1.4.5 Phonetic Alphabet
The words of the International Telecommunication Union (ITU) phonetic
alphabet should be learned thoroughly. Whenever isolated letters or groups
of letters are pronounced separately, or when communication is difficult,
the alphabet can be easily used. The phonetic alphabet should always be
used when transmitting call signs.
When it is necessary to spell out call signs or words, the following table
should be used. The syllables to be emphasized are shown in bold type.
