Sec.  220.29  Statement of letters and numbers in radio communications.



    (a) If necessary for clarity, a phonetic alphabet shall be used to 

pronounce any letter used as an initial, except initial letters of 

railroads. See appendix A of this part for the recommended phonetic 

alphabet.

    (b) A word which needs to be spelled for clarity, such as a station 

name, shall first be pronounced, and then spelled. If necessary, the 

word shall be spelled again, using a phonetic alphabet.

    (c) Numbers shall be spoken by digit, except that exact multiples of 

hundreds and thousands may be stated as such. A decimal point shall be 

indicated by the words ``decimal,'' ``dot,'' or ``point.'' (See appendix 

B to this part, for a recommended guide to the pronunciation of 

numbers.)
