(3) If no confusion exists as to which operators are on the radio net, no call
signs need be used.
d. To avoid confusion and errors during voice transmission, special techniques
have been developed for pronouncing letters and numerals. These special techniques
resulted in the phonetic alphabet and phonetic numerals.
(1) The phonetic alphabet is used by the operator to spell difficult words and
thereby prevent misunderstanding on the part of the receiving operator.
(2) The phonetic alphabet is also used for the transmission of messages.
For example, the cipher group CMVVX is spoken "CHARLIE MIKE VICTOR VICTOR
(3) Numbers are spoken digit by digit, except that exact multiples of
thousands may be spoken as such. For example, 84 is "AIT FOW ER," 2,500 is "TOO
FIFE ZE RO ZE RO," and 16,000 is "WUN SIX TOUSAND."
(4) The date-time group is always spoken digit by digit, followed by the time
zone indication. For example, 291205Z is "TOO NIN-ER WUN TOO ZE-RO FIFE ZOO-
(5) Map coordinates and call sign suffixes also are spoken digit by digit. To
keep voice transmission as short and clear as possible, radio operators use procedure
words (prowords) to take the place of long sentences.
e. Paragraph 8-7c(2) give an example of a call sign. If this was the call sign of
your station, you would identify yourself using prowords and phonetics as follows: "This
is al-fah too dell-tah too ait." If abbreviated call signs were being used, you would say,
"This is dell-tah too ait."
