable when they are held up before me as infallibly true. I prefer these words which tone down and modify the hastiness of our propositions: “Perhaps, In some sort, Some, They say, I think,” and the like.”
—Michel de Montaigne (1533–1592)
“If the oarsmen of a fast-moving ship suddenly cease to row, the suspension of the driving force of the oars doesn’t prevent the vessel from continuing to move on its course. And with a speech it is much the same. After he has finished reciting the document, the speaker will still be able to maintain the same tone without a break, borrowing its momentum and impulse from the passage he has just read out.”
—Marcus Tullius Cicero (106–43 B.C)
“...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)
