It is best practice to indicate initials as initials versus taking them for abbreviated words. Changing some word-groups can change the check of the message, while some simply imply that a word is written out; but both change the message, which should always be avoided. One example of this is changing NJ by reading it as “New Jersey” instead of “initials november juliette” or “initial group november juliette” which would change the word count as well as alter the original message. Another example of this is changing KHZ by reading it as “kilohertz” instead of “initials kilo hotel zulu” or “initial group kilo hotel zulu” which, while minor, alters the original message that was sent, which should always be avoided.
